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.
