Status
No error. Operating
voltage/sensor supply
applied
Operating voltage/sensor
supply outside the
tolerance range
Internal fuse for the
operating voltage/sensor
supply has responded.
The operating voltage/
sensor supply is not
applied
Status
No error. Load voltage
applied

supply or additional supply
outside the tolerance
range
Meaning / error handling
–
Eliminate undervoltage
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
Check the operating voltage
connection of the electronics
Meaning / error handling
None
