Manual
Introduction
AKM is for control and monitoring of refrigerating plant fitted with an ADAP-KOOL® Refrigeration
controls system.
Depending on operating needs, AKM is available in four versions:
• AK-Monitor
• AK-Mimic
• AKM4
• AKM5
Two of these programs (AK-Mimic and AKM5) can show a display of a supermarket's cooling sites.
Placed opposite each refrigeration point are names, symbols and temperatures, so that the operating
situation of the plant can be followed from just one display.

Introduction
Description of system
System software type AKM is a programme that can be used with the ADAP-KOOL® refrigeration
controls.
System layout
The individual controllers are connected in a network with a two-core data communication cable. To
gain access to this data communication, a gateway type AKA 245 or a system manager AK-SM or a
system controller AK-SC or AK-CS has to be connected.
There are two types of gateway with different functions:
- PC gateway (AKA 241)- the controllers’ connection to a PC.
- Modem/PC gateway (AKA 245) / TCP/IP - the controllers’ connection to the telephone network.
The other units can be connected via TCP/IP.
When the programme is installed, the following functions will be available:
- Daily user interface with alarm reception, alarm history, overview lists and log presentation.
- Technical user interface with controller settings and registration of actual temperature performance.
Operation
The programme has been designed with a graphic user interface in the MS Windows programme. It
is a requirement that the computer is a Windows-based PC. The requirements are mentioned in the
installation guide.
Users of the programme may be authorized to carry out all functions or only selected functions in the
programme.
This manual provides an overview of the various menus. Sections that are somewhat longer than others have been included at the end of the manual as appendices. References to the respective appendices can be seen in the table of contents and the current menu sections.

AKM
Logon / Logoff
Logon to AKM
When the programme is started, access is given to a number of defined control functions, but not until
the user’s identity has been defined in the programme.
At logon, initials and password are entered.
A user with the initials AKM1 and keyword
AKM1 has now been establis­hed. Use it for the
establishment of a new “superuser” having access
to all functions.
Delete the “AKM1” user when general access to
the system is no longer required.
When Logon has been activated the user is allowed to operate the functions that have been authorized in the “Authorization” menu.
By selecting the “Auto start” function, it is possible to initiate a specified function directly from Logon
(see. later in the section "Change autostart"). When Logon is used, the user’s name and the Logon time
are entered in the “AKM Event log”.
Logoff
When logoff is used, the user’s name and the logoff time are entered in the “AKM Event log”.
Log off by pressing F3 or the button at the bottom right-hand corner of the screen. The program will
then continue to run in the background of the PC.
Use the "Access"/"Exit" function to completely stop the program.
Plant Archive
This function maintains the contact to a defined network, even if you change around between the
different menus in the AKM programme. A telephone connection will for example be kept open when
you change from one function to another function in the AKM programme.
The contact will be interrupted in connection with one of these events:
- operation of “Disconnect”
- ”Logoff”
- if the programme registers that there has been no data trans­mission for two minutes (can be set)
to or from the network in question. If the contact is interrupted for this reason, a new contact will
automatically be established when a function requiring communica­tion is started.
En system address / DSN address is buid up
in 4 levels:
aa = Domain (0-64)
bbb = Subnet (0-255)
ccc = Network (0-255)
dddd = address (0-1023), Gateway=0125
or System manager=1001
Example on a address 12.010.255.0125
There is access to the structure via the
"spanner button' on the top bar.
Select the required network and click "Connect“.
It is the same image that is used to establish connections to frontend via TCP/IP. See Installation Guide
AKM Manual RI0XBh02 © Danfoss 11-2010

Info: The buttons on the top line have the following functions:
Refreshes the plant overview and compresses the plants, so that only Domain and Subnet are
displayed
Updates the window with the refresh plants
Displays extra information entered in connection with the plant setup
Displays the controllers that are connected to the plants setup in the plant overview
Sorts the plants by name or the DNS information with which they are programmed
Opens the setup window to establish or modify plant information
Print function, which prints out information for the selected unit or group
Erases a selected plant in the overview
Activate/deactivate Callback when connected to a plant. With Callback the selected plant will
establish the connection and thereby pay for the telephone connection.
Alarms
Alarms can be received from the different controllers in the system which may be due to:
- Regulating problems
- Connection of new controllers
- Removal or failure of a controller
All alarms are first transmitted to the network’s front end e.g. master gateway and other system units
which contains information as to how the alarm is to be dealt with.
If a PC with the AKM program is defined as an alarm receiver, the programme will receive all alarms.
When an alarm is received, it is immediately shown on the screen. The alarm is at the same time entered on a list.
New alarms
When an alarm is received, a bell will appear on your screen. A click on the bell will provide you with
an analysis of the alarm.
A right-click on the bell in the process line displays:
The different menus for the alarm bell are, as follows:
10
Manual RI0XBh02 © Danfoss 11-2010
AKM
Alarm accept picture
This function brings the alarm message to the front position on the screen. It will then be possible to accept the alarm. “Accept” is only an indication that the user has seen the alarm. The
alarm is not cancelled.
.
If the alarm is accepted, the time (PC-time) of the acceptance and the user’s identity will be
entered on the alarm list.
If you do not want to accept the alarm at the present time, the picture of the accept menu
may be hidden behind the other picture displayed on the screen (click the picture that is to be
active).
The different fields in the alarm message have the following meanings:
System Address
Here see the sender of the alarm. If it is a system alarm, an AKM programme will always be the
sender of the alarm.
Active / cancelled
The status of the alarm is shown here. (The “History - Alarms” section explains the meaning of
status value). An active alarm is displayed in red.
A cross over the alarm bell signifies that the alarm has been cancelled.
ID code or type
For controllers an ID code may have been added. This ID code can be shown as additional information, when there are alarms from the controller in question.
In connection with system alarms the line will provide information about the type of the alarm.
Received
Indicated here is the time the alarm is received in the system unit (e.g. gateway-time) or system
alarms has appeared in the AKM programme (PC-time).
Alarm text
The error message with a text is indicated here.
Controllers: Please refer to the literature for the relevant controller.
AKM programme: System alarm. Error for recipients, etc.
Custom text
For the controllers, a language-based text for the alarm message may have been entered.
List unaccepted AKC alarms
If this menu is selected, you move directly into the complete list of unaccepted alarms. Operation of the alarm list is shown in the section History.
List unaccepted system alarms
If a system alarm is to be accepted, it must first be selected and then accepted by click “Accept”.
Several alarms can be selected at the same time by.

Plant overview
Graphic plant overview - Mimic
If you have installed AKM5 or AK-MIMIC on your PC, you can choose to see the plant overview in two
ways, either as a graphic presentation of the plant overview or as plant lists. If your version is AKM4 or
AK-Monitor, you will see the plant lists only.
If applicable, consult Appendix M as well.
In this section we have a look at the functions that are available for the Daily operation.
Before you can use the function, it must be prepared, as described in the section "Configuration" /
“Setup plant overview”.
The functions moreover require that you have contact to the plant - either directly on the plant or via
a modem connection or TCP/IP.
Procedure
1. Start the "Graphic Plant overview" menu
2.
When you open a plant you will have two
approaches, depending on how the setup
has been defined. Either there is a display
as under point 2, where you have to select
one of the plants yourself, or the setup may
have been made in such a way that you
skip this selection and the plant overview
is shown directly (See “Setup” - “Start
Picture”).
3. Select the plant you want to see, then click "Mimic".
4. You will now see a drawing of the plant, and at the bottom there is a number of buttons you can
operate.
Logs: Alarms:
Service:
Here you can see curves of the collected temperature values.
Here you can see the alarms there have been, and when. And whether they are still active.
Here you delve right into the controller’s function. Only use this function if you have refrigeration-technical
experience. (The use of this button may have been opted out when authorisations were assigned).
Change: Here you will have access to the functions that are represented with a symbol. You may for example correct
a temperature setting here.
Zoom in: Here you can have some of the plant enlarged on the screen.
Fit:
The drawing is adapted to the screen.
Print:
Here you obtain a printout of the actual screen display.
Back:
This function is only used, if you have a short-cut function to another drawing. From this drawing you may
then return to the overview picture.
Log off
Here you can log off, so that no one else can change the settings without being authorised to do so.
Close:
Closes the picture.
(right-click on the Mimic image for easy access to the first four functions)
5. A normal situation at this place would be that temperatures are displayed at the individual refrigeration points - maybe also a symbol with a couple of water drops. "Water drops" indicate that defrost
is going on. An "ice crystal" indicates that there is refrigeration on the section. If an "alarm bell" is
shown the alarm must be investigated. But otherwise the principle of this display is that symbols are
only shown when the plant’s operating situation is abnormal.
If there is a refrigeration point you would like to study more closely, first select the icon with the
mouse key, then use one of the buttons at the bottom of the display.
Shown on the next page are some examples of operation.

Operation
If you want to have a closer look at one of the regulations, you must first select it. You will then have
the following options:
Refer to earlier temperature performance
Select Logs
Select the data collections you wish to see, then click "OK". You will now see the curves. (The log
function has been described in the section History.)
To see alarms
Select "Alarms"
Select the alarms you wish to see, then click Alarm.
You will now see the list of alarms. (The alarm function has been described in the section History.)
To access settings in the controller
(The function may be blocked from the authorisation menu). Select "Service".
Instruction in further operation functions may be obtained from the controller’s documentation:
“Menu operation via AKM”.
To change a temperature setting or start an extra defrost cycle
Select "Change"
If you highlight the 'Setpoint Only'
function, the only parameters that
will be displayed are the ones in
which a change can be made.
Select the parameter you want to change and move on to the function by click "Change".
Now correct to the required value.

Plant lists
A setup must be performed before you can see the display below. This is outlined under
"Configuration"/"Setup plant overview".
Here you will - with the setup selected here - have three approaches for the status of the refrigerating
plant, e.g. Overview, Defrost and Setting. You choose between them by click on the required line
with the mouse. All types of information can be shown either in the shape of lists or bargraph (there
is a button for either option). If you select “List” you will receive a presentation of texts where it is
possible to react to the information, whereas “BarGraph” will provide you with a purely graphical
display.
The three lines shown
here are examples.
In your plant there
will probably be other
names and texts than
the ones shown here. In
this document the three
approaches will guide
you in the principles:
- Display of temperature
- Start of defrost and
- Change of temperature
setting
1. Overview of air temperatures and alarms
Click on the line “Overview” and activate one of the buttons, BarGraph or List.
"BarGraph"
If you select “BarGraph” you will obtain an easy-to-grasp, graphical display of the current
temperatures at all points of refrigeration, and alarms from the controllers (high-temperature
alarms) will likewise be indicated. This is a display you could typically have on all the time.
The bargraph will have the colours that were defined during the installation.
The display automatically changes bargraph every two seconds, but if you want to see the status of
a special bargraph, all you have to do is to indicate the bargraph with the mouse and click the left
mouse key.
14
Manual RI0XBh02 © Danfoss 11-2010
AKM
When you release the mouse key again, the programme will return to automatic display. You may
also change between the parameter name and appliance/room name under the columns by click
with the mouse on the horizontal text key.
“List”
If you select “List”, you will obtain the same data as above, but now in text form. This window
will at the same time enable you to see the trends of the refri­geration process for the connected
refrigeration points, and you can make printouts of the information and make changes of the
settings.
“Service”
The service button is for radical changes of the plant, so it should be reserved for the service
engineer.
"Alarm"
With "Alarm“ you obtain a list of the alarms from the controller in question. You can adapt the
filtration of alarms to this approach.
"Logs"
With "Logs“ you get access to the logs of this controller.
"“Trend”
With “Trend” you obtain an overview of the temperature.
Select the line or lines for which you require a trend curve. You may select as many as eight,
either by drawing the mouse across the lines or by activating individual lines by keeping down
the Ctrl key and click on them one by one.
Now activate “Trend”.
AKM Manual RI0XBh02 © Danfoss 11-2010
15
That will set up a new window on the upper half of the screen where you may choose to have
curves drawn into the graph at 5 to 90-minute intervals. The chosen period of time is marked
with start and stop times at the bottom left and right, respectively. (You may select a new
period of time in the “Time scale” field).
It is possible to remove the graph’s grid. Also the colours can be removed. In that case the
curves will instead be numbered. And if you prefer a black background and white curves, you
can invert the display.
At whichever point of the curve you click the mouse, the time will be indicated under the
graph. This means that you are able to identify the exact time of any deflections within the two
“time extremes” at either side.
The Trend window furthermore contains a scroll bar which can be used for changing between
the name of the refrigerating point and the temperatures that are being measured.
The Logs button must be used to save a Trend curve.
“Change”
With “Change” you can change a parameter. See the next section.
“Print”
Print the curves in the display screen.
2. Defrost ‑ times and extra defrost
By activating this line in the Plant overview you will obtain - in bargraph or table shape - an
overview of the location of the individual refrigeration points during defrosts. You will furthermore
be able to see how much time has been spent on the last defrost at each individual point. Among
other things, this function can be used for identifying abnormal ice formations on an evaporator or
defects in the heating element carrying out the defrost. If you use the bargraph display, you obtain
a very clear picture where you can all the time see how the defrost is proceeding.
With this function you can also override the automatic defrost, if a refrigeration point should require it. This is done by click the line for the current cooling site. Next, click Service, then Defrosting
control, and then start defrosting:
16
Manual RI0XBh02 © Danfoss 11-2010
AKM
(it is normally in position OFF). Now click the “Change” button.
A small window will now appear in the middle of the screen which confirms the OFF setting, but
makes it possible for you to change to ON. When you click “OK”, the extra defrost cycle will be
started. This is confirmed by the figure 3 in the status field on the “Defrost cond.” line. (The setting
returns to OFF, but the defrost has been started).
3. Setting of air temperatures in refrigeration appliances
Here you can see how the actual air temperature at each individual refrigeration point in relation to
the set value - and you can change the setting.
With the Trend button you can see the relation between the required temperature and the actual
temperature - either in graphical shape or as a table. This is a good control that the plant is running
the way you want it to.
If you want a temperature setting to be changed, first click on the line “Setting of air temperatures”
opposite the relevant refrigeration point. Now click the “Change” button. A small window will now
appear on the screen.
When the desired value has been set, click "Ok".

History
Alarms on AKM
In this section saved information pertaining to the refrigerating plant can be seen. This information
may for example be used for the veterinary authorities requiring documentation for a refrigeration
process during a period of time, or for the refrigeration engineer who has to see what happened in a
specific show case two weeks ago.
When you select “Alarms”, a picture appears where you can view alarms from the complete list of
alarms. The display shown below will appear after the first filtration. See the display on the next
page. Here, the "Views" button has been activated.
The complete list of alarms will be displayed, if you select “Total” in Period and then “View”.
If you only wish to see part of the list, you may create a view.
The view may be based on the following four parame­ters:
1. "Period"
Select either year, month, week, day or hour.
Now select the beginning or end of the period.
2. "Address filter"
Choose between one of the following three selections:
a) System addr.
Settings in this field are entered in four fields.
aa = Domain (0-64)
bbb = Subnet (0-255)
ccc = Network (0-255)
dddd = (0-1023). 0125 for AKS 245. 1001 for AK-SM 720, AK-SM350, AK-SC 255 and AK-SC
Example of an address: 12.010.255.0125. See "Plant archive", page 9.
b) Site ID Code
A network may be described with a name (enter the name in the field. E.g. “Supermarket-03”).
c) Controller ID Code
A group of controllers in different networks may be described with a name (enter the name in
the field. E.g. “Cold-showcase-xxx”).
3. "Alarms"
Select accepted or unaccepted alarms, or both / or just all the active alarms.
The selection function for "Still active" is only adequate if the alarms are received and accepted
from the same PC (if alarms are routed to different recipients, the programme cannot perform a
correct selection).
Alarms from the alarm list can be "hidden“. See next page.
4. "Alarm Text filter"
Here you can filter identical alarm texts, e.g. high temperature alarms, that may either be the controller’s own texts or texts addressed to a user defined description file.
5. When there is an alarm a pop-up window with the alarm text appears on the screen. If the function
is not required it may be removed.
18
Manual RI0XBh02 © Danfoss 11-2010
AKM
After the filtration, click "View“.
Note the heading in the display. If the depicted period has been filtered further, it will appear from
the heading in the picture.
For each alarm the following information is given:
- System address (network and address numbers).
- Site ID Code
- Controller ID Code
- The alarm text
- A customer defined text, if applicable
-  Alarm status
(The colour of the alarm text is related to the status value).
-  The time when the alarm has appeared and cancelled

