When the pressure switch is correctly connected and using the sample code, it will not shut the compressor off until the high side pressure reaches about 125 psi. It is possible that you have a leak if your system cannot reach 125 psi. That leak can come from a badly cut pneumatic tubing, loose fittings, a improperly connected valve, a defective pressure vent valve or from an uncalibrated pressure relief valve on the compressor. Soapy water wiped at each pneumatic joint will quickly find a leak.
