Abstract

PURPOSE:To make it possible to check the presence of disconnection at ease by providing a disconnection indicator which lights a main pilot lamp when none of individual pilot lamps is disconnected in a system which detects and indicates the abnormal conditions of plural check points. CONSTITUTION:If an individual pilot lamp Ln-1 is subjected to disconnection, the pilot lamp fails to light, even when a sensor Sn-1 detects an abnormal condition. As the potential at connection point Ln-1 is L, however, a main pilot lamp LO comes on if the output of AND gate G is L, and transistor Q1 is turned off while transistor Q2 is turned on. Therforem the operator can identify the disconnection of any individual lamps. When a check switch 2 is turned to 2a, the output of AND gate G is L and transistor Q3 is turned off while transistor Q4 is turned on. Each cathode of diodes D1 to Dn is grounded respectively and the main pilot lamp LO is put off. All individual pilot lamps come on except the pilot lamp Ln-1.
