Error detection contact AMP 120 and AMP 240
On the rear side of the devices there is an error detection terminal as dry changeover contact. If
either mains or battery power is missing, for instance if a fuse is blown, the SUPPL Y VOLTAGE
MONITORING relay contact will switch.
As one of the energy sources is not present, the COMMON terminal is connected to CLOSED ON
VOLTAGE ERROR. The OPEN ON VOLTAGE ERROR terminal is open in this case.
If both voltages are present, the COMMON terminal is connected to OPEN ON VOL TAGE ERROR
and the CLOSED ON VOLTAGE ERROR terminal is disconnected.
The contacts load capacity is 30V DC / 1 Amperes.
