operating voltage/sensor
supply has responded 1. Eliminate short circuit/overload on
module side
2. Depends on the parameterisation
of the module (module parameter):
·
The sensor supply voltage will
be switched on again
automati
cally when the short circuit has
been eliminated (default)
·
Power OFF/ON is necessary
LED is off
