3.4 Diagnosis and parametrizing
Valve terminal type CPV..-GE-ASI-4-... supports the evalu­
ation of valve faults.
Any valve faults which occur will be registered as periph­
eral faults of the slave on the AS-Interface master.
The following valve faults are monitored:
– short circuit on the valve solenoid coil,
– wire fracture on the vale solenoid coil,
– valve does not switch (no movement of the plunger).
The diagnosis of the valve module can be deactivated via
the AS-Interface parameter port P3.

eral faults and displayed via the fault
