In IPB (Isolated Pressurization bus Duct) PLC Control panel consists of relays, polyurethane and push in fittings. Due to very low air leaks at panel tubing, High-Low Pressure switches gives solenoid coils on-off commands frequently. so chattering of SOV'S increases.
It is difficult to sense the air leaks. My question is, How to check & resolve these small air leaks?
