Table 3: Expected TEACH Behavior for Dynamic Background Suppression
See Figure 16 on page 23 for the minimum object separation.
Condition
Two valid distances that are greater
than or equal to the horizontal
minimum object separation
Two valid distances that are less than
the horizontal minimum object
separation
One valid distance with one invalid
TEACH point
Two invalid TEACH points

3.6.3 One-Point Window (Foreground Suppression)

One-point window sets a window (two switch points) centered around the taught target distance. Loss of signal is treated
as a detection in One-Point Window mode. The size of the taught window is the vertical minimum object separation. See
Figure 16 on page 23.
Manually adjust the window size from Run mode using
