PS (power system)  power sensor/logic supply
LED (green) Process Status Fault treatment
LED lights up
ON
OFF
No error. Operating volt
age/sensor supply applied

LED flashes
ON
OFF
Operating voltage/sensor
supply outside the
tolerance range
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
LED is off
ON
OFF
The operating voltage/
sensor supply is not
applied
Check the operating voltage
connection of the electronics
PL (Power Load)  power load supply (outputs/valves)
LED (green) Process Status Fault treatment
LED lights up
ON
OFF
No error. Load voltage
applied
None
LED flashes
ON
OFF
Load voltage outside the
tolerance range.
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
