PURPOSE:To separate trouble at the time of the switch-on of power supply by deciding whether a machine to be tested started normally or not when power is supplied to the machine to be tested. CONSTITUTION:A power supply ON/OFF checking equipment 4 is provided previously with a circuit 5 to receive a control signal to be outputted when the machine 1 to be tested starts normally, and it is decided whether the power supply to the machine 1 to be tested is to be switched on or to be switched off according to the presence of the control signal. The control signal reception circuit 5 provided in the power supply ON/OFF checking equipment receives the control signal, and simultaneously with the termination of reception, transfers a reception termination signal to a power supply control circuit 9. On the termination of the reception of the control signal, the power supply control circuit 9 stops supplying the power to the machine to be tested, and after predetermined stopping time elapses, it switches on the power supply to the machine 1 to be tested again. Thus, because it can be decided whether the machine 1 to be test started normally or not when a voltage is supplied to the machine 1 to be tested, the separation of the trouble at the time of the switch-on of the power supply comes possible. |