Logs / Curves
General
The function can treat the data collected from the different logs. There can be several types of logs that
originate from several different collection points or different collection methods.
They are saved in three data bases.
• AKA LOG has data from a gateway AKA 245
• AK-SM LOG has data from a System Manager, AK-SM
• AK-SC LOG has data from an AK-SC 255
In the respective displays it is necessary to select one of the three data bases.
The log function is discussed in Appendix E:
To display the very latest pieces of collected data, a manual data collection must be performed, and
the data must be saved in the AKM program.
The manual collection must be performed using the icon at the bottom of the display screen:
Data base
Right-click
Then click

Curves
This function enables the PC display in graph form of the different data collections in the log function.
They can also be printed out as graph curves or in table form.
The established logs can be seen in the right field.
The various logs can be marked and then given a name and title as a means of help. This name and
title can then be seen in the field to the left. Here, several lists similar to the actual desired logs can be
created.
Use this order when you wish to see log readings:
1. Select the data base with the reading, e.g. "AKALOG"
2. Select which readings are to be shown by marking them in the right field.
3. Select period, e.g. "Daily"
4. Select the time using the scroll function (date and time can also be used, but only if you have selected "User Defined" as the period)

Export logs
This function makes it possible to transfer a data collection to a CSV file. The file can then be opened
later as a graph in Excel.
Only data which have been stored can be transferred. New data that still lie in the memory (RAM) must
first be stored on the hard disk before they can be transferred (data can be stored manually by click
the icon "AKA Log" / "AK-SC" or "AK-SM" in the process line and then click “Save logs”).
The display will show all the established log lists.
Select the data base on the bottom line or click "A name on the left" to select the group of readings (in
the field to the right you can see which readings have been selected).
If it is a specific reading, it can be selected.
The "Deselect all" function will remove all markings of the readings.
The time period for data collection is limited and “Export” must be clicked.
(A maximum of 128 logs can be selected for the same “Export”).
The programme itself will propose a file name that will be determined by the selected period of time.
D + date, if a day has been selected (yesterday’s date)
W + date, if a week has been selected (last full week. The date indicates the start of the week).
M + date, if a month has been selected (last full month. The date indicates the start of the month).
Y+year if year has been selected (all last year. Year indicated is start year)

Configuration
This section describes the setup of the system, i.e. how the AKM programme gets to know the individual controllers in the network, how the individual controllers’ different functions will be presented
on the subsequent displays and how the AKM program's functions must be set.
There can be contact to various system units (front-end), e.g. Gateway AKA 245. System controller AKSC 255, C-store AK-CS, system manager AK-SM.
Import Description
file
A description file contains information on a controller's functions. The file can be imported if there is a
processed file from a previous plant. If there is no file available, go on to the next function, "Upload". A
standard description file will then be uploaded from the controller. (Description files are described in
Appendix D).
The function copies an already made description file into the system.
The description file must be transferred from another AKM programme to e.g. an USB-key.
Change to e.g. USB-key, select the relevant file and click "OK".
The file will now be copied into the library shown.
If other description files are available from an earlier setup, they must be imported before you can
proceed to the next point: "Upload".
26
Manual RI0XBh02 © Danfoss 11-2010
AKM
Upload
This function "takes a look" at the DSN-Network to see which front-end and controllers (addresses) are
in the network. It will subsequently obtain data from the different controllers for a file in the PC. It is the
contents of this file the AKM programme uses for showing texts in the different displays.
Note!
If description files have been imported before this upload function is started, the texts from these
imported files will be used by the programme.
It is a requirement that router lines are set in all the affected gateways, before the upload
function is performed. Otherwise the function will not be able to communicate with all the
controllers in the network (see AKA setup, if necessary).
Other front-end (e.g. AK-SC 255) must be entered in "Plant archive" before the upload function is
used. This is described in the installation guide.
A system address/DSN
address consists of four
levels:
aa = Domain (0-64)
bbb = Subnet (0-255)
ccc = Network (0-255)
dddd = address (0-1023),
Gateway=0125
System manager=1001
An example of an address
is 12.010.255.0125
Only the network must be
set for "AKA".
- Enter network number in “Network” field.
For AK-SC 255, AK-CS and AK-SM, the Domain and Subnet must also be entered (click AK-SC to open
the settings).
- Decide whether information is required from the network (unit’s system address, code number or
software version).
Tick then “Net configuration” check box.
- Decide whether information is required from the controllers (standard description file with the texts
that appear in the controllers menu description). If yes, the "AKC Description" field must be ticked off.
If the file is already saved on the PC it will not be downloaded, as the existing file will be used instead.
If there is a difference between the new upload and the one already known by the programme, the
programme will ask if the new upload is to be stored in the PC instead of the earlier upload.
If no selections are made in the two fields, the earlier uploaded configuration will be used for the
coming settings.
Note! If a new controller is installed in the network, a period of up to five minutes may lapse
before it is registered by the master gateway. When the master gateway has registered the new
controller, a new upload must subsequently be performed for the AKM program.
As large quantities of data are exchanged during uploading, there may be a waiting period of
up to several minutes before the programme is again ready for use (the time depends on the
size of the system, and on whether a modem connection is used).
- Click "OK".
Depending on the selection made, data from an earlier uploaded network list or from a file which
just has been generated will now be shown.
Note
If an asterisk (✸) is shown next to a system address it means:
- That the address is new, or
- That there has been an updating of the unit’s software
If an exclamation mark (!) is shown next to a system address, it means that the attached ID code is also
used by another unit (system address). Correct the ID code, if you like, but the programme is perfectly
able to accept identical ID codes.
AKM Manual RI0XBh02 © Danfoss 11-2010
27
A code number indicated as UNKNOWN TYPE may be:
- a control panel type AKA 21 (it is automatically assigned an address No. 123, 122, ...)
- a unit with a software version not supported by the programme
- an error in a router line
- a conflict between a set system address in the unit and the master gateway's system address (network number).
Only when UNKNOWN TYPE is an AKA 21, can it be accepted. In all other cases the error must be corrected.
The numerical value in the MCB column is for your information and is only used in conjunction with
older controllers and the "Override“ function (appendix N).
ID code
To help you in the day-to-day operation, the different controllers may be assigned a name. Based on
this name it will be easier to operate the various settings than if the controller has only been defined
with one system address.
When the system address has been selected, click “ID code”. (The function is not possible for AK-SC, CS
and SM).
Enter an ID code, e.g. the name of the refrigeration appliance. Click “OK”, and the ID code will be stored
in the master gateway.
Custom file
Customer-adapted description files are used for entering customer-specific texts as a supple­ment to
the factory-coded text.
Later in the programme you may choose between two texts in the menus where the texts can appear.
Select one of the two texts by click "Default" or "Custom".
Before a customer-based text can be added, this text will first have to be entered. This is done in the
“Advanced configuration” menu.
In the “Select file” field you may choose between the factory-coded text (Default = fx. English text) and
the custom-defined text (Custom).
If a language-based text is selected, you must also select a file name where the text has been entered.
When a file name has been selected, it will be displayed in the “Connect file name” field. Now click “OK”.
(A file describing the factory-set English text will have the name “Code number + software version”).
If it is required that a custom file has to be removed from a controller again, it can be done, as follows:
Select the relevant controller and attach the factory-set file (Default) to the controller.
Delete
If there is an address that is not to be dealt with in the AKM programme, it can be deleted from the upload
picture. Select the address and click “Delete”.

Advanced configuration
This section contains the special functions that are not necessarily used, but which are present when
you have to:
- edit customer-adapted description files (see also Appendix J).
The following functions are available:
Edit Custom file
Delete Description file
Export Description file
Print Description file
Convert file (des/akc)
Check System Address
Edit Custom file
Customer-adapted description files (hereafter referred to as custom files) are used for en­tering
customer-specified texts as supplements to the factory-encoded text.
Later in the programme you may choose between two texts in the menus where the texts may appear.
Here you select one of the two texts by click “Default” or “Custom”.
Start by selected a network; select AKA or AK-SC.
You can then see which files are available.
Here you may choose between two types of files
a) if you click “Default”:
Shown here are all the description files in the
system known by the programme (up-loaded with
the function “Upload configura­tion”). The identification of each file consists of the controller’s code
number and version number;
b) if you click “Custom”:
Shown here are all the description files that have
already been customer-adapted and stored as
custom files.
If the programme uses one of the indicated files,
it can only be seen at one place: in the “Upload
configuration” display. The file name will here be
shown in the Custom file column, if it is attached
to a con­troller.
Select the description file you want to work with.
Level 1 of the selected file (controller) will now be shown.
On this level it is possible to carry out two types of editing:
a. You may enter a supplementary text for each line (menu group). When the text has been written,
click “Change” and the text will be shown in the Custom column. (These are the two texts on the
line you may alternate between during operation later).
AKM Manual RI0XBh02 © Danfoss 11-2010
29
b. The factory-set user limitation can be changed for each line. Select “Low” for functions that may
be operated by many users. And “High” for functions that may only be oper­ated by very few
users, e.g. service engineers.
Also correct the texts on level 2.
Each of the lines shown indicates a number of parameters where a supplementary text may also be
entered. It must at the same time be defined whether this parameter is to be included in the plant
overview. For alarms, a priority may also be defined.
Select a line and click “Edit”.
The line “Thermostat control” has been selected here.
Now perform two edit operations:
a. Enter the customer-specified text.
b. Put a tick in the “Plant overview” field against the parameters to be displayed in a bar chart or in
table format.
When a line has been edited, you must update the display by click “Change”.
When all lines have been edited, you must finish by click on “OK”.
When the "Alarm" group has to be changed:
Alarm priority
The priority of a given alarm is defined here. Priority 1 is assigned to all important alarms requiring
quick action, e.g. sensor errors or too high media temperatures. Priority 2 is given alarms on the next
level, etc. In the later setting of alarm routings (in AKM Alarm schedule) , different alarm priorities can
be routed to different receivers.
Alarms given priorities 2, 3 or 4 will not be shown by the programme "AK Monitor".
(The default setting for all alarm priorities = 1)

Save Custom file.
When you have finished editing the texts, click “Save”.
You may now save the revised file in two ways:
a. You can give the file a name which you determine.
b. You may choose to save it as a default file (it will update the existing default file which is used by
all controllers of this type).
Click “OK”, and the file has been saved.
Delete description file
The function deletes a description file found in the system (Appendix D contains an explanation of a
description file).
Select the description file to be deleted and click “OK”. (If the file is attached to controllers, a warning
will appear before the file is deleted. If you still wish to delete the file, it will be removed from the controllers which will subsequently use the “Default” texts).
If a Default description file is deleted by a mistake, it can be recovered by means of a new upload.
Export description file
The function copies an already made description file onto, say, a USB key
Select the description file to be copied and click “OK”.
AKM Manual RI0XBh02 © Danfoss 11-2010

Indicate where the file has to be copied and the name it will be given, e.g. A:NAME”, and click “OK”.
Print description file
This function prints all the parameters in a description file.
Select a description file and click “OK”. The text in the file will now be printed. Printouts can be made of
both “Default” and “Custom” files.
e.g.

Convert custom/setpoint file
The function can transfer "custom texts", "priority", "parameters selected for plant overview" and "user
level" from one description file to another, even if the two description files belong to different unit
versions or code numbers. It is advantageous to use this function when custom texts are found for a
controller, and this controller has to be updated with a newer software (fx AK-CC 450 version 1.40 to
AK-CC 450 version 1.50).
Texts can be transferred when the two basic texts are identical (identical “Default” texts), e.g.:
Custom file 1
Custom file (2)
Standard 1
Custom text 1
Standard 2
Custom text 1
xxxxy
Text for xxxxy →
xxxxy
Text for xxxxy
A Custom file has now been made which is not
complete. The file only contains the known texts
from Custom file 1, and must now be adjusted.
Open the new file in the “Edit custom file” menu
and adjust it for deviating and missing texts.
See the display on the next page.
32
Manual RI0XBh02 © Danfoss 11-2010
AKM
Use the following procedure:
- Select a file in the “From” field
- Select the code number and software version the new Custom file is to be used with in the field "To
type:"
- Give the new Custom file a new name in the field "Save As"
- Click “OK”, and the conversion is carried out
- Change to the “Edit Custom file” menu. In this menu you now have to go through the new Custom
file, point for point, and the required corrections must be made and new texts added.
The function can also convert a setpoint file from one software version to a newer one. The procedure
is as described above, but "Type“ must be selected as "Setpoint file“ instead of "Custom file“.
Check system address (addresses on AKA 245 only)
This function is used for checking whether there is a communication line to the established system addresses, or whether the “System address” menu has been set in a controller. Lines for several controllers
can be checked at one go. The function is chiefly used when new installations are made or in situations
where you check whether all controllers are present in the network.
Select one or more controllers
Activate one or more controllers and check them by click “OK”. The system will react by showing either
“OK” or “-”.
“OK” means that there is a connection, and a system address has been given.
“-” means that it cannot be found in the network, or that it has not had its “System address” menu set.
If the controller is not connected in the network, a “-” will appear after approx. 70 to 140 seconds.
If a “-” appears after a few seconds, the “System address” has not been set.

Network 2 / Store 2
Log 001...
Function
This function automatically exports a number of data collections from logs to a file. The quantity of
data and the export time are determined in the setup. The file will be a CSV file and can be read via
the "View exported logs“ function or via the "Excel" programme. The file contents will be a "window of
data" for the final full period, from which an export is received.
Prerequisite
A number of logs must be established which continuously upload data from given measuring points.
This is the data that is retrieved when the auto-collect function is activated in log setup.
(All the logs established can be seen in the field on the left-hand side of the display. It is on the basis
of this total list the individual export files have to be generated).
Setting
When an "Automatic export log“ has to be defined the following points have to be carried out:
1. Give the file a name.
2. Selecting a data base: AKA log, AK-SM log or AK-SC log.
3. Select one or more of the mentioned data collections on the left-hand side of the display. If you
select a network, the entire contents of the network will be marked off and any later establishment
of a log or parameter in the same network will automatically be included in the export file. If you
instead select on log level, any changes in the selected logs will be registered, but the establishment
of a new log, if applicable, will not automatically be included.
4. Set the time of the exported data.
The time (period) will often be a week or a month, but you may choose shorter or longer periods of
time.
• The data exported each time will always be data from the entire previous period from which an
export is received.
• It is only the data available on the PC at the time of the export that will be exported.
• To ensure that all data from a log are included, a period of time must be selected which is longer
than the time between two consecutive measurements (longer than the measuring times for the
individual parameters).
5. Set the types of logs that have to be exported.
If you select “AKA” / AK-SC, CS or SM all the marked measurements on the left-hand side of the
display will be uploaded. If "Service“ is selected, only part of the marked measurements will be uploaded (those defined as service log). If "Food safety“ is selected, only part of the marked measurements will be uploaded (those defined as authority log).
6. Set where and how the exported files has to be placed.
a. Set the path and folder.
b. At the time of export, time stamping and DSN number will be available and the file will be saved
in a site established as one of two. The other one will be the file name.
Set how you want this to be arranged:
• either where the site is a network number or the file name is the export time,
34
Manual RI0XBh02 © Danfoss 11-2010
AKM
• or where the site is the export time and the file name the network number.
7. Press "Save“ to save all the settings for the relevant file.
(If you wish to change some of the settings for an already established file, you can double-click on
the name to have the settings shown).
8. Now set the export time.
This takes place in the "Configuration / AKM Schedule”. See page 49.
9. The definition has now been accomplished. Start/stop of the export must take place from the schedule function mentioned under point 8.

Setup Plant overview
The following functions are available:
Graphic Plant Overview
Graphic Plant Import
Graphic Plant Export
Object editor
Plant Lists
Graphic Plant Overview
Before starting, ensure the following:
- There must be a drawing of the plant.
- The drawing must have BMP format.
- It must be placed in the folder with the other BMP-files (C:\AKM\AKLAYOUT\...)
- You must perform an upload on the plant, so that the program­me recognizes the controllers by their
respective individual addres­s.
1. Start the Graphic Plant Overview menu.
2.
Marking a name (first visible when the plant
and name are defined)
If you mark a plant, this will be the plant
that will pop up when you later open the
function from the “Plant Overview” user
menu.
Edit
If you have already been through the setup
procedure once and want to make a few
corrections, use this function.
Delete
If you have a setup which is no longer
required, delete it here.
3. Select New and you will obtain a display with this number of buttons at the bottom.
Browse
Start test:
Fit:
You use this button when you check your setup. The button changes text between Browse and Edit,
depending on the function you are able to change to.
Use this button when you check the setup. The button will alternate between the texts Start test and Stop
test.
This button will adapt your picture to the size of the screen. If there is a great difference between the size
of the drawing in the two situations, you risk that some of the contents of the drawing will be missing
when it is displayed. This is because Windows is forced to delete/stretch the individual pixels in the drawing when it changes size.
4. Use the “load picture” button at the bottom left and continue by selecting a picture for the plant.

