5.5 System Relay
The system relay is there to help you protect your transformer and alarm you should there be any issues with
the monitor itself or one of its connected sensors.
The system relay operates in Fail-Safe mode.
The relay has two possible default states:
Normally Closed
: When powering up, relay will remain de-energized, and in case of alarm, relay will
be energized.
Normally Open
: When powering up, relay will be energized, and in case of power outage, power
supply wiring cut-off the relay will be de-energized.
The following conditions will generate an alarm making the System Relay trigger:
Power failure
If a channel is at fault
If the internal software is at fault
If the system’s hardware is at fault
At power up the EasyGrid Base system relay is in alarm until all the actives sensors gives valid reading, it could
take up to 1minute (depending on the number of active channels) for the alarm condition to resume.
