A +24 V DC continuous signal leads to a permanent bridging of the
monitoring, i�e� the same state as during the start-up delay is indicated�
When the voltage is no longer applied and the set start-up delay has
elapsed, monitoring starts�
Note on F���-xN:
The +24 V DC signal voltage required for the reset inputs is not available to
the F���-xN� This must be taken from an external voltage source� The reference
point (GND) of the external power supply must be connected to terminal 1 of the
monitor; otherwise no switching operation is possible�
