Two-Point TEACH
•
Establishes a single switching threshold
•
Threshold can be adjusted using "+" and "-" Navigation key (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 switch point) midway between the two taught conditions, with the Output ON condition on
one side, and the Output OFF condition on the other (see Fig.2).
