Abstract: An elevator communication system includes a first elevator controller; a second elevator controller; and a first ethernet bus portion connected to the first elevator controller, the first ethernet bus portion having sequential bus segments interconnected by at least one switch. The first ethernet bus portion is arranged in a first elevator shaft. A second ethernet bus portion is connected to the second elevator controller and includes sequential bus segments interconnected by at least one switch. The second ethernet bus portion is arranged in a second elevator shaft. A switch of the first ethernet bus portion and a switch of the second ethernet bus portion are interconnected to enable data transmission between the switch of the first ethernet bus portion and the switch of the second ethernet bus portion. The first elevator controller is communicatively connected to the second elevator controller.

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: The arrangement comprises a drive driving an electric motor, a contactor and a control circuit connecting a control coil of the contactor to a power supply. The control circuit comprises a manual control part provided with a manually operated first switch, and an electronical control part provided with an electronically operated second switch and a processor controlling the second switch. The first switch and the second switch are connected in series in the control circuit with the power supply and the control coil of the contactor so that de-energization of the control coil of the contactor may be done either by the first switch or by the second switch.

Abstract: An elevator safety system includes a safety controller in connection with an elevator safety chain for monitoring safety of an elevator system. The elevator safety system is arranged, in a first configuration of the elevator safety system, to monitor a set of safety devices, and arranged to be reconfigured from the first configuration to a second configuration of the elevator safety system in response to a detection of a malfunction or failure in a portion of the first configuration, wherein, in the second configuration, the malfunctioned or failed portion is at least functionally excluded. An elevator system and a method for continuing operation of an elevator system after a malfunction or failure are also disclosed.

Abstract: A method for preventive maintenance of an elevator speed sensor system includes at least a first and a second sensor, which are independent of each other. The method includes: determining a reference distance for an elevator car travel between a first door zone and a second door zone, during the elevator car travel, defining continuously a first elevator car speed information from the first sensor and a second elevator car speed information from the second sensor, calculating a cumulative sensor system error by integrating the difference between the first elevator car speed information and the second elevator car speed information, and dividing the cumulative sensor system error with the reference distance to obtain a sensor system performance indicator.
