Status
No fault, operating voltage/
sensor supply applied
Operating voltage/sensor
supply outside the
tolerance range
The operating voltage/
sensor supply is not
applied
Status
No fault, load voltage
applied
Load voltage outside
tolerance range
Error handling
1. Eliminate short circuit/overload
2. Dependent on the parameterisation:
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
Error handling
None
1. Eliminate undervoltage
2. Dependent on the parameterisation:
The load voltage supply will be
·
switched on again automatically
after the undervoltage has been
eliminated (default)
Power Off/On is necessary
