PURPOSE: To make it possible to automatically restart by taking AND of a timer creating a constant timing output by the AND of power interruption detection, transmitted power detection, the outputs of OR circuits of overcurrent detection and undervoltage detection, and then by outputting a generator serious trouble reset signal. CONSTITUTION: During tripped state, a detected output occurs at either generator overcurrent detection means 3 or generator undervoltage detection means 4 and an output occurs at an OR circuit 6. At this point in time, an output has already occurred at a first AND circuit 5, and if an output occurs at the OR circuit 6 within a certain time limit after the occurrence of said output, then predetermined conditions during power receiving and interruption have been realized. In consequence, an output occurs at the second AND circuit 8 and becomes a generator serious trouble reset signal. By doing this, automatic reset can be realized and the restart of the generator can be performed. |
