Status
No fault Operating voltage/
sensor supply applied
Operating voltage/sensor
supply outside tolerance
range
Internal fuse of the operat
ing voltage/sensor supply
has responded
Operating voltage/sensor
supply not applied
Status
No fault Load voltage
applied
Load voltage at system
supply or additional supply
outside the tolerance
range
Meaning/fault treatment
Eliminate undervoltage
1. Eliminate short circuit/overload
on module
2. Depends on the parameterisation
of the module (module para
meters):
The sensor supply voltage will
·
be switched on again automati
cally when the short circuit is
eliminated (default)
Power off/on necessary
·
Check operating voltage connection
of the electronics
Meaning/fault treatment
None
Eliminate undervoltage
