Introduction
Application
Complete refrigeration appliance control for SemiPlugin refrigeration appliances.
• Cabinets with flammable refrigerants
• Where the amount of refrigerant is divided across several circuits
• Where condensation heat is removed using brine
Advantages
• Energy optimisation of the whole refrigeration appliance
• One controller for several different refrigeration appliances
• Integrated display at the front of the controller
• Built-in data communication
• Built-in clock function with power reserve
Principle
The temperature in the appliance is registered by one or two
temperature sensors which are located in the air flow before the
evaporator (S3) or after the evaporator (S4) respectively. A setting
for thermostat, alarm thermostat and display reading determines
the influence the two sensor values should have for each individual function.
In addition product sensor S6, which can be optionally placed in
the appliance, can be used to register the temperature near the
required product in a certain place within the appliance.
The temperature of the evaporator is registered with the S5 sensor
which can be used as a defrosting sensor.
In addition to the output for the compressors, the controller has 5
relay outputs for dedicated applications.
Functions
• Day/night thermostat
• Product sensor S6 with separate alarm limits
• Switch between thermostat settings via digital input
• Start of defrost via schedule, digital input or network
• Natural or electric defrost
• Stop of defrost on time and/or temperature
• Coordination of defrost across several controls
• Pulsing of fans when thermostat is satisfied
• Case cleaning function for documentation of HACCP procedure
• Rail heat control via day/night load or dew point
• Door function
• Control of two compressors
• Control of night blinds and light
• Factory calibration that will guarantee a better measuring
accuracy than stated in the standard EN ISO 23953-2 without
subsequent calibration (Pt 1000 ohm sensor)
• Integrated MODBUS communication with the option of mounting a LonWorks or DANBUSS

Regulation
The controller can be used for:
On/off coupling of the two compressor outputs
Output 1 will form the base load, and output 2 will connect a
lower capacity so that the variation of the cabinet temperature is
kept to a minimum.
Regulation with two compressors
When the controller calls for refrigeration, compressor 1 will be
cutin to the circuit first.
After the delay time, compressor 2 will be coupled to the circuit.
When the temperature has reached the middle of the differential,
compressor 2 will be cut out.
Compressor 1 will continue until the temperature has reached the
cut-out value. Then it will cut out. When the temperature again
reaches the middle of the differential, compressor 1 will be cutin
to the circuit again.
If compressor 1 cannot maintain the temperature within the differential, compressor 2 will also be cutin to the circuit.
The compressor's settings for ”Min On time” and ”Min Off time”
will always have top priority during normal regulation. But if one
of the override functions is activated, the ”Min On time” will be
disregarded.

Temperature control
The temperature in the appliance is registered by one or two
temperature sensors which are located in the air flow before the
evaporator (S3) or after the evaporator (S4) respectively. A setting
for the thermostat, alarm thermostat and display reading determines how much the two sensor values should influence each
individual function, e.g. 50% will produce an equal value from
both sensors.
There are separate settings for day operation and night operation.
Temperature monitoring
Just as it is possible for the thermostat, the alarm monitoring can
be set with a weighting between S3 and S4 so that you can decide
how much the two sensor values should influence the alarm
monitoring. Minimum and maximum limits can be set for alarm
temperature and time delays. A longer time delay can be set for
high temperature alarms after defrosting, appliance cleaning or
start-up.
Thermostat bands
Thermostat bands can be used beneficially for appliances where
different product types are stored which require different temperature conditions. It is possible to change between the two
different thermostat bands via a contact signal on a digital input.
Separate thermostat and alarm limits can be set for each thermostat band – also for the product sensor.
Night setback of thermostat value
In refrigeration appliances there may be big load differences
between the shop’s opening and closing hours, especially if night
lids/blinds are used. The thermostat reference may be raised here
without it having any effect on the product temperature.
Change-over between day and night operation can take place, as
follows:
• via an external switch signal.
• via a signal from the data communication system.
Product sensor
A separate optional product sensor S6, which may be placed
in the appliance, can also be used and which can register and
monitor the temperature in the warmest part of the appliance.
There are separate alarm limits and time delays for the product
sensor.
S7 brine sensor
The temperature at the brine inlet is monitored by the S7
temperature sensor. If the temperature gets higher than the set
value, the controller will reduce the cooling capacity, so that the
strain on the heat exchanger is reduced.
For two-compressor operation, compressor 2 will be taken out of
operation.

