PROBLEM TO BE SOLVED: To provide an elevator which makes an elevator device return to normal operation even in a state where a P-wave detection signal continues to be output due to failure of an earthquake sensor.SOLUTION: An elevator comprises an elevator device and an elevator controller to control the elevator device. The elevator controller comprises: an earthquake sensor; an earthquake control operation part which receives a P-wave detection signal from the earthquake sensor and makes the elevator device perform earthquake control operation; a failure detection part which determines failure of the earthquake sensor if no S-wave detection signal is output because the P-wave detection signal from the earthquake censor is continuously output for a predetermined period of time or longer; and a normal operation return part which makes the elevator device perform normal operation when the failure detection part determines failure of the earthquake sensor.SELECTED DRAWING: Figure 3

    【課題】地震感知器が故障によりP波検出信号が出力されたままの状態になったとしてもエレベーター装置を通常運転に復帰させるエレベーターの提供。【解決手段】レベーター装置と、エレベーター装置を制御するエレベーター制御装置を備えるエレベーターであって、エレベーター制御装置は、地震感知器と、地震感知器からのP波検出信号を受けてエレベーター装置に地震管制運転を行わせる地震管制運転部と、 地震感知器からのP波検出信号が一定時間以上継続出力されていてS波検出信号が出力されない場合、地震感知器の故障と判定する故障検出部と、故障検出部が地震感知器の故障と判定したときエレベーター装置に通常運転を行わせる通常運転復帰部と、を設けた。【選択図】図3
