COMMISSIONING
Set the
Maximum distance
(scan radius):
◦
Enter the distance using the keyboard.
or:
◦
Click and drag the gray distance line to the required radius.
Enter the number of scan cycles over which the sensor is to determine the reference
contour in the
Average reference contour over
field. A large value with a heavily vi
-
brating conveyor belt will result in a better averaged reference contour. The teach-in¬
process takes correspondingly longer.
If necessary, check the Optimization for belts with slits or gaps checkbox (see "8.1.2
Optimization for conveyor belts with slits or gaps“ on page 56).
If required, move the
Level compensation
slider to compensate for raising or lower-
ing of the conveyor belt (see "8.1.1 Compensation of the conveyor belt level“ on page
Ensure that hazard-free operation is possible
and start the empty conveyor belt.

Tab. 12: Indicators during teach-in
If the teach-in process was not successful: Check the ambient conditions and/or
adjust the configuration and repeat the teach-in process.
If the teach-in process was successful: Start the measuring mode.
• The duration of the teach-in process is dependent on the settings selected:
• During the teach-in the sensor will not respond to terminal commands. Terminal
commands sent to the sensor during this time will not be cached.
•
If you change the aperture angle during the configuration, then the reference contour
should be taught-in again for optimization.

10.000 ÷ 35 Hz = 286 s
Tab. 13: Examples of the duration of the teach-in process
8.1.1
Compensation of the conveyor belt level
Due to the weight of the bulk the conveyor belt may drop or may lift:
•
Conveyor belt dropping
: Due to the weight of the bulk, the conveyor belt may drop
between transport rollers.
•
Conveyor belt lifting
: Due to the weight of the bulk, the tension on the conveyor belt
on the neighboring transport roller sections may be increased and as a result the
conveyor belt may lift.
