摘要： A diagnostic apparatus for a powder coating material pump includes a detector that uses pressure or flow to detect a fault in the pump, the diagnostic apparatus being external the pump, internal the pump or a combination of external and internal the pump. Another diagnostic device is provided for a powder coating material pump, and includes a light source in close proximity to the pump, the light source having an on condition and an off condition wherein one or both of the on condition and off condition provides information about the pump performance. An exemplary pump is a dense phase powder coating material pump.

摘要： An apparatus for use in electrostatically applying coating material to an object includes a nozzle (21) which directs a flow of coating material toward the object (28). A power supply unit (9) provides an electric field to electrostatically charge the coating material. Control circuitry (16) is provided to monitor the operating efficiency of the power supply unit (9) and to provide an output signal when there is an impending failure of the power supply unit (9). The control circuitry monitors the relationship between an input current to the power supply unit (9) and an output current from the power supply unit (9). When the relationship between the input current to the power supply unit (9) and the output current from the power supply unit (9) 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.
