Status
No error. Operating
voltage/sensor supply ap-
plied
Operating voltage/sensor
supply outside the toler-
ance range
Internal fuse for the oper-
ating voltage/sensor sup-
ply has responded
The operating voltage/
sensor supply is not ap-
plied
Status
No error. Load voltage ap-
plied
Load voltage at the system
supply or additional power
supply outside the toler-
ance range
Significance / error handling
–
Eliminate undervoltage
1. Eliminate short circuit/overload on
module side
2. Dependent on the parametrisation
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 connec-
tion of the electronics
Significance / error handling
None
Eliminate undervoltage
