PROBLEM TO BE SOLVED: To quickly and easily perform a restoring process such as replacement of components, while a short failure point is identified across the entire system. SOLUTION: A system comprises a power source circuit 110, a control part 112, a failure point display part 114, and loads 120-1 to 120-N. The power source circuit 110 and all the loads 120-1 to 120-N are provided with separate overcurrent detection parts 130A and 130B. The control part 112, when receives a detection signal from the overcurrent detection parts 130A and 130B, commands the power source circuit 110 to stop (turn off) feeding, while it commands the failure point display part 114 to output an alarm by specifying the failure point. The failure point display part 114 displays on a panel a place of a short mode failure in the power source circuit 110 or loads 120-1 to 120-N, while it issues an abnormal report with an alarm buzzer, etc. COPYRIGHT: (C)2004,JPO
