    Having Problem with Pressure tank
    Although all press functions are working and the pressure tank is full, the
    compressor will not shut off. I opened the side panel and checked for leaks
    didn't find any but air is coming out of this air fitting pictured.
    I have the S24 cover switch off but can't determine what's wrong with it or
    how to go about fixing the problem. Faulty switch maybe?

    I don't have PM46-2 schematics, is it with CPTronics? usually in the pneumatics system, there is pressure sensor at feeder 15B14 (for CD102), which controls compressor. if air isn't leaky, possibly pressure sensor is defective.

    In the picture just to the left of the pencil (silver box with two springs showing).

    The valve pointed out in the pic was "clogged", (always open) so compressor wouldn't shut off so the sensors are ok,
    called Stan at Intermountain Press service he gave me the sf to turn it on and off and cleared right out.
    Also gave me instruction to take apart and clean. Problem solved.
