CH1 Analog Output
Two-Point TEACH
• Establishes defined endpoints for the analog output range
• Analog endpoints can be adjusted by using the "+" and "-" rocker button (Manual Adjust)
Two-Point TEACH is used when two conditions can be presented statically to the sensor. The first taught condition is set to
0 V (4 mA), and the second taught condition to 10 V (20 mA). The order of the taught points determines the slope. If the
first taught condition is darker, the slope will be positive. If the first taught condition is lighter, the slope will be negative.
Reverse the slope of the analog output by changing the AOut SLPE menu setting.
NOTE: Depending on the application configuration and fibers used, the analog function may or may not
behave linearly. The received light intensity will be dictated by the inverse square properties of light.

One-Point SET
• Defines the 5 V (12 mA) midpoint of the analog output
• Analog midpoint can be adjusted by using the "+" and "-" rocker button (Manual Adjust)
A single sensing condition is presented, and the sensor positions the midpoint of its analog range (5 V or 12 mA) exactly at
the presented condition. The size of the window is determined by the OFSt Pct1 menu setting. The slope of the analog
output is determined by the AOut SLPE setting.

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