    950 PMC Alarm:
    This alarm is issued if a fault is detected in the PMC.
    The probable causes include an I/O link communication error and a
    defective PMC control circuit
    If alarm 950 is issued, displaying “PC050” on the screen, an I/O link
    communication error may have occurred.
    Most likely a cabling problem.
    Check all cables to/from toolchange into control.
