A system for detecting an out-of-operation state of an elevator system includes a monitoring unit and a sensor unit. The sensor unit is configured to: detect at least one event indicating a generation of an elevator call and provide a message indicating the generation of an elevator call to the monitoring unit. The monitoring unit is configured to: initiate a time measuring function in response to receiving the message from the sensor unit, monitor a response of the elevator system to the generated elevator call. A method for detecting an out-of-operation state of an elevator system is also disclosed.

A system for the generation of call advance data for an elevator control, which system is going to be installed in an elevator car moving in an elevator shaft and includes at least one acceleration sensor outputting current acceleration data and/or magnetometer outputting a magnetic flux signal which includes current magnetic flux data at the current position of the elevator car, which acceleration sensor and/or magnetometer is mounted in connection with the elevator car; a velocity calculating unit which calculates from the current acceleration/magnetic flux data current car velocity data; a position calculating unit which calculates from the current acceleration/magnetic flux data and/or from the current car velocity data current car position data; and a call advance processing unit which calculates from the current car velocity data and the current car position data call advance data which designates the time until which the car is able to stop at the next approaching floor in travelling direction, which call advance data is transmitted to a call allocation unit of an elevator control. Call advance data is provided in an easy manner without using existing car position detection devices of an existing elevator to be modernized.

Methods for the modernization of an elevator group which includes a plurality of elevators each with a car and an elevator controller for controlling the respective car. At least one input terminal is mounted for acquiring destination call signals and a group computer is installed in the course of the modernization process. The group computer is suitable for evaluation of the destination call signals as well as for the output of at least one first control signal. For each elevator furthermore a respective control unit is installed for reading in the first control signal and a control module is installed at the respective car for issuing an internal call for the respective car initiated by the first control signal.

In the modernization of a hall display device, the number of cables connected to operating equipment may increase since the shape and the number of pushbuttons, indicators and the like are changed. In this case, it is necessary to further process a hole at the worksite for passing the cables in accordance with the number of cables, which makes the work complicated. In the present invention, a frame having an opening in the center is fixed to a hall wall, and a front plate having operating equipment is fixed in a way as to cover the opening on the hall side of the frame. A back plate having a hole for passing cables is detachably fixed in a way as to cover the opening on the elevator hoistway side.

The present application relates to an elevator system and a method of adapting an elevator system, the system being adapted to warn elevator users of the existence of a vertical misalignment between a floor of a lift car and a landing surface adjacent to which the lift car stops. The elevator system comprises facing parallel walls that depend vertically downwards from a leading edge of the lift car floor and a leading edge of the landing surface respectively. A luminaire is mounted on at least one of said walls at a distance below the edge of said wall so as to face the opposing wall irrespective of said vertical misalignment. Light from said luminaire illuminates said opposing walls to alert elevator users to the existence of said vertical misalignment.

Disclosed is a method for retrofitting an elevator machine with a thrust bearing, including removing, from a bearing stand, a first cover plate, providing access to an end portion of a motor shaft, securing an extension shaft against the end portion of the motor shaft, securing a thrust bearing housing against or axially offset from the bearing stand, positioning a thrust bearing in the bearing housing, wherein an inner race of the thrust bearing is securely positioned against, and axially fixed to, the extension shaft, and an outer race of the thrust bearing is securely positioned against the bearing housing, and securing a second cover plate to the bearing housing.

A multi-use interface for use in an elevator includes an input device to receive input and a selection device associated with the input device, the selection device to select between an operation mode and a service mode, wherein the operation mode allows the input device to receive a standard elevator function input, the multi-use interface generating a standard elevator function output in response to the standard elevator function input, and the service mode allows the input device to receive a service function input, the multi-use interface generating a service function output in response to the service function input.
