Summary:An automatic firing arrangement (1) has an apparatus for actuating a fan which is driven by a controllable-speed asynchronous motor (2). The apparatus includes a frequency converter (3) with which the speed of rotation of the asynchronous motor (2) is controllable, switching devices (6.1; 6.2; 6.3) by which the asynchronous motor (2) can be temporarily separated from the power supply for a predetermined period of time, and a measuring means (5) with which the speed of rotation and the direction of rotation of the asynchronous motor (2) can be detected by way of the generator action thereof in said period of time.
