摘要

The signal output circuit of the highest rank state detection section outputs an abnormal signal that is generated by the processing device when an abnormality is detected by the abnormality detection section. When no abnormality is detected, a normal signal is generated by the processing device and output as the detection signal. In each state detection section other than that of the highest rank, the signal output circuit outputs an abnormal signal generated by the processing device when an abnormality is detected by the abnormality detection section, and outputs the detection signal input from a higher rank state detection section when no abnormality is detected.
