6.2 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 6 on page 15).
