Setup Procedure for Tunnel Train Detection
1. Mount the sensor such that Y is 1/3 of X, and align the sensor so the center of the
beam strikes the corner of the tunnel beyond the far rail, as shown in Figure 4.
2. Make sure the area between the sensor and the background is clear, and press the
TEACH button until the Output LEDs turn ON red.
3. Align the sensor. The red Signal LED will flash faster as alignment improves; solid ON
is best.
4. Press the TEACH button again. The Output LEDs turn OFF, and the red Signal LED
turns ON.
5. Verify proper setup by blocking the beam. The Output LEDs should turn ON yellow.
