Abstract

PURPOSE:To make the promotion of prevention from an error indication of the indicator lamp, by making a state indication operated of the indicator lamp after the state of controlled equipment is completely inverted by the operation command. CONSTITUTION:By a closing operation command a controlled equipment 52 is closed by an on-control switch 5a. with the switch 5a turned off, a transistor Q3 is made off with a current flowing in an on-state detecting switch 52a of the equipment 52, and a transistor Q2 energizes a relay RY2 to turn off a relay RY1 with an indicator lamp made switching. Subsequently, an off-control switch 6a turns off a transistor Q4 to open the equipment 52. With the switch 6a turned off, a transistor Q1 is made on by a current flowing in an off-state detecting switch 52b of the equipment 52, with the relay RY1 made on and the relay RY2 made off, and the indicator lamp is switched. With a fault contact 30 made open, no current flows in the link line, and the both of the relays RY1, RY2 are turned on to light a lamp 0, with an error indication never caused.
