5.2
Field Bus = Danfoss Controller
The PC tool is connected via the COM port to the
Danfoss Controller.
In the middle of the main window two tabs
appear containing two tables and a block each.
The first tab shows the current values and the
second the averages. Both tabs are constructed
identically, so only the tab with current values is
described herein.
The first larger table shows the current values
of the 96 possible digital measuring point
addresses. The second table displays the current
values of a total of 32 possible analog measuring
point addresses.
 or  information concerning the relay status.
These icons may only appear if the relay is used
at this address. The icons reflect the energization
state of the relay, regardless of the parameter
setting operating/quiescent current or the relay
contacts used.
The alarm status is shown by the coloured
background of the cell.
The cells of inactive measuring points are grey
and empty.
The cells with inactive measuring points, but
with active relays are shown with light blue
background colour and the relay status.
The cells with active measuring points display
the actual value with different background
colours depending on the alarm status of the
measurement point. The definitions of the
colours can be looked up in Options.
In addition to the current value each cell contains
further information about the respective
measuring point: The following icons may be
displayed on the left next to the current value:
#  means that this measuring point needs
maintenance. The maintenance for analog
measurement points is monitored and
reported by the EP module, so here the display
is simultaneous for all four possible analog
measuring points.

Field Bus = Danfoss Controller
(Continued)
When the mouse pointer hovers over the cell, a
tool tip window pops up showing the following
additional information:
- Relay or measuring point address including the
current measuring value
- Nomenclature number with the gas type of the
connected measuring point
- Measuring range and unit of the connected measuring point
- Active alarms
- Present current of the analog output
- Number of days left until next maintenance
The lower block displays the control information
(set point) of the 16 possible analog outputs.
It has already been converted to the output
current range of 0-22 mA (measuring range 4-20
mA).
5.2.1
Display of possible error
messages
A distinction is made between system errors and
measuring point errors.
Messages only concerning the measured value
will appear in the cell instead of the valid current
value. This also includes the communication error
to the sensor board or the digital sensor head.
Messages generated by the gas detection
controller will appear in the upper left corner of
the table. The messages are displayed in the form
of an error code. The detailed breakdown can be
read in the tool tip.
If there is an error at a measuring point, the gas
detection controller, too, will generate an error
message; therefore, the two messages always
occur together.
If the current value is displayed, but highlighted
in yellow, then there is a configuration conflict
between gas detection controller and gas
detection unit.
An automatic measuring point configuration was
deliberately omitted in order to obtain a high
level of security when configuring.
The installer must consciously enter the
configuration of each measuring point
accordingly.

Parameters
Attention:
Due to the hard real-time behaviour the
parameter data can only be exchanged if
the device is in special mode.
Therefore, the parameter buttons are
only enabled in special mode.
6.1
Addressing
This dialog opens via Parameters  Addressing
or via the quick access toolbar with the icon .
The device to which the PC tool is connected to
via COM port will always be addressed. With
the Change button, the new address and any
configuration is taken over.
6.1.1
Addressing of gas detection
controller
The slave address of the gas detection controller
is assigned here.
It is required on the M-Bus for communication
with an alarm master unit.
6.1.2
Addressing of expansion
module
Here the slave address is assigned to an
expansion module. It is required on the field
bus for communication with the central gas
controller. Addresses from 1 to 7 are allowed,
since there is a maximum of seven expansion
modules.
In addition, the configuration of the expansion
module is set here.
5. column:
Gas type: Here you can select the gas type of the
connected analog sensor. Corresponds to the
settings in the MP Parameters menu.
1. column:
Number of analog input with respect to the
connected device. Corresponds to MP number
1 - 4 in MP Parameters.
2. column:
Four analog inputs can be set. They are available
at all times, so the addresses are always reserved
and the buttons AP (X) to AP (X+3) are always
active. The first four analog inputs can only be
set in the controller, so the AP addresses of the
expansion module with address 1 start in line 1
with address AP 5.
6. column:
Measuring range: Here you can set the
measuring range of the connected analog sensor.
Corresponds to the settings in the MP Parameters
menu.
3. column:
Since there are only analog inputs, the buttons in
the third column always remain analog.
4. column:
Active: Here you can enable or disable the
analog inputs. Corresponds to the settings in the
MP Parameters menu.

