<p>PROBLEM TO BE SOLVED: To enhance the reliability and safety of information processing, management and monitoring by outputting a closing command in conformity with a preset closing sequence to a power operated switch gear for switching a load circuit for the control with one line connected to a power supply bus and another line connected to a plurality of load circuits. SOLUTION: A power supply bus 11 is connected to a power supply circuit 10, and the power supply is branched. One side of switches 6, 7 and 8 are connected to a power supply bus 11, other side is connected in series to load circuits 2A, 3A and 4A respectively, and the load circuits 2A, 3A and 4A are power- operated for switching. And a controller 5 outputs closing commands 5a in accordance with a closing sequence predetermined for the switches 6, 7 and 8. Here, a CRT unit 2 is connected to the load circuit 2A, a printer unit 3 to the load circuit 3A, and a CPU unit 4 to the load circuit 4A. By doing this, the operation can be performed automatically in accordance with the predetermined switch closing sequence, so that any error in closing sequence can be prevented.</p> |
