Possible faults on solenoid valves

9.3

Observation

Possible cause

Anchor does not make con-
tact.



Connection voltage is interrupted or is insufficient.



Solenoid defective.



Anchor blocked in dirty tube space. If the anchor does not reach the

stroke end position, when the AC coil is excited this will soon result in
coil failure (due to thermal overload).



Rated voltage different from coil voltage.

Valve does not close.



Anchor blocked!



Rated voltage still present

Valve does not open.



Rated voltage not present.



Solenoid defective.



Rated voltage different from coil voltage.
