Relays | Operating Manual GW 702 | 21
Instead of the measured value display, the display indicates "Erase Alarm, press key
".
With key
the alarm is acknowledged manually and the relay is switched.
NOTE!
Through the manual acknowledgement only the relay is switched. The alarm message is still displayed until
the cause of alarm has been eliminated.

Direction
You determine with the direction, whether relay 3 is normally open (make contact, N.O.) and closes in case
of an alarm or vice versa (break contact, N.C.). In the second case the relay is held active in its normal posi-
tion. This way an alarm is raised even during a power failure.
