Abstract: In a method for performing a manual drive in an elevator after mains power-off, the frequency converter of the motor is separated from mains, any safety blocking of the brake drive and/or motor drive is disabled, current is supplied from the battery to the brake drive to open the elevator brake and current is supplied from the battery to the drive control to allow regulation of the motor speed via the inverter bridge, the manual drive control observes the motor speed via the speed sensor and starts a speed feedback loop to regulate the motor speed to a manual drive reference value by feeding a three phase-AC current to the motor windings via the semiconductors of the inverter bridge, which manual drive speed reference is lower than the speed reference for normal elevator operation, when the car reaches a floor level the floor level indicator is activated, and the actuator is released whereafter the current supply from the battery to the elevator brake is interrupted and the previous disabled safety blocking of the brake drive and/or motor drive is enabled again.

Abstract: The method of performing maintenance of an elevator is performed by unlocking and opening a landing door at a lowermost landing manually, activating a first stop button in the shaft, whereby a safety circuit of the elevator is opened so that operation of the car is completely prevented, entering into the shaft, closing the landing door, climbing down from the lowermost landing to the pit, turning a drive switch in a maintenance control unit positioned in the pit into a maintenance drive mode, whereby the first stop button is by-passed so that the car can be driven from the maintenance control unit upwards and downwards in the shaft.

Abstract: Elevator safety and safety related information needs to be sent reliably to safety controlling systems. Existing elevator communication devices may be used for transmitting this information by processing the received safety and safety related information and processing it before sending it over the communication bus from the elevator car or floor equipment to the controlling devices. A separate communication unit may be used for receiving and processing safety and safety related data packets before they are transmitted over a common bus used for safety and safety non-critical submission.

Abstract: Elevator components can be equipped with an electronic information plate. The electronic information plates are associated with a particular electronic information plate that can store different properties of the associated component. The content of each electronic information plate is read manually or automatically and transmitted to a controller. The controller analyzes the received content and launches a predetermined action if the content indicates a need for maintenance.

Abstract: In an elevator, the status information of the receivers, and possibly also of the transmitters, of a light curtain of the elevator is transmitted from the control unit of the light curtain as a response to a query or as messages. The control system of the elevator car is configured to receive the responses or status information and to analyze i) the status information contained therein of at least one receiver the status information contained therein of at least one receiver and of at least one transmitter relating to it, for changing or adjusting the operating mode of the elevator or for giving a control command to the operating system of the elevator.

Abstract: A method and a safety arrangement are provided for monitoring the movement of an elevator component, more particularly of an elevator car or of the automatic door of an elevator. In the method, a setup drive of an elevator component is run, and the speed and/or acceleration of the elevator component is measured during the setup drive, a threshold value for the speed and/or acceleration of the elevator component is formed on the basis of the measuring data obtained in the setup drive, the speed and/or acceleration of the elevator component is measured, and if the measured speed and/or acceleration exceeds the aforementioned threshold value, a monitoring signal for bringing the elevator to a safe state is formed.