5. Once you have a picture of the plant, your next job will be to
place the appropriate control functions opposite the given
refrigeration points.
From “Edit Toolbox” you select: database (AKA or AK-SC) and
here after:
a. The network number.
b. The controller’s address.
c. A controller’s code number - if you do not have direct
contact to the plant. If you do have contact, the programme will show it.
d. Object Name
Some controllers will have several control sections,
(evaporator) e.g. an AKC 116 which has three of them.
The sections will be named A, B and C.
e. Reference
Select a name here if you want to create a short-cut key
to another drawing or to an object which is linked up
with a drawing (also known as “application object”).
f. Give the control a title
g. Now move the cursor to the drawing and place the icon
at the refrigeration point to be controlled by the controller section.
6. Repeat 5d to 5g, if the controller has several sections.
7. Repeat points 5 and 6, until all refrigeration points have
been assigned an icon.
8. Save the chosen setup with name and title.
Control 1
You now have to check whether the symbols actually show up
in the drawing, the way you expect it to.
1. Click the “Simulate” button at the bottom of “Edit Toolbox”.
2. Click the Browse button at the bottom of the display.
3. Click “Start test”
You will now observe that the different symbols will be
flashing at the different refrigeration points.
Take a look now at the location of the individual symbols,
can they be seen clearly? If they are correctly placed, you
may proceed, otherwise you must move back and move the
icon a little.
4. Conclude this control by click “Stop test”.
Control 2
Now you must check whether there is connection to the
controllers.
1. Return to the picture where you place the icon on the
plant. (If you come from the above mentioned point 4, click
“Edit”).
2. Click the “Connect” button at the bottom of “Edit toolbox”.
3. Click “Browse”.
4. Click “Start test”.
5. The programme will now upload data from the individual
controllers, and this may take a minute or so, depending on
the size of the plant. The uploaded data will now be shown
at the individual refrigeration points in the shape of, say, a
symbol and/or a temperature display.
6. Conclude this control by click “Stop test”.
Closing down
Conclude the setup by click “Close” and return to the programme’s main menu.

Edit Toolbox
This is where you select data from the individual
controllers. If it is in your way, you may move it
around on the screen by grabbing hold of its
top line.
Network
Here you select the network number you have
assigned to the plant.
Controller Address
Here you select the address assigned to the individual controller. If you have given the controller a
text via the “Customer-defined text” function, you
will be able to see the text here.
Controller
Here is a list of all the controllers and software
variants that are supported by the programme.
When you have contact to a plant, you will be able
to see directly what kind of a controller is installed
in the plant.
Object Name
Here you will see some groups of parameters the
controller can make use of. An AKC 115 will for
instance have two groups - one for the A-section
and another for the B-section.
Each of the groups will have some selected parameters, but you cannot see these here. These parameters may be, say. alarm, temperature, defrost, etc.
- and they have been established beforehand.
Reference
If you select something from this box, you will
create a short-cut icon that will connect you to
another picture (which you will of course also have
to set up, like this picture) or to an application
object. In this way you may have a shop layout on
the screen with, say, a short-cut to a picture of the
compressor room.
Object title
Here you may give the icon a name, if you have
not already written a name directly on the
drawing.
Oops!
If you have clicked the mouse key once too much
on the drawing, you will place an extra icon there
with exactly the same functions as the first one.
Click “Delete” to remove the extra icon.
Which is which?
If you want to know which controller belongs
to which refrigeration point, click the icon at
the refrigeration point. The contents in the “Edit
Toolbox” will now show the given data.
Correct
If you wish to correct the contents of an existing
icon, first select the icon, then carry out the
change in “Edit Toolbox”, and finally complete the
change by click the icon again.
Limitation
You can max. establish 200 icons (refrigeration
points) in an overview picture.
Reaction time
If you have many icons on your overview picture,
you will similarly have a long reaction time - it
may be up to five minutes before all the data have
been uploaded.
Subsidiary lines
If you require subsidiary lines for placing your
icons in the drawing, activate the function by
means of the right-hand mouse button.

Import Object
If you have a graphical plant overview from a previous plant, you can download it to the PC with this
function. (The file must be exported with the function mentioned below)
You may for instance use the copy:
- as safety copy, if the shop’s PC suffers a breakdown.
- for your own PC, if you require service via the telephone network.
Before starting the import function you must decide whether some of the files on the PC are to be
overwritten, if the import function comes up with a corresponding file.
1. Select the current file and click "Import"
Export Objects
Controller object
This is a generic term for
- Standard object and
- Application object
Standard object
This is a collection of the, say, 5 to 10 functions that are required, if the
controller is to show them graphically. So both the functions and the
icons will be depicted on the drawing of the plant.
There is at least one standard object for each software version of a
given controller. (A factory-defined standard object will be named
“Default”).
1. Select the setup that is to be copied,
e.g. Super 1
2. Select the object types to be included
(all of them or only part of them)
3. Give the copy a name
4. Select where the copy is to be placed, e.g. A:
5. Press Save

Manual RI0XBh02 © Danfoss 11-2010
Application Object
This is an extended function of the above - a function where the
object is linked up with a drawing of, say, a refrigeration appliance.
MIMIC object
Both standard objects and application objects of the entire plant are
collected here. The drawing of the plant and any references (shortcuts)
are also included, if you have used several drawings.
AKM
Object editor
1. Start the programme from the Object Editor menu
All controllers in an ADAP-KOOL® refrigerating system have a description file.
This description file is either uploaded
from an AKM programme via the Upload
function or imported to the programme via
the Import function. This is the description
file you will see in the field to the left. The
description file shows all the parameters
that can be set and read in a controller.
Load
Used when you make corrections in an
existing object.
Select an object in the field to the left and
click “Enter”. The contents of the object will
now be entered in the field to the right.
2. First you must identify the required controller with the relevant
software version. Then it will be possible for you do one of three
things by click:
- Load
- New or
- Copy
In connection with New or Copy you must state the name of
the new object
Save
Saves an object you have been working on.
New
Used when you wish to construct a new
object.
Copy
Used when you wish to construct a new
object based on an already known object.
Delete
If you wish to delete an object, select it in
the field to the left and click Delete. (You
cannot delete an object from the list if its
parameters have been entered in the righthand field).
Close
Switches off the display.
Finish the display with OK.
3. You now proceed with the object in the field at the right-hand
side
(segment of the
above dis­play)
It is via this display you have to select the various parameters
for the object.
Give the object a name
You do this by selecting the code number
and software version, or write it yourself if
it is not found on the list.
Also give the object a name, so that you
can recognise it - or you may select a name
from the list, if the object is to be given an
already existing name.
An object will consist of all the parameters
placed by you in the field. You can see
whether the parameter has been defined
to be shown with a value or with a symbol.
Limitation
You may have up to 26 different parameters to choose from. If some of the
parameters are used for displaying both
a value and a symbol, you will have a corresponding number of additional values
over and above the 26. If you try to define
more than the 26 different parameters, the
last ones will disappear when you finish
the function.
Load Pic
Here you select a picture if you wish to
construct an application object.
Add
Starts the definition of a new parameter for
the object.
Modify
Used if you wish to make corrections in one
of the shown parameters.
Remove
If there is a parameter or a picture you no
longer require in the object, select it and
click “Remove”.

4. - If it is standard object you are constructing, skip this point.
- If it is an application object you are constructing, you have
to add a picture to the field.
Click “Load pic” so that you may select one from the menu
below.
We have drawn some general background
pictures of various refrigeration appliances.
You can use the picture that best suits your
application, or you can make a new one. If
you make a new picture, it must be in BMP
format.
If you have drawn another background picture, move the file into the folder with other
background pictures by using Windows
Explorer.
Path: C:\AKM\AKLayout\AKAppl
When you have selected a picture and
concluded this menu you will see that the
drawing appears as a parameter in the
earlier menu.
Select a picture and finish with “Open”.
5. Click “Add” so that you can add a new parameter. Or you may select an already existing parameter and then
click “Modify”.
You can now see the functions and parameters found in the
controller for which you are now making an object.
It is from this menu you must select the parameter you wish
to define for the object.
In a measurement you are only allowed to
follow a value which is transmitted from the
controller.
In a setting you also follow a value from the
controller, but here it will furthermore be
possible for you to change the setting in the
controller.
When you later change this value from the
plant overview, the controller will register
this and subsequently send the changed
value to the programme.
Show as
- If it is a temperature or pressure measurement, select “Parameter value”.
- But if it is an operating condition in the
controller that has to be shown as a symbol,
select “Symbol”.
(An operating condition may also be shown
with a numerical value, if you prefer it this
way).
6. First, select a line in the “Functions” field.
7. Then select one of the two parameter types - either mea­
surements or settings (there will be a choice of different
parameters in the right-hand window).
8. Now select one of the parameters in the right-hand window.
9. Finally select how you want the numerical values belonging
to the parameter to be shown - either as a symbol or just as a
value.
- If you have selected value:
Define the text you want to be shown before and after the
value.
If you wish to use the texts already found in
the controller, put a cross against the two
fields “Use parameter text”. But if you require your own text, write it here. Example:
“Air temperature” -21 “degrees”. Or you
may select:
“Air temperature” -21 “°C”.
If you require a display with another fount
than the one suggested by the programme,
you can change the fount from this picture.
Finish with OK.

- If you have selected Symbol:
Define a symbol for a given value which the programme
receives from the controller.
a. Click “Add” to start the definition of a display.
b. Select a lower value and an upper value (that may be the
same value).
c. Click “Select” to define the icon to be shown for the selected
values.
You have to define the symbol you wish to
see for a given operating condition.
If the parameter value is to be between 0
and 10, you can define different symbols
for different values, e.g.:
Symbol a: for 0 and 1
Symbol b: for 2
Symbol c: for 3 to 7
Symbol d: for 10
If it is a compressor capacity you wish to
output, for example, you may choose to
have it output both with a measurement
and an icon.
-The measurement will show the capacity
in percent.
-The icon will show that the compressor is
operating.
(This will require two parameter selections - one where you select measurement
and another where you select an icon. In
selecting the icon you then define that a
compressor is to be shown for the values
between 1 and 100).
When such a value is subsequently received from the controller the programme
will show the icon you have selected.
Select an icon and finish the display by click “Open”.
d. Click “Update”
You will now be able to see the selected settings in the field
to the right.
e. Repeat points a to d, if there are other symbols that have to
be shown for other values for this parameter.
f. Finish the definition of this parameter by click “OK”.
10. Repeat points 5 to 9 for each parameter you wish to include in
the object.
11. The object is now ready to be placed in the plant overview. See
the “Setup” section.

Plant lists
A plant overview is a display showing selected measuring values or other relevant situations for the
plant. It may for instance be the temperature at the various refrigeration points, HACCP information,
whether defrost cycles have started, or whether there are alarms of a certain type.
You must now define this overview, and it is depicted either as a bar chart or as a number of lines with
current values.
You may also define additional overviews, so that one display for instance shows tempera­tures,
another defrosts, a third settings, etc.
If the plant is a small one, all these things may be shown in one overview, but that will re­quire that
max. 50 displays be selected.
1) In the menu, select “Plant Lists”.
2) Click “New”
- If the programme knows several net­works, a display will appear where you have to select a network. Do that and proceed to point 3.
- If the programme only knows one network, it will automatically move on to the next display.
3) From this display you may now establish one or more plant overviews:
All controllers on this network are now shown for the selected system.
a. Start by defining name and title on the list.

- Select “Custom”, if a number of user-defined texts are to be used.
c. Now select a controller, and after that the measurement or function to be displayed.
Shown to the right are the measure­ments and functions you may choose between. If a tick has
been placed in the “Parameters used in all func.” field, an additional number of selected para­
meters will be shown from the con­troller in question. These parame­ters were not defined when
the user-defined description file was set up, but are determined by the controller type. Select
also one or more of these parameters, if required.
d. The various measurements and func­tions are selected by click “Add”.
Parameters used in all
functions
Few parameters.
Only the parameters selected in
the Custom file.
More parameters. Only the
common group
of parameters

AKM Alarm Schedule
This function is used for routing of alarms via the AKM programme.
Defined here are the receivers, times and alarm priorities that are sent to the individual receiver.
One router table can be set up for a normal period of time, and another router table for “Holiday/Holiday period". (Changes between the two router tables can be made by indicating start and stop times,
or by making this change manually. See ”Holiday period”.
Note!
Alarms can be routed to an other AKM program, to gateways, to mobile telephone with SMS and to an
e-mail address.
The alarm routings set here are “copy alarms”. The AKM programme itself receives all types of alarms.
A system alarm cannot be rerouted.
The routing stops if the AKM program or the PC is stopped.
If an alarm is not transmitted to the defined user for one reason or another, a repeat routine will be
started. The routine will repeatedly try to deliver the alarm, and if it does not succeed in it, a system
alarm will be generated (this system alarm will also be entered in the “AKM Event log”). Appendix F
contains a description of the repeat routine.
The following functions are available:
Weekly
Holiday
Holiday period
Delay settings
Condition
To be able to send alarms as e-mails a Windows
component called "Internet Information Service" must be installed. See Appendix L.
In Windows 7, Outlook or Outlook Express
must be installed.
Define Weekly
The function is used for setting the alarm routing table for a normal period. The setting is on a weekly
basis, and the set data are repeated week after week.
Settings in this field can be made in points
1 to 4.
bbb = Subnet 0-255)
ccc = Network (0-255)
dddd = address (0-1023) Gateway =0125,
AK-SC, CS=1001)
(The program itself will set the arrow in between
the two areas)
Example of an "address interval (window)" that
includes all networks and regulators for a plant.
12.010.000.0000->12.010.255.1023
The final result is displayed in this field.
This field displays the entered data that applies to
the line selected in the field above.
The values are not shown until they are set in the
next display. This is performed in the points on the
next page.
Add: Starts the creation of a new router line.
Change: Selects an existing router line if it needs
to be changed. Perform the change. End by
click "OK".
Delete If an existing router line is to be deleted,
select it and click “Delete”
Print: If you click “Print”, the whole router table will
be printed on the connected printer.
Setting up an alarm schedule:
1. Name the schedule in question
2. Set the period of time in which the schedule is to apply (For overnight periods between Sunday and
Monday, two router lines must be set: the first with a stop time of 23:59, and the second with a starting time point of 00:00)
3. Select the alarms to be forwarded based on their indicated priority levels. Priority 1 is the most important, 2 is the next most important, etc. (This setting is entered in the "Edit custom file" menu.)
Under "Priority" tick off this or the alarm priorities that must be routed in the given time period.

4. Select the plants (address interval) from which the alarms are to be forwarded
DSN numbers can be seen in "Plant archive".
After pressing "Add" or "Change", a display appears in which the alarm recipient is defined. The recipient can be: Other AK plants - Alarm receivers - Mobile phones - E-mail address.
Info
E-mail
To send an e-mail, the SMTP gateway must be configured.
Outlook/Outlook Express is installed and configured on the
PC on which AKM is installed.
Here it is only necessary to install the virtual server, as
described in the following pages.
AKM will use the settings entered in Outlook/Outlook
Express to send the e-mail.
Outlook/Outlook Express is not installed on the PC on which
AKM is installed.
Here the SMTP gateway must be configured based on the
information entered in the virtual SMTP server. The gateway must be configured by pressing the "SMTP Gateway
Configuration" button.
"Primary":
Enter the address of the alarm
receiver here. Please also consult
the Installation Guide.
"Alternative": If the system cannot get in touch
with the primary alarm receiver,
the alarm is sent to the alternative
receiver shown here.
"Copy":
This address always receives a
copy of the alarm.
Here the user must enter the IP address of the server and
the port being used (usually port 25).
It must also be indicated whether a user account is
needed for this server. This is done either by selecting
"Anonymous", if no account information is necessary, or
"Basic, if account information is needed. This information
must be entered in the "User name" and "Password" fields.
The settings described on the following pages must also
be made.
"Local AKA": If this field is selected, a copy of
the alarm is returned to the local
master gateway. It can only deal
with the alarm, if a printer is connected to it.
A printer must be connected to the master gateway, when alarms are sent to it.
"Auto accept": If this field is selected, the alarm will automatically be accepted.
"Only alarm status": Select the alarm status that is to be forwarded.
"SMS":
"e-mail":
46
If a GSM modem is connected to the PC, a sms message can be sent to a mobile phone.
The sms content will be the alarm text.
Note.
The AKM programme will check that the sms message is transmitted, but it cannot
control whether it is received. An acknowledgement of "Set alarm“ is not possible via the
GSM modem.
If an e-mail program has been installed on the PC, an e-mail can be sent to a given recipient. The contents of the e-mail will consist of the alarm text.
Note.
The AKM programme will check that the mail is transmitted, but it cannot
control whether it is received. An acknowledgement of "Set alarm“ is not possible via
mail.
E-mail installation on the PC is described in Appendix L.

