Abstract

PURPOSE:To secure an easy detection of the factor and the area for the fault with no error by making ineffective the function of other fault detecting means when a fault detecting means detects the fault. CONSTITUTION:Input signals FS1-FSn are checked through fault detectors D1 and so forth of fault detecting means DET1'-DETn', and the output signals are connected to fault indicator DSPF1 and so on which can perform resetting in terms of program via gate A1 and so forth along with output signal RSALL of OR circuit OR1 and also connected to OR1. As a result, if only one of DET1'-DETn' detects the fault and the fault is displayed on the fault indicator, the function of other fault detecting means is masked until the corresponding faulty indicator is reset even though the system may be confused therafter. Thus, the area of the first fault occurrence can be recognized easily.
