Automatic Gain Calibration
Before tuning the gain setting, the dead zone for that function must be tuned. If the dead zone tuning has not been
completed, follow the instructions for tuning a dead zone.
1. Follow the, “STEP 1: Prepare the Equipment” on page 24 to “STEP 3: Prepare the Equipment” on page 24 (level booms,
working RPM, etc.), before proceeding.
2. Ensure the AutoHeight panel is in MANUAL mode, at the run screen.
3. Navigate to the "
More ?
" menu prompt in the SETUP menu. Toggle the "AUTO (YES)" switch to confirm.
4. Navigate to the boom section you wish to set up, for example "
Left ?
" to adjust the left up and/or the left down
settings. Toggle the "AUTO (YES)" switch to confirm.
5. Toggle the "SETUP (NO)" switch to access the next menu prompt. Choose the gain up or down setting - see “Table 4 -
Left Channel SETUP Menus” on page 30.
6. Toggle and hold the "AUTO (YES)" switch.
7. When the "
Done
" message is displayed, release the "AUTO (YES)" switch to view the new setting.
Manual Gain Calibration
±
WARNING! This test will drive the boom at full speed in the selected direction for one second. Make sure the boom
has full range of movement, and if driving the boom down, make sure it is not close to the ground.
The purpose of this test is to determine the sprayer boom speeds. It is recommended that you perform each test three times
and average your readings.
1. From the speed measurements taken, use “Table 5 - Right, Left Booms” on page 32 to determine the appropriate gain
values to use for each function. This test will provide approximate results for gain values. Proper gain values rely on
more than just boom speed so it is highly recommended to use the automatic gain setup, if possible.
2. Follow the, “STEP 1: Prepare the Equipment” on page 24 to “STEP 3: Prepare the Equipment” on page 24 (level booms,
working RPM, etc.), before proceeding.
3. Ensure the AutoHeight panel is in MANUAL mode, at the run screen.
4. Navigate to the "
More ?
" menu prompt in the SETUP menu. Toggle the "AUTO (YES)" switch to confirm.
5. Navigate to the boom section you wish to set up, for example "
Left ?
" to adjust the left up and/or the left down
settings. Toggle the "AUTO (YES)" switch to confirm.
6. Toggle the "SETUP (NO)" switch to access the next menu prompt. Choose the gain up or down setting - see “Table 4 -
Left Channel SETUP Menus” on page 30.
7. Toggle and hold the "MANUAL" switch.
8. The valve will turn on at 100 percent speed for exactly one second. The screen will show the actual change in height.
9. The change in height reading is live as long as you hold the "MANUAL" switch. Wait until the height reading has settled
to a stable value and record this reading. This is your boom speed in mm per second (cm/s).
10. Repeat the Manual Gain Test three times, repositioning the boom as necessary.
11. Average your three readings. Typical values are between 40 and 130 cm/sec.
12. Set the Gain value using the "+/-" switch using the tables below as a guideline. Right and left Gain settings are polarized
for direction as shown in “Table 5 - Right, Left Booms” on page 32.
÷
NOTE! Gain values depend on many more factors than just speed and therefore are best set automatically or by an
experienced operator.
÷
NOTE! Test the response at a sensitivity (
Sensi
) of five, because the
Sensi
setting will scale the Gain settings
(“Sensitivity (Sensi) Setting” on page 14). If the booms are not reacting quickly enough, a higher Gain setting will make
the boom respond faster. If the booms are too jerky or unstable, you must lower the Gain setting or improve the
boom's mechanical damping.
