Abstract

PURPOSE: To prevent erroneous action to be made at the moment when the service interruption (being caused by the abnormal stoppage of the outer equipment) is recovered, by providing abnormal signal memory circuit which maintains memories during service interruption at the abnormal signal input terminal part.
CONSTITUTION: Incineration control circuit 1 automatically controls the outer equipment 2 such as motor. Or circuit 3 makes logical addition of the outer abnormal signal EM1 and abnormal signal EM2 generated by control circuit 1. Output side of the OR circuit 3 is connected with (a) the output terminal ST which stops instantly the function of the control circuit thru the memory circuit 5, and (b) the alarm 4. When abnormality occurs, output of the OR circuit 3 is held at the memory circuit 5, outer equipment 2 is stopped and alarm is issued. Memory circuit 5 is employing the material wherein memorized content is not erased by the service interruption. Because the state of abnormality is memorized even after the service interruption is recovered, it enables the stoppage of resumed operation of the outer equipment 2 and the prevention of accident is secured accordingly.
