CAP/DR FAULT

The door switches and capacitor pressure switches (which monitor capacitor case pressure) are all wired in series, along with the E-Stop circuit of the system. If any of these switches are opened this fault will be activated. E-Stop protected 120VAC - wires 103(line) and 100(neutral) - will drop out of the system until the fault is corrected.

If a capacitor pressure switch trips, the capacitor is faulty and will need to be replaced. You can identify the capacitor using a multimeter to find the break in the AC voltage of this circuit.
