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 half-inch.
3.
Navigate to the "
LOht
" menu prompt as described in the
previous section.
4.
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.
5.
To return to the Normal Operating Screen, toggle and hold
"

Option
s
for Main Boom Sensor in Wheel Track
Mounting the main boom sensor directly behind a sprayer tire may impair
main lift control when operating in
CROP
mode. Height readings from crop
that is flattened by the sprayer wheel do not provide an accurate
measurement of canopy height, resulting in poor performance (
Section
5.2.4
). Two possible solutions are explained below.
A.
Turning the Main (Center) Section Off
This workaround will disable the main section’s
AUTOMATIC
control;
however, manual height readings from this section will still be available.
The sprayer’s wing booms will still be controlled automatically. Perform the
following procedure:
1.
Ensure the UC4+ control panel is in
MANUAL
mode, at the Normal
Operating Screen.
2.
Navigate to the "
More ?
" prompt in the
SETUP
menu. Toggle
"
AUTO (YES)
" switch.
3.
Navigate to the "
Main ?
" prompt in the
SETUP
menu. Toggle
"
AUTO (YES)
" switch.
