Abstract
Systems, methods, and computer-readable medium containing instructions for operating a conveyor. One method includes receiving, by a controller, a signal from each of a plurality of substations. Each of the plurality of substations provides power to a motor drive unit driving a conveyor belt of the conveyor. The signal received by the controller indicates whether an isolation switch associated with each substation has been manually operated. The method also includes, when the signal received from one of the plurality of substations indicates that the isolation switch associated with the one of the plurality of substations has been manually operated, transmitting, by the controller, a signal to each of the plurality of substations, the signal instructing each of the plurality of substations to isolate the motor drive unit from a power source.
