Abstract: A mobile control unit and a method remotely control an elevator installation in an inspection mode, wherein the elevator installation includes an elevator car, an elevator controller and a safety circuit. The elevator controller automatically controls the elevator car for movement in a normal mode of the elevator installation when the safety circuit is electrically closed. In order to control the elevator installation, the mobile control unit is connected to the elevator installation such that the mobile control unit can switch the elevator installation between the normal mode and the inspection mode, and the elevator car can be manually controlled for movement via the mobile control unit in the inspection mode of the elevator installation.

Abstract: A method for controlling an elevator installation uses a computer-controlled mobile device. The elevator installation includes an elevator shaft having a plurality of shaft thresholds each assigned to one floor, an elevator car having a car threshold and is moveable along the elevator shaft, and a control unit for moving the elevator car. The mobile device has an evaluation unit that communicates with the control unit. Information generated using at least one component of the mobile device as a result of a height deviation between the car threshold and a shaft threshold located opposite the car threshold is received in the evaluation unit, is then evaluated and control information for moving the elevator car is generated. The control information is sent to the control unit to move the elevator car such that the height deviation between the car threshold and the shaft threshold is minimized.