Appliance cleaning
This function makes it easy for the shop’s staff to carry out a cleaning
of the appliance according to a standard procedure.
Appliance cleaning is activated via a signal – as a rule via a key switch
placed on the appliance.
Appliance cleaning is carried out via three phases:
1 - at the first activation the refrigeration is stopped, but the fans keep
on operating in order to defrost the evaporators. ”Fan” is shown on
the display.
2 - at the second activation the fans are also stopped and the
appliance can now be cleaned. ”OFF” is shown on the display.
3 - At the third activation refrigeration is recommenced. The display
will show the actual appliance temperature (o97 setting).

Documentation
When appliance cleaning is activated a cleaning alarm is transmitted
to the normal alarm recipient. A later processing of these alarms will
document that the appliance has been cleaned as often as planned.
Alarm monitoring
There are no temperature alarms during appliance cleaning.
Defrost
Depending on the application you may choose between the following
defrost methods:
Natural:
Here the fans are kept operating during the defrost
Electric:
The heating element is activated
Defrost sequence
1) Defrost
2) Waiting position after defrost
3) Drip off
4) Delay of fan
Start of defrost
A defrost can be started in different ways
Interval: Defrost is started at fixed time intervals, say, every eighth hour. An interval must ALWAYS be set to a "higher"
value than the period set between two defrostings when a
schedule or network signal is used.
Refrigeration time: Defrost is started at fixed refrigeration time
intervals, in other words, a low need for refrigeration will
”postpone” the defrost
Schedule: Here defrost can be started at fixed times of the day and night. However, max. 6 times
Contact: Defrost is started with a contact signal on a digital input
Network: The signal for defrost is received from a system unit
via the data communication
Manual: An extra defrost can be activated from the controller’s lowermost button
All the mentioned methods can be used at random – if any of them is
activated a defrost will be started.
Stop of defrost
Defrosting can be stopped by either:
• Time
• Temperature (with time as safety).

Coordinated defrost
There are two ways in which coordinated defrost can be arranged.
Either with wire connections between the controllers or via data
communication
Wire connections
The digital input DI2 is connected between the current controllers.
When one controller starts a defrost all the other controllers will
follow suit and likewise start a defrost. After the defrost the individual controllers will move into waiting position. When all are in
waiting position there will be a change-over to refrigeration.
Max. 10
System manager
Coordination via data communication
Here the system unit handles the coordination.
The controllers are gathered in defrosting groups and the system
unit ensures that defrosting is started in the group according to a
weekly schedule.
When a controller has completed defrosting, it sends a message
to the system unit and then goes into a waiting position. When
every controller in the group is in a waiting position, refrigeration
is again permitted in all the individual controllers.
Defrost on demand
Based on refrigeration time
When the aggregate refrigeration time has passed a fixed time, a
defrost will be started.
Melting function
This function will stop the air flow in the evaporator from being reduced by frost created by uninterrupted operation for a long time.
The function is activated if the thermostat temperature has
remained in the range between -5°C and +10°C for a longer
period than the set melting interval. The refrigeration will then be
stopped for the set melting period. The frost will be melted so that
the air flow and hence the evaporator’s capacity will be greatly
improved.
Real-time clock
The controller has a built-in real-time clock which can be used to
start defrosts. This clock has a power reserve of four hours.
If the controller is equipped with data communication, the clock
will automatically be updated from the system unit.

