Relay Parameters

8.6.1 Relay Mode

The fault relay is listed as relay 3 and can be registered here as an
additional alarm relay. This registration has no influence on the
function as fault relay.
The relay switches off in addition when the assigned alarm is
active.

8.6.2 Relay Operation Mode

Relay 3:
The parameter setting "Energized" cannot be changed.
The terms energized / de-energized come from the terms "energized / de-energized to trip" principle used for
safety circuits. The terms refer to the activation of the relay coil, not to the relay contacts (as they are executed
as changeover contacts and available in both principles).
The LEDs at the modules show the state in analogy. (LED off -> relay coil current-free)
