SICK MLG-2 ProNet - Cross Beamfunction

The following options are available for configuring the minimum attenuation:
•
Approx. 10% signal attenuation: clean PET bottles, clear glass, thin and clear films
(e.g. cellophane), household plastic film, plastic wrapping
•
Approx. 15% signal attenuation: clean clear glass bottles, thicker films, wrapping
folded multiple times
•
Approx. 30% signal attenuation: green and amber glass, colored glass bottles
NOTE
The minimum attenuation that an object must have in order to be detected increases
with the sensing range (see "Minimum attenuation in Transparent Mode", page 163).

Description of operation
The MLG-2 offers the beam functions parallel beam, cross beam switching and cross
beam measuring. Depending on the object size to be detected, the system automat‐
ically selects the parallel beam or cross beam switchingfunction. Alternatively, the
user has the option of manually activating the cross beam switching or cross beam
measuring function.
With the cross beam switching function, the crossed beams are also used to detect
objects. The crossed beams do not affect the beam status, beam functions or blanked
beams.
With 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. When the cross
beam measuring function is activated, the real and virtual beams are renumbered,
almost doubling the number of beams.