By means of the above procedure the required number of router lines can now be entered. When all
lines have been entered, click “OK”, and the table is ready for use.
The information will then be saved, and the next time an alarm is activated (and meets the requirements in the schedule), it will be processed by the Alarm Router or be automatically accepted if it is
defined.
(Appears at the bottom of the display in the Windows line)
You can see the content by right-click the display and selecting "Alarms Waiting for Routing".
Define holiday
Settings are made in the same way as in the previous section.
Holiday period
This function diverts alarms during a specified period (holiday period).
1) Definition of alarm receivers and times is performed under the above mentioned item "Define
holiday".
2) The alarms will now be redirected, if:
- A tick is put in the "Manual" field.
- A start and stop period is set in the time fields.
(The settings are compared with the PC’s time, day, month and year).
Delay
If you have a system where you know from experience that a generated alarm will normally disappear
again after a couple of minutes, you can omit routing this alarm.
For the given system you set the number of minutes by which an alarm has to be delayed. If the alarm
remains active when the time has elapsed, then the alarm will routed in a normal way, but if the alarm
has been cancelled within this period of time, it will not be routed.
You will always be able to find an alarm that has been generated and cancelled again without your
having been informed of it in the "AKM Event Log“ overview.
If you at any given time wish to check if there are alarms awaiting their time delay, you may activate
the alarm routing icon on the screen’s process line.
The delay function only applies to alarms routed via the AKM programme.
AKM Manual RI0XBh02 © Danfoss 11-2010
47
The display will show all the networks known by the programme via the upload function (Upload).
Select the network you wish to make changes in, set the number of minutes by which an alarm is to be
delayed, and now click "Change“.
When you have made these changes for all the networks concerned, they are ready for use; but the
time delays will not become active until you have selected the "Enable“ field. The Enable field applies
to all networks at the same time.
If you wish to use the function on a network you have not uploaded, but have access to nevertheless, write the network number in the field and click "Add“. The network will now appear with the text
"Unknown net­work“, but this is only because the programme has no knowledge of the stated network
configuration.
The time indicated for such an alarm will always be the time the AKM programme was received plus
the set time delay. In other words, the time at which the alarm becomes visible to the receiver.
AKM Setup
The functions in the AKM programme are set.
This is done during the installation.
See also the Installation Guide.

AKM Schedule
The function is used for starting a function based on time and must be carried out regularly. Export of
a log list, for example.
In this display you can see:
• The name
• Text explaining the name
• When the function is to be started next
• When the function was last activated.
• Function status. Normally the text will be "Success“, but if the function was not carried out satisfactorily it will be seen here. "Error“ will for instance be shown if data collection of a parameter is stopped
without the export function having been changed.
Setting
An activity in the schedule must be defined, as follows:
A "Log list" must be defined before it can
be selected in this display.
The definition takes place in the function:
"Automatic log export".
1. Give the function a name.
2. Select function (at the moment, only the "Log export function“ can be selected).
3. Select a list from the bottom field.
4. Via the other field set how often the function is to be activated and when, if applicable REMEMBER
that the period of time between two activations must be the same as the log export list’s period of
time.
If a start-up date and/or final date is required, this may also be set.
5. Finish with OK.
If the function has to be stopped temporarily, this can be accomplished by placing a tick in the field at
the bottom left.

Scan
This function checks whether there is a connection to all the AK plants (the gateways, SM, SC, CS etc.)
which the AKM programme must have. If this contact is not established, the AKM programme will
give an alarm. The control is carried out automatically by the AKM programme and performed at the
defined times.
When the scanning function has been started, it is indicated with the following icon:
When scanning is performed via a modem connection, this is shown with a “earth icon”. Here you can
see which network you are calling.
The function is set and started, as follows:
In this field, the system addresses for which the
AKM program controls the connection can be
seen.
Scan time: Time of the last scan performed and
found to be OK.
Status: "-" means that no connection has been
established.
A number indicates the number of scans found
not to be OK.
Next: Here it is displayed when the next scan is
performed and for which address.
Use the “Add” or “Remove” functions for placing
the system addresses in the respective fields.
In the bottom left-hand field, the system addresses that are not controlled by the AKM
program can be seen.
Below, in "Scan disabled", the scan function can
be temporarily disabled without changing the
setup.
By click "OK" the new settings are saved and the
process is restarted.
- Activate the Front-End that is to be set.
- In the “Scan on” field you place all the system addresses that the scanning function is to control
(select, and click "Add").
- In the "Send alarm as“ field, set how an alarm is to be sent. There are two options.
• System alarm
Here the alarm will appear on the PC with the message "System alarm“.
• Alarm
With this setting you enable the alarm to be routed on to the receiver defined in the AKM alarm
routing function (see Alarm table section).
- In the “Frequency” field you set how often the scanner is to control the relevant system addresses,
and when the first scanning has to be performed.
If you also want to check whether the external master gateway can call the AKM programme, select
the function ”Scan via Callback”.
In the key diagram you can see the times when the connection was last controlled and found to be in
order.
(Until the first control has taken place, ??????? are shown).
If the scanning function does not obtain contact with the system address at the given time, it will
repeat the scanning later to establish whether there is contact nevertheless. The number of repetitions
and the intervals between them are determined by the frequency set for the control. The following
applies to the set frequencies:
Hourly: two repetitions at 15-minute intervals
Daily:
four repetitions at 60-minute intervals
Weekly: six repetitions at 240-minute intervals (4 hours)
Monthly: six repetitions at 480-minute intervals (8 hours)
Custom defined: An alarm is activated after the final repeat attempt.
In the key diagram under status you can see the number of repeated attempts made without obtaining contact:
AKM programme repetitions / expected callbacks.
If no contact is established at the last repetition mentioned, an alarm will be given about two minutes
after the attempt.

Manual RI0XBh02 © Danfoss 11-2010
AKM
On the picture can be seen:
- The period of time during which the measurements are shown (time for full graph width can be set)
Note! If the time scaling is altered while data are being collected, all collected data will be deleted
and data collection will begin anew.
- Temperature range for all measurements
- A grid, so that it is easier to follow the curves, (the grid is activated by selecting the “Grid” function
- The different measurements can be shown in colours, (activate the colours by selecting the “Colour”
function). Numbers are shown in black/white.
- Invert switches black and white in the graph display.
- If the word “Logging” appears at the bottom right of the display, the measurements shown will be
stored on the PC’s hard disk.
- By placing the mouse cursor on one of the curves, and activating the mouse button, the value of the
curve at this point will be shown in a field under the graph.
- With the “Logs” button, a number of data collection functions can be started that are required in a
service situation. Data can only be collected as long as the trend function is on. The collected data
can later be displayed via the function ”Curves”.
• Give the log a name.
• Set how long the log is to be stored on the PC hard disk. When this period of time has expired, the
log is automatically cancelled.
• Set when the data collection is to start. (If the starting time is not filled in, collection of data will
start as soon as “Add” is clicked).
• Set the period data are to be collected.
When the four settings have been made, click “Add”, and the data collection can start. There will now
be one data collection for all the parameters selected for the trend function. When the collection
of data has started, this is indicated with an asterisk opposite the log number. If a data collection in
process is to be stopped before the specified time has elapsed, it can be done by click the “Stop” button. (The word “Add” is changed to “Stop”).
Collection of data is discontinued, if you leave the trend function!
Certain log names, for which there is no collection of data, are older files (named “demo” here). If you
no longer wish to store them, select them and remove them with the “Delete” function.
In the “Interval” field you can see how often data are collected. The length of the interval is determined
by a setting in the earlier display for the trend function. There is the following relation between the

Copy Settings
The function copies set parameters from one controller to another controller of the same type and
with the same software version.
AK controllers with extension modules must be treated differently. The function here will only copy a
limited part of all settings.
To copy between these controllers Service Tool AK-ST 500 has to be used.
Note! As large amounts of data are exchanged during the copying process, there may be a waiting period of up to three minutes before the programme is ready for use again.
There are three ways of copying a set of settings:
1) from one controller to a file in the PC
2) from one controller to one or more controllers
3) from a file in the PC to one or more controllers
Select one of the three options in the “Option” field.
1) from one controller to a file in the PC
Select AKC -> FILE in the “Option” field.
Click “Source” to select the controller from which the parame­ters are to be taken.
When the selection has been accomplished, the relevant controller’s address, name, code number
and software version will be shown in the “Source” field.
Click “Destination” to indicate where the parameters have to be copied.
Type in “NAME.AKC”, and click “Save”.
Drive and name will now be seen in the “Destination” field.
When the two fields “Source” and “Destination” have been establis­hed, click “Copy”, and copying will
commence.
2) from one AKC controller to other AKC controllers
Select AKC -> AKC in the “Option” field.

AKM
Programming
The function is used for making all the settings for a controller before the controller is installed.
The settings are stored in a data file which will later be copied into the relevant controller.
The procedure is as follows:
- Before programming is commenced, the AKM programme must be connected to a network with the
relevant controllers and the relevant software versions
- Carry out a complete upload. The AKM programme will then make a description file for the controllers
in question. (You are now able to continue your work with the file without there being any connection
to the controllers)
- Perform a programming, as described in the following section
- When the programming has been completed, store the file with a name
- Copy the file to a USB key
- Copy the file’s data from the USB key to the new controller via the “Copy settings” menu. (two previous
functions)
- Carry out a new upload on the other system, so that the AKM programme on this system too knows the
controller’s data (code number and software version)
Print
To print out a given file, select it and click "Print".
Now select the controller (file) to be set.
Your decision will depend on the file on which the setting will be based. This decision is made via the
“Select file” group:
“AKC setpoint” is selected when programming has earlier been made via "Default" or "Custom". The
stored file can now be reopened, after which corrections can be made. When the new settings have been entered, the file is stored with its earlier name (if it is a revision), or with a
new name if a copy is required with the corrections made. (If the file is given a new name,
the original file name with the original contents must be kept).
“Default” is selected when the function is used for the first time, and a custom file has not been made.
Select a code number with the relevant software version.
“Custom” is selected when a custom file has already been made via the ”Edit custom file” menu.
This custom file may for example contain language-defined texts or other information
entered by the user.
Collection can only be performed from one network at a time.
Select the name of the relevant file.
When a file has been selected, click "OK", and programming can be made.
Go through the individual functions now and make the required settings. When all settings have been
made, click “Save”.
AKM Manual RI0XBh02 © Danfoss 11-2010
59
Indicate the name of the file, e.g. “NAME.akc”, and click “Save”.
If no new path is indicated, the file will be stored as shown at the bottom of the menu picture. The file
may now be uploaded by selecting the function "Copy Settings".

AKM
Log Setup
Two types of logs can be defined. In principle it does not matter which type is selected, but the
decisive thing is whether the PC is switched off for periods of time, or whether the AKM programme is
stopped. If that is the case, select the type where data collection takes place in the master gateway.
- Collection of data in the PC
This type will from now on be called “AKM_Service_logs”. It is therefore a require­ment that the PC is
switched on and in constant touch with all the controllers. Neither the AKM programme nor the PC,
must be stop­ped. Collection can only be performed from one network at a time.
- Collection of data in the master gateway
This type will from now on be called “AKA log”. This type collects data in the master gateway, where
the data are stored for a defined period of time.
All data will at suitable intervals be transferred to the PC (the programme it­self calculates when
transfers are to be made but only if the "Auto collect" function has been selected). If you wish to
determine when the transfer is to take place, e.g. on a given weekday, you can set this via the "AKM
Setup\Advanced“ menu. (Remember to set the time period in the gateway high enough for it to
contain all the data before the transfer takes place). (Select 210 hours to obtain one week (210 x
80% = 168))).
If the PC is switched off, for example during a weekend, the programme will start picking up log
data about one minute after the programme has been re-started.
(Please note: If the network contains both a PC gateway and a modem gateway, the modem
gateway should be the master on the network. In that case the data communica­tion will not be
disturbed unduly when large amounts of data are sent out on the telephone network).
Log setup
This function
- defines new logs
- makes alterations in existing logs
- starts and stops data collection (log on/log off )
- update a created log or a new log in a master gateway
1) Start function
Indicate where to collect data:
Address xxx:125 is in the master gateway
AKM Service logs is in the PC

2) This display appears if a log is located in the master gateway:
Click “New”.
3) Select controller
Select the controller from which data has to be uploaded.
4) The log can now be defined.
a. Start by giving the log a name
The ID code is automatically pro­posed, but the name can be changed, if you wish.
b. Set the intervals
The time can be set between 1 and 240 minutes for service logs, and from 15 minutes and up for
authority logs.
62
Manual RI0XBh02 © Danfoss 11-2010
AKM
c. Select Disk Per. time
This is the period of time the data have to be stored on the PC hard disk. They may be stored for
up to 365 days for all types of logs, but the minimum storage time differs and is determined by
the type of log in question.
Important:
When data become older than the set time, they are deleted (they dis­appear for ever), and they can
no longer be displayed or printed. You must therefore set the time, so that data are present when you
want to have them displayed or printed.
d. The next three points are not vi­sible at "AKM service logs":
1. AKA Per.
This is the period of time the data has to be stored in the gateway. Data can be stored for as
long as 250 hours for service logs, and for as long as 960 hours for Food safety logs.
Important:
When data become older than the set time, they are deleted (they dis­appear for ever), and they
can no longer be displayed or printed. You must therefore set the time, so that data are present
when you want to have them displayed or printed.
If data is downloaded to the PC, the PC and the programme must there­fore never be switched off
for a period that is longer than the set AKA period.
2. Selection in Food Safety
When a selection is made in the “Food Safety” field, the log will be defined as a food safety
log and the lower interval time cannot then be set below 15 minutes. If no selection is made
anyway, the log will be established as a service log in the gateway - a Servicelog.
3. Used space
Shows in % how much space has been reserved for the defined logs (one log definition may
max. take up 25%).
e. Now select the type of text to be shown for the controllers.
- Select “Default”, if the ori­ginal text in the controllers is to be used.
- Select “Custom”, if a number of user-defined texts are to be used.
f. Now select a function group, and after that the measurement or func­tion to be logged.
Shown to the right are the parame­ters (measurements and functions) you may choose between.
g. The various measurements and func­tions are selected by click “Add”.
Up to 13 parameters can be selected in each log definition.
AKM Manual RI0XBh02 © Danfoss 11-2010

5. Save this log definition by activating “OK”.
The newly established log will now be shown in the earlier display:
6. If there are several logs to be defined, point 4 can be repeated. However, if they are logs for the same
type of controller and the same software version, the succeeding logs may be defined by means of
a copying function.
Select a log and click “Copy”.
a. The earlier log is seen at the top.
b. In the centre field you write the name of the new log, or you put a tick against it in the field “Use
Id-code as log name”. The general rule is that if you select one con­troller for this log, the log must
be given a name. But if you select several controllers for this log, a tick in the ID code field will
provide separation of the individual logs.
c. At the bottom you select the con­trollers the new log is to belong to.
d. Finish by click “OK”.
7. When the different logs have been defined, it is possible to:
- Start and stop
If data are to be collected, the log must first be started. Select and click “Start”. The word “On” on
the line indicates, that data will be collected.
- Activate auto collect
Before a collection of data can be stored on the PC hard disk, the data must be obtained from the
gateway. This can be done automatically.
Select the logs to be obtained and click “Auto Col.”. The word “Collect” on the line now indicates
that the data will be picked up automa­tically at least once a day.
See the installation guide. Here it can be defined when the data is to be collected.
The data can also be obtained manu­ally, e.g. in service situations, where the most recently collected data must also be included (data collected since the last automatic transfer).
64

may be selected for the same printing operation).
- Perform editing
Select the relevant log and proceed with “Edit”. The required changes can now be made (the
collection of data must be stopped, when the log has to be edited).
- Make deletions
If a log has to be removed complete­ly, select it and click “Delete”. (The log must be stopped,
with “Man. Collect”).
Logdata from AK-SC 255, CS and SM
To collect logs from one of the named front-ends, the log setup
must be made on the actual unit. See the respective manual.
Once the log set-up has been performed, log data can be
retrieved for AKM.
When the log collection function in AKM has been started, it will
be shown at the bottom of the display. See the information here
to the right.
The steps below define how the function retrieves logs for AKM:
The function can be selected in the process line/ AK-SM / SC log
Info
Once logs have been set up in e.g.

