Dynamic TEACH
• Teaches on-the-fly
• Establishes a single switching threshold
• Threshold can be adjusted using “+” and “-” rocker button (Manual Adjust)
Dynamic TEACH is best used when a machine or process may not be stopped for teaching. The sensor learns during actual sensing
conditions, taking multiple samples of the light and dark conditions and automatically setting the threshold at the optimum level (see
Figure below).

The output ON and OFF conditions can be reversed using the LO/DO switch (see LO/DO Switch in Top Panel Interface on page 2).
Dynamic TEACH and Manual Adjust
• Moves switching threshold value up or down to make adjustments
• Slide Mode switch to ADJ to enter Adjust mode
• Press “+” to increase; press “-” to decrease
• GREEN display shows the switching threshold value
• 2 seconds after adjustment, GREEN display will flash 3 times to confirm
• Slide Mode switch to RUN to complete operation
Remember: Manual adjustments are disabled when Auto Thresholds are ON
