Abstract: A sliding door (B) that is operated with a door drive is moved with the aid of a lever arm (A) that is driven by a motor (M) via a gear. The end positions of the door, as well as two intermediate positions, are detected with mechanical switches (C) that are actuated by a cam disk (K). The mechanical switches (C) form a redundant safety system and, if necessary, can be omitted. A non-contacting sensor (S) is used independent of the mechanical switches (C). For the purpose of detecting the position, the sensor can fully replace the mechanical switches (C) and the cam disk (K) for actuating these switches. With the aid of a transmitting wheel (D) and the sensor (S), it is possible to draw a conclusion relating to the rotational speed as well as the door position. A central data processing unit (CPU) permits the control and adjustment of the door drive. A diagnostic evaluation of the door drive with respect to required maintenance operations is furthermore possible with the central data processing unit (CPU).

Abstract: A gate operator with an extensible actuating arm adapted for light to moderate gate passing traffic. The operator comprises a small drive unit, such as an electric motor drive, and a rotatable drive shaft, such as a worm shaft driven through operation of the motor. An extensible shaft or so-called ball race shaft, cooperates with the rotatable shaft and extends inwardly or outwardly in response to rotation of the rotatable shaft. A microprocessor operated control circuit is used with or forms part of the operator, and measures a number of counts generated by magnetic elements rotatable with the worm shaft, and which are equivalent to distance units of measurement. In this way, the distance on the opening and closing movement is measured and stored in the microprocessor, so that on subsequent movements, the gate can open and close to precisely the open and closed positions without stopping short of or banging into such end positions.
