Abstract: A method for dynamically adjusting a levelling speed limit of an elevator car during a levelling operation includes obtaining an indication that the elevator car is detected to arrive to a zone; obtaining at least one value indicating the speed of the elevator car, in response to detecting that the elevator car arrives to the zone; and dynamically adjusting the levelling speed limit of the elevator car based on the speed of the elevator car. An elevator control unit and a system are provided to perform at least partly the method.

Abstract: A safety circuit board for controlling an electromechanical brake and motor controller of a passenger transport installation includes at least one processing unit, a main safety output with an associated relay connected to the at least one processing unit and providing a connection to the electromechanical brake and motor, and a secondary safety output with an associated relay connected to the at least one processing unit and providing a connection to the electromechanical brake and motor. The main safety output and the secondary safety output are configured in parallel enabling control of the electromechanical brake and motor with the at least one processing unit using either of the safety outputs.

Abstract: This invention relates to a method for performing a synchronization run for an elevator stopped between floors. The method comprises: upon initiating the synchronization run, driving an elevator at a low speed in order to detect a first magnet of the elevator shaft detecting a first magnet of the elevator shaft, comparing the identification code of the detected first magnet to the stored pre-information in order to identify the detected first magnet, in response to identification of the first magnet, generating a control signal to the elevator car to travel up to an elevator rated speed, and driving an elevator car with an elevator rated speed.

Abstract: According to an aspect, there is provided a communication system for transmitting safety information in an elevator system. The communication system comprises a first node; and a second node ; wherein the first node is configured to receive first safety information from a first safety node via two parallel communication channels, to convert the received first safety information into a serial form for transmission in a first safety message over a single communication channel between the first node and the second node and to transmit the first safety message to the second node over the single communication channel; and the second node is configured to receive the first safety message and to convert the first safety information in the first safety message back into the parallel form for transmission via two parallel communication channels to a second safety node.

Abstract: In order to improve safety, an escalator system is configured to drive an escalator in response to a signal received from a user interface located in a first end of the escalator, and to stop movement of the escalator in response to detection of opening of an access cover plate in a second end of the escalator.
