Fault diagnosis with the LED PL
The green LED PL (Power Load") indicates faults in the load
voltage supply.
Operating status
Load voltage for valves/outputs
not applied
Load voltage of CP valves of the
CPV Direct . 20.4 V
Load voltage of the CP valves/
outputs in the CPI extension string
. 20.4 V
Load voltage for CP valves/
outputs is applied
Load voltage faults are always displayed with the LED PL
(irrespective of the diagnostic mode set).
If the device−related diagnosis is activated, faults will also be
sent to the master PLC via the field bus.
