PURPOSE:To attain the restoration of a system in a short time after intervention of a manual operation by providing a manual-automatic operation reset condition decider to each detector and displaying an active/inactive state that is secured for the detector for reset to an automatic operation. CONSTITUTION:A relay connected to a step selected by a contact element of a stepping relay 7 receives an action command from the relay and is energized. Then the relay 7 is advanced by a step after a machine is actuated. In such a system controller, an automatic operation enable signal disappears to stop the drive of the machine if a manual operation is given during an automatic operation. When the automatic operation is started again, the machine is actuated according to the automatic action reset conditions shown by the pilot lamps 14 for automatic action reset conditions provided to detectors LS1, LS2... respectively. Then a step end state is obtained, and an automatic operation is started with push of an automatic start button switch after the automatic reset permission conditions are satisfied. |
