Dynamic TEACH is a variation of two-point TEACH. It programs the sensor during actual
machine run conditions, taking multiple samples of the light and dark conditions and
automatically setting the threshold at the optimum level (see Figure 3).
Dynamic TEACH activates the sensor’s adaptive threshold system, which continuously
tracks minimum and maximum signal levels, and automatically maintains centering of the
threshold between the light and dark conditions. The adaptive threshold system remains
in effect during RUN mode. The adaptive routine saves to non-volatile memory at least
once per hour.
When Dynamic TEACH mode is used, the output ON state (Light or Dark Operate) will
remain as it was last programmed. To change the output ON state, use SETUP mode
(see page 8).
The sensing threshold may be adjusted (fine-tuned) whenever 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).
