Abstract
A device for monitoring a machine movement of a movable constructional element includes a detecting device and a control device. The detection device comprises at least one transmission unit which transmits a signal, and a reception unit which receives the signal. The control device comprises an evaluation unit which evaluates the signal received at the reception unit. The control device allows the machine movement upon a receipt of the signal at the reception unit, and to output a first triggering pulse to stop the machine movement in an absence of the signal at the reception unit. The evaluation unit comprises a first threshold value measuring unit to detect a signal strength of the signal received at the reception unit and which, upon detection that a predetermined threshold value of a signal strength is fallen short of, outputs a second triggering pulse to stop the machine movement.