Restore Log Setup
Manual log retrieval
To manually retrieve log data, the
plant in question must be selected.
Next, the relevant logs must be
selected. Finally, press the "Collect"
button.
Food Safety
If the log is an authority log, it must
be marked here.
This function is used for adjusting a log setting in a master gateway. The function may for example be
used in systems where an additional AKM programme (for service) is connected, from which shortterm changes of the log setting can be arranged. When the service has been completed, the earlier log
setting can be restored with the function. Or the function may be used, if the master gateway is to be
replaced (when the programme is updated).
When the restore function is used, the exciting log setting in the gateway will be deleted and replaced
by the log setting known by the AKM programme from where the restore function is started.
If data has been collected, they will also be deleted.
If the collected data are to be stored, they must be transferred from the gateway to the AKM programme (the service version) before the restore function is used. (activate the icon for the AKA log
and perform a manual collecting)
Select the “system address log” that applies to the gateway in question and click “OK”.
Note!
The log collection known to the AKM programme must be 100 per cent identical with the entire
network to which the “Restore” function is addressed, to ensure that the individual log setups
can be delivered. If it is not, the log setup for a missing controller will be lost. This will happen if
the controller is turned off, or if a software version in it has been changed.

Setup
The function is used for the setup of AKA gateway's.
By means of this function you set:
- The clock function in the gateway
- Printers that are connected to a gateway
- Router tables enabling the different gateways to send information
- Port setup in gateways (speed of data communication etc.)
- Configuration of inputs and outputs DI 1, DI 2, DO 1 and DO 2
- Alarm receiver (receiver definition of alarms from control­lers)
In addition to settings, setup and communication events can be read.
Select a network and continue to the next display.
Hereafter select a gateway on this network and continue with one of the following settings:
Setting of clock function (RTC)
(It is only necessary to set the clock function in a master gateway. All other gateways, if any, have their
clock function set automatically from the master).
On entering the picture data is obtained from the relevant gateway. This is the following: year - month
- day - hour - minute - summer/winter setting.
Summer time
Set selection of “Summer time” function in this field.
OFF:
Clock function not provided with change-over to summer time
Manual: If this function is selected, the times of the change-overs must be set in the “Manual” field
Auto: Automatic adjustment of the clock is performed on the following days: last Sunday in
March and last Sunday in October
PC time -> RTC
When this button is activated, the PC’s time setting will be used in the “Real Time Clock” field.
If the PC time is incorrect, it should be set. “Control Panel” can be used for the purpose.
The times shown are transmitted to the gateway, when “OK” is clicked.
Note! On a network is it the master gateway that synchronises the clocks in the various controllers
connected to that network. It is also the master gateway clock function that time-stamps alarms and
messages received by all controllers on the network.
AKM Manual RI0XBh02 © Danfoss 11-2010
67
The functions controlled by the AKM program are time-stamped with the PC time, e.g. the time of a
printout and the time of an alarm receipt.
(PC time and gateway time should always be maintained identical).
Printer
This function is used for setting the printer output for printed messages.
“Top text” indicates the text at the top of each page of printed paper. The text can consist of both fixed
and variable text, such as date and time.
“Bottom text” indicates the text at the bottom of each page of printed paper. The text can consist of
both fixed and variable text, such as date and time.
(The printed pages will not be given a page number. If date and time are selected for both “Top text”
and “Bottom text”, you will be able to read several printed pages in their correct sequence).
“Page length” indicates the number of lines on each page.
“Job header” indicates the text at the start of each message. E.g., a fixed text with the word “Sender”
plus a variable text consisting of the address.
“Job footer” indicates the text at the end of each message. The text can consist of both fixed and variable text. An excellent way of separating messages is by putting a line (________) between them.
“Codes” indicates the functions to be entered in the above mentioned fields.
<time>
= hour
<time s/w> = hour with summer/wintertime indication
<date>
= date
<addr>
= sender’s address
<tab>
= tabulation (six spaces)
For example, a code can be inserted in the following way: Using the mouse, double-click on the
required code and then move the cursor to the position at which the code must be placed. Install the
code with a single click.
When “OK” is clicked, the entered data are stored in the gateway.
Example of printer setup:
Top text: Danfoss AKA gateway <date><time>

Enter baud rate and lifetime, if any (lifetime is used for modem and ethernet connections and is the
time the line is kept open without any communication on it).
Baud rate for the connected unit must be set to the same value!
The three fields with IP addresses and the Subnet Mask are only used if data communication takes
place via the Ethernet (see installation guide).
The "Initiate String“ field is used for initiation parameters for modem and ethernet connections. See
the modem or server manual for further particulars. A typical setting of initiation parameters is shown
in the field.
Port to DANBUSS
Enter address and baud rate (“Address” is set with the same value as that of the gateway address/DANBUSS operates with 4800 baud). Click “OK”, and the information will be sent to the gateway.
DI / DO
The outputs have been factory-set, as follows:
DI 1: Reset signal. Used when a printer is connected to the gateway
DI 2:
Switch function. Used when manual alarm routing change-over is employed
DO 1:
Relay function. Used for supply voltage, if a modem is connected
DO 2:
Alarm relay output. If the gateway is to be connected to an alarm horn
Only in special cases will it be necessary to change the settings.
The functions work this way:
DI
Printer Reset
The input is used for giving a signal when the paper is in place in the printer.
Optional alarm schedule
The input is used for manual change-over between the gateway’s alarm destinations "Default“
and "Optional“.
Power failure monitoring
If the gateway registers missing voltage at the input, it will cancel all alarms which it is capable
of receiving via the DANBUSS connection. The function also requires that you key in a time
from 5 to 240 minutes. If this time is passed, and voltage is still missing, an alarm will be transmitted about the missing supply voltage.
Alarm Relay hold reset
Pulse pressure is connected to the input. Pressure will reset the relay when it has been activated.
External DI alarm
The input is used to receive signals concerning alarms from another unit.
70
Manual RI0XBh02 © Danfoss 11-2010
AKM
DO
If the gateway is set to modem gateway, DO 1 will be locked, so that the output can only be used for
supply of voltage to the modem.
If the gateway is set to PC gateway, DO 1 may be selected on a par with DO 2.
None
The output is not used.
Alarm reporting
With this setting the relay will be activated when there is an alarm. Select furthermore whether
all alarms are to activate the relay, or whether you want to opt out alarms with a special status.
External watchdog
With this setting the relay will be vacillating with the set time period. It will then be up to other
controls to register that the gateway is "alive“. The relay will stop vacillating, if the gateway cannot get rid of the alarms. You must also set how many unsuc­cessful attempts will be required
before the relay is to stop vacillating (with setting = 0 the relay will always be vacillating).
Alarm Relay hold
The relay is activated when an alarm is received with a selected status. It shall remain so until
the reset function is activated.
Print only alarm status
When a printer has been connected to the gateway the alarms arising will be printed by it. Here
you can select whether all alarms are to be printed, or whether you want to opt out alarms with a
special status.
Alarm
The function is used for defining handling of alarms in the AKA gateway
All controllers that are or will be connected to this network will be subject to the settings in this picture.
The picture contains five functions that are all transmitted to the gateway when “OK” is clicked. In
order not to disturb new alarms that are only caused by the operation of the menu, the five settings should be considered very carefully.
The five functions are the following:
1. Delete alarm list in gateway (“Clear AKA alarm list”)
The gateway contains an alarm list with up to 250 alarms. This list can be reset by selecting the field.
2. Delaying communication alarms
Here you can delay a communication alarm by up to 240 minutes. The function is only possible in
gateways with software version 5.1 or later.
3. Force disconnect on Alarm
If you require shutdown of an active connection to allow an active alarm to be transmitted to
another destination, mark the field with a tick.
4. Setting of two menus in AKC controllers (“Auto setup”)
If “Auto setup” is selected in pos. “Enable”, the gateway will set the following values in all connected AKC controllers on the network:
- The AKC menu “System address” will be filled in with the network’s own number and with the AKC
controller’s own number
AKM Manual RI0XBh02 © Danfoss 11-2010
71
- The AKC menu “Alarm report to” will be filled in with the gateway’s own system address
When this setting is selected, the master gateway will also carry out the mentioned settings
each time it is switched on.
If “Auto setup” is selected in pos. “No setup”, the gateway will not change the setting of the AKC
controllers. A change can only be made on each individual AKC controller.
During service the setting must always be put in pos. “No setup”! - Remember to change back
the setting when the service has been completed.
If “Auto setup” is selected in pos. “Disable”, the “System address” and “Alarm report to” settings in
the AKC controllers will be removed.
Note! This function can only be carried out, if the connected gateway is the network’s master.
Consequences
When the menu picture is abandoned, it can be done with one of the earlier mentioned settings.
Depending on the selected setting, the following will apply:
“Enable” has been selected! Here the alarms will immediately be released for transmission when a new
controller is connected to the system or there has been a power failure.
“No setup” has been selected! Here the AKC controllers will retain their alarm setting after a power
failure. With this setting, alarms in newly connected units will not be released for transmis­sion.
About two minutes after the selection of one of the routines “Enable” or “Disable” and a click on “OK”,
the programme will be released again, and you may now select “No setup”. Finish by click “OK”.
5. Retransmit alarms (“AKA alarm report to”)
General
The gateway receives alarms from defined units and stores them in the alarm list. In addition
to being stored in an alarm list, a received alarm can also be sent on to an indicated address. A
retransmitted alarm will also appear in the receiver gateway’s alarm list, to which it is addressed. All
alarms are sent on, and if the gateway’s alarm relay is to be used, alarms with status 1 will activate it
(software-based, see Appendix C).
As the alarm list can only contain 250 alarms, the oldest alarms will no longer be registered.
If the gateway is set to retransmit alarms, there may be problems if the receiver is not able to
receive them or acknowledge receipt of them. As the gateway’s alarm list only contains 250 unacknowledged alarms, new alarms, over and above the 250, will not be registered (the most recent
alarm will be "Alarm list overflow").
“None”
If the “None” setting is used, the alarm will only be found in the alarm list.
“System address”
With the “System address” setting, the alarm will be retrans­mitted to the set address.
If the network address is set at 000:000 or NNN:125, the alarm message will be transmitted to the
printer that is directly connected to the gateway.
"AKA alarm schedule"
With the “AKA alarm schedule” setting the gateway will be able to route alarms to different receivers
on its own. The routing will depend on the time schedule that has been entered. The time schedule
is entered by click “Setup”.
72
Manual RI0XBh02 © Danfoss 11-2010
AKM
The receiver of alarms is defined as
primary receiver (“Pri­mary”). If the system
cannot get in touch with this receiver, the
alarm will be sent to an alternative receiver
(“Alternative”), if one has been indicated.
Whenever there is an alarm, information
is also sent to the address indicated in the
“Copy” field.
There is a DO relay output on the master
gateway that can be configured for alarm
reporting (factory setting = DO 2). If this
relay is to be activated in connection
with important alarms (status = 1), field
“DO” must be selected. (The importance
of the alarms is set in every AKC controller. This can only be done via the menu
”Controllers”-”Alarm destinations”).
A change between the two destinations “Default” and “Optional” can be made in two ways:
1) Manual change
Activation of the master gateway’s input DI (that has been configured for manual change-over,
factory setting = DI 2) will produce the effect that “Optional destinations” will be used.
The “Manual” field will show the status of the DI input. A cross in it will show that the function is
active.
2) Time-based change (gateway-time)
By means of the “Start” and “Stop” fields you define the times when “Optional destinations” are
to be used. When the times have been defined, click “Add”, and the time interval will be shown.
Repeat the procedure until all times have been defined.
Please note the required setting for the night between Sunday and Monday.
If an interval has to be changed, select the line, change the time, and finish by click “Change”.
If a line is to be deleted, select the line and click “Delete”.
When the setup has been completed, click “OK”, and in the next picture you have to define the
type of the various alarm recipients.
Note!
If you set the function in
such a way that a master
gateway transmitting
alarms to a printer on
another gateway or relay
output configured for alarm
reporting will not be activated on that gateway.
Here you see the different destinations and their type.
Alarm: The receiver here is an AKM or the alarm-handling function of a master gateway.
AKA gateway printer: The receiver here is the printer connected to the relevant gateway.
Unknown: - the receiver is a gateway and no printer has been connected to it
- if it is an AKM unit which has not been installed
- AKM is not known in all gateway router lines
- AKM is unable to identify the type
If the message “Unknown” is displayed, the setting must be changed to a correct
type.
Click “OK” to approve the setup.
The selected settings are sent to the gateway when “OK” is clicked in the first alarm receiver display
(AKA alarm receiver).
AKM Manual RI0XBh02 © Danfoss 11-2010
73
Password
The password function in the master gateway can be set here.
Factory-set access codes:
Extended access code = 40. This will give access up to and
including the menu section “TIME SETTINGS”.
Service access code = 99. This will give you access to the whole
unit.
In connection with a new setup where there is no password in the gateway, a "blank field" will be the
required setting.
If the password has to be removed from the gateway again, the new password will likewise be a "blank
field".
Events
Here you can display the date, time and system address of the last setting made on the basic setup.
Com.Log.
Here you see the date, hour and system address of the communications made to and from the gateway.
Print
When you click the button “Print” in the “AKA Gateway Setup”, a list will be printed of the various
settings made for the functions in question - RTC, Router, Port; and Alarm.
The function will provide you with a complete list of the settings and may for instance be used for
technical support.

AKM
Control function
You can use this function if you require that the AKM programme is to provide master control of the
following functions:
- Injection on
- Alarm Limit offset
- Alarm limit
- Central Defrost
- Day/Night control
- Suction pressure optimization
- Yearly time schedule
These functions are described in Appendix N.
Principle
The following display will be the first one you encounter when you have selected “AKA control
function” and have chosen the network on which you are going to perform the settings.
- The network number will be seen at the top left. The address will always be 125 as the function is only
present in the network’s master gateway.
- On the left-hand side you can see how much of the space available for definition of override
functions you have used.
Examples of override functions are shown on the display.
Configuration
1. When you want to configure a new override function, press “New”.
2. Now select one of the functions shown in the subsequent display.
If the function is not shown in the

in the system. If there are major
differences between the contents
of a 24-hour display and the weekly
display, this should be examined
more closely.
Change:If you want to make changes in an
override function, you will have to
stop it first.
Delete: If you wish to delete an override
function, you will have to stop it
first. When you are deleting an
override function used by other
override functions, you will receive
an alarm message:
No matter how you continue, you
will not break the configuration
between the two functions.
- With “Stop” you will interrupt

Alarm list
This function shows the alarms that are sent to the system unit on the network.
Select a network.
Only gateways defined as masters can be selected, i.e. address = ✸:125).
After selection, the following picture appears where all data will now be obtained from the gateway.
The picture contains all alarms that have been sent to the gateway (but max. 250).
The alarms received are shown in a sequence where the time (gateway-time) of the onset of the alarm
is the sorting criterion, and the most recent alarm is shown at the top.
A received alarm is shown with its:
- Address
- Address text
- Alarm text
- Alarm time and
- Alarm status (active/not active. Active alarm status ≥1).
When “Print” is activated, a printout will be made of the alarm list shown.
“Alarm number” indicates the number of alarms obtained from the gateway in question.
If new alarms appear when the menu display is on, they will not be shown in the accessed alarm list.
When the alarm list is full (250 alarms), the “Alarm number” field will indicate if new alarms have been

Alarm List
Alarm List
This function provides access to the alarm list in AK-SC 255.
AKM will read the updated list each time the Alarm list function is enabled as well as each time an action is performed in the alarm list display.
If AK-SC 255 is set to route alarms to AKM, the alarm list in AKM will always be updated with the list in
AK-SC 255.
There are three groupings in the display:
• Active alarms
• Acknowledged alarms
• Cleared alarms
Here are the different alarm actions. There are three groups
1. Actions 1-8: Here all alarms, active and cancelled, must be confirmed manually.
2. Actions 9-11: Active alarms must be confirmed manually. Cancelled alarms are confirmed automatically, but only if the active alarm has been previously confirmed.
3. Actions 12-15: Automatic confirmation of both active and cancelled alarms.
If AKM is to resend the current alarm situation in AK-SC 255, the alarms must be selected in
group 3 (e.g. action 12).

