5.2.4. SHORT_CIRCUIT_CURRENT alarm
The SHORT_CIRCUIT_CURRENT alarm trips when
the peak current on the load exceeds the maximum
valueallowed during the softstart ramp or at first
power-on (with the softstart ramp disabled).
If configured (parameter Fr.n other than zero), the
device restarts automatically in softstart for a
maximum Fr.n number of attempts, beyond which it
remains off awaiting manual reset via the front key or
via the command via serial or IO-Link.
The number of trips to switch off the overcurrent
protection device is shown in FO.c1 and FO.c2.
FO.c1 and FO.c2 are updated 30 s after a successful
restart.
The FO.c1 count can be reset by command via serial
or IO-Link.
The SHORT_CIRCUIT_CURRENT alarm is disabled
for IR lamps (see parameter PS.E).
