速度になるまでの標準停止時間を記憶する記憶手
段と、原動機の回転数検出器からの入力信号に基
づき、停止信号が出力されてから原動機が実際に
停止、あるいは一定回転速度になるまでの時間を
求める計時手段と、この計時手段で求められた時
間と上記記憶手段に記憶された標準停止時間とを
比較し、比較結果に基づいて原動機の異常の有無
を判別する判別手段を備えたことを特徴とする原
動機停止時異常検出装置。 Based on the storage means that stores the standard stop time from when a stop signal is issued until it stops or reaches a constant rotation speed, and the input signal from the prime mover's rotation speed detector, the prime mover actually starts operating after the stop signal is output. A timer measures the time required to stop or reach a constant rotational speed, and compares the time determined by this timer with the standard stop time stored in the storage means, and based on the comparison result, detects abnormalities in the prime mover. 1. An abnormality detection device when a prime mover is stopped, characterized by comprising a determining means for determining whether the prime mover is present or not.
