PURPOSE:To simplify the configuration of a control system by applying the output pulse of a flicker circuit having two timers to a flip-flop to sequentially start a plurality of units. CONSTITUTION:When an operation switch 2 is pressed, a start/stop relay 4 is energized to alternately excite timers 11, 12 which form a flicker circuit. A pulse output relay 13 is turned ON and OFF to match the ON and OFF timings of a pulse contact 12b. When the pulse output relay 13 first becomes ON, a starting relay 14A is energized. When the pulse output relay 13 is turned OFF, a pulse OFF confirmation relay 15A is excited, and an electromagnetic contactor 7A is excited to start a unit No.A. When the relay 13 second becomes ON, the starting relay 14B of a unit No.B is energized. Then, unit Nos. B-N are sequentially started. |
