Technical Overview
Links
The CL-CO-RFG361 is a single channel gas leak alarm sys-
tem. It is designed for the detection of gas leaks in spaces
such as boiler plant rooms, workshops and other industrial
gas installations, to provide safety alarm and shutdown
facilities on detection of gas leakage.
Installation
1. The GL-CO-RFG361 should only be installed by a compe-
tent, suitably trained technician, experienced in installa-
tion with hazardous voltages. (>50Vac & <1000Vac or
>75Vdc & 1500Vdc)
2. Ensure that all power is disconnected before carrying out
any work on the GL-CO-RFG361.
3. Maximum cable is 2.5mm², care must be taken not to
over tighten terminals.
4. Separate the base from the cover.
5. If DIN rail mounting clip onto the DIN rail.
6. Make connections as required (see page 4 for examples)
and links as appropriate (see below).
NB It is advised that no more than 2 cables be inserted
into a single terminal. Use external junction boxes if
necessary.
7. Replace the cover on the base using the 2 screws pro-
vided, if panel mounting fix to panel door, using the
panel mounting kit.
Operational Relay Output:
When in alarm:
F2 - F3 linked
1 - 3 closes, 2 - 3 opens
F2 - F3 unlinked
1 - 3 opens, 2 - 3 closes
Latching alarm and Reset:
F3 - F4 linked:
Alarm ceases when the gas concentration falls below the
threshold level and the ALARM LED blinks slowly. Press the
RESET button to clear the LED status.
F3 - F4 unlinked:
Alarm continues even when the gas concentration falls be-
low the threshold level. To deactivate press the RESET but-
ton for at least 5 seconds.
Link functions:
M - F1
No link = Internal buzzer enabled
Linked = Internal buzzer disabled
F2 - F3
No link = Relay normally energised when no gas present
Linked = Relay normally de-energised when no gas present
F3 - F4
No link = Relay with latching alarm
Linked = Relay with non-latching alarm