Appendix
C: Version history for AKM
Controllers and gateways are made in several software versions.
The earlier versions of the units were designed before the AKM
programme, as a result, the programme cannot communicate
with them.
The AKM programme can communicate with all controllers in the
programme that have been made after the middle of 1992.
AKM version:
2.00 This version and later versions can communicate with the
AKM programme. The DO2 alarm relay in AKA 24 is activated by all alarm types. Alarms can be received from AKC
31M.
2.10
AKA 24’s alarm relay DO2 is activated by status 1 AKC
alarms and "Integrity scan alarms" of status 0 (important
alarms). Selected functions can be set and read in AKC
31M. Alarms can be received from AKC 31M.
2.20
AKA 24’s alarm relay DO2 is activated by status 1 AKC
alarms and "Communication error (DANBUSS)" (important
alarms).
Selected functions can be set and read in AKC 31M.
Alarms can be received from AKC 31M.
AKA 24 can carry out alarm routing on its own.
With AKA 24 it is possible to delete the system address (in
AK 10 and AK 20 units) and the “Alarm report to” address in
AKC controllers.
3.00
4.00
This version contains a log function which can collect and
store data in the master gateway. In addition to this function a “Call back” function has furthermore been introduced, so that the gateway can call an AKM programme to
deliver log data.
The functions can only be operated via AKM.
The introduction of a password function, more router lines
in the modem gateway and an event log reflects the most
important changes.
These changes have resulted in the addition of new code
numbers and a changed type designation. (A "P" and an
"M" have been added to the existing type designation for
the PC gateway and modem gateway, respectively).
5.30
Support for Ethernet introduced.
5.5
P0 optimizing
5.56
Automatic log export
5.64
Support for AK2 alarms via modem.
Support for several network cards.
5.70
Support for AK2 logs and alarms from AK2 plant (modem
and winsock).
Address structure extended for AK2 plant.
Implemented DSN structure (domain, subnet, network).
Implemented new plant archive.
6.00
AKM ported to 32 bit.
Data base change to MySQL.
Prepared AK2 log support.
6.03 Error correction and performance improvements.
6.25
Support for AK-SC 255.
6.26 Support for AK-CS.
Automatic export of AK-SC and AK-CS log files.
6.28 Alarm synchronisation between AK-SC 255 and AKM.
Optimised log and MIMIC performance.
7.00 Windows 7 support.
Language updated.
Scan for AK-SC, CS and SM
Automatic log export of AK-SM log files
Service via alarm list
Modified menu structure
In 1998 AKA 24 is taken out and replaced by AKA 244.
5.00
At your option AKA 244 may be used as either modem
gateway or PC gateway. It contains override function, version 1.
5.10
Connections DI and DO can be configured.
AKA 243 is introduced. The first 60 addresses here have
been reserved for LON data communication (EKC connections).
5.20
The override function is extended to version 2 (defrost
control and day/night control).

Appendix
D: Vocabulary
The programme contains the following terms:
Description file
File indicating the functions a given controller can perform.
Default file
Description file containing factory-set texts, values, etc.
Custom file
Description file which contains customer-adapted selections of:
- Custom text
- Controller user level
- functions to be presented in the plant overview menu
- alarm priorities (of significance to the alarm routing via the AKM
programme)
ID code
A name to which a given address can be added. In other words,
one address may be supplemented with an easy-to-recognise text,
like “frost 1”, another with “frost 2”, etc.
Alarm priority
In the AKM programme an alarm priority can be attached to each
individual alarm from an AKC controller. When alarms are routed
via the AKM programme, the different priorities can consequently
be routed to different receivers.
DSN address
A system address / DSN-address is build up in 4 levels:
aa = Domain (0-64)
bbb = Subnet (0-255)
ccc = Network (0-255)
dddd = address (0-1023), Gateway=0125, AK-SC 255, AK-CS and
System manager=1001
Example of an address 12.010.255.0125

Appendix
E: Log function
Definitions
A log is a serie of data that can be read and collected in the
different controllers for later use. The data can be measured
values from various sensors, or status values for other functions
available to controllers in the ADAP-KOOL® Refrigeration Control
System. A precondition is however that the different values can be
read via the data communication.
Various kinds of data collection can be carried out, depending on
the purpose of the collection. The different kinds of collection are
described below:
1) Trend log
This type of collection is used for adjustments and for trouble
shooting. Via the trend function you select the parameters to
be registered. The AKM programme will now constantly be in
contact with the relevant controller, and a constant and quick
collection of data will be carried out, the sole purpose of which
is to follow the selected parameters. The AKM programme is
now 100% busy with this data collection, and it can be used
for nothing else during this period.
Data can max. be collected for eight parameters at a time.
2) AKM service log
This type of collection is used, when data are collected from
one network at a time over a long period of time. When this
function is used, the AKM programme should be directly connected to the network from which log data are required.
The function can also collect log data from one network via
a telephone connection, but on account of the telephone
costs it is recommended that one of the following collection
methods be used.
3) AKA Service log
This type of data collection is used on networks where an AKM
programme is not constantly connected. The collected data
are stored in the gateway which will then constantly write new
data over the oldest data. If there are problems with the system, the last collected data can then be transferred to an AKM
programme and analyzed (e.g. via a telephone connection). If
a data collection is required which is longer than the one indicated in the “AKA per.” field, the collected data may be transferred to an AKM programme. Define automatic collection in
the AKM programme which will then at intervals contact the
gateway and pick up the collected data.
4) AKA Food safety log/HACCP
This type of data collection is used on networks where an
AKM programme is not constantly connected. The network
is however contacted at least once a day, when the collected
data are transferred.
Data collections can be performed with as little as 15 minutes
between each measurement. The collected data are stored in
the gateway and can at defined times be entered into an AKM
programme, e.g. via a telephone connection.
AKM Procedure
AKA and AKM collections
The log definition must be made in the following way:
- decide whether data collection shall take place from the AKM
programme or from the master gateway.
- select the relevant controller,
- select the parameters applying to this controller,
When these steps are complete, the collection parameters for
log no. “1” have been defined.
- Enter a name for the Log-collection, and how often values are to
be collected (e.g. at 15-minute intervals).
- If it is a “Food safety” log in a gateway, the “Food safety” field
must be selected.
- Established parameters are now ready for registration in the log.
Since only relevant collected data are to be presented later, the
period for which those values are to be stored in the log must
also be defined. When the collected data become older than the
defined period they are automatically deleted.
- All definitions have now been made, but data will only be
collected from the time the log is started.
When this procedure has been completed for one controller, it
must be repeated for the other controllers - until all required logs
have been defined and started. (The AKM program contains a
function able to “copy” a log for a given controller, but only when
data are to be collected from a corresponding controller with
the same software version. And copying can only be carried out
within the same network.).
AK-SM collections
The log definition must be made with the service tool AK-ST 500.
AK-SC collections
The log definition must be made with the AKA 65 software program, or directly on the front panel.
AK-CS collections
The log definition must be made via a web browser or directly on
the front panel.
Display
When the various logs have been defined and data has been
collected over a period, the values can be displayed in graph
form on the PC screen, or printed out. A printout in table form
is also possible, or the values can be transferred (export) to a
spreadsheet for further processing.
To enable a simple graph for a number of parameters from
different controllers to be made up, the parameters from different
logs (different controllers) can be extracted and stored under one
name. The selected parameters can then be shown in the same
graph display/table printout. For example, data from sensors that
register the temperature of the medium at different refrigerated
counters can be collected under one name and then be shown in
one display.
Manual RI0XBh02 © Danfoss 11-2010

Appendix E - continued
Deletion of collected data values
The period for which collected data are to be available must be
defined in the AKM programme. Data older than the defined
period are automatically deleted. The deletion occurs at fixed
times defined in the program. These times cannot be altered.
When such deletion is performed it is displayed in the form of an
icon with the text “Delete logs”.
Limitations
Common:
- Data for a maximum of 13 parameters can be collected in each
log (13 registrations from each controller).
- Collected data will not be stored satisfactorily when collection is
defined by a long interval and a short period, e.g. a log interval
of 4 hours and a period of 1 hour.
AKA logs:
- Max. 170 logs can be defined in AKA logs (120 food safety logs
and 50 service logs). Data can be collected from all of them
simultaneously.
- The interval for “Food safety logs” cannot be less than 15 minutes.
AKM logs:
- Only data from one network at a time can be collected.
- Max. 999 logs can be defined in an AKM service log, but data can
only be collected from 120 logs at a time.
- Data from max. 20 logs can be collected, if just one of the logs
has been set with a time interval of one minute. (45 logs if two
minutes, 70 logs if three minutes, 90 logs if four minutes, and
120 logs if five minutes).
- If data are collected from 25 controllers and the log intervals
are 30 minutes, a new log with time intervals smaller than two
minutes cannot be started.
- If short log intervals are used, the AKM program should not be
used for anything other than logging.
Collection procedure
Data are collected at fixed times in accordance with the time
interval. All logs having the same time interval are collected
during a period within the duration of the interval and a
presentation of these data will contain this fixed time (even when
the collection of many data for many logs extends over several
minutes).
A log starting point is not synonymous with the time of the first
data collection. The first data collection is determined by internal
program parameters and occurs before the stated time interval
has elapsed (e.g. if a time interval of 1 hour has been defined, the
first data collection will occur after a maximum of 59 minutes).
Subsequent data collections will then occur at the defined time
interval.
When at least one log has been started, this will be indicated by
the “AKM Log” or “AKA Log” icons at the bottom of the screen.
Whenever data are stored on the PC’s hard disk, this can be seen
from the icon (a connection between the units is shown).
Newly collected data can at any time be stored manually on the
hard disk. Activate the icon and start the function storing log data.
98
There are four different types of logs:
- Trend logs
Data are only collected when the AKM programme is in direct
contact with a controller.
- AKM service logs
Data are collected directly for a started AKM programme. The
collected data are subsequently stored on the PC’s hard disk.
Data can only be collected when the PC is on and the AKM
programme has been started. If the PC is 100% busy with something else (e.g. a time-consuming printout), you cannot be sure
that all data will be collected during this period.
- AKA Service log
Data are collected for service information. The function constantly collects data in the master gateway. New data are all the
time written over the oldest data. The registered data will only
be called, if there are problems with the system.
- Food safety logs
This type refers to data collection for registered food tempera­
tures. The function constantly collects data in the master
gateway. The collected data are then transferred periodically
when "Auto. collect" is defined (or more often, if required by the
master gateway’s memory) to an AKM programme log database.
Collected data can be transferred in one of the following two
ways:
1) The AKM programme contacts gateway and picks up the data.
2) The “Call back” function is selected in the AKM setup. (Callback
is only actual for AK-SC, CS and SM if they are connected to a
modem). The following will then happen:
- The AKM programme contacts gateway and asks it to establish contact in one minute.
- The contact is interrupted.
- One minute later gateway will contact the AKM programme
and the data will be delivered.
If the gateway has not established contact within 15 minutes,
the AKM programme will once more establish contact to the
gateway, and the data will be picked up right away.
If an AKM programme has to pick up collected data from several
master gateways, there will be a pause between the individual
collections. The pause will be between 0 and 5 minutes long (1 to
6 minutes when the “Call back” function is used).
The time used for collecting data will vary depending on the
number of logs to be collected and the amount of data contained
in the individual logs, and whether the connection is via a modem
or TCP/IP.
Generally:
- A few logs with many data can be collected faster than many
logs with a few data.
- It will take longer if the data are transmitted via several DANBUSS networks.
Example:
- Data are obtained over the telephone network via two master
gateways.
- 65 logs will be collected (10 Service logs and 55 Food Safety
logs).
- Gateway’s memory is full (80% of max. and must be emptied).
This data transmission will take between 20 and 25 minutes,
depending on the hard disk’s performance and the database
contents.

Collected data are stored in the PC memory (RAM), until the
amount of data is large enough to be transferred to the hard disk.
When the transfer is made, an icon “Move logs” is displayed.
In addition, data are stored on the hard disk when the log
definition is changed, or if the manual function “Save logs” is
activated (started by activating the icon “AKM Logs”).

Error messages
Error messages in connection with log definitions and log collec­
tion.
If the log function is operated incorrectly, there may be alarm
messages. These alarm messages will mostly occur, when logs
from another AKM programme than the one installed in the system are established or changed (e.g. in connection with service).
Alarm messages will also occur when controllers are exchanged in
the system and the controllers in question are collecting log data.
Typical sources of error:
- Name or disc period has been changed.
- Logo type has been changed (e.g. a food safety log has been
deleted and a new service log with the same log number and
setup has been established).
- Logging is carried out from another AKC address than the original one (e.g. a log setup is deleted and then re­-established in
connection with another AKC address).
- Logging is performed with other parameters than originally.
- A log has been deleted or added.
- Clock in the gateway not correctly set
- Too little space on the PC hard disc

Corrections
If you wish to use the log setup in the master gateway:
- Click “Yes” in the previous display.
Data can now be obtained either by means of automatic
collection or manual collection.
If you wish to use the log setup in the AKM programme:
- Perform an “Upload” of the network configuration and of the
description files.
- Carry out manual collection of the active logs.
- Send the AKM programme’s AKA-log setup to the master
gateway by using the “Restore” function. The function is
primarily used, when a master gateway is exchanged. Only if
the log setup of the AKM programme is completely identical
with the system, to which the “Restore” is addressed, will the
entire log setup be delivered to the master gateway.
If the error is due to an exchange of AKC controllers:
- Perform an “Upload” of the network configuration and of the
description files.
- Make corrections in the defined log (remove parameters
shown as “Unknown”).
- Click “OK” to store the log setup.

Repeat routine
If a log collection cannot be picked up/delivered to the defined
receiver for one reason or another, a repeat routine will be started.
The routine will repeatedly try to establish the connec­tion. If it
fails, a system alarm will be released (this system alarm will also be
entered in the “AKM Event log”). Appendix F contains a description
of the repeat routine.
Note!
If there is less than 1MB space left on the hard disc, the log
collection will be stopped. If this happens, a system alarm will
be given and the log icons will be marked with a cross.

When retrieving an AKM service log, the AKM program establishes
a connection to the master of the required network. If contact cannot be established, attempts are made every 7½ minutes. When
contact has been established to the master, AKM will ask for value
in the controller. If this value is not received as mentioned under
“General Communication”, an error report will be issued. A new
attempt will be made after:
- 5 times the log interval for log intervals under 5 minutes
- 2 times the log interval for log intervals between 5 and 15
minutes
- 1 time the log interval for log intervals over 15 minutes
When a data collection has to be obtained from a master gateway,
the AKM programme will establish a connection to the master
gateway.
If the “Call-back” function is used, this function will be established,
and the connection will be interrupted. The master gateway will
then reestablish the connection a little later. If this connection is
not established within 15 minutes, the AKM programme will again
establish a connection and immediately start the collection.

another attempt will be made.

Appendix
G: Custom texts
The programme can use text in several languages. They have
been defined on the basis of the following assumptions:
- Used language version of the Windows programme.
All functions with text controlled by Windows (primarily messages) will use the text from Windows.
- The various AKM program displays contain text in 18 languages.
The menu “AKM setup” shows which languages are available.
Selection can be made between the languages displayed.
If the language must be changed after installation, the newlychosen language will not apply until the AKM program has
been restarted.
- Custom text may be entered together with the controllers' menu
text.
The menu text of the different controllers are written in English.
(Some of them also in other languages). This text will be used in
the programme, if nothing to the contrary is done. However, if
you require a language/system defined text, it is possible to enter this text together with the text, obtained from the controller.
On the actual displays it will now be possible to choose between two languages:
(Default = the language obtained from the controller, or custom - the text that has been entered).
Entry of a language-defined text is performed with the ”Edit
custom file” menu.

AKM
Appendix
J: Customer-adapted description files
(Also called custom files)
This is how the AKM Programme uses description files.
The basis of a description file will always be the data found in
a controller. In some controllers there are more sets of data to
choose between, depending on the number of language versions
the controller has been provided with.
When the AKM Programme has to obtain data from a given
controller, it will only obtain data belonging to one language
version. A setting in the controller will determine which language
has been selected, and hence the data that can be picked up by
the AKM Programme.
When the data communication is ready, data can be obtained for
the AKM Programme with the “Upload” function. When this has
been done, the AKM Programme has a “Default Description file”
and can now communicate with controllers of this type.
There are however advantages in processing a “standard
description file”, so that it becomes a “customer-adapted
description file”:
1. Texts
Each function has a set of texts that are obtained from the
controller (Default). The texts will always be present in the file,
and they cannot be changed.
These texts can now be supplemented with a customerdefined text. This is done by adding a specific text opposite
each standard text (or opposite the most used functions).
When this editing has been concluded, this text will be called
“Custom”.
When the AKM Programme is used there will then be screen
displays where you may choose between “Default” and
“Custom”.
2. Plant overviews
All functions, measurements and settings etc. can in principle
be shown in a plant overview, but to obtain the best overview,
only a selection of data should be displayed. This selection is
performed here in the description file. Opposite each function
you would like shown in a plant overview, you must indicate
that it must be used in the plant overview. And it is only the
marked functions you will later be able to choose between.
Select, for example, relevant temperature measurements,
temperature settings and defrost functions.
AKM 3. User levels
The individual users of the AKM Programme are assigned a
user level when a user is established. Here you may choose
between three levels - low, medium or high. In the description
file the various function groups may also be assigned a corre­
sponding function. In this way users with “Low” status will
only have access to functions with “Low” status. Users with
“Medium” status will have access to low and medium-level
functions. Finally, users with “High” status will have access to all
the functions.
4. Alarm routing
The AKM Programme also contains a function which can route
alarms to various receivers at different times - and they can be
routed according to priority.
If this alarm routing function is to be used, it is here in the
description file that the priority of the various alarms has to be
defined. And this priority will only have an influence on how
the alarm is routed in the "AKM Alarm Schedule" func­tion.
When the editing of a description file has been completed, the file
has to be saved. This can be arranged in two ways:
a) It can be saved as a new default file where the edited file is
entered and replaces the standard file obtained from the
controller.
b) It can be saved as a separate file.
If this solution is chosen, the file must be given a name and
subsequently linked to the relevant controller in the “Upload”
display. If there are several controllers of the same type and
with the same software version, the same file may also be
attached to these.
Once a description file of one type or another has been edited, the
file may be used in another system.
- Use the “Export function” for copying the file on a USB key.
- Then use the “Import function” for copying the file into the new
system. (If the description file is saved as a “New Default”
and imported before the “Upload” function is started, no
data or languages will be obtained from the controller).

