Abstract:
PURPOSE:To easily detect the timing at which and the circuit block in which the cause of trouble occurs, by setting a special input at the time of recovering trouble of a device and successively executing the check of circuits while performing the same load control as normal operation and displaying the circuit block causing trouble at the time of the occurrence of abnormality. CONSTITUTION:It is checked whether the special input set state is set or not when the power switch of the device is turned on. The normal operation is executed if this state is not set. If this state is set, the check of each circuit block is started. First, the temperature signal inputted from a temperature sensor is checked. If this signal is in the high level through it is normally in the low level, abnormality is reported because of abnormal rise of the temperature or abnormality of the input part of the temperature sensor. Actual operation levels of the other sensors are compared with normal operation levels similarly after turning-on of the power switch, and abnormality is reported if abnormality is detected.
