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 section 6.
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 (24V)
and 2 (0V), this should be a minimum supply voltage of 12Vdc (Maximum supply
voltage is 32V DC)
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.
8.
Switch On
external power to the detector.
9. All the display icons/text/numbers are displayed for 3 seconds.
10. A start up sequence will then be displayed, similar to the one shown in Diagram 15.
Note: Calibration is mandatory before the detector can be used for gas monitoring. Refer
to Section 10.1 Calibration for the proper procedure.
9 First time switch on (Commissioning)
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
