Abstract

PURPOSE: To make easy the failure diagnosis of unit and its repair, and to prevent unnecessary power consumption, by recording the location of failure production and the content of failure, and interrupting the drive power supply of failure detector.
CONSTITUTION: When a failure is taken place to the power supply unit 1 of the central processing unit V1, alarm signal is output from the terminal 1a of the failure detection unit C1. On the other hand, the address signal corresponding to the power supply units 1W4 is input to the multiplexer 9 from the power unit address circuit 12. Further, when the address signal designates the power supply unit 1, the alarm signal is input to the alarm signal processing circuit 14 via the multiplexers 9, 13. Then, based on the alarm signal and address signal, the content of failure and the failure production unit are printed with the printer P. Further, the power supply cut-off indication circuit 16 is controlled to interrupt the output of the drive power supply 5.