6.1.3
Addressing of gas detection
units
Here the slave address is assigned to a sensor
board. It is required on the field bus for
communication with the GC central device.
Addresses are allowed from 1- 96, because there
can be a maximum of 96 digital measuring
points.
In addition; the desired configuration of the
sensor boards is set here.
1. column:
MP number related to the connected device.
Corresponds to the MP number 1 – 4 in MP
Parameters, with Premium units having a
maximum of two measuring points.
Therefore, the P3 and P4 is always inactive and
greyed out.
2. column:
Up to two DP can be set. With each additional
measuring point the sensor board occupies
an additional address on the field bus. With
two activated measuring points the addresses
X, X + 1 are occupied. These addresses must
not be assigned to any other sensor board! The
superordinate controller can detect address
errors (multiple uses) only via incorrect bus data.
3. column:
Here you can set whether the measured values
should come from the digital sensor head or the
analog input.
4. column:
Active: Since each additional measuring point
occupies one address on the field bus, it is
assumed that this measuring point is physically
present and is therefore automatically activated
when addressed. However, it can be deactivated
manually.
© Danfoss | DCS (MWA) | 2018.06
5. column:
Gas type: Here you can select the gas type of the
measuring point. Double gas type configurations
are not allowed, therefore gas types already used
are deactivated in the selection list, displayed
greyed out and can only be used as analog
measurement points several times.
Corresponds to the setting in the MP Parameters.
6. column:
Measuring range: The measuring range of the
measuring point is set here. Corresponds to the
setting in the MP Parameters. It is essential that
it corresponds to the measuring range of the
sensor heads.

Note: Parameters can only
be written into a device
directly connected to the PC tool.
If you want to enter the same parameters for a
plurality of measuring points, you do not need to
upload them individually.
In the dialog, there is a button called Duplicate.
In this area there are also two input fields and
a button for specifying a start and end address.
The specified addresses are included when
transferring.
The Step button defines whether all measuring
points between the start and the end address
should be transmitted or only every second or
every third address.
12 | DKRCI.PS.S00.C1.02 | 520H12961
3. Button for Digital / Analog:
If digital is set, the addresses 1-96 can be set for
the digital measuring points in MP Address. If
analog is set, the addresses 1-32 can be set for
the analog measuring points in MP Address.
Two buttons are placed in the middle of the
upper half of the dialog:
1. Read MP: Here you load the parameters of
each measuring point from the selected device in
the dialog interface.
2. Write MP: Here you can upload the settings
from the dialog interface into the connected
device. This button is inactive, if you have
selected a device one level down.
All input fields must contain numbers.
If you make no or incorrect parameter entries
and you click on an Upload button, the fields
containing errors, are highlighted in yellow, an

Measuring point MP parameters
(Continued)
On the top right there is the file area with two
buttons:
Export: With this button the parameters of all
measuring points are successively read without
showing them in the dialog interface. At the
start of transmission, the button changes its text
to Cancel, so you can cancel the transfer at any
time by clicking on the same button; but then
the read data will be lost. The remaining buttons
are deactivated until the transmission has been
completed.
Import: After clicking on this button, you are
prompted to select the file you want to load.
Once the correct file is selected, all measuring
point parameters are consecutively uploaded to
the controller. All buttons are disabled during
this process.
If an incorrectly structured file is selected, the
transfer will not be admitted.
When the reading is finalized, you are prompted
to save the file in the .csv format. If you cancel
the storage process, all read data will be lost. For
storing them in a file, they have to be read again!
At the end of the specified filename, the text, MP’
is appended to make sure that the measuring
point parameters are stored here.
6.2.1
MP parameters description
In the middle of the dialog are all input fields for setting the measuring point parameters:
1. Active or Inactive indicates whether the measuring point should be activated (physically present).
2. Unlock or Lock indicates whether the measuring point should be (temporarily) blocked.
3. Gas Type: Here the gas type is assigned to the measuring point.
4. Measuring Range: Here the measuring range is assigned to the measuring point.
5. Threshold 1 - Threshold 4: Values of the alarm thresholds, each with its own function box for
- Alarm release at in- or decreasing concentrations
- Alarm release by current (CV) or average (AV) value.
6. Hysteresis: The measured value has to exceed or to fall below the alarm threshold by the hysteresis value, so that the alarm will be deleted.
7. CV ON Delay Time (sec): Switch-on delay for the release by the current value in seconds (not
applicable for Heavy duty units, it is always 0)

