Step
Action: Testing the electrical supply
Measure the idling voltage (without connections).
4.
Replace or repair the electrical supply if it is defective.
Measure the incoming idling voltage on the supply cable at the device.
To do so, switch off the electrical supply and disconnect the supply cable plug from
the board to the GasLab Q2 connection box. Switch on the electrical supply again
5.
and measure the voltage in the plug. If there is no voltage, or if it is significantly lower
than the idling voltage, replace the cable after disconnecting it from the power
supply.
If the problem has not been rectified after completing steps 1 – 5, the error is inside
the device. Please contact Honeywell to check the internal fuse. The housing must be
6.
opened to replace it and, for safety reasons, this should only be done by service
personnel or appropriately trained personnel.
the interactive screen will also be dark and the status LEDs will be off.
The components involved in the measurement are not live. Notify Honeywell.
Rectification of the errors under point 6 (communication error)
The following action can be taken if an error occurs in the data communication If you have multiple
devices on the bus, you must take the slowest subscriber into account when selecting the operating
mode. If the bus communication is not working, it may be the case that the device has been
parameterized to too high an operating mode.
Step
Action: Checking the communication links
If changes have been made to the parameter set, you can reverse them. Use the lates saved

1.
settings (importing data)
Check the communication cables for signs of damage.
2.
Check the "terminal to terminal" connection for each core.
Test the function of the digital outputs after switching off the device.
The plugs of communication cables have been disconnected in the connection box.
Use a measurement device to test whether there is a connection between the switch signal

terminals and the return cable.
Except for output DO_1, the normally closed contact, no connections are permitted to
be made.
