Adjust Mode
Sliding the RUN/PRG/ADJ mode switch to the ADJ position allows the user to perform Expert TEACH/SET methods and Manual Adjustment of the threshold(s).
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 below). The Output ON and OFF conditions can
be reversed by using the LO/DO (Light Operate/ Dark Operate) switch (see LO/DO Switch in Top Panel Interface on page 2).

Two-Point TEACH and Manual Adjust
• Moves switching threshold value up or down to make adjustments
• Slide Mode switch to ADJ to enter Adjust mode
• Press “+” to increase; press “-” to decrease
• GREEN display shows the switching threshold value
• 2 seconds after adjustment, the GREEN display will flash 3 times to con-
firm
• Slide Mode switch to RUN to complete operation
Remember: Manual adjustments are disa-
bled when Auto Thresholds are ON