located in the upper part of the dialog:
1. Relay Address: Address of the relay to be parameterized.
2. Selection field for the targetdevice from which the
parameters have to be read.
Note: Parameters can only be written in the device directly connected to the PC tool.
3. Button for Alarm Relay / Signal Relay
(only GC central unit):
If Alarm Relay is set, you can set addresses from 1 to 32 for the alarm relays in Relay Address. If
Signal Relay is set, you can set addresses from 1 to 96 for the signal relays in Relay Address.
In the middle of the upper half of the dialog there are two buttons:
1. Read Relay: Here you download the parameters of the corresponding relay from the controller
into the dialog interface.
2. Write Relay: With this button you can write the final settings into the controller, with the parameters being stored under the specified relay address.
Same as for the measuring point parameters, there is also the Duplicate button and two input fields
for start and end address. Here the relay settings from the start to the end address are transmitted into
the controller.
With the Export button all relay parameters are read by the controller and you are prompted to save
the data in a CSV file. If you cancel the storage, all read data will be lost. The transmission can be
interrupted at any time the same way as for the measuring point parameters.
A previously selected file can be uploaded to the controller by means of the import button.

0
Analog output not active
1
Analog output active, but is overridden by the GC central unit (Setting is not available in GC controller as it and
only it can control)
10-100
Analog output active
The value indicates the factor how the measuring range is scaled to 4-20 mA, e.g. 100% requires 100% of the
range scaled to 4-20mA
10% only requires 10% of the range scaled to 4-20mA
b. Source for the values to be output: Current or average value.
c. Definition, which signal of all assigned MP will be output:
Min.(= minimum gas signal); average (= average calculation); Max.(= maximum gas signal)

System parameters (Continued)
9. Relay Multiplication: is opening an additional dialog for the relay multiplication.
This feature is available only in the Danfoss controller.
With the relay multiplication table it is possible to assign additional relay functions to an alarm in the system. This corresponds
to one reproduction of the source relay per entry.
The additional relay then follows the state of the source relay, but uses its own relay parameters to allow different needs of the doubled relay. The source relay can
be configured e.g. as a safety function
relay in de-energized mode whereas the doubled relay may be defined with flashing function or as horn function relay.
There is a maximum of 20 entries (Controller)
and three entries (Premium units) for IN and OUT relays. It is possible on the one hand to multiply one relay to further relays
or on the other hand to double max. 15
relays (Controller). In the column IN (source),
the relay that has been assigned is set to an alarm in MP Parameters.
In the column OUT (target) the additionally required relay is entered.
Next in the dialog System Parameters:
At the right side is the control range with buttons:
1. Address: Just as with the two previous parameter dialogs the system
dialog contains the control range of the addresses with the difference
that system parameters can also be read from a sensor head.
2. Input field for the address the parameters should be read from.
Note: Parameters can only be written in the device directly connected to the PC tool.
Just as with the two previous parameter dialogs, there are two buttons “Read device” and “Write device”.
With these buttons the system parameters are read from the device into the dialog or written back
into the device.
Unlike the other parameter dialogs, there is no Duplicate button, because the system parameters only
exist once.
The System Parameters dialog also has two file buttons to save the settings into a file or to upload
them from a file.
Unlike the other parameter dialogs, the system parameters are saved from the dialog interface into a
CSV file and uploaded from the file into the dialog interface.

Calibration at the local bus
Attention:
The calibration function can only be
used when the device is in special mode.
Therefore, the menu item and the button
for calibration are only active in special
mode.
Using this dialog, the sensor heads can be
recalibrated. The calibration is carried out via the
local bus. Please connect the PC software via the
COM port to the sensor board.
In the upper part of the dialog is a selection box
where you can define the target head. Directly
under it the current value of the set head is
displayed.
In the middle of the dialog there are three
register tabs: Report, Zero and Gain. Directly
below that you can find the system tray with
information on the calibration process. At the
bottom right the close button which quit the
dialog.
7.1
Register tab „Report“
The tab Report contains:
- Name of object
Here you can enter the name of the current object.
- Person in charge
Here you can enter the name of the responsible
person.
- a box with the path to the location of the calibration report. The file path can be selected
via the Search button.
Attention:
The entries in these fields are important
for the calibration, as this information will
appear in the calibration report.
The software prevents you from
switching to the calibration register tabs
before the object information fields have
not been completed.

