Abstract
PURPOSE:To facilitate fault position detection by inputting a low-voltage current and a high-voltage voltage, an on-off signal, etc., to a device which receives electric power from a commercial power source and converts it into a high- voltage direct current, and computing and comparing a control mode with a basic control mode. CONSTITUTION:The arithmetic part 2 of a fault diagnosing means 5 inputs the low-voltage current and high-voltage voltage passed through a voltage divider from a connecting line 13, and also inputs the on-off signal and a signal of operation condition for current limitation, etc., from the relay contact 10 of the power unit. Then an arithmetic part 2 computes and compares the control mode with the basic control mode 3 to display a fault position on a display part 4. Consequently, the cause of an occurring fault is decided automatically and the fault position is easily detected.
