Abstract:
A monitoring device for checking for a predefined position of a body or for checking for the presence of a body, comprising a pivotal checking element (52), a motor (20) for driving the checking element (52) and a control device (50) for controlling the pivotal movement of the checking element (52), characterised in that the checking element is pivotable commencing from a starting position (150) through a transition region (142) into a monitoring region (144) in which the predefined position of the body lies or in which the presence of a body should be monitored, and in that the control device (50) limits the torque of the checking element (52) in such a manner that the maximum possible torque in the monitoring region (144) is reduced relative to that in the transition region (142).
