PURPOSE:To improve the availability of a controller to be controlled by detecting a specific component in a pulse signal and outputting a reset signal when the component is not within a specific range. CONSTITUTION:When a computer M22 goes beyond control and the execution of a program becomes abnormal, a cutoff means M24 is driven as long as the 1st specific component of the pulse signal from the computer M22 is not within the specific range, thereby stopping the controller to be controlled M21 from being controlled by the computer M22. An abnormality resetting part M26, on the other hand, outputs the reset signal to the computer M22 when the 2nd specific component in the pulse signal from the computer M22 is not within the specific range, so the computer M22 is initialized and starts processes from the beginning. |
