Dynamic TEACH is used to program sensitivity during actual

machine 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 conditions.

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

10).

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).
