For reproducible measurements, the measuring system typically needs a warm-up
time of 20 min.

4.8 Material Height Detection
To avoid collision of high materials with the sensors, a light barrier – consisting of a trans-
mitter and a receiver – records the height of the material before it enters the measuring
system. If, for example, a bulge in the material is detected, both measurement carriages
move to the parking position.
i
The measurement carriages require about 6 seconds to reach the parking position.
When determining the installation location for the laser light barrier, consider the
speed at which the material travels.
Attach the transmitter and receiver of the laser light barrier at the material feed.
Adjust the receiver’s sensitivity to the material being measured.

CAUTION
Danger of crushing
between the measuring
system and fixed compo-
nents. Do not reach be-
tween base frame, linear
guide, attachments and
belt material while meas-
urements are performed.
Do not stay within the
range of moving com-
ponents while measure-
ments are performed.
