<p>PURPOSE:To average the operating times of a load by moving up or down the starting sequence of a plurality of loads at every starting. CONSTITUTION:When a command from a sequence instructing unit 12 is input to a central processing unit 12 by turning ON a control power source, the unit 12 stores a command and outputs a start sequence command based on the command to a control instructing circuit 10 through input/output controller 11. A sequence instructing unit 13 starts load 4a-4h in this order at the initial starting time, and starts in the order of 4b-4h, 4a when starting next. Thus, it is set to alter the sequence of the loads 4a-4h connected initially with a power source 1 at every starting. Thereby, the operating times of the loads are averaged.</p> |
