Two-Point TEACH
•
Establishes a single switching threshold
•
Threshold can be adjusted using "+" and "-" rocker button (Manual Adjust)
Two-Point TEACH is used when two conditions can be presented statically to the sensor. 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
on page 7).
