9.3. Relay working mode (relay 1 and 2)
The G031 allows for two different working modes:
self-lock control
latching control
Self-lock allows for the usual function of the relay where a command from the operator or the device to
change is needed. The G031 is set to latching mode by default.
With latching controls, the device will return to its normal status after a period of seconds determined by
the user. This is useful for output devices that don’t need or want to be on for a long time after they have
been turned on. For example alarm horns which might only need to be on for 12 seconds to alert the user.
To change between self-lock and latching control, the jumpers must be moved from one connection to
another. Carefully lift the jumper unit up vertically from the unit. Be very careful not to damage
components or the jumper pins. Ideally use tweezers to lift and lower jumpers into the correct place.
There are three pins on each set of jumpers, by moving the jumper over the pins on the set will give
either relay 1 or 2 different working methods. See the table below to help with changing jumpers
Self-lock control
– normal operation of relay on or off by
command from user or device timer
Latching control
- which means relay go back to normal status
after a period of action (3, 6, 9 or 12) Seconds.
When an alarm is triggered, the relay will stay locked ON until
the command “EXTRT” to reset alarm is sent (even if set to
latching mode).
