Menu “setup->relay”
Setup for the relays:
„normally open
normally closed“ - this selects the relay inversion. If one chooses „normally
open“, the relay will be open in inactive state and it will close on activation. “normally closed”
inverts this behaviour.
„automatic reset
manual reset“ - If a relay is set to “manual reset”, it will stay activated once it
has been triggered by an alarm or trip, even if the alarm or trip is inactive again (hold state). If
“automatic reset” is used, the relay will fall back to inactive state automatically once the activating
alarms or trips have become inactive again.
„DI disabled
DI enabled“ – If adjusted “DI enabled” a relay can be blocked via the digital input
to avoid accidentally trips
