8. First time switch on (Commissioning)
Note: Calibration is mandatory before the detector can be used for gas monitoring. Refer to chapter 9.1
Calibration for the proper procedure.
1. Remove the transmitter housing cover and detach the display unit by lifting the semi- circular
handle and pulling the assembly directly away from the termination module (without twisting it)
2. Configure the detector's analogue output signal configuration for Current SINK or Current
SOURCE operation using the selector switch located on the back of the display module. The
default setting is Current SOURCE.
3. Check that all electrical connections are terminated correctly as per chapter 5.
4. Switch On the external power supply to the transmitter at the safe area gas detection controller
(or PLC).
5. Using a Digital Multi Meter (DMM), check the Supply Voltage at the terminals 1 (24 V) and
2 (0 V), this should be a minimum supply voltage of 12 Vdc or 16 Vdc depending on the
transmitter version (Maximum supply voltage is 32 Vdc)
6. Switch Off the external power to the detector.
7. Refit the Display Module and Cover.
Note: Ensure that none of the wires in the terminal area cause an obstruction when refitting the Display
Module. Ensure that the socket on the Display Module is fully engaged in the Display Module Connector
on the Terminal Module.
WARNING
The following procedure requires the Transmitter Cover to be removed while carrying out
supply voltage checks. Therefore, the appropriate permits to work should be sought in
preparation.
Prior to carrying out any HOT WORK ensure local and site procedures are followed.
Ensure that the associated control panel output actuation is inhibited so as to prevent false
alarms.
CAUTION
The following procedure should be followed carefully and only performed by suitably
trained personnel.
