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
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).
