Error LED
The red error LED indicates the following faults of the pneu-
matic interface depending on the parametrization.
Status
Faultless operation
Fault in load voltage for valves
Load voltage for valves (V
VAL
missing or too low
Fault short circuit at valve
Short circuit/overload at the valve
Fault wire fracture
Monitoring residual current of valve
solenoid coils (open load, only
active with 0-signal)
The fault indicated by the red error LED is transmitted by the
pneumatic interface to the field bus node (unless parame-
trized 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).