Selection of printing
Before starting with this appendix you must have installed
the programme and obtained all the controller data from the
individual controllers. This process has been described in an
earlier document “Installation guide”, and it is a condition for
the continued procedure that this has been done.
You now have two options:
Either
1 Imported description file
Have you imported customer-adapted default files? (I.e.
custom files that have been edited in an earlier installation and
subsequently stored by means of the function “Save As Default
file”. This file may be imported before upload is carried out
(Upload configuration) and will then replace the default file
uploaded from the controller).
If you have imported such default files prior to uploading, and
editing is not required in these files, continue on the next page.
However, if editing has to be done in some of the files, continue
with the procedure shown below.
Or
2 Upload
You have asked the programme itself to upload the various
default files from the controllers by means of an upload (Upload
configuration).
If this is the case, you must now open the individual files and add
a customer-specific adaptation.
Procedure:
- The existing default file is opened
- The text is adapted to the plant, and para­meters for presentation are selected
- You may now save the file under a new name which you decide yourself
- If the same texts can be used in several controllers of the same
type, it is enough to adapt one file. The relevant control­lers can
then share this file. But if different texts are required for the in­
dividual controllers, you must adapt a file for each controller
The whole procedure is described in the section “Edit Custom
file” . Study that section and proceed on the next page.

Set clock function in the master gateway
Description
There is a clock function in the master gateway. This clock
function is used for time setting alarms, collection of data and
synchronisation of the clock functions in all the other controllers
on the network.
The clock in the master gateway can be set with this function.
Procedure
In the “Setup” menu, select “Advanced Configura­tion” → “AKA Real
Time Clock”.
Select master gateway (address = xxx.125)
If there are several networks, repeat the fol­lowing for each network.
Summer/winter time
The gateway can itself change the clock setting in the controllers
when there is change-over from winter time to summer time and
vice versa.
The programme will now read the clock setting in the gateway.
This setting can subsequently be seen in the “Real Time Clock”
field.
If the time is not correct, you may key in the correct time. You may
also transfer the PC’s clock setting to the gateway by click “PC time
→ RTC”. (The times shown will not be transmitted to the gateway
until you click “OK”).
106
Define whether change-over to summer time is required with the
settings:
- OFF
No change-over to summer time
- Manual
Changes are made here of the days and times which
you yourself have to enter in the two relevant fields
- Auto
The gateway itself sets the days to:
- last Sunday in March and the last Sunday in October

Establish a user
Description
Before you proceed with the programme setup you must establish
a user of the programme. And it is best to establish the user who is
to have the highest authorization, i.e. who will be operating most
functions in the programme. All other users may be established at
a later date.
Procedure
1) In the “Setup” menu, select “Authoriza­tion”.
2)
b) Select user level for operation of AKC controllers. The user
levels for various functions have been defined in custom file.
These user levels can now be used, so that important functions are kept invisible to the users who are not authorized
to use them
At this point, when you establish the user, you decide how
many func­tions the new user may use when he/she is to
operate the system at a later date. E.g. whether a tempera­
ture may be set, or whether it may only be read.
- “Low” is defined for users who are only allowed to operate a
few functions.
- ”Medium” is defined for users who have access to almost all
functions
- ”High” is defined for users (e.g. service engineers) who
in addition to all the other settings also have to set
functions requiring special knowledge.
c) Functions
Click "New".
3)
Enter initials of the new user and click “OK”.
(Be aware of capital letters and small letters).
4)
Here you select all the functions the user may operate.
5) Click “Save” to save the new user authorization.
a. Name and Password.
Enter name and password of the new user (the user may
then personally change the password later).

Assign a name to plants, appliances and rooms (only possible for AKA)
Description
To facilitate daily operation you may give the various controllers
a ID-name. Based on this name it will be easier to operate the
different settings than if the controller was only defi­ned with a
system address.
Procedure
1) First check which controllers have been obtained for the programme.
In the “Setup” menu, select “Upload”.
Now enter the net­work number and click “OK”. E.g.:
MCB:
Here you can read
if the controller
has an “AKA
override function”
and on which
level.
2) Now set the “ID-code” fields.
This is where the individual controllers are as­signed a name of
your own choice. It may be a name based on what the section
is referred to in everyday parlance, e.g. fru­it, vegetable or milk.
3) Select a controller (a line) and click “ID-code”.
4) Enter the required name and click “OK”.
5) Repeat points 3 and 4 until all control­lers have been given a
name. (Address number 125 is master for all the other controllers, and the name here may for instance be the shop’s name).
Example of final result.

Appendix K - continued
Now that all individual controllers have been assigned a name, the
individual controller must also know which texts and functions
have been customer-specified for this controller. And here is
another either-or situation for you:
- If you said Yes to point 1 on the appendix' first page where you
had already imported customer-adapted files, you may skip the
rest of this page and continue on the next page.
- If you said Yes to point 2 on the appendix' first page and have
moved to the end of the instructions to edit Custom files, you
must now attach these Custom files to the controllers (a Custom
file may be used by several con­trollers, if the controllers are of
the same type). Proceed below.
1. Continue from the previous display:
2. Select controller to which file is to be attached.
3. Then click “Custom”.
Now all files of the same format as the selected controller will be
shown.
4. Select the file that is relevant for the selected controller and
click “OK”.
5. Repeat points 1 to 3 for all controllers to which files are to be
attached.
6. Finish with “OK” and continue on the next page.
Note. If you regret the text in the selected file, you may reselect
the factory-set texts by se­lec­ting “Default” under point 2 and
using the file with the controller’s code number.
But if a file is used which has been “Save As Default file”, it will be
necessary to delete this file and carry out a new upload from the
con­troller in question.

How to define a plant overview
Description
A plant overview is a display showing selected measuring values
or other relevant situations for the plant. It may for instance be the
temperature at the various refrigeration points, whether defrost
cycles have started, or whether there are alarms of a certain type.
You must now define this overview, and you can define it in such a
way that the overview is depicted either as a drawing of the shop,
bar chart or as a number of lines with current values
To obtain "a drawing of the shop", you must have AK-Mimic or
AKM 5. This is discussed in Appendix - AK-Mimic. When you have
studied the AK-MIMIC document, go on to the next section entitled "How to define measuring points for logs".
If you want a "column diagram“ or "lines with actual values“,
continue here.
You may also define additional overviews, so that one display for
instance shows tempera­tures, another defrosts, a third settings,
etc.
If the plant is a small one, all these things may be shown in one
overview, but that will re­quire that max. 50 displays be selected, as
that is the limit for one overview.
Procedure
1) In the “Setup” menu, select “Setup Plant overview” - "Plant lists".
All controllers on this network are now shown for the selected
system.
a. Start by defining name and title on the list.
b. Then select the text to be shown for the controllers.
-Select “Default”, if the ori­ginal text in the controllers is to be
used.
- Select “Custom”, if a number of user-defined texts are to be
used.
c. Now select a controller, and after that the measurement or
function to be displayed.
2) Click “New”
- If the programme knows several net­works, a display will
appear where you have to select a network. Do that and
proceed to point 3.
- If the programme only knows one network, it will automatically move on to the next display.
3) From this display you may now establish one or more plant
overviews:
110
Shown to the right are the measure­ments and functions
you may choose between. If a tick has been placed in the
“Parameters used in all func.” field, an additional number
of selected para­meters will be shown from the con­troller
in question. These parame­ters were not defined when the
user-defined description file was set up, but are determined
by the controller type. Select also one or more of these
parameters, if required.
d. The various measurements and func­tions are selected by
click “Add”.
Manual RI0XBh02 © Danfoss 11-2010
AKM
Appendix K - continued
The measurements selected for the overview are shown in
the middle of the display. You may select as many as 50. (In
the plant overview they may subsequently be shown as 50
columns or as 20 lines).
Useful hints
If another sequence is required for the selected lines, you
may move lines or insert new lines, as fol­lows:
1) Select a line
2) Click the right-hand mouse key
3) Move the cursor to the place where the line is required
4) Click the right-hand mouse key once more
Select one or more lines that are to have the same colour,
and click “Color”. Now the display will appear where colours
can be selec­ted. Select colour and click “OK”.
(You may for example select light blue for refrigeration
temperatures, dark blue for freezing temperatures, and red
for temperature alarms).
The chosen colour will now be placed on the lines selected
on the pre­vious display.
f. Activate “Save” to save the overview.
4) A plant overview has now been defined.
e. Select colour for display of columns
Repeat point 3 until all plant lists have been defined on this
network.
5) Autostart
A plant overview can be defined for auto­start. This means
that the selected overview will be shown directly after log-on
when the programme is started. You may choose autostart
for one overview by selecting it and subsequently click “On”
under auto­start. A cross at the right-hand side of the line now
indicates that it has been set for autostart.
6) If there are several networks, the whole section is repeated for
each network.

How to define measuring points for logs from AKA
Unfortunately, logs cannot be set up from AK-Monitor. Instead,
use AKM 4 or AKM 5 for this.
Description
Types
Two types of logs can be defined. In principle it does not matter
which type is selected, but the decisive thing is whether the PC is
switched off for periods of time, or whether the AKM programme
is stopped. If that is the case, select the type where data collection
takes place in the master gateway.
2) Proceed from this display, if AKM Service logs has been defined
- Collection of data in the PC (AKM Service log)
“AKM_Service_logs”. It is a require­ment that the PC is switched
on and in constant touch with all the controllers. Neither the
AKM programme nor the PC, must be stop­ped.
- Collection of data in the master gateway
This type collects data in the master gateway, where the data
are stored for a defined period of time.
All data will at suitable intervals be transferred to the PC (the
programme it­self calculates when transfers are to be made). If
the PC is switched off, for example on the point of transmission,
the programme will start picking up log data about one minute
after the programme has been re-started.
(Please note: If the network contains both a PC gateway and a
modem gateway, the modem gateway should be the master on
the network. In that case the data communica­tion will not be
disturbed unduly when large amounts of data are sent out on
the telephone network).
Click “New”.
3) Select controller
Limitation
Logs are defined for one controller at a time, and there is room
for 13 parameters in one log definition. It is possible to establish
several logs for the same controller. As many as 120 logs can be set
up on each network.
Procedure
1) In the menu "AKA" - "Log Setup" select network
Select the controller from which data are to be uploaded.
4) The log can now be defined.
Indicate where to collect data:
Address xxx:125 is in the master gateway
AKM Service logs is in the PC
112
a. Start by giving the log a name
The ID code is automatically pro­posed, but the name can be
changed, if you wish.

AKM
Appendix K - continued
b. Set the intervals
The time can be set between 1 and 240 minutes. If the field
“Food Safety” is also selected, the time can be set between
15 and 1440 minutes. (See also point d.)
g. The various measurements and func­tions are selected by
click “Add”.
c. Select Disk Per. time
This is the period of time the data have to be stored on the
PC hard disk. They may be stored for up to 800 days for all
types of logs, but the minimum storage time differs and is
determined by the type of log in question.
Important:
When data become older than the set time, they are deleted
(they dis­appear for ever), and they can no longer be displayed
or printed. You must therefore set the time, so that data are
present when you want to have them displayed or printed.
d. The next three points are only vi­sible when a log is established in the master gateway:
1. AKA - per
This is the period of time the data have to be stored in the
gateway. Data can be stored for as long as 250 hours for
service logs, and for as long as 960 hours for Food safety
logs.
Up to 13 parameters can be selected in each log definition.
5. Save this log definition by activating “OK”.
Important:
When data become older than the set time, they are
deleted (they dis­appear for ever), and they can no longer
be displayed or printed. You must therefore set the time,
so that data are present when you want to have them
displayed or printed.
The PC and the programme must there­fore never be
switched off for a period that is longer than the set AKA
period.
2. Selection in Food Safety
When a selection is made in the “Food Safety” field, the
log will be defined as a food safety log. If no selection is
made, the log will be established as an AKA ser­vice log.
3. Used space
Shows in % how much space has been reserved for the
defined logs (one log definition may max. take up 25%).
6. If there are several logs to be defined, point 4 can be repeated.
However, if they are logs for the same type of controller and the
same software version, the succeeding logs may be defined by
means of a copying function.
Select a log and click “Copy”.
e. Now select the type of text to be shown for the controllers.
- Select “Default”, if the ori­ginal text in the controllers is to be
used.
- Select “Custom”, if a number of user-defined texts are to be
used.
f. Now select a function group, and after that the measurement
or func­tion to be logged.
Shown to the right are the parame­ters (measurements and
functions) you may choose between.
AKM a. The earlier log is seen at the top.
b. In the centre field you write the name of the new log, or you
put a tick in the field “Use Id-code as log name”. The general
rule is that if you select one con­troller for this log, the log
must be given a name. But if you select several controllers
for this log, a cross in the ID code field will provide separation of the individual logs.
c. At the bottom you select the con­trollers the new log is to
belong to.
d. Finish by click “OK”.

7. When the different logs have been defined, it is possible to:
- Start and stop
If data has to be collected, the log must first be started. Select
and click “Start”. The word “On” on the line indicates, that data
will be collected.
- Collect data
Before a collection of data can be stored on the PC hard disk,
the data must be obtained from the gateway. This is normally
done automatically. Select the logs to be obtained and click
“Auto Col.”. The word “Collect” on the line now indicates that
the data will be picked up automa­tically at least once a day.
The data can also be obtained manu­ally, e.g. in service situations, where the most recently collected data must also be
included (data collected since the last automatic transfer).
Activate the icon and click “Manual Collect...”
- Make printouts
With a click on “Print” the log’s definitions are printed, i.e. the
parameters collected (several logs may be selected for the
same printing operation).
- Perform editing
Select the relevant log and proceed with “Edit”. The required
changes can now be made (the collection of data must be
stopped, when the log has to be edited).
- Make deletions
If a log has to be removed complete­ly, select it and click
“Delete”. (The log must be stopped, with “Man. Collect.”).

