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, only for Bulkscan® LMS511, check the Optimization for belts with slits
or gaps checkbox (see "8.1.2 Optimization for conveyor belts with slits or gaps“ on
page 67).

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
66).

Ensure that hazard-free operation is possible
and start the empty conveyor belt.


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.
Average reference contour over Scan frequency Duration of the teach-in process
100 cycles 75 Hz 100 ÷ 75 Hz = 1,3 s
10,000 cycles 25 Hz 10000 ÷ 25 Hz = 400 s
Tab. 17: 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.
