<p>PROBLEM TO BE SOLVED: To prevent an occurrence of a secondary disaster after an earthquake even when a battery of a standby power source is in a power loss state and an earthquake occurs during the power loss state, and improve reliability with a relatively simple configuration.SOLUTION: An elevator equipped with a device for performing a controlled operation in an earthquake for performing a controlled operation in an earthquake when an earthquake is detected by an earthquake sensor 4 includes the earthquake sensor 4 actuated by receiving power supply from power sources 1 and 2, and a power loss detection part 14 set to a no-power source state when there is no power supply from the power sources 1 and 2, and performs an earthquake controlled operation by a signal of a power loss signal output part 17. The elevator equipped with a device for performing a controlled operation in an earthquake further includes a power loss determination processing part 21 that performs initial processing once for setting the state of the power loss detection part 14 to a no-power source state in power return after a power failure.</p> |
