1.6.1 Fault messages of the pneumatic interfaces
Midi/Maxi, CPA or
VTSA pneumatics A pneumatic interface can register the following standard
faults:
Fault number Description Fault treatment
5 Fault in load voltage for valves
Load voltage for the valves (V
VAL
)
missing or too low.
1)
·
Check the load voltage
11 Fault short circuit at valve
2)
Short circuit/overload at the valve
·
Check that the valves are fitted
correctly and check the electrical
connections,
·
If necessary, replace the valve
13 Fault wire fracture
2)
Monitoring the residual current of the
valve solenoid coils (open load, only
active with 0−signal).
Only relevant for CPA or VTSA pneu
matics.
·
Check that the valves are fitted
correctly and check the electrical
connections,
·
If necessary, replace the valve
·
Correct any faulty parametrizing (e.g.
with reserved valve locations/blank
ing plates, see section 1.3)
1)
Tolerance range of the load voltage supply V
VAL
see Technical specifications" in the appendix.
2)
Number of the faulty channel: see module diagnostic data.