Register tab „Zero“
The tab Zero contains:
- First Zero Offset
Here the first zero offset is displayed.
- New Zero Offset
Is displayed as soon as it is successfully calculated.
- Three buttons:
Step 1: Display
Step 2: Calculate
Step 3: Save
Prior to calibrating the zero point, you have to
display the current values by clicking on the
button Step 1: Display
If the values could be read successfully,
the corresponding message is displayed in the
system tray, and only then the button Step 2:
Calculate is enabled. The current values for the
display are permanently read, and the current
status is always shown in the window. No need
for pressing the button again.
When clicking on the button Step 2: Calculate
the zero calibration switches into the calculation
mode. The calculation of the new zero offset
is permanently executed and displayed in the
associated field. The values are therefore always
updated.
When the calculation has been successfully
completed, the current value in Current gas
value drops to 0 and the button Step 3: Save is
activated.
If you cancel the calibration now by closing the
dialog box or by changing over to another tab, a
message box will be activated asking if you want
to quit this function without saving. With the Yes
button you will definitely cancel the function,
with the No button you will return to the current
dialog.
If you cancel the function definitely or disconnect
the device, the recalculated zero offset value
is lost. After exiting the special mode, the last
stored zero offset is used again.
Note:
For calibrating the zero point, you need
zero gas or sample gas-free ambient air.
The measured value must not exceed
the 10% mark of the measuring range!
Sensors with higher deviation can no
longer be used.
In this case, the appropriate error message
appears in the system tray and the button “Step
3: Save” is disabled.
Use the button “Step 3: Save” for saving the
new zero offset which will be employed with
immediate effect. This can also be seen with
the display of all measuring points in the main
window. The permanent calculation mode has
finished now.

No need for pressing the button again.
When clicking on the button Step 2: Calculate
the gain calibration switches to the calculation
mode. The calculation of the new gain is
permanently executed and is based on the test
gas concentration.
If the value of the entered test gas concentration
is too high or too low, an error message will
appear.
The current status for the calculation is displayed
in the system tray beneath the tab.
When the calculation has been successful, the
current sensor sensitivity is displayed, the actual
value in Current gas value accepts the value of the
test gas concentration and the button Step 3:
Save is enabled.
If you cancel the calibration now by closing the
dialog box or by changing over to another tab, a
message box will be activated asking if you want
to quit this function without saving. With the Yes
button you will definitely cancel the function,
with the No button you will return to the current
dialog.
If you cancel the function definitely or disconnect
the device, the recalculated gain factor is lost.
After exiting the special mode, the last stored
gain factor is used again.

7.3
Register tab „Gain“ (Continued)
If the gain calibration was not successful, there
might be several reasons:
- If the sensor sensitivity is below 30%, the calibration of the gain is cancelled. The sensor is either too old and you can no longer calibrate
its gain, or there is no calibration gas present
on the sensor. Storage is not allowed in this
case, therefore, the buttons are disabled.
- If the sensor sensitivity is higher than 30%, but
lower than 40%, the gain is calibrated, but it is
noted that the sensor is defective; furthermore,
you should check if calibration gas is present on
the sensor.
- The calibration of gain is not possible with the
following error messages either.
Use the button Step 3: Save for saving the
new gain factor which will be employed with
immediate effect. This can also be seen with
the display of all measuring points in the main
window. The permanent calculation mode has
finished now.

Zero-point calibration of the
analog output
The tab AO contains:
- Board AOs
Here you can set whether the analog output of
the connected device should be calibrated. If
the box is not ticked, the device, in which the AO should be calibrated, will be set via the
selection field of the measurement points.
- AO1 and AO2:
Depending on the connected device type
there is either only the AO1 or additionally the
AO2.
- AO Offset from device
Here the current offset of the analog output is displayed.
- AO Offset to device
Here the new offset is set in the range of 160 to
700 (AD converter value)
- Three buttons:
Step 1: Display
Step 2: Calculate
Step 3: Save
Prior to calibrating the AO zero-point, you must
display the current values by clicking on the
button Step 1: Display. If the values could be
read successfully, the corresponding message
will be displayed in the system tray, and only then
the button Step 2: Calculate will be enabled. The
current values for the display are permanently
read, and the current status is always shown in
the window. No need for pressing the button
again.
When clicking on the button Step 2: Calculate
the AO zero-point calibration switches to the
calculation mode. The calculation of the new
signal zero offset is permanently executed and
displayed in the corresponding box. The values
are therefore always updated.
When the calculation has been successful, the
actual value is not added to it and the button
Step 3: Save is enabled.
If you cancel the calibration now by closing the
dialog box or by changing over to another tab, a
message box will be activated asking if you want
to quit this function without saving. With the Yes
button you will definitely cancel the function,
with the No button you will return to the current
dialog.
If you cancel the function definitely or disconnect
the device, the recalculated zero offset is lost.
After exiting the special mode, the last stored
zero offset is used again.
Note:
To calibrate the analog output zero, you
need an amperimeter to change it until
the value corresponds to the desired
zero.
If the calculation was not successful, the
corresponding error message appears in the
system tray and the button Step 3: Save is
disabled.
With the Step 3: Save button the new zero offset
is stored and will be used immediately.

