4.10 Monitoring the conveyor belt edge
The Bulkscan monitors the position of the conveyor belt by detecting its left and right
edges.Thedistancebetweentheconveyoredgeandtheendofthemeasurementeld
is calculated.

Fig. 7: Belt monitoring
Theconveyorbeltedgesaredetectedusingtwoadditionalmonitoringelds(leftand
rightfromthemeasurementeld).Theseedgesaredetected,whentheconveyorbelt
lieswithinthecongurabledetectionlimits.
Distance from conveyor belt edge smaller
than maximal allowed distance. No warning
is issued.
Distance from conveyor belt edge greater
than maximal allowed distance. A warning
is issued.

Abb. 8 Signaling of belt edge warnings
The Bulkscan can monitor the distance from the conveyor belt edge and signal on a
digitaloutputifthevalueexceedsacongurableminimaldistance.
• Pay attention to the correct angular adjustment of the sensor to obtain meaningful
values for the distance to the belt edge (see "8.1 Teaching-in the reference contour“
on page 53).
• Youcansmooththemeasuredvalueswiththeaidoftheaveraginglter(see"4.11
Averaginglter“onpage24).
