Static TEACH
• Establishes a single switching threshold
• Threshold position is adjustable using “+” and “-” buttons (Manual Adjust)
Static TEACH is the traditional setup method, used when two conditions can be
presented by the user. The sensor locates a single sensing threshold (the switchpoint)
midway between the two taught conditions, with the Output ON condition on one side,
and the Output OFF condition on the other (see Figure 2).
The first condition taught is the ON condition. The Output ON and OFF conditions can be
reversed by changing Light/Dark Operate status in SETUP mode (see page 7).
Static TEACH and Manual Adjust
Using Manual Adjust with Static TEACH moves the switching threshold. Sensitivity may
be adjusted at any time when the sensor is in RUN mode by clicking the “+” and “-”
buttons. Each click translates to 1/2 segment on the signal strength light bar. For best
sensing reliability, the light and dark conditions should register equally distant from the
switchpoint on the bargraph display.
NOTES:
1. The sensor will return to RUN mode if either TEACH condition is not registered within 90 seconds. Also, TEACH mode may be cancelled by
pressing and holding the push button for ≥ 2 seconds. In either case, the sensor will revert to the previous conditions taught (i.e., exit without
save).
2. If the sensing conditions are accepted at the end of TEACH Output OFF Condition, the signal strength light bar flashes one of its ten segments
for three seconds to indicate relative sensing contrast. The higher the flashing segment, the higher the measured sensing contrast. High contrast
relates directly to sensing reliability. High-contrast sensing applications are most tolerant of sensing variables, such as web flutter or variations in
color mark color or print density.

Contrast accepted: One light bar segment flashes for
three seconds to indicate relative contrast, and then
sensor enters RUN mode.
Contrast too low: Every other segment flashes for three
seconds to indicate low contrast, and the sensor returns
to TEACH Output ON Condition.
