Abstract

PURPOSE: To provide a control system capable of reliably operating the controlled system even during the maintenance inspection period of such control system.
CONSTITUTION: A control system 2 for controlling a controlled system 1 consisting of A equipment 12 and B equipment 13 as controlled equipment comprises circuit units 3 and 4 each of which can be electrically and structurally cut off from the control system 2, each circuit unit containing a control circuit 5, an indicator circuit 6, and an indicator 7, and a control circuit 8, an indicator circuit 9, and indicator 10 respectively, a starting condition (a) is input to said control circuit 5 which givs an operation output (b) to A equipment 12, the indicator circuit 6 inputs a combined signal of an operating signal (c) of A equipment 12 and an operating signal (d) of B equipment 13 and gives an indicator signal to the indicator 7. The circuit unit 4 functions in an similar manner whereby an complex procedure to provide a cut off instruction in a operating manual can be eliminated and the controlled system can be reliably operated
