Single-Point Static TEACH (Sensing Window)
• Sets a single ON condition
• All other conditions (lighter or darker) result in OFF output
• Sensing window size (sensitivity) is adjustable using “+” and “-” buttons
(Manual Adjust)
Single-Point TEACH is most useful when a product may not always appear in the same
place, or when other signals may appear. Single-point TEACH programs a sensing window,
with the Output ON condition inside the window, and the Output OFF conditions outside the
window (see Figure 4). Output ON and OFF conditions can be reversed by changing Light/
Dark Operate status in SETUP mode.
Single-Point TEACH programming may be accomplished only using Static TEACH. The
sensor learns a single sensing condition, and adds switching thresholds above and below
the taught condition to create a sensing window.
Single-Point TEACH and Manual Adjust
Using Manual Adjust with Single-Point TEACH expands or contracts the size of the window.
The lighted LEDs on the light bar separate to a greater or lesser extent to exhibit the relative
sensing window size.
