Abstract: An elevator includes an elevator shaft defined by surrounding walls and top and bottom end terminals; an elevator car vertically movable in the elevator shaft; elevator hoisting ropes coupled to the elevator car; an elevator hoisting machine including a traction sheave engaged with the elevator hoisting ropes; a traction monitor configured to determine traction of the hoisting machine; an electromechanical brake; a measuring apparatus adapted to provide speed data and position data of the elevator car; and a safety processor associated with the traction monitor and the measuring apparatus. The safety processor includes an ETLS threshold configured to decrease towards the top and/or bottom end terminal in accordance with the position of the elevator car. The ETSL threshold is adjusted on the basis of the traction of the hoisting machine. The safety processor is configured to determine an elevator car slowdown failure if the speed data meets or exceeds the ETSL threshold.

Abstract: An elevator, an elevator control unit and a method for transferring data in an elevator arrangement, the elevator arrangement including at least an elevator shaft, an elevator car configured to move in the elevator shaft and at least one wireless communication channel, such as a wireless network, available for communication in the elevator shaft. The method includes determining signal quality and/or data transmission quality of the at least one wireless communication channel in different positions of the elevator car in the elevator shaft, moving the elevator car to a position or area selected based on the determined signal quality and/or the determined data transmission quality, and performing data transfer at the selected area or at the selected position of the elevator car.
