A quick and simple guide to troubleshooting your solenoid valve. The possible causes for your burnt out/cooked coil are listed below alongside instructions of how to resolve the issue.
Wrong voltage applied
- Check coil marked voltage is correct for the voltage being supplied.
- Change the solenoid coil for the correct one.
- Check wiring and wiring diagram.
- Check voltage tolerance, typically +/- 10% or 15%.
Coil short circuit
- Check remaining installation for short circuit.
- Check electrical connections at coil and DIN connector.
- Check moisture in coil, replace as required. Check IP ingress protection is in accordance to requirements.
Coil armature slow
- Isolate the electrical supply
- Drain the system
- Carefully remove the armature assembly, which will have small internal parts and replace.
- Install a well ventilated guard to protect the solenoid valve armature.
- Clean armature assembly or replace.
- Install a filter, such as our RPE filter assembly to remove debris in media and/or try to mount solenoid valve with armature vertical so any small particle debris will tend to gravitate down and flush out.
Media temperature too high
- Check media temperature is correct for the solenoid valve specification.
- Move solenoid valve away from the heat source into a cooler area or increase ventilation
