Sensors
The positioning of sensors depends upon the type of gas to be
monitored and its density with respect to air. See G973
Heavier than air gases
(Carbon Dioxide, Hydrogen Sulphide) –
locate at 15 to 20 cm from floor level.
Lighter than air gases
(Ammonia, Hydrogen Cyanide) –
locate at 5 to 10cm from the ceiling.
All equipment should be mounted away from direct heat and in
accordance with its IP rating.
Cell replacement / transmitter calibration
New sensors are supplied ready to connect to the system with all
jumpers inserted. This procedure shows how to recalibrate as part of
a routine maintenance or cell replacement.
1. If bench testing the PCB see section E3
2. Using a digital mV meter measure across test pins TP2/3 and
adjust Zero pot RV2 (course adjust) until LED D9 goes green for
4mA (zero) = 4mV
3. Apply a known test gas to the sensor (e.g. 100ppm CO for
200ppm range) for 1 minute at a flow rate of 1 litre to give a
12mA = 12mV across test pins TP2/3, adjust gain pot RV4 for
correct mV reading.
4. For display and relay set up see sections B or E

Setting/adjusting using display board
push buttons or single magnet
On power up the unit will be inhibited for a 120 second warm
up period displayed as a countdown on the display (this may
be overridden by pressing 1).
Carry out procedure A. To access the menu press 2 (equipment
SN will be displayed) followed by the entry code 231, pressing
1 or 3 will allow travel through the menu and adjustment of
settings, pressing 2 enables access into the selected menu field
and on completion pressing 2 will confirm your selection.
Menu
1. Exit
2. Inhibit – relays and 4~20mA signal output to 2mA
3. Address – CANbus sensor address (Combi)
4. Zero/span (fine adjust)
5. Alarm levels set – valve/direction (rising/falling)
6. Exit
7. Delay to alarm (relays) 0~255s
8. Relay off delay 0~255s
Default setting 0 seconds
9. Normally energised/de-energised relays

Note: Set LED status jumpers on the display PCB
(when used) to match relay settings.
