In general, temperature abnormalities, forced air cooling motor fan abnormalities, and power supply abnormalities that occur in the controlled device 2 require power shutdown with a relatively low failure rate. There are two types of power-off for the controlled device 2: normal power-off and power-off due to the occurrence of the various abnormal situations described above. In the case of abnormal power-off, the power must be turned on again after the abnormality has been removed, and this abnormality removal process Therefore, it is necessary to distinguish between normal and abnormal cutting.
Therefore, it is effective to have a control path that performs abnormal disconnection only when an abnormality occurs, rather than always causing abnormal disconnection. Further, according to the present invention, the abnormal cutting instruction 19
By setting a time difference from the disconnection failure interrupt notification 18, it is possible to distinguish it from other abnormalities.

As explained above, the present invention makes it possible to turn off the power more reliably by using an emergency cut-off instruction circuit that is different from that used for normal turn-on/cut-off instructions when a cut-off instruction fails, and also to issue a cut-off instruction when the power is turned on again. This has the effect of showing that the series is abnormal.
