ABSTRACT:
An apparatus for use in electrostatically applying coating material to an object includes a nozzle which directs a flow of coating material toward the object. A power supply unit provides an electric field to electrostatically charge the coating material. Control circuitry is provided to monitor the operating efficiency of the power supply unit and to provide an output signal when there is an impending failure of the power supply unit. The control circuitry monitors the relationship between an input current to the power supply unit and an output current from the power supply unit. When the relationship between the input current to the power supply unit and the output current from the power supply unit is outside of a predetermined range, the control circuitry is effective to provide an output signal to notify an operator that there is an impending power supply unit failure.
