5.4 Wing Sensor Installation
1. The sensor bracket should be oriented forward (ahead of the boom).
2. Typically the best mounting location for the wing sensor brackets will be near the end of
the boom tips, approximately two feet (60cm) from the end.
3. Depending on the boom design, some breakaway sections will lift upwards as they break
back. If the sensor is mounted to this portion of the boom, the system will force the boom
downwards towards the ground as the boom folds backwards.
4. Use the round pipe clamps to fasten the sensor bracket to the TR4(R) boom. Mount the
sensor on the front-side of the boom, in the position as illustrated in Figure 10 and
Figure 11.
5. Ensure the clamps are tight to prevent the bracket from rotating downward.
6. Mount the NORAC ultrasonic sensor into the sensor bracket and run the sensor cable
through the sensor tube.
