The PC tool software has to be started from the USB stick in order to use the available functions. on the USB stick there are binary data files that must be opened and/or changed - otherwise; no functions can be perfomed.
Connect your PC via a USB cable to the adapter that will automatically start to install the driver for the USB-RS485 adapter. A virtual COM port will be generated and this new port number is required later for configuring the PC tool Software.
Before the main window starts, the User rights are checked.
Attention:
If the PC Tool software is not started from the USB stick or if the rights check fails, the software will be closed again without showing the main window.

5 Establish the connection
When you click on the Connect button or on the
icon, the application opens the dialog for
setting the serial port.
Only those COM ports that are active on the PC are displayed. By clicking OK you can establish the connection to the COM port.
The display in the main window varies depending on the connected device.
Attention: If the authorization key (password) of the PC tool software differs from the authorization key of the connected device, a window will appear showing the input screen for plant ID (password). Password: 5468
The mask remains open until you have entered the correct plant ID and confirmed with OK or cancelled the input by using the cancel button. If you click cancel, the application will close!
If you enter the correct plant ID, the input screen will release the application and you can use all functions to the full extent.
5.1 Local bus
The Danfoss PC tool is connected via the COM port to the devices of the IO class (Basic, Premium and Heavy Duty).
A table with four lines appears in the middle of the main window. The first column of the table is a header column for each line. If the sensor is activated, the text “Sensor X” will appear in this column with X being a number between 1 and 4. Otherwise the header column remains empty.
The following columns give more information on the connected digital sensor head or the analog input.
Current and average value:
The current and average values of the connected digital sensor head or the analog input are displayed here. If the alarm thresholds are set to 0, the alarm evaluation will not take place and the readings will be displayed without alarm (usually backlighted in green).
If the threshold values are set greater than zero at the measuring point, a local alarm evaluation is active and the alarms are marked with different background colours. In addition, a tool tip displaying the active alarms will appear, if you click in the cell.

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.

5.2 Field Bus = Danfoss Controller (Continued)
5.2.1 Display of possible error messages
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).
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.

Deselect: The highlighted area is free again.
Acknowledge horn: Allows acknowledgment of
the horn with the address of the selected cell via the software interface.
Acknowledge latching: Allows acknowledgment of the latching selected address.
Relay test: Appears only if special mode is activated and relays are available. It has three osubmenus:
Alarm Test ON: Turns the relay into the alarm state. Alarm Test OFF: Turns the relay into the alarm- free state. Automatic: Turns the test function off. The relay returns to its normal function.
AO test: Appears only if special mode and the analog output are activated. Allows testing of the analog output by setting a fixed value.
- The left button sets the device, where the AO should be tested; usually the software takes over the setting automatically.
- The test value for the AO is set in the AO test value field in the range of 0 - 22 mA.
- The upper right button starts or stops the transmission of the test value.
- The bottom right button closes the window for the AO test; if the transfer of the test value is still active, it will be interrupted.