Railheat
It is possible to pulse-control the power to the rail heat in order to
save energy. Pulse control can either be controlled according to
day/night load or dew point.
Pulse control according to day and night
Various ON periods can be set for day and night operation.
A period time is set as well as the percentage part of the period in
which the rail heat is ON.
Pulse control according to dew point
In order to use this function a system manager of the type AK-SM
is required which can measure dew point and distribute the current dew point to the appliance controllers. For this the rail heat’s
ON period is controlled from the current dew point.
Two dew point values are set in the appliance control:
• One where the effect must be max. i.e.100%. (o87)
• One where the effect must be min. (o86).
At a dew point which is equal to or lower than the value in 086,
the effect will be the value indicated in o88.
In the area between the two dew point values the controller will
manage the power to be supplied to the rail heat.
During defrosting
During defrosting the rail heat will be controlled by the setting in
"d27" (Off, On or pulsing).
Rail heat
Dew point
Fan
Pulse control
To obtain energy savings it is possible to pulse control the power
supply to the evaporator fans.
Pulse control can be accomplished in one of the following ways:
- during the thermostat’s cutout period (cold room)
- during night operation and during the thermostat’s cutout
period (appliance with night lid /blind)
A period of time is set as well as the percentage of this period of
time where the fans have to be operating.
Cutout of fans during plant breakdowns
If the refrigeration in a breakdown situation stops, the
temperature in the refrigeration appliance may rise as a result of
the power supply from fans. In order to prevent this situation the
controller can stop the fans if the temperature at S5 exceeds a set
limit value.

Light function
The function can be used for controlling the light in a refrigeration
appliance or in a coldroom. It can also be used for controlling a
motorised night blind.
The light function can be defined in three ways:
- the light is controlled via a signal from a door contact. Together
with this function a time delay can be set so that the light is kept
on for 2 minutes after the door has been closed.
- the light is controlled via the day/night function
- the light is controlled via the data communication from a system
unit.
Here there are two operational options if data communication
should fail:
- The light can go ON
- The light can stay in its current mode.
The light load must be connected to the NC switch on the relay.
This ensures that the light remains on in the appliance if power to
the controller should fail.
The light is switched off when "r12" (Main switch) is set to off (see
o98).
Digital inputs
There are two digital inputs DI1 and DI2 with contact function and
one digital input DI3 with high voltage signal.
DI1 and DI2 input can be used for the following functions:
- Retransmission of contacts position via data communication
- Door contact function with alarm
- Starting a defrost
- Main switch - start/stop of cooling
- Night setback
- Thermostat bands switch
- General alarm monitoring
- Case cleaning
- Override of night blinds
- Case shut down
- Coordinated defrost (DI2 only)
DI 3 can receive a signal from the compressors' safety circuit. When
the voltage at the input is broken, the controller will deliver the
alarm. "A97- Comp. Safety".
Night blind
Motorised night blind can be controlled automatically from the
controller. The night blinds will follow the status of the light
function. When the light is switched on, the night blinds opens
and when the light is switched off, the night blinds close again.
When the night blinds are closed, it is possible to open them and
switch on the light using a switch signal on the digital input. If this
input is activated, the night blinds will open and the refrigeration
appliance can be filled with new products. If the input is activated
again, the blinds close again.
A night blind is open and light is switch on when the appliance
cleaning function is activated.
A setting can define that the night blind is open when "r12" (Main
switch) is set to off (see o98).
When the night blind rolls down, the fans will stop for so that the
air circulation does not interrupt the positioning of the blind. The
desired stop time must be set in P65.
The motor for the night blinds must be connected to the same
relay as the light function.
Door contact
The door contact function can via the digital inputs be defined for
two different applications:
Alarm monitoring
The controller monitors the door contact and delivers an alarm
message if the door has been opened for a longer period than
the set alarm delay.
Alarm monitoring and stop of refrigeration
When the door is opened the refrigeration is stopped and the
fan are stopped and light switch on.
If the door remains open for a longer time than the set restart
time, refrigeration will be resumed. This will ensure that
refrigeration is maintained even if the door is left open or if the
door contact should be defective. If the door remains open for
a longer period than the set alarm delay an alarm will also be
triggered.

