If an empty fault mask (P1 is not monitored) is set or is to be set, P1-LED flashes at a
frequency of 2.5 Hz.
Simultaneously with the fault mask, the monitoring of the connected power supply is set. The
existence of the two power supply units is only monitored if both power supplies are
connected during saving the fault mask.
The failure of the link on the monitored port P1 or of one of the monitored power supplies is
indicated by the illuminated red error LED. The signaling contact is opened simultaneously.
Note
The factory default is no port monitoring of port P1 but monitoring of the power supply
L1+/M1. If necessary, error LED and signaling contact have to be cleared by pressing the
button for an appropriate period or the feeding point has to be changed when connecting
only one power supply to L2+/M2.
The setting remains after turning off/on.
