Abstract
Abstract Plural indicator circuits which correspond and are connected to control circuits of a control panel are activated and deactivated as the control panel proceeds through its control sequence, and special interconnected control circuits within the unit successively activate and de-activate the indicator circuits to show the control panel circuit which failed.
