Abstract

PURPOSE: To improve safety by installing detecting switch to detect the action of electromagnetic valve, abnormality decision circuit to output an abnormality signal depending on detection results, and identification means to carry out an abnormality identifying action.
CONSTITUTION: More time than predetermined elapses before a detection signal could be output by the first action detector switch following the excitation of exciting coil 5A, when an abnormality has occurred on the first electromagnetic valve 1. As the said time exceeds the time set by the first valve action-time detector timer, the first valve abnormality signal is output by the first valve abnormality decision circuit 15. This valve abnormality signal is differentiated by differentiation circuit 19 and then input into the memory circuit 21. After this process, its memorized condition is inverted, causing the first display-side control switch 24 to be turned off and a lamp for the first abnormality display means 26 to be off. In this way, an abnormality on the first electromagnetic valve 1 side is warned.
