Assigning the alarm messages to the relays

The "on" setting assigns an alarm message to the respective relay. The LED indication is directly assigned to the
alarm message and is not related to the relays.
In the event of an unsymmetrical insulation fault, only the alarm message corresponding to the assigned
conductor (L1/+ or L2/–) will be displayed.