How to define presentation of logs from AKA
Description
In the previous section it was decided which mea­surements and
functions were to be collected. In this section we shall now define
how the col­lec­ted data should be presented when they are later
displayed or printed out.
Unfortunately, logs cannot be set up from AK-Monitor. Instead,
use AKM 4 or AKM 5 for this.
4) All logs in this system will now be shown in the centre field.
The presentation can be in the form of a graph­ical display where
up to 13 random logs are shown in the same picture, and where
all logs in this picture will be from the same network. All collected
values may also be printed out as tables, and all logs from the
different frost rooms may for example be printed on the same list.
And this list may then be defined to be printed at specified times,
e.g. every Tuesday at 10 am
If you define the presentation so that about six logs are shown in
each display, you will make best possible use of the paper when
the data collection is printed. It will also be difficult to take in
several curves when the collection of data is shown graphically.
Procedure
1) In the "AKA" menu, select "Log Setup"
a) Start by entering name and title on the log list.
b) Select Custom in the “AKC text” field. When you do that the
earlier defined texts will be used. (If you select default, the
factory-set texts will be used).
2)
c) Selection of measurements and functions to be presented must be performed in the two bottom fields
Select a function and select a parameter. Now click “Add”.
d) Repeat point c until all the re­quired measurements or functions have been entered in the field at the centre (max. 13
can be selected, but you should not select more than 6).
Click “New”
3) All systems (networks) where logs have been defined will now
be shown.
Hints
If another sequence is required for the selected lines, you
may move lines or insert new lines, as fol­lows:
1) Select a line
2) Click the right-hand mouse key
3) Move the cursor to the place where the line is required
4) Click the right-hand mouse key once more
e) Save the list by click “OK”.
Select the system where the presentation has to be defined
and finish by click “OK”.

the actual definition of the pre­sen­tation of logs has been
completed. Terminate this display by click “Cancel”.
- If the data are to be printed in table form or based on a fixed
time pattern, this can be done automatically:

Appendix
M: Graphical representation of the operating condition in a refrigerating plant
Introduction
AKM is for control and monitoring of refrigerating plant fitted with
an ADAP-KOOL® Refrigeration controls system.
Depending on operating needs, AKM is available in four versions:
• AK-Monitor
• AK-Mimic
• AKM4
• AKM5
A few words about the symbols
Symbols of different kinds will be found here in the user menu - but they will
only be shown when something “happens” in the plant. The symbols have
the following meanings:
-18°C
Temperature:
Shows the temperature at the refrigeration point.
Drops:
Shows that defrost is in progress.
During defrost you must expect that the temperature is a little
higher than during normal operation. If the temperature becomes
too high over a period of time, the alarm will sound.
The defrost symbol will be shown during defrost..
Two of these programs (AK-Mimic and AKM5) can show a display
of a supermarket's cooling sites.
Alarm bell:
Indicates that there is an operational breakdown in the plant. Either
there is a defect, or the temperature lies outside the permitted
value. This situation requires a close examination, the purpose of
which is to identify the defect.
Refrigeration symbol
Shows that there is refrigeration at the site.
Stopped regulation:
The regulation has stopped here, so that the refri­geration point is
not working.
Manual operation:
Regulation has been stopped here and set to manual operation,
so that the individual functions may be controlled by force.
Door:
Indicates that a door is open.
Placed opposite each refrigeration point are names, symbols and
temperatures, so that the operating situation of the plant can be
followed from just one display.
Compressor:
Shows that the compressor is operating. A value indicates how
much capacity has been cut in.
Fan:
Shows that the condenser is operating. A value indicates how
much capacity has been cut in.
Cross:
The stated parameter does not exist in the controller. Check that
the correct object is being used.
Hourglass:
Shows that no data are available at the present time or that the
function is waiting for data from the controller.
Short-cut
A supplementary drawing for the refrigeration point has been
established here, and you can access the drawing on the screen.
Stars
Indicates a sensor error.
Hatched symbols
There is a communication error in the plant.
Question mark
The database is messed up with objects. Check that all objects have
been transferred in connection with imports and exports.
Exclamation mark
There is conflict on the network. Check the network.
Windows flag
One of the above mentioned symbols should have been shown
here, but the programme is unable to locate it.

Principle
1. First make a drawing of the relevant plant.
2. For each refrigeration point a controller has been placed that controls and
monitors the refrigeration point.
3. The drawing is now used as background on the PC-screen, and
the controller’s functions are placed symbolically at the refrigeration point.
-18°C
4. Next to the refrigeration point a number of selected functions
will now be seen which will only be visible under certain
operating conditions. e.g. water drops when a defrost is in
progress.
The symbols shown will depend on the refrigeration point that
is being controlled, and to what attention needs to be drawn.
There may for instance be alarm symbols, temperature display,
open door, and the controller’s operating condition.
So much for the setup part.
AKM User part
In connection with later displays in the user part, all the necessary symbols will now appear under given operating conditions.
With the symbol as the starting point, the user can now move
further into the underlying functions. The following may for
instance be seen:
- temperature performance at the refrigeration point (logs)
- alarms
- changes may be made to previous setups, and temperatures
may be adjusted
- there will be access to all the controller’s functions when
service is required.

Appendix M - continued
Preparation
Before you can start the setup you must have drawn a picture of
the plant to be operated. You may for example have an overview
drawing at your disposal which you can use directly or maybe scan
in, and then have it converted to the required format. It is important, however, that the end result will be a drawing in BMP (BitMaP)
format.
A few more words about preparation
The programme has been designed in such a way that you may
make a setup on a PC without there being a direct contact to the
relevant plant. If you wish to make a setup in this way, read on
below.
Example
No direct contact
When you are about to move a controller to a specific
refrigeration point, you must know which controller and which
software there are at the different addresses, otherwise you will
not be able to carry out this kind of setup.
1. First define the relevant network number of the plant.
2. Then give this network an address.
3. It is now up to you to define the code number and software
version.
4. After this, you may proceed as usual.
In other words:
Without a direct contact the programme cannot know which
control­lers are placed at which addresses. It is up to you to know
all the data.
Hints
When there is direct contact
• Supplied with the MIMIC programme are a couple of recommended systems. Study them on the screen before you start
your own drawing.
• It is best to draw the picture on the screen, on which the picture
is to be used. In that way you avoid problems with screen resolution and drawing size.
• If you make the drawing on another screen, you have to know the
screen resolution to be used to obtain the best results.
Find the resolution to which the system’s screen has been set
and make the drawing based on this setting.
Also use the colour resolution employed by the other screen. If
you are in doubt, choose 256 colours or less.
When you wish to attach a controller to a specific refrigeration
point, the programme will help you with the controllers’ type,
code number and function. The programme will obtain these data
from the upload function.
1. First select the network number.
2. Then the address.
3. The code number and software version will now be displayed.
4. Proceed as usual.
In other words:
When there is a direct contact, the programme will guide you to
the relevant data.
• Installed together with Windows is a programme called Paint.
This is simply a drawing programme that you might like to use.
• When you save the drawing, it may for instance be in 256 colours,
but it must be in format BMP.
• When you have a finished drawing of the plant, you may copy
your file into the folder of other BMP-files. The path could for
example be: C:\AKM\AKLAYOUT\

Construction of objects
The function is an editing function for the controls described in
the “Setup Plant overview” section.
With this function you can edit an already existing object or construct a new object right from scratch. It is however a requirement
that you are familiar with the functions of the controller, so that
you know which information the controller is capable of transmitting and receiving.
Construction of objects is only for super users!
The function can only be operated via programme AKM
5 with software version 5.2. or newer.
A bit about information from the controller
A bit about objects
- Temperature value.
Here you will obtain a value between -30 and +30 from the
controller, and it will be your job to describe what it is and what
name it is to have. E.g. “Defrost sensor” and “°C”.
When you have constructed an object it must subsequently be
placed in the plant overview. How this is done has been described
earlier in the manual.
- Operating conditions
The various functions in a controller will change between certain
operating conditions. These operating conditions will be transmitted as a value and will be:
• 0 or 1 when a relay output is inactive or activated;
• 0, 1, 2 or 3 when there is alarm status;
• 0, 1, ....... or 11 when it is the controller’s actual operating condition. 0 will here represent “no refri­geration at the moment” and
4 may represent “defrost going on just now”.
To make such an operating condition visible, its parameter
value may be linked up with a symbol, and the symbol may for
instance be selected, as follows:
- Parameter for compressor relay: Compressor symbol when the
parameter value is equal to 1.
- Parameter for alarm status: Alarm bell symbol when the parameter value is equal to 1 or 3.
- Parameter for regulating condition: Symbol of a couple of drops
when the parameter value is equal to 4, and of an ice crystal
when the parameter value is equal to 2.
There are two types of objects you can construct:
• Standard object - a simple display of a number of parame­ters
The selected parameters are shown here with texts, measure­
ment values and symbols.
It is this block you subsequently can place in your plant overview, as mentioned earlier.
• Application object - Parameters are displayed together with a
drawing of, say, a refrigeration appliance.
In order to make these setups you must know the parameter
name and the parameter values of each function you wish to
include in the object.
You will find this information in the document “Menu operation”
for the respective controllers - but please remember that the code
number and the software version must be compatible.
(If a parameter value is indicated as ON/OFF, it will be equal to 1 /
0).
In an application object the parameters will be linked up with a
drawing, so that you can place the different parame­ters at the
exact place in the drawing that fits your application.
You must place the application object in the plant overview, as
mentioned earlier. But in contrast to the standard object where
the parameters are shown directly in the plant overview, the
application object will be placed on a short-cut icon. When you
now click on this short-cut icon, you will skip the routine and
obtain the drawing of the refrigeration appliance with belonging
parameters.
In more complicated drawings of, say, a compressor room you
will be able to place many parameters, but you are not allowed
to place more than 26 different parameters. This is what the
programme allows.

Appendix
N: Control function (Overriding) from AKA
Introduction
Definition of control function
Principle
The following display will be the first one you encounter when
you have selected “AKA" - "Control function” and have chosen the
network on which you are going to perform the settings.
- The network number will be seen at the top left. The address will
always be 125 as the function is only present in the network’s
master gateway.
The master gateway of an ADAP-KOOL® refrigerating system
contains an override function that can transmit signals between
selected controllers via the data communication.
Setup takes place via system software type AKM where the
individual functions are established. During the subsequent
operation it is not necessary for the AKM programme to be
operative - the master gateway itself will control the functions.
Based on the selected function the controllers are gathered in
groups. So when there is override, all controllers in the group will
receive the same override signal.
Among the functions can be mentioned:
• When the last compressor is stopped in a system, the compres­
sor control will signal all the controllers to close the valve in the
refrigerating circuit.
• The alarm limits for an entire refrigerating system can be
changed as a function of an outdoor/indoor temperature.
• Defrost start can be carried out centrally
• Change-over between day and night operation can take place
centrally.
• Optimisation of system’s suction pressure
The functions are described on the following pages:

AKM
Appendix N - continued
Injection on
Principle
Automatic
Compressor control
The override function itself reads the parameter showing the AKCON function’s signal.
Controllers with AKV control
The override function will itself find the parameter controlling the
AKV valve. (When there is override, the AKV valve will always be
closed).
All controllers controlling an expansion valve have an AKC ON
connection. By cut out this connection the controller will close the
valve, so that there will be no liquid flow in the evaporator. In this
way it is certain that the valve will close when the compressor has
stopped, but it also requires some wiring.
You can obtain this function with a signal via the data
communication, so the wiring can be reduced.
Not automatic
The controller has not been prepared for the function, so you will
have to set all the parameters and connections yourself. On last
page in the appendix you can see how you select the parameters.
Compressor control
Here you have to find the parameter releasing the status on the
Injection output. The parameter is called “AKC ON” or "Injection
ON.
Controllers with AKV control
Here you have to find the parameter that can force-control the
AKV valve. The parameter is called “Force close”. You will find it in
the group named “Forced closing” or “For Danfoss only”.
Start with the menu display you see when you select controllers.
If the word “Automatic” appears next to the controller, it is a new
controller which has been prepared for this function.
AKM Manual RI0XBh02 © Danfoss 11-2010

Appendix N - continued
Change of alarm limit
Principle
This function changes the set alarm limit in the different
controllers.
The function is primarily used in refrigerating systems where it is
difficult to maintain the required temperature on extremely hot
summer days.
The alarm limit is changed as a function of a room temperature
measurement, and the change may be up to 10 K from the
starting value. The override may also be made dependent on the
outdoor temperature, so that it only starts operating when the
outdoor temperature exceeds a set value.
There are two ways of changing the alarm temperature:
- one where an existing alarm limit in the controller is displaced
- one where a new setting is made of the existing alarm limit.
Alarm limit direct
The function in principle works in the same way as “Alarm limit
offset”, but the alarm limit is set differently in the different
controllers. For a start all the connected controllers must have
the same alarm limit setting. This value is also set in the override
function. When the override function then is activated, another
value will be set in all the connected controllers. This value will
now apply until it is overwritten by yet another value.
The maximum value that can be set will be 10 K higher than the
starting value.
When “Alarm limit direct” is used, it will be necessary to gather all
controllers with the same alarm limit value in their own individual
override functions.
The override value depends on the values set for the indoor
temperature. If there is a difference of 5 K between the two
settings, the override value will also be 5 K.
Alarm limit offset
The function is activated when the indoor temperature reaches
the set range.
The function may also be made dependent on the outdoor
temperature, so that the function will only be activated if the
outdoor temperature exceeds a set value.
Indoor
If the function is released by the outdoor temperature at a time
when the indoor temperature is in the active range, the override
will start with the corresponding step.
The override function may be attached to controllers with
different alarm limits, as it is a displacement of the alarm limit that
is made.

Defrost control
Cental defrost
The control function (override) enables you to define and start a
number of defrost cycles.
Co-ordinate Defrost
The function enables delaying the cooling until all controllers are
finished defrosting.
Def. start
Def. relay 1
Def. relay 2
Hold after defrost
When the defrost has been started, it is up to the individual
controllers to determine how it is to be terminated again. In some
it may stop based on time, in others based on tempera­ture.
AKM When the override function has received a signal from all the
selected parameters that the defrost has been terminated, it will
cancel the signal “Hold after defrost”.
When the controllers “lose” this signal, the regulating functions
will be released. The normal functions following a defrost cycle
can now start.

Appendix N - continued
P0 - Optimisation
Principle
The control function (override ) makes it possible for you to optimise the suction pressure so that it will be adapted to the system’s
actual load. During the optimisation data are collected that tell
you which refrigeration points are most heavily loaded.
System requirements
Max. 60 refrigeration points (sections) in one group.
Max. three groups.
Data should max. be uploaded from 100 refrigeration points in
one DANBUSS connection. Too many will create too much traffic
on the data communication.
Coming controllers:
The AKM programme must know the controllers that are used in
the P0 optimisation. The code number and software version for
these controllers are described in a file named ”akctype.ini”. This
file is continuously updated at Danfoss.
If you install a new controller in the refrigerating system and the
AKM programme does not know this controller, it may be necessary to update the mentioned file. Please contact Danfoss.
The individual controllers handle the temperature control in the
refrigeration appliances. Some controllers control two, others
three refrigeration points in the same appliance. The load and
operating condition of each refrigeration point are continuously
uploaded to the gateway via the data communication. The collected data are accumulated here and the ”most heavily loaded”
refrigeration point identified. An adaptation will now be made of
the suction pressure so that the air temperature at the refrigeration point is maintained. Only after a period of, say, 20 minutes,
or if the operating condition of the refrigeration point is changed
(defrost, cutout, etc.) can another refrigeration point be designated as the ”most heavily loaded one”.
It is the gateway that collects data from the refrigeration points
and it is the gateway that transmits an offset signal to the compressor control so that the suction pressure reference is changed
to suit the needs at the ”most heavily loaded” refrigeration point.
History
Here you accumulate the refrigeration points which during the
period have had the greatest influence on the P0 optimisation.
On the y-axis you can see for how many hours the P0 optimisation
has been locked to the relevant refrigeration points.
In a stable system there will not normally be major deviations.
If there are major differences of the contents of a 24-hour overview
and a weekly survey, this difference should be examined.
24-hour overview
Weekly overview
The set min./max. limits for the suction pressure will of course be
observed.
The time during which a refrigeration point has been designated
”the most heavily loaded one” will be summed up in a log (history)
in the shape of minutes. These data can be presented in a display
containing ”the last 24 hours” and ”the last 168 hours (one week)”.
The oldest values will continuously be overwritten.
It will typically be the same pattern that is formed on the two
charts, but if ”new ones” emerge and differ from the rest this
should be examined more closely.

Day / night control
Time schedule
Principle
This function transmits a signal to selected controllers. The signal
can e.g. be used for raising the temperature reference and for
raising the suction pressure reference.
Principle
The control function (override) enables you to define a number of
time schedules.
Override function
Example of use:
Input signal for day/night control.
When the individual controllers receive the signal, the reference
will be changed by the value set in the individual controllers.

Principle of selection of parameters
Principle
Each controller in the whole system contains hundreds of parame­
ters. And if we have a look at just one controller, it will use the
given parameters defined by the factory. However, when you have
to configure an override function here, it will be necessary for you
to define one specific parameter, and one only, in one specific
controller in order for the function to be a success. For certain
overrides you will have to select several parameters as signal
givers, and maybe quite a number of controllers as receivers.
Manual
When you select one specific parameter for an control function
(override), it should be done in this way:
1. Select the controller address (the word “Automatic” does not
appear on the line)
2. Press “Define”.
Override function
(Function control)
Automatic
Wherever possible we have made this selection easier. We have
put in an “automatic” function which will itself recognize the
override function you are configuring. This recognition will
produce the result that you will see the word “Automatic” when
you have to select controllers. In this way you do not have to move
way down in the controller’s menu to find the very parameter
needed for the function - you can select it on controller level.
3. Select a line and press “Next”.
The parameter you are selecting
may be selected for other
control­lers of the same type and
software version at one go. But
it may also be defined for just
one address.
4. Press “Next”.
HOWEVER - as it appears from the display - there are also some
controllers that do not have this built-in automatic function. So
here you have to select the controller’s parameters, as shown in
address 50 and 51.
130
5. Find the function group containing the required parameter.
6. Select the parameter and press “Add”, so that it is placed in the
upper white field of the display.
7. Press “Next”.
8. You have now selected a parameter in a controller, and it can
now be used in an override function.
