Error/fault
Possible cause
Troubleshooting measure
-Output flow too low or not proportional
- Connection cross section too small
-Check and enlarge if necessary
-no control / maximum flow only
- Supply voltage missing/too low
- Check voltage and ensure if necessary , check for
current limitation
- no output flow
- no setpoint is present
-no supply pressure
-pneumatic connections clogged
- pneumatic connection
- measure the input signals
- check
- check
- check according to the book
- Fluctuations in the output flow
- Fluctuations in supply pressure
- Diagnosis of the pressure supply
- No reaction of the output flow when the setpoint value
is changed
- Valve mechanics dirty / damaged
- Check filtering and send in device for maintenance
- Output flow is reached only sluggishly
- Use of compressed air that has not been cleaned or
lubricated
- Dirt in the valve causes friction
- use unlubricated compressed air and install oil filter
or suitable FRL unit
-Check filter
- Abrupt change of the flow
- Disturbances in the input signal or in the supply
- Insufficient shielding of the setpoint signal or the ground
connection
- Installation Improve / Shield
- Improve ground wiring
- Flow rate at setpoint in middle position too high / not
as expected
- Faulty mass connection when using the diffential voltage
input.
- Internal leakage due to contamination
- Correct the wiring of the system
- Have valve serviced
