4 Calibration
4.1 Initial Power Up
Turn on the power for the UC4.5 Control Panel using the switch on the side of its chassis.
Ensure that the UC4.5 display lights up to confirm that the panel has +12 volt power.
After a moment the panel will display the Main Run Screen:
4.2 ReTune
1. For optimal performance, the UC4.5 Height Control System must be calibrated to the
tractor unit powering the sprayer hydraulics. Before calibrating the hydraulics, ensure
following steps are complete:
 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 UC4.5 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 UC4.5 performance.
2. To initiate the “ReTune” process, navigate from the Main Run Screen to the “ReTune”
menu. Ensure the UC4.5 control panel is in manual mode and at the run screen.
3. Press until the display shows "Retune?". Press 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 UC4.5 Operator’s
Manual.
5. After the “ReTune” is complete, manually calibrate the deadzone and gain for the slant valve
(Section 4.3).
