Fault Function
If there is a voltage drop (GV-value below 0,1V) from the sensor there is a fault situation. During the
first four hours the green LED will be deactivated,
and the other LED’s will flash. Alarm relay C will
change state. After four hours the LED “Alarm B” will light (other LED’s will
be deactivated) and relay
“Alarm B” will also change state.

Fail Safe
Relays are in normal mode energized and will change state if power failure or if a fault situation
occurs.