User Guide | Controller for SemiPlugin appliance, AK-CC 460
Data communication
The controller has fixed built-in MODBUS data communication.
If there is a requirement for a different form of data
communication, a Lon RS 485 or DANBUSS module can be
inserted in the controller.
The connection must then be to terminal RS 485.
(To use a Lon RS 485 module and gateway type AKA 245 the
Gateway software must be Version 6.20 or higher.)
Display
The controller has one plug for a display. Here display type EKA
163B or EKA 164B (max. length 15 m) can be connected.
EKA 163B is a display for readings.
EKA 164B is both for readings and operation.
The connection between display and controller is with a cable
which has a plug at both ends.
If the distance between display and controller is greater than 15
m, the connection must take another form.
An extra module must also be mounted in the controller if data
communication is used.
The built-in MODBUS data communication is used so that the
display connection and the data communication to the other
controllers must take place via a module. The module can be:
Lon RS 485, DANBUSS or MODBUS.
When a display is to be connected to the built-in MODBUS, the
display can advantageously be changed to a type with screw
terminals. I.e. the type EKA 163A or EKA 164A.
If connection of two displays is required, one must be connected
to the plug (max. 15 m) and the other must then be connected to
the fixed data communication.
The controllers address must be set higher than 0 in order for the
display to be able to communicate with the controller.
! Address o03 > 0
Important
All connections to the data communication MODBUS, DANBUSS
and RS 485 must comply with the requirements for data
communication cables. See literature: RC8AC.

Normal display
Normally the temperature value from one of the two thermostat sensors S3 or S4 or a
mixture of the two measurements is displayed. In o17 the ratio is determined.
If the S6 temperature is to be shown, this must be defined in setting o97.
Thermostat
Set point
Regulation is based on the set value plus a displacement, if applicable. The value is set via a
push on the centre button.
The set value can be locked or limited to a range with the settings in r02 and r 03.
The reference at any time can be seen in "u91 Cutout temp".
Differential
When the temperature is higher than the reference + the set differential, the compressor
relay will be cut in. It will cut out again when the temperature comes down to the set reference.

Start / stop of refrigeration
With this setting refrigeration can be started, stopped or a manual override of the outputs
can be allowed. (For manual control the value is set at -1. Then the valve outlet and the
relay outlets can be force-controlled by the respective reading parameters (u58, etc.). Here
the read value can be overwritten.)
Start / stop of refrigeration can also be accomplished with the external switch function
connected to a DI input.
Stopped refrigeration will give a ”Standby alarm”.
Night setback value
The thermostat’s reference will be the setpoint plus this value when the controller changes
over to night operation. (Select a negative value if there is to be cold accumulation.)
Thermostat function
This is where it is displayed how the thermostat is operating.
1=ON/OFF thermostat (the regulation is set to application 1, and the differential is "r01")
Selection of thermostat sensor S4% during day operation
Here you define the sensor the thermostat is to use for its control function. S3, S4, or a
combination of them. With the setting 0%, only S3 is used (Sin). With 100%, only S4.
Melt function
Only for control of refrigeration (-5 to +10°C). The function ensures that the evaporator will
not be blocked by frost. Here you set how often the function is to stop the refrigeration
and hence transform the frost to water (or ice if there is too much frost).

Alarm
The controller can give an alarm in different situations. When there is an alarm all the lightemitting diodes (LED) will flash on the controller front panel, and the alarm relay will cut in.
Alarm delay (short alarm delay on air temperature)
If the upper or the lower alarm limit values are exceeded, a timer function will commence.
The alarm will not become active until the set time delay has been passed. The time delay
is set in minutes.
A03
With data communication the importance of the individual alarms can be defined. Setting is carried out in the “Alarm
destinations” menu. (Gateway + AKM)
Alarm delay
Time delay for door alarm
The time delay is set in minutes.
The door function is defined in o02 or o37.
Time delay for cooling (long alarm delay)
This time delay is used during start-up, during defrost, immediately after a defrost.
There will be change-over to the normal time delay (A03) when the temperature has
dropped below the set upper alarm limit.
The time delay is set in minutes.
Upper alarm limit
Here you set when the alarm for high temperature is to start. The limit value is set in °C
(absolute value).
The limit value will be raised during night operation. The value is the same as the one set
for night setback, but will only be raised if the value is positive.
Lower alarm limit
Here you set when the alarm for low temperature is to start. The limit value is set in °C
(absolute value).

