Older big Sullair will NOT kick out at normal cut out
We have a big Sullair electric compressor that builds air right on past 160 p.s.i.
The adjustments on the Allen-Bradley control do not control.
I have metered the control and see that the voltage to the normally open solenoid valve is normal and as I watch, the voltage does shut off at the desired setting allowing the valve to be open again.
I have had the solenoid valve off and apart and it looks okay and the coil does actuate the valve.
I'm thinking the valve may be bad and I'm missing the problem.
