This circuit monitors two pulsed outputs from the high voltage drive section of a xerographic copier, to indicate failure of either section, so that the field-replaceable high voltage unit can be effectively isolated from the drive circuitry. The output signal of the circuit is implemented using the existing microcontroller.
