Abstract
PURPOSE:To improve the reliability of the whole of the system, by making it possible to perform the switching control of the system automatically or manually. CONSTITUTION:An automatic switching control function is controlled by switching supervisory control circuit 11A and 12A and a signal from a device state switching signal line 18; and if a fault occurs in a current device 11, the circuit 11 reports the fault to a maintenance supervising device 13 to switch a stand-by device 12 to the operation state. A manual switching control function is controlled by circuits 11A and 12A, the signal from the device state switching signal line 18, and a manual operation switch. Since the manual control is adopted, the reliabilty of the whole of the system and the facility for maintenance are improved.