Register tab “Burn” (selfcleaning by burning)
This tab Burn is for starting the process of heating
a pellistor sensor up for self-cleaning.
- The Start button sets the command for burning free.
- The Cancel button interrupts the burning process.
The buttons are only enabled for Pellistor sensors.
The function is for heating catalytic bead sensors
(pellistors) up to a higher temperature for a
certain time in order to remove any residues on
the heating wire.
It is used if the sensors show too low sensitivity
on some or all combustible gases due to dirt on
the filament.
Before starting the burn-off, a combustible test
gas - the best would be hydrogen - has to be
applied to the pellistor with a calibration cap in
order to intensify the combustion.
Note:
The burning cannot improve or undo the
natural aging!
The operation can be stopped with Cancel at any
time.

History of the data logger
Options:
In the upper half, you can manage all settings
for the measured value control of all measuring
points:
- If only the current value or the average value, or
both are monitored.
- If Periodic Record is active, monitoring is
continuously performed at certain time intervals.
- If Each Poll is active, storage is performed with
each measurement cycle.
Note:
This setting is not recommended for
extended periods of time, since the data
transfer between the devices is very fast
and the PC cannot keep up the speed.
- Poll rate in sec. represents the time interval in
which the data are written. As the PC timer
is not synchronized with the timer of the
device, there may be minimal time delays when
recording.
- If Periodic Record is not active, the values are written by the data logger only if the measured
value changes by the Difference value.
In the bottom half, the path is indicated where
the audit records are stored automatically.
Separate files for digital measurement points (DP)
and analog measurement points (AP) are started.
The corresponding files are marked by the
abbreviation DP or AP in the filename.
A consecutive number is automatically added
to the specified name of the file, so that the file
is not overwritten. If there are already files with
the same name in the specified directory, the
numbers will continue.
If Always ask for the path of history files is
active, a file storing dialog will appear when
starting the history, in order to control the path
right from the start.
Note:
Each dataset is directly written into
the file. Therefore, the file must not be
opened during the ongoing operation of
history!
The user must have access rights for the
specified path, otherwise the file will not
be written.
The imported data are stored with the OK button.
This function of the PC tool allows you to
record and monitor the measured values of all
connected digital and analog measurement
points.
Note:
Missing or incorrect settings will have
a serious impact on the monitoring!
E.g.
- If the files 1, 2 and 3 are in the directory, the
PC tool software will start saving the
file with number 4.
- If the files 1, 3, and 6 are in the directory, the
file 2 will be written first, then 4, then 5, 7, 8,
9, etc., so that the gaps are filled! This has the
disadvantage that it will not be represented in
chronological order (e.g. with Excel Diagram).
Each automatically saved file contains as many
records as indicated in the field Number of
datasets saved per file.

History of the data logger
(Continued)
Start:
This menu item or button starts the history.
The following information appears at the very
bottom of the main window in the status bar.
- A green LED changing to red from time to time.
The green LED indicates that history is enabled.
If the LED changes to red, a record is just being
written into the file.
- Two numbers separated by a minus.
The first number represents the number of records in the current file with digital measuring
points (DP).
The second number represents the number
of records in the current file with analog
measuring points (AP).
- The specified path where the files are stored.
Pause:
This menu item or button interrupts the
recording. It is useful if you want to view the file
in between. If you resume the recording with the
start button, the current file will continue to be
written.
Attention:
If the LED flashes green-red, but the
numbers remain at 0, the software
tries to write the history files, but fails.
In this case, please check access rights
to the path or run the PC tool as an
administrator.
Attention:
If the file was opened, please pay
attention to closing the file before
restarting.
Stop:
This menu item or button stops the recording.
A new file is started after restarting.
Structure of Files:
Regardless of whether only digital or only analog
measuring points or both are recorded, the files
are of an identical structure.
- The first column contains the date and time
with hours, minutes and seconds.
- The second column indicates the measurement
values as current and / or average values.
- From the third column on, the measured values
are displayed. 96 entries for digital measuring
points and 32 entries for the analog measured
values.
The measured values are displayed according
to the measuring range. If the system contains
mixed measurement points, the scaling of the
measured values may be different according to
the measuring range.
A minus instead of the measured value means
that the measurement points are not activated.
If there is an error at a measuring point, it is
shown in form of a hexadecimal error code.
E.g.: 0x8100  Underrange
