Sensor Alignment
Proper sensor alignment is critical for proper AutoHeight performance.
The majority of problems reported by operators in the field are due to
improper sensor mounting.
1. When the boom is at its lowest position, the sensor mouth must be
25 cm or more above the spray nozzles.
2. The bottom of the sensor must be at least 25 cm in front of the
nozzles.
3. The sensor must be approximately vertical at normal operating
heights.
4. Ensure that there are no obstructions within a 30 cm diameter
circle projected directly below the sensor.
5. When mounting or relocating sensor brackets, ensure they do not
interfere with boom folding operation.
6. When mounting to the top part of the boom (as shown in Figure
10), check that the sensor cannot read off the bottom part of the
boom. This is most common in CROP mode.
