Error description
Cause
Remedy
Valve does not respond.
Operating voltage not applied.
Check the operating voltage
connection.
No setpoint voltage.
Check the controller and con-
nection.
Working temperature is too
high. Valve is in temperature
shut-off.
Switch off the valve, let it cool
down and restart.
Reduce ambient temperature
and / or temperature of
medium.
Valve normally open:
The working pressure at (2) falls
to the level at (3) (ambient pres-
sure or vacuum).
Cable break setpoint input
Check connection to setpoint
generator.
Replace supply cable.
Valve normally closed:
The working pressure at (2)
deviates upwards or down-
wards from the setpoint value
(working pressure is neither
pressurised nor exhausted).
Cable break setpoint input
Check connection to setpoint
generator.
Replace supply cable.
Setpoint value not reached.
Input pressure at (1) is too low.
Increase input pressure at (1).
Maintain permissible maximum
operating pressure

Disassembly
1. Specify setpoint value 0 bar (0 MPa).
2. Switch off compressed air supply.
3. Switch off operating voltage.
4. Remove electrical connecting cables.
5. Remove compressed air lines.
6. Dismantle the product.
