In the “With search fields” device mode, the user specifies the MLG-2 expected areas
(search field) for the edges to be tracked. For the specific edge he/she numbers, the
user defines a spatial area within the measuring range (search field for edge Ex) in
which this edge Ex is expected.
An edge detected in this area by the MLG-2 is assigned as edge Ex. If desired, the user
can label the outer edge as desired. If two edges are detected in this range, the sensor
does not detect this as en edge.

Figure 55: Search fields around edges
If the number of edge changes, e.g. with a band crack, assignment of other edges
remains and these can continue to be tracked.
Figure 56: Received assignment of edges in the event of band cracks
If the search fields are measured very tight and edges are to run out of the search fields
assigned to them (in the example, E1 and E2), they are no longer interpreted by the
MLG-2 and also no longer output. Functions assigned to these edges such as the width
of the object with edges E1 and E2 are no longer defined and can also not be output
even though the object is also located in the measuring range of the MLG-2.
