Contrast Values
500+ Excellent: Very stable operation.
100-500 Good: Minor sensing variables will not affect sens-
ing reliability.
32-99 Low: Minor sensing variables may affect sensing
reliability.
0-31 Marginal: Consider an alternate sensing scheme.

• TEACH on-the-fly
• Sets a single threshold
• Threshold position is adjustable using the “+” and “-” buttons
(see Manual Adjust on page 11)
Dynamic TEACH is used to program sensitivity during actual ma-
chine run conditions. During Dynamic TEACH, the sensor takes
multiple samples of the light and dark conditions and automatically
sets the sensitivity at the optimum level. Dynamic TEACH activates
the sensor’s adaptive threshold system, which continuously tracks
minimum and maximum signal levels, and automatically maintains
centering of the switch point between the light and dark conditions.
The adaptive threshold system remains in effect during RUN mode
to automatically adjust for changes in the light or the dark condi-
tions.
When Dynamic TEACH mode is used to program sensitivity, the
output ON state (light or dark operate) will remain as it was last
programmed. To change to either light or dark operate, use the
SETUP mode (see
Sensor Setup on page 12).
Dynamic TEACH and Manual Adjust
Sensitivity may be adjusted at any time when the sensor is in RUN
mode by clicking the “+” and “-” buttons. However, when a manual
adjustment is made, the adaptive threshold system is disabled
(cancelled).
