<p>PURPOSE:To provide an abnormality detecting device which can detect whether a specific load is abnormal or not. CONSTITUTION:An abnormality detecting device contains a load driving means and a load control means 2 which instructs an operation to the load driving means. Then the detecting device is also provided with a voltage detector means 20 which detects the information applied to the load, a current detector means 30 which detects the information on the current flowing to the load, and a timer means 5 which counts a prescribed time after the means 2 instructs the load operation. Furthermore an abnormality deciding means 3 is added to decide the abnormality according to a fact whether both means 20 and 30 detect, the information on the voltage and the current corresponding to the load operation before the timer 5 counts a prescribed time, together with an abnormality display means 40 which shows the abnormality decided by the means 3.</p> |
