    Hi
    My machine has stopped
    Fault reads: cylinder guard unit 1 open.
    However the guard is in actual fact closed and the switch +1 s90 is ok.
    voltage at DIPM 220 +91A32 plug x10 pin 10 is +14v0lts
    voltage at DIPM 220 +91A32 plug x20 pin 90 is +24 volts
    The machine will only start to run when the voltage at pin 10 drops down mysteriously to zero.
    Can someone explain to me how I can fix this problem?

    Ralph

    Hi sir
    I hope you are well
    Try to adjust the switch, and clean the contacts with special cleaner contacts
    by other sides, Tight very well the wires, and test it for continuity, (repair or replace),see
    if there are Voltages according with the schematic diagrams.
    Let me know, any question or doubt about.
    Regards
