Abstract: The invention relates to a method for testing a capacity of a drive rescue battery for driving an electric motor of a transportation system in a rescue operation mode, wherein in normal operation mode AC means supply power over first, second and third phases via a low pass LCL-filter to a frequency converter for driving the electric motor, wherein the frequency converter comprises a rectifier circuit for providing a DC supply voltage. The method comprises the steps: disconnecting the LCL-filter from the AC mains; using inductors and capacitors of the LCL-filter, each of which being connected to the first or second phase, as a test load for testing the capacity of the drive rescue battery, wherein the inductor of the LCL-filter, which is connected to the first phase and downstream of the capacitor of the LCL-filter connected to the first phase, to the rectifier circuit, the capacitors of the LCL-filter connected to the first and second phases, and the inductor of the LCL-filter which is connected to the second phase and downstream of the capacitor of the LCL-filter connected to the second phase, to the rectifier circuit form a series connection as the test load; and determining at least one value of a voltage or a current of the drive rescue battery resulting from the test load. Other aspects of the invention are a software program realizing the method and a testing arrangement for testing the capacity of the drive rescue battery.

Abstract: The invention relates to an arrangement for releasing the operating brake of an elevator in an emergency situation and for driving an elevator car of the elevator to a floor level, comprising at least one electric operating brake of the elevator as well as a brake release lever, which brake release lever is connected with the brake via a mechanical transmission means, which arrangement further comprises an overspeed governor connected with a gripping device of the elevator car. According to the invention in between the brake release lever and the brake a coupling device is arranged, which coupling device is controlled by the overspeed governor. Via this means the car velocity is controlled also during release of trapped passengers.
