3 Control Panel Mounting
Install the UC4+ Control Panel (E01) in the cab of the sprayer or tractor with the supplied
mounting bracket. The location must facilitate connecting the power cable (C10) to the bottom
of the UC4+ Control Panel.
Using Item B06 together with the adjustable RAM mount on the control panel (E01), mount
panel to the HARDI controller bracket, as shown in Figure 1.

Figure 2: Cable Routing Overview
1. Connect C10 to the UC4+ Control Panel in the sprayer cab. Ensure that both plugs (P16A
and P4) are connected to the panel.
2. Route the receptacle end (R16) of C10 to the exterior of the cab and connect to C11 at the
hitch. Ensure cable is routed in a safe manner to avoid damage.
3. All other cables and connections shown are factory installed – they are illustrated in Figure 2
for reference only.

5 Calibration
5.1 Initial Power Up
1. Turn on the power for the UC4+ Control Panel using the switch on the side of its chassis.
Ensure that the UC4+ display lights up to confirm that the panel has +12 volt power.
2. After a moment the panel will display the Main Run Screen:
5.2 ReTune
1. For optimal performance, the UC4+ Height Control System must be calibrated to the tractor
unit powering the sprayer hydraulics. Before you start calibrating the hydraulics ensure you
complete the following steps:
•Unfold the sprayer in a location that is relatively level, and where the sensors are over
bare soil or gravel. Do not conduct the setup procedure over standing crop, or tall
weeds/grass.
•Ensure the boom roll suspension system is functioning properly and smoothly. Friction
on wear surfaces can be relieved using lubricants (grease, etc) or adjustment. Properly
tuned suspension systems will optimize UC4+ performance.
•For best results, the hydraulic system should be under a normal load and at a normal
working temperature. Start the solution pump and run the sprayer’s engine at a normal
working RPM for the entire setup. Cycle all boom sections up and down manually for
five minutes to warm the oil. Ensure any hydraulic flow controls are adjusted for normal
field operation. Changing the hydraulic flow controls after or during the system setup
will affect the UC4+ performance.
2. To initiate the “ReTune” process, navigate from the Main Run Screen to the “ReTune” menu.
Ensure the UC4+ control panel is in manual mode, at the run screen.
3. Toggle "SETUP" until the display shows "Retune?". Toggle "AUTO (YES)" to confirm.
4. The panel will start the “ReTune” process. Follow the on-screen prompts. Additional
information concerning the “ReTune” procedure may be found in the UC4+ Operator’s
Manual.
5. After you have completed the “ReTune”, you will need to manually calibrate the deadzone
and gain for the slant valve (Section 5.3).

5.3 Calibrating the Slant Valve
The roll (slant) valve can only be calibrated manually as described below. When calibrating the
roll valve you must first calibrate the deadzone clockwise and counter clockwise settings and
then the gain clockwise and counter clockwise settings.
Navigating to the Slant Valve Settings:
1. Ensure the UC4+ control panel is in manual mode, at the run screen.
2. Toggle "SETUP" until the display shows "More?". Toggle "AUTO (YES)" to confirm.
3. Toggle "SETUP" until the display shows "Roll?". Toggle the "AUTO (YES)" switch to
confirm.
4. Toggle the "SETUP" switch to access the next menu prompt or toggle "SENSOR DISPLAY"
to access the previous menu. Choose the dead zone up/down or gain up/down setting
(Figure 3).

Manual Dead Zone Calibration:
1. Follow Section 5.2 Step 1 (level booms, working RPM, etc.) before proceeding.
2. Choose the dead zone up or down setting (Figure 3).
3. Press and hold the "MANUAL" switch.
4. The valve will turn on at the indicated setting for exactly one-second. The screen will show
the actual change in height.
5. 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.
6. Average three readings. The acceptable average change in height should be from 20 to 50
mm.
7. If the average is less, increase the DZ setting with the "+/-" switch. If the average is more,
decrease the DZ setting with the "+/-" switch.
8. Repeat Steps 3 to 7 until the average falls within 20 to 50 mm.

Manual Gain Calibration:
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.
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. From the speed measurements taken,
use Table 1 to determine the appropriate gain values to use for each function.
1. Follow Section 5.2 Step 1 (level booms, working RPM, etc.) before proceeding.
2. Choose the gain up or down setting (Figure 3).
3. Press and hold the "MANUAL" switch.
4. The valve will turn on at 100 percent speed for exactly one-second, regardless of the value of
the gain setting. The screen will show the actual change in height.
5. 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 inches per second (in/s) or mm per second (mm/s).
6. Repeat Steps 3 to 5 three times, repositioning the boom as necessary. Average your three
readings.
7. Set the gain value using the "+/-" switch using Table 1 below as a guideline.
Function Boom Speed (mm/sec) Gain Setting
Roll >2200 1
Roll 2200 - 1000 1 - 5
Roll 1000 - 400 5 - 9
Roll 400 - 100 9 - 11
Roll <100 11 - 12
