Abstract
A method of ensuring safety in operation of a coating apparatus includes the steps of measuring an instant value of a spray current, and regulating the spray current so that the spray current does not exceed a predetermined spray current limiting value by adjusting the high voltage applied to an electrode of the apparatus based on the measured instant value of the spray current. The spray current is directly measured in a return path of electrical current from the object to a regulating circuit of the apparatus.
