3.
Navigate to the boom section you put the sensor on, for example, "
Left ?
", if the sensor is mounted on the left
hand boom. Toggle "AUTO (YES)" switch.
4.
Navigate to the boom location you mounted the sensor on, for example, "
LO
" for the left outer sensor. This screen will
show the previously installed sensor serial number (if any) as shown in Table 3.
5.
Toggle the "+" switch once to search for all the connected sensors.
6.
Use the "+" switch to toggle through a list of available sensor serial
numbers. Sensor height reading is shown beside the serial
number.
7.
When the desired serial number is shown, toggle "AUTO (YES)" switch to confirm.
8.
Proceed to "
LOht
" menu prompt to check/calibrate the sensor's height reading (see next section).
9.
Toggle and hold "SETUP (NO)" or “SENSOR DISPLAY” switch for two seconds to return to the run screen.
Calibrating the Sensor's Height Reading (Zero Height)
1.
Ensure the sprayer boom is unfolded and the sensors are located
over bare soil or gravel. Position the boom at a normal working
height. Do not conduct this procedure over standing crop or tall
grass/weedy areas.
2.
Using a tape measure, measure the distance from the bottom of
the spray nozzle closest to the sensor to the ground. Round this
measurement to the nearest cm.
3.
Ensure the AutoHeight control panel is in manual mode, at the run
screen.
4.
Navigate to the boom section you put the sensor on, for example,
"
Left ?
", if the sensor is mounted on the left boom. Toggle
"AUTO (YES)" switch.
5.
Navigate to the location you measured, for example, "
LOht
" for
the left outer sensor menu prompt as described in “Table 3 - Left
Channel SENSOR DISPLAY Menus” on page 28.
6.
If the currently displayed height reading is not correct, adjust it
using the "+/-" switch. The " + " switch will increase the reading, the
" - " switch will decrease the reading.
7.
To return to the run screen, toggle and hold "SETUP (NO)" or “SENSOR DISPLAY” switch for two seconds.
÷
NOTE! To view the absolute height reading from the sensor to the ground, press and hold the “AUTO (YES)” switch
from the “
LOht
” menu. This height reading can be useful for troubleshooting purposes.
Setting Up Hydraulic Valves
Each valve must be tuned correctly for optimum performance from the AutoHeight system. When setting up the valves, the
sprayer booms must have room to move in their full range of motion. Make sure there are no obstructions, such as power
lines, that the booms may come into contact with.
Before setting up the valves manually, it is recommended you attempt the automatic install. Starting the automatic install
will load the default valve settings, which will make the manual valve setup much simpler. At any time the automatic install
can be cancelled and the default settings are still stored.
Each valve has two settings; dead zone and gain. The dead zone relates to the smallest amount of movement the valve can
produce. The maximum boom speed is dependent on the gain.
A dead zone and gain parameter exists for each valve. Each valve may be tuned:
•
Automatically (as part of the automatic install or retune).
•
Automatically (one valve at a time).
•
Manually.
÷
NOTE! You do not need to run both the AUTO and Manual tests. The tests are entirely independent.
The left channel menu prompts are shown below. For other channels, the basic structure and behavior of the prompts are
the same.