exceeded. The time delay is set in minutes.
Alarms will not activate when the setting is set to the maximum value.
Delay of a DI1 alarm
A cut-out/cut-in input will result in alarm when the time delay has been passed. The function is defined in o02.
Delay of a DI2 alarm
A cut-out/cut-in input will result in alarm when the time delay has been passed. The function is defined in o37
Signal to the alarm thermostat
Here you have to define the ratio between the sensors which the alarm thermostat has to
use. S3, S4 or a combination of the two.
With setting 0% only S3 is used. With 100% only S4 is used
Time delay on S6 (product sensor) for pull-down (long alarm delay)
This time delay is used for start-up, during defrosting, immediately after a defrost and after
an appliance clean.
A change is carried out to standard time delay (A26) when the temperature has reached
below the set upper alarm limit.
The time delay is set in minutes.
Hot brine alarm
If the S7 brine temperature gets higher than the set value, an alarm will be delivered. If two
compressors are in use, compressor 2 will be stopped for as long as the temperature is too
high.

Output "Compressor 1" only. ("Compressor 2" is off.)
Compressor off-time at sensor error
Output "Compressor 1"
The LED on the controller’s front will show whether refrigeration is in progress.
Defrost
The controller contains a timer function that is zeroset after each defrost start.
The timer function will start a defrost if/when the interval time is passed.
The timer function starts when voltage is connected to the controller, but it is displaced
the first time by the setting in d05.
If there is power failure the timer value will be saved and continue from here when the
power returns.
This timer function can be used as a simple way of starting defrosts, but it will always act
as safety defrost if one of the subsequent defrost starts is not received.
The controller also contains a real-time clock. By means of settings of this clock and times
for the required defrost times, defrost can be started at fixed times of the day.
Defrost start can also be accomplished via data communication, via contact signals or
manual start-up.
All starting methods will function in the controller. The different functions have to be set,
so that multiple defrosts are avoided..
Defrost can be accomplished with electricity.
The actual defrost will be stopped based on time or temperature with a signal from a
temperature sensor.
Defrost method
Here you set whether defrost is to be accomplished with electricity or (none).
During defrost the defrost relay will be cut in.

Interval between defrost starts
The function is zeroset and will start the timer function at each defrost start. When the
time has expired the function will start a defrost.
The function is used as a simple defrost start, or it may be used as a safeguard if the normal
signal fails to appear.
If master/slave defrost without clock function or without data communication is used, the
interval time will be used as max. time between defrosts.
If a defrost start via data communication does not take place, the interval time will be used
as max. time between defrosts.
When there is defrost with clock function or data communication, the interval time must
be set for a somewhat longer period of time than the planned one, as the interval time will
otherwise start a defrost which a little later will be followed by the planned one.

Time staggering for defrost cutins during start-up
The function is only relevant if you have several refrigeration appliances or groups where
you want the defrost to be staggered in relation to one another. The function is furthermore only relevant if you have chosen defrost with interval start (d03).
The function delays the interval time d03 by the set number of minutes, but it only does
it once, and this at the very first defrost taking place when voltage is connected to the
controller.
The function will be active after each and every power failure.

Rail heat control
The rail heat can be controlled in several ways:
0: The function is not used
1: Pulse control is used with a timer function following the day/night operation (o41 and
o42)
2: Pulse control is used with a dew point function. This function requires that a signal is
received about the dew point value. The value is measured by a system manager and sent
to the controller via the data communication.
Dew point value where the rail heat is minimum
This function is discussed earlier in the manual.
Dew point value where the rail heat is maximum
This function is discussed earlier in the manual.
Lowest permitted rail heat effect
Here the % part of the effect to be achieved when the dew point value is minimum.

