PURPOSE:To provide a power supply fault notifying equipment capable of specifying a power supply unit where a fault occurs and notifying a controller of the fault. CONSTITUTION:A bus 41 for reporting fault information is provided to transmit and received power supply fault detecting information between a controller 30 and first to n-th function blocks 201 to 20n. Also at the first function block 201, provided are a first detection circuit 421 for creating power supply fault detection information by detecting power supply fault detection information transmitted from a first power supply unit 211, a bus interference circuit 431 for first fault information notification for sending the power supply fault information to a bus 41 for fault information notification, and a first battery backup circuit 441 for supplying backup voltage to the bus interference circuit 431 for first fault information notification and also to the first detection circuit 421 when a fault has occurred in the first power supply equipment 211. Same configuration is also for 2nd to n-th function blocks. |
