14. 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 LEDs 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.

15. Fail Safe

Relays are in normal mode energized and will change state in case of power failure or a fault.
