Adjust Mode
Sliding the RUN/PRG/ADJ mode switch to the ADJ position allows the user to perform Expert TEACH/SET methods and
Manual Adjustment of the threshold(s).
TEACH Procedures
The instruction manual has detailed instructions for these TEACH modes:
•
Two-Point TEACH
• Dynamic TEACH
• Window SET
• Light SET
• Dark SET
• Calibration SET
Two-Point TEACH
• Establishes a single switching threshold
• Threshold can be adjusted by using the "+" and "-" rocker button (Manual Adjust)
Two-Point TEACH is used when two conditions can be presented statically to the sensor. The sensor locates a single
sensing threshold (the switch point) midway between the two taught conditions, with the Output ON condition on one side,
and the Output OFF condition on the other.

The Output ON and OFF conditions can be reversed by using the LO/DO (Light Operate/ Dark Operate) switch.
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.
