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 24
on page 33.

Figure 22. One-Point Window (Foreground Suppression)
In order to reliably detect changes from the taught background, if multiple laser reflections are returning to the sensor, the
output status is treated as though the target is outside of the taught window. The display alternates between
and
the measured distance. Realign the laser to avoid light reflecting off of multiple targets if this extra level of verification is not
desired.
Note: The sensor must be set to
=

amber to indicate One-Point Window (Foreground Suppression) mode.