1 - High temperature alarms
2 - Low temperature alarms
4 - Sensor error
8 - Digital input is activated for alarm
16 - Defrost alarms
32 - Miscellaneous
The groups that are to activate the alarm relay must be set by using a numerical value
which is the sum of the groups that must be activated.
(E.g. a value of 5 will activate all high temperature alarms and all sensor errors. 0 will cancel
the relay function)

Fault message
In an error situation the LED’s on the front will flash and the alarm relay will be activated. If you push the top button in this situation you can see the
alarm report in the display.
There are two kinds of error reports - it can either be an alarm occurring during the daily operation, or there may be a defect in the installation.
A-alarms will not become visible until the set time delay has expired.
E-alarms, on the other hand, will become visible the moment the error occurs.
(An A alarm will not be visible as long as there is an active E alarm).

Operation
Controller/Display
The values will be shown with three digits, and with a setting you
can determine whether the temperature is to be shown in °C or in
°F.
Get a good start
With the following procedure you can start regulation very quickly:
1 Open parameter r12 and stop the regulation (in a new and not
previously set unit, r12 will already be set to 0 which means
stopped regulation.)
Light-emitting diodes (LED) on front panel
The LED’s on the front panel will light up when the relevant relay
is activated.
= Refrigeration
= Defrost
= Fan running
2 Select electrical connection based on the drawings on page 24
The light-emitting diodes will flash when there is an alarm.
In this situation you can download the error code to the display
and cancel/accept the alarm by giving the top button a brief push.
5 Go through the survey of factory settings. Make any necessary
changes in the respective parameters.
The buttons
When you want to change a setting, the upper and the lower
buttons will give you a higher or lower value depending on the
button you are pushing. But before you change the value, you
must have access to the menu. You obtain this by pushing the
upper button for a couple of seconds - you will then enter the column with parameter codes. Find the parameter code you want to
change and push the middle button until value for the parameter
is shown. When you have changed the value, save the new value
by once more pushing the middle button.
3 Open parameter o61 and set the electric connection number in
it
4 Open parameter r12 and start the regulation

Configuration of alarm relay
The alarm relay will be activated upon an alarm signal from the following
groups:
1 - High temperature alarms
2 - Low temperature alarms
4 - Sensor error
8 - Digital input is activated for alarm
16 - Defrost alarms
32 - Miscellaneous
The groups that are to activate the alarm relay must be set by using a
numerical value which is the sum of the groups that must be activated.
(E.g. a value of 5 will activate all high temperature alarms and all sensor
errors).

Factory setting
If you need to return to the factory-set
values, it can be done in this way:
- Cut out the supply voltage to the
controller
- Keep upper and lower button
depressed at the same time as you
reconnect the supply voltage
*) Can only be set when regulation is stopped (r12=0)
**) Can be controlled manually, but only when r12=-1
***) With access code 2 the access to these menus will be limited
Forced control
If you need to force-control an output, you should set r12 to -1 (manual mode). You should then select
the relevant relay function, e.g. u58. Go to the function by pressing the middle button. Select On.

connected here.
Data communication
If data communication is used, it is important that the installation
of the data communication cable is performed correctly.
See separate literature No. RC8AC…
Electric noise
Cables for sensors, DI inputs and data communication must be
kept separate from other electric cables:
- Use separate cable trays
- Keep a distance between cables of at least 10 cm
- Long cables at the DI input should be avoided
Installation considerations
Accidental damage, poor installation, or site conditions, can give
rise to malfunctions of the control system, and ultimately lead to a
plant breakdown.
Every possible safeguard is incorporated into our products to
prevent this. However, a wrong installation, for example, could still
present problems. Electronic controls are no substitute for normal,
good engineering practice.
Danfoss wil not be responsible for any goods, or plant components, damaged as a result of the above defects. It is the installer's
responsibility to check the installation thoroughly, and to fit the
necessary safety devices.
Special reference is made to the necessity of signals to the
controller when the compressor is stopped and to the need of
liquid receivers before the compressors.
Your local Danfoss agent will be pleased to assist with further
advice, etc.
