Abstract:
PROBLEM TO BE SOLVED: To obtain an abnormality decision device capable of easily specifying an abnormal place and a controller capable of continuing the operation of an equipment without stopping control even when abnormality is generated in one position sensor in an automatic lock type door. SOLUTION: The abnormality decision dvice has a lock-position sensor 20 detecting the place of the lock of a lock means 10 and a release-position sensor 21 detecting the place of release, and the position sensor, in which the output signals of on → off or off → on are not changed, is decided as abnormality when a lock-means driving device 19 is worked. When the lock-means driving device 19 is operated, the abnormality of the lock-means driving device 19 is decided when the output signals of on → off or off → on are not changed in both position sensors 20, 21. When one position sensor in both position sensors 20, 21 is abnormal, the lock-means driving device 19 is controlled with time on the basis of the output signal of the other normal position sensor.
