Design a control for four electric motors. Motors 1, 2, and 3are to be controlled separately. When any one of the three starts,motor 4 is to start. Motor 4 can also be started independently ofthe others. If any motor reaches an overload condition, it willshut down all of the motors. In addition, there is to be a masterstart-stop switch (momentary) to make it possible to manually shutdown all operating motors at once. The master start switchenergizes the control circuit after which any particular motors isstarted individually. Report your circuit in ladder diagramform.
