Abstract: A backup circuit for supplying electricity to an electronic overspeed governor in connection with a malfunction of a main electricity supply is disclosed. The backup circuit includes an energy storage. The backup circuit is configured to disconnect the supply of electricity from the energy storage to the electronic overspeed governor with a delay when the malfunction of the main electricity supply is detected, and when the malfunction of the main electricity supply continues for a predetermined amount of time, restarting the supply of electricity from the energy storage to the electronic overspeed governor.

Abstract: A method and an apparatus for automatic condition checking of an elevator are provided, wherein an elevator car of the elevator is situated in a door zone of a first landing in an elevator shaft following an earthquake. The method includes determining whether the load carried by hoisting ropes is evenly distributed between the hoisting ropes by checking the status or measurement data of at least one rope tension measurement device. The test unit determines whether the elevator car is empty and conducts a drive test for the elevator car in order to determine unimpeded access for the elevator car to other landings. The elevator is returned to normal use, if the drive test indicates unimpeded access for the elevator car to the other landings.
