Status
No fault Operating voltage/
sensor supply applied
Operating voltage/sensor
supply outside the toler
ance range
The operating voltage/sen
sor supply is not applied
Status
No fault Load voltage
applied
Load voltage outside the
tolerance range.
Fault treatment
1. Eliminate short circuit/overload
2. Depending on the parametrizing:
The sensor supply voltage will be
·
switched on again automatically
when the short circuit has been
eliminated (default)
Power Off/On is necessary
·
Check the operating voltage connec
tion of the electronics
Fault treatment
None
1. Eliminate undervoltage
2. Depending on the parametrizing:
The load voltage supply will be
·
switched on again automatically
when the undervoltage has been
eliminated (default)
Power Off/On is necessary
