Alarm relays
The E9T control unit is provided of three independent relay contacts related to different emission alarm events
(Pre-Alarm, Alarm and Peak). Each time an alarm event is detected, the E9T switches the related relay contact in
order to trigger a load (external relay bobbin, lamp, buzzer, …) to remotely signal
the alarm.
The alarm event detections are fully configurable by on-screen menu. Please see the Commissioning section for
programming instructions.
All the relay contacts are voltage free. Please do-not exceed the maximum ratings of the on-board relay contacts
(please see terminals list for more details).
WARNING
It is not possibile to set or exchange the alarm
events in different relays positions than the
factory hardware configuration.
