摘要： A method for taking an elevator of an elevator group into service mode includes entering in the input device of the elevator group a maintenance signal which comprises an elevator definition part, upon entering of the maintenance signal the elevator identified in the elevator definition part is removed from landing call allocation, the identified elevator is initiated to serve all remaining car calls and then to drive to a maintenance floor and to wait there for maintenance operation.

摘要： A safety control device applicable to an elevator system including an elevator car driven in an elevator shaft by means of a drive device, said safety control device comprising at least one sensor configured to detect, in the elevator shaft, a presence of an object in at least one specified area of the elevator shaft, and a controller configured to receive and process a signal of the at least one sensor indicating a detection result, and to conduct, when the detection result indicates the presence of an object in the at least one specified area of the elevator shaft, a safety procedure in which a switch from a normal drive control of the drive unit to a safety drive control is executed in which a target value set for the speed of the elevator car is decreased.

摘要： 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.

摘要： This invention relates to a method for defining absolute position information of an elevator car. The method comprises: obtaining continuously a pulse position information of the elevator car; and defining an absolute position information of the elevator car by adding a predefined correction value to the obtained pulse position information of the elevator car. The predefined correction value indicates a drift between the obtained pulse position information of the elevator car and the actual pulse position of the elevator car. The invention also relates to a safety control unit and an elevator system performing at least partly the method.

摘要： An elevator includes a car with at least two car doors, each car door being provided with a door contact, a shaft being provided with corresponding landing doors, each landing door being provided with a door contact, each landing door opening in synchronism with the corresponding car door, the door contacts forming part of a safety circuit of the elevator, a car door contact input being connected to a middle point in the safety circuit between a series connection of the car door contacts and a series connection of the landing door contacts. A status information of the car door contact input is monitored in order to determine whether the door contacts are operational or not when the car doors are opened and/or closed with a predetermined time delay at a landing.

摘要： A control arrangement of an elevator includes a safety gear, an over speed governor with a rope which is connected to the safety gear, a stopping device for generating an actuating force to the safety gear, and a drive unit for driving the elevator apparatus. In order to facilitate easy and efficient maintenance, the control arrangement includes a controller for controlling a triggered sequence to involve activating of the stopping device for braking with the safety gear, and controlling the drive unit to drive the elevator apparatus during braking with the safety gear until the safety gear stops the elevator apparatus.

摘要： Conventionally, elevator communications have been implemented using travelling cables. This is particularly the case when safety related data transmitted from an elevator car has to fulfil real-time restrictions often set by regulators so that the receiving of the information may not be delayed. Typically, this cannot be guaranteed when wireless transmission technologies are used. The reliability can be increased by using a second to supplement the wireless transmission.
