Figure 19. 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
=
to use the following instructions. The FGS indicator is amber to
indicate One-Point Window (Foreground Suppression) mode.
Note:
To program the sensor using remote input, remote input must be enabled (
