<p>The method involves determining an offsetting parameter between a reference position of a screen and another reference position, for each screen from a group of motorized screens such as main screen (10) and offset slave screens (20-40), where one of the reference positions is a common reference position (R) to the screens. Each screen is coupled to a counting unit that defines a relative position of a load bar with respect to the former reference position of the screen or with respect to a latter reference position. An independent claim is also included for a method for group controlling of displacement of a group of screens.</p> |
