In a drive circuit in which a plurality of drive motors are connected to a power source through a protective device which trips when the flow of current is excessive, provision is made to detect which circuit or circuits were active at the time of the failure. A microprocessor is provided to both control the activation of each of the various circuits and to also sense which circuits were active at the time of the failure. Appropriate signals are sent from the microprocessor to a user interface so that proper diagnostic and repair action can be taken. |
