7.3 General alarm relay
The controller manages a configurable alarm relay. For each alarm there is a parameter which
selects whether that alarm must be signalled on the alarm relay. Several alarms can be addressed to
the relay.
Via the relevant parameter (PH61) it is possible to establish the polarity (NO, or NC) of the alarm
relay.
