Description of operation
The MLG-2 offers the following beam functions: “Parallel beam”, “Cross beam switch‐
ing” and “Cross beam measuring.” The system automatically selects the “Parallel
beam” or “Cross beam switching” function depending on the specific object size that is
to be detected. As an alternative, the user also has the option of manually activating
the “Cross beam switching” or “Cross beam measuring” function.
In the “Cross beam switching” option, the crossed beams are also used for object
detection. The crossed beams do not affect the beam status, beam functions or
blanked beams.
In the “Cross beam measuring” function, a group of crossed beams is combined into a
single virtual beam. Virtual beams are treated as additional real beams and do not
have any affect on the beam status, beam functions or blanked beams. If the “Cross
beam measuring” function is activated, the real and virtual beams are renumbered,
which means that the number of beams is nearly doubled.
