QS30 Series Diffuse-Mode Laser Sensor
Dynamic TEACH is best used when a machine or process may not be stopped for
teaching. 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 switch point 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 set point 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).
