Patent ID: 7515338

Claim:
A method for operating a motorized screen device ( 1 ) comprising: winding a screen ( 2 ) windable on a winding tube ( 3 ) whose angular position is measured by a sensor ( 12 ); latching a free end ( 4 ) of the screen in a defined position in which the screen is at least partially unwound from the winding tube ( 3 ), the position termed latched (P 2 ) in the direction of winding, the latching being activated in this direction if the free end ( 4 ) of the screen previously reaches at least one position of reversal (P 3 ), to which corresponds for the unwinding a value of angular position of the winding tube termed the position of reversal of rotation (D 3 ), situated beyond the latched position (P 2 ) in the direction of unwinding of the screen, wherein, in a mode of configuration of the latching of the screen ( 2 ), the installer proceeds merely to record the value of a chosen angular position, termed the recorded rotation reversal position (DM), this position being situated at the level of or beyond the position of reversal of rotation (D 3 ), in the direction of unwinding of the screen ( 2 ).
