Single-Point Window Set
• Sets a single ON condition that extends 12.5% above and below the taught condi-
tion.
• All other conditions (lighter or darker) result in OFF output
• Sensing window size (sensitivity) is adjustable using the “+” and “-” buttons (Manual
Adjust)
• Recommended for applications where the target to be sensed may not always ap-
pear in the same place, or when other signals may appear.
Single-Point Set designates a sensing window, by setting two switching thresholds at
12.5% above and below the presented condition. The Output ON condition is inside the
window, and the Output OFF conditions are outside the window when Light Operate is
selected. Output ON and OFF conditions can be reversed by changing Light/Dark Op-
erate status in Setup mode.

Single-Point Window Set and Manual Adjust
Using Manual Adjust with Single-Point Window Set expands or contracts the size of the window. The lighted LEDs on the light bar sepa-
rate to a greater or lesser extent to exhibit the relative sensing window size.
