Abstract: A method for operating an elevator having a car, a drive engine, shaft doors, signal receptors, an engine controller and a door controller. Each of the shaft doors is reciprocally opened and closed by an associated active door drive and has one of the signal receptors thereat. The method includes: receiving a requesting signal at one of the signal receptors; responding to the requesting signal by instructing the engine controller to control the drive engine to displace the car to a first position with the car roof adjacent to the shaft door at the floor from which the requesting signal originated when that floor is not the lowermost floor, and when the floor is the lowermost floor to a second position above the lowermost floor; instructing the door controller to control the door drive to actively open the door; and switching the engine controller to an inspection mode.

Abstract: A method and position determining arrangement determine a current precise position of an elevator car driven by a drive engine along a hoistway. An encoder cooperating with the drive engine provides a first signal indicating with a high precision the position of the car within a partial hoistway range extending along a fraction of the entire car travel path. A rough position indicator provides a second signal indicating with a low precision the position of the car within the hoistway. A current rough position of the car is determined based on the second signal and deviating from an exact real position of the car up to an first inaccuracy length; and the current precise position of the car is based on the first signal taking into account the current rough position and deviating from the exact real position up to a second inaccuracy length smaller than the first inaccuracy length.
