Fault LED
The red fault LED of these pneumatic interfaces indicates
the faults of the pneumatic interface depending on the
parameterization.
Status
Faultless operation
Fault in load voltage for valves
Load voltage for the valves (V
missing or too low.
Fault short circuit at valve
Short circuit/overload at valve
Wire fracture fault
Monitoring the residual current of
the valve solenoid coils (open load,
only active with 0−signal).
Only relevant for CPA or VTSA pneu
matics.
The fault indicated by the red fault LED is transmitted by the
pneumatic interface to the field bus node (unless parameter
ized otherwise).
Status LEDs of the valve solenoid coils
The yellow status LEDs on the valve solenoid coils indicate
the status of the relevant output (see appropriate pneumatics
manual).
