Abstract

PURPOSE:To detect a runaway caused by a noise, by providing a pulse detecting circuit for detecting whether a continuous pulse exists or not, and an oscillating circuit for oscillating in a state that the continuous pulse is stopped by an output of said pulse detecting circuit, and repeatedly resetting a computer by the oscillating circuit. CONSTITUTION:In an input interface 70, a program runaway preventive device 72 is placed. Outputs of sensors 74a, 74b and 74c are converted to input signals to a microcomputer 10 by an input interface 70. The microcomputer 10 compares each output of each sensor 74a-74c in order with a value stored in advance, at prescribed time intervals, and discriminates whether a fault or necessity of an alarm exists or not. In case it has been discriminated that an alarm is necessary, corresponding alarm indicators 78a-78c are operated through an output interface 76.
