Two-Point Static TEACH (Threshold)
 •Establishesasingleswitchingthreshold
 •Thresholdpositionisadjustableusing“+”and“-”buttons(seeManualAdjust,page9)
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10).
Static TEACH and Manual Adjust
Using Manual Adjust with Static TEACH moves the switching threshold.

Contrast Values
500+ Excellent: Very stable operation.
100-500
Good: Minor sensing variables will
not affect sensing reliability.
32-99
Low: Minor sensing variables may
affect sensing reliability.
0-31
Marginal: Consider an alternate
sensing scheme.
