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
