<p>Circuit arrangement for monitoring scanning devices for displaying the operating states, which as specified are dependent on the direction of motion and occur independently thereof, of an object which can be reciprocated between two end positions, in particular a door leaf or the like, which scanning devices (1 to 3) are connected to a control device (4 to 9) for driving the object by motor, it being the case that for the purpose of guaranteeing the immediate monitoring tasks and of more effective handling of the function control for devices used to this end, the procedure is such that the scanning devices (1, 3) which operate as a function of the direction of motion, or at least one thereof, are connected both to a central evaluation circuit (4) and, parallel thereto, to one of the two switch units (5, 6), assigned to the motion of the object, of the control device (4 to 9), whereas the scanning devices responding independently of the direction of motion of the object, or at least one (2) thereof, are connected to the central evaluation circuit (4) and to both switch units (5, 6) oriented in terms of the direction of motion.</p> |
