separation
One valid distance with one invalid
TEACH point
Two invalid TEACH points

3.6.2 Dynamic Background Suppression TEACH

Dynamic TEACH sets a single switch point during machine run conditions. Dynamic TEACH is recommended for applications
where a machine or process may not be stopped for teaching. The sensor takes multiple samples and the switch point is
set between the minimum and the maximum sampled distances.
