Abstract

PURPOSE: To expect poor contact of a landing keylock switch, so as to prevent failures in advance, by providing voltage detecting units for detecting voltage on both ends of the landing keylock switch on respective stages, and detecting abnormalities of the landing keylock switches on respective stages on the basis of the detected both ends voltage. CONSTITUTION: Landing keylock switch both ends voltage detecting units 9 each of which is composed of a voltage input unit 10 for inputting both ends voltage of a landing keylock switch 1, an A/D converting unit 11 for converting the both ends voltage from an analog value to a digital value, and a transmission control unit 12 for transmitting the digital value to a control panel 2 are installed on respective stages. Output signals of respective voltage detecting units 9 are inputted into a landing keylock switch poor contact expecting calculating/controlling unit 13 in an operation control unit 3. At this time, the landing keylock switch both ends voltage for each stage are compared with the landing keylock switch poor contact expecting reference value when the landing keylock switches 1 on all stages are closed. When the landing keylock switch both ends voltage is not less than the expecting reference value, the landing keylock switch 1 on the stage is recognized as poor contact, and the stage is held as the poor contact expected stage.
