The method involves transporting an object on a carrier device (12) through a passage. The passage is protected by a light grid (16) with multiple light rays (22), which run above each other. The light grid is separated in a lower area (16a) and another upper area (16b). The lower area passes through the carrier device and the upper area passes through the object, where the light grid comprises an evaluation circuit. An independent claim is also included for a light grid with an evaluation unit for execution of a passage monitoring method. |
