摘要: Safety device for motorized rolling shutter comprising a generator of signal representing the displacement and logic processing unit (10) capable working in learning mode operating recording samples comparing values obtained with order to control stopping motor (5) when there is an obstacle providing, if necessary, other functions such as automatic high position low position, or triggering alarm. The comprises pulley on which wound flexible element (9) whose end connected (8) shutter, that unrolling (1) drives axis mechanically generator, example synchronous motor.
