PS (power system) – power sensor/logic supply
LED (green) Sequence Status Meaning / error handling
LED lights up
ON
OFF
No error. Operating
voltage/sensor supply
applied
–
LED flashes
ON
OFF
Operating voltage/sensor
supply outside the
tolerance range
Eliminate undervoltage
ON
OFF
Internal fuse for the
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 automatically
after the short circuit has been
eliminated (default)
• Power Off/On is necessary
LED is off
ON
OFF
The operating voltage/
sensor supply is not
applied
