Relay (REL1 … REL3):
indirect contact monitoring
Maintenance requirement:
constant light of red front-LED and REL3-contakt opened
A maintenance requirement report always occurs via the relay contact of the REL3, which is operated in zero
signal current principle. The relay contact closed in the status offers the option of series connection with further
REL-3 pins of other devices and thus common alarm monitoring. The relays REL-1 and REL-2 and the
transistor outputs DO1 and DO2 can be involved in the alarm signalling.
