    Abstract: Elevator components can be equipped with an electronic information plate. The electronic information plate 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 possible mistake or a fraud.

    Abstract: The invention relates to a method for verifying speed data of an elevator car for overspeed monitoring of the elevator car. The method comprising obtaining at least one continuous speed data of the elevator car at two channels; obtaining a zone speed data of the elevator car within at least one zone of an elevator shaft at two channels, generating a two-channel verified speed information by comparing the said at least one continuous speed data to the zone speed data at least at one channel; generating a control signal, if the comparison indicates a mismatch at least at one channel; and if the comparison indicates a match at each of the at least one channel in which the comparison is provided; the method further comprising comparing the verified speed information at each channel between each other; and generating the control signal, if the reciprocal comparison indicates a mismatch. The invention also relates to a safety control unit and an elevator system performing at least partly the method.

    Abstract: A sensor connecting unit includes a safety input for connecting with a sensor; a power supply that is controllable through a controllable power switch; and a first I/O processing unit and a second I/O processing unit being connected to each other through a reciprocal comparison communication channel. The first I/O processing unit and the second I/O processing unit are both connected through a measurement circuit to measure voltage, current or power between a reference input and the safety input, and connected to a safety bus. The first I/O processing unit informs the second I/O processing unit about switching off of the controllable power supply, the second I/O processing unit commands the first I/O processing unit to switch off the controllable power supply, and/or the second I/O processing unit measures an output of the controllable power switch to detect switching of the power switch.

    Abstract: It is desired that elevators are not operated when the brake is not completely released. Thus, the disengaging of brakes must be monitored or guaranteed otherwise. For providing guaranteed opening, the current for opening the brake is determined and then an additional current is provided to the brakes in order to guarantee the opening. The current for opening the brake is determined by doing a test sequence for each brake individually. In the test sequence, one brake is used to hold the elevator. Then, a momentum is applied to the elevator for moving the elevator car. The current is determined by increasing the current to the engaged brake gradually until the elevator moves. When the movement is detected, the current value is stored. When the elevator is operated regularly, the additional current is added to the stored value.

    Abstract translation: 当制动器未完全释放时，希望电梯不被操作。 因此，必须对制动器的分离进行监测或保证。 为了提供保证的开度，确定用于打开制动器的电流，然后向制动器提供额外的电流以保证开启。 单独制动每个制动器的测试顺序来确定打开制动器的电流。 在测试顺序中，使用一个制动器来固定电梯。 然后，向电梯施加动量以移动电梯轿厢。 电流通过逐渐增加到接合的制动器的电流直到电梯移动来确定。 当检测到移动时，存储当前值。 当电梯定期运行时，附加电流被加到存储的值。

    Abstract: The invention refers to an elevator rescue system (10) for moving an elevator car of an elevator in an emergency situation, which elevator includes an elevator motor acting on hoisting ropes by which the elevator car is suspended and/or moved, which elevator motor comprises at least one electro-mechanical brake (14a, 14b) and an encoder outputting a signal corresponding to its speed,which system comprises a back-up power source (36), a jerk monitoring circuit (22) connected to the encoder and comprising a memory (28) for at least one first upper threshold value for the car acceleration and/or its derivation, a brake feed circuit (16) which is controlled by the jerk monitoring circuit, at least one release switch (24) which is connected to the jerk monitoring circuit and/or to the brake feed circuit, in which system the operation of the release switch activates the brake feed circuit to release the brake, and initiates the jerk monitoring circuit to compare the car acceleration and/or its derivation as derived from the encoder signal with the stored first upper threshold value, whereby it forwards a control signal to the brake feed circuit to initiate/stop braking depending on the comparison result.
