Table 4: Expected TEACH Behavior for One-Point Window (Foreground Suppression)
See
Figure 24
on page 33 for the minimum object separation.
Condition
TEACH Result
Display
One valid TEACH point with both switch
points in range (with offset, if applicable)
Sets a window (two switch points) centered around the
taught distance. The ± window size is the vertical minimum
object separation. The two switch points always stay
within the specified sensing range.
The ± window size flashes on the display.
One invalid TEACH Point
Sets a window (two switch points) centered around 150
cm. The window size is ± 7.5 cm.
and the window center point
distance flash alternately on the display.
One valid TEACH point with one switch
point within range and one switch point out
of range (with offset, if applicable)
Sets a window (two switch points) that is centered at the
TEACH point (after offset, if applicable) with one switch
point at the maximum range.
and the ± window size flash
alternately on the display.
One valid TEACH point that, after the offset,
results in a both switch points outside of the
range
Sets a window (two switch points) centered around 150
cm. The window size is ± 7.5 cm.
and the window center point
distance flash alternately on the display.
3.6.4 One-Point Background Suppression
One-point background suppression sets a single switch point in front of the taught target distance. Objects beyond the
taught switch point are ignored. The switch point is set in front of the taught target distance by the vertical minimum object
separation. See
Figure 24
on page 33.
