1.6.1 Error messages of the pneumatic interfaces
Error number Description
5 Fault in load voltage for valves
Load voltage for valves (V
or too low.
(see Parameters "Monitoring the CPX
module – Monitoring V
11 Fault short circuit at valve
Short circuit/overload at the valve
(see "Parameters" "Monitoring the
CPX module – monitoring short circuit
at valve")
13 Fault wire fracture
Monitoring residual current of valve
solenoid coils (open load, only active
with 0-signal).
(see Parameters "Monitoring wire
fracture channel x")

Tolerance range of the load voltage supply V
2)
Number of faulty channel: see module diagnostic data.

Specific faults of the pneumatic interfaces are registered or
suppressed depending on the module parametrizing.
The faults are shown on-the-spot by means of the Error LED
and, if necessary, can be evaluated with the handheld.
Depending on the module parametrization the faults are reg-
istered by the field bus node, where they can be evaluated
according to the field bus protocol used.
A pneumatic interface can register the following standard
faults:

Error treatment
Check the load voltage
•
Check the valves, whether they are
•
fitted correctly and electrical con-
nections
If necessary, replace the valve
•
