An automatic system for controlling a plurality of motors includes motor starting circuitry and motor stopping circuitry that serves to sequentially start and stop the motors in the same cyclic order. The starting circuitry has a sensing component for sensing the presence and absence of a condition that reflects the need for starting the motor and a master starting control component which develops two different states that are used in controlling the circuits of the starting circuitry. The control circuits include a plurality of motor starting circuits for starting the respective motors and a plurality of conditioning circuits that normally respond to one of the developed states for conditioning the starting circuits for response sequentially to the other of the developed states and in a cyclic order for starting the motors. The stopping circuitry has a sensing component for sensing the presence and absence of yet another condition that reflects the need for stopping the motor and a master stopping control component which develops two different states that are used in controlling the circuits of the stopping circuitry. The control circuits of the stopping circuitry include a plurality of motor stopping circuits and stopping circuit conditioning circuits which normally respond to the development of one of the states to condition the starting circuits for sequential response to the development of the other of the states and in the same cyclic order used for starting the motors. Timing circuits are described for sequentially stopping and/or starting the motors when a continuing stop or start demand arises and for causing the sequential response in each of the starting and stopping circuitries.
