Relay signaling assignment "r1" and "r2" and LED assignment
When set to "on", the individual messages/alarms are assigned or mapped to
each relay. The LED display is directly associated with the messages and is not
related to the relay. In the event of an unsymmetrical insulation fault, only the
message corresponding to the assigned conductor (L1/+ or L2/-) will be dis-
played.
