Window Limits
Window limits may be taught to the sensor in several ways. The following methods
describe the TEACH procedures for programming using the sensor push buttons;
remote programming (remote TEACH) procedures are described on page 7.
Teaching Limits for Either Analog or Discrete Output
1. Choose the output for the first set of window limits (analog or discrete) and push
and hold the corresponding button until the tri-color TEACH LED turns ON
(solid). This indicates the sensor is waiting for the first limit: red for analog
output, or green for discrete output.
2. Position the target for the first limit and briefly “click” the same button. This will
teach the sensor the first limit. The TEACH LED will flash at 2Hz to acknowledge
receiving the first window limit; it is now waiting for the second limit.
3. Position the target for the second limit and “click” the button again. This will
teach the sensor the second limit. The TEACH LED will turn OFF to indicate that
the sensor will now function in normal RUN mode.
4. Repeat for the opposite output (analog or discrete) if a second output is desired.
Teaching Analog Limits Using the Auto-Zero Feature (Analog Output)
For some analog applications, a sensing distance set point centered within a sensing
window may be required. The TEACH procedure is simple: teaching the same limit
twice causes the sensor to program a 10 mm wide window centered on the position
taught (position ±5 mm).
Teaching Fixed-Field Sensing Mode (Discrete Output)
Teaching the same limit twice creates a sensing window with the far limit at the teach
distance and the near limit at the minimum operating range of the sensor
(approximately 44 mm).
Teaching Limits for Both Analog and Discrete Outputs Simultaneously
If you want both your discrete and analog outputs to be set at exactly the same limits,
you may set both simultaneously.
1. Push and hold either the Analog or the Discrete programming push button until
the tri-color TEACH LED turns ON. “Click” the other button (Analog or Discrete).
The TEACH LED turns Yellow. The sensor is waiting for the first limit.
2. Position the target for the first limit and “click” either TEACH button. The TEACH
LED will flash at 2Hz, alternating red and green, to acknowledge receiving the
first window limit; it is now waiting for the second limit.
3. Position the target for the second limit and “click” the buttons again to teach the
sensor the second limit. The TEACH LED will turn OFF to indicate that the sensor
will now function in normal RUN mode.
