TEACH Procedures
The instruction manual has detailed instructions for these TEACH modes:
• Window SET
• Light SET
• Dynamic TEACH
Window SET
• Sets window thresholds that extend a programmable % offset above and below the presented condition
• All other conditions (lighter or darker) cause the output to change state
• Recommended for applications where a product may not always appear in the same place, or when other signals
may appear
• See Program Mode in the user's manual for programming the Offset Percent setting (to increase/decrease the
window size)
A single sensing condition is presented, and the sensor positions window thresholds a programmable % offset above and
below the presented condition. In LO mode, Window SET designates a sensing window with the Output ON condition inside
the window, and the Output OFF conditions outside the window.

Light SET
• Sets a threshold a programmable % offset below the presented condition

• Recommended for applications where only one condition is known, for example a stable light background with
varying darker targets
• See Program Mode on page 5 for programming the Offset Percent setting
