Pushbutton
A single momentary pushbutton, labeled LRN, is used to “teach” the
sensor the color of the target being sensed. With the target in place,
momentarily depress this pushbutton. The yellow LED will flash indicating
that the sensor is “learning” the target. With the release of the pushbutton,
the yellow and red LED will turn OFF indicating a successful learn. If the
yellow LED turns OFF, but the red LED turns ON then the learn was
unsuccessful.
8 Turn Knob
Labeled PRECISION, an 8 position knob is provided to select the desired
level of precision for color discrimination. Turning the knob toward HI
provides the highest level of color discrimination, with lessening degrees
approaching LO.
