1 INTRODUCTION
This booklet is a quick on-site reference for the operator of the UC4+ Spray
Height Control System.
This booklet is intended to be used in conjunction with the:
•UC4+ Spray Height Control System Operators Manual
•UC4+ Spray Height Control System Installation Manual
It is important for the operator to be familiar with the UC4+ Operators
Manual before attempting operation. As well, it is assumed that the operator
is familiar with navigating through the UC4+ control panel menu structure
and with making setting adjustments.
This guide is based on UC4+ software Version 6

2 OPERATOR SAFETY
DANGER
Always ensure that the UC4+ Spray Height Control
system is powered down or in MANUAL mode:
•Before leaving the operator’s seat
•While the machine is not moving
•When transporting the machine
Under no circumstances should any service work be
performed on the machinery while the UC4+ Spray
Height Control system is in the AUTOMATIC mode.
Before working on any part of the booms:
•Set the UC4+ System to MANUAL mode
•Turn the sprayer engine off
Do not operate this system before:
•Reading and understanding the Operators Manual
•Thoroughly understanding your machine operation
The UC4+ Spray Height Control system will greatly
improve your spraying height accuracy and protect the
boom against damage in a wide variety of field conditions.
However, under some circumstances performance may be
limited. The OPERATOR of the sprayer must remain
ALERT at all times and override the automatic control
when necessary. Refer to the warranty statement in
Section 5 for more details.

3 BASIC UC4+ OPERATION
•Upon power-up a sequence of messages are temporarily displayed on
the control panel LCD screen. If the system is running in metric,
METRIC will be displayed briefly on the screen during set up.
- The system is ready for use once the Normal Operating Screen
(Figure 1) is displayed.
•To access either the SENSOR DISPLAY or SETUP menus ensure you
are at the Normal Operating Screen.
- Toggle toward the menu you wish to access.
- Adjust the menu settings using the " +/- " switch while the prompt
is displayed.
•After 30 seconds menu prompts will return to the Normal Operating
Screen.
•To return to the Normal Operating Screen toggle and hold the "SETUP
(NO)" switch for two seconds.
•New settings take effect once the Normal Operating Screen is displayed.

Valve and Air Temperature:
Pressing and holding SETUP will

block temperature (VT) and the air
temperature (AT).
The valve block temperature is
related to the hydraulic oil
temperature.

lost a reading.
The alarm is defaulted OFF.

in the selected units (cm or inches)
•In MANUAL mode the digits represent average actual boom height in
the selected units

3.4 CHANGING TO AUTOMATIC OR MANUAL MODE
•From the Normal Operating Screen toggle the control panel "AUTO"
switch to change between MANUAL and AUTO modes.
•In MANUAL mode, the boom may be controlled as usual with the
boom control switches on the sprayer’s multifunction handgrip.
•Operating the sprayer’s boom control switches while in AUTO mode
immediately causes the boom to revert to MANUAL mode.
•The sprayer’s joystick switches override automatic height control on
either the left, right, or both sides
•To return to AUTO mode the "AUTO (YES)" switch must be activated.
•The target average height (Section 3.5) can be adjusted by momentarily
pressing the sprayer’s main lift control switches (main up or main
down).
•Pressing and holding the sprayer’s main up or down switches for more
than two seconds reverts ALL booms (left, right, main and roll) to
MANUAL mode. This is a convenient method for switching to
MANUAL mode when folding for transport
3.5 ADJUSTING THE SETPOINT
The system is in AUTO and can have the
target average height (setpoint) adjusted.
•Use the " +/- " switch in AUTO mode to adjust the target height setting.
•Alternately, adjust the main boom target height by momentarily pressing
the sprayer’s main lift control switch while in AUTO mode.
•Each press of the up/down switch increases/decreases the target height
by one selected unit (cm or inches), respectively
•The smallest target height setting is called the minimum height override.
•Default minimum height settings are factory programmed before
shipping.

3.6 VIEWING THE ACTUAL BOOM HEIGHT
•Toggle the "SENSOR DISPLAY" switch to view actual boom heights.
•The left, right, and main (center) boom heights are each displayed on a
separate screen. If there are 2 sensors on each wing, both sensor heights
will be displayed on the same screen. If only one sensor is mounted on
each wing (standard), only one height reading will be present on each
screen.
Left boom outer sensor (LO) is at 91 and the
left boom inner sensor (LI) is at 82.
Right boom outer sensor (RO) is at 88. In this
case it is the only sensor on the right boom.
Center section height is 90.
•To lock the currently viewed sensor heights on the screen indefinitely
toggle the " +" switch once.
•Height menus can be viewed in both AUTO and MANUAL mode.
•More information on sensor height menus is available in the UC4+
Operators Manual.

3.7 CHANGING THE SYSTEM SENSITIVITY
A sensitivity setting of 5 (default setting).
•Toggle the "SETUP” switch to view the current Sensi setting.
•While viewing this menu, toggle the " +/- " switch to adjust the
Sensi value.
•Lower numbers reduce system sensitivity and improve stability.
•Increasing the number will increase the response of the system (five is
the default setting).
•If the Sensi setting is modified, the panel will return to the Normal
Operating screen after 3 seconds.
•A lower Sensi setting may be required for stable control at the start
of operation (before sprayer is warmed up).
•As the sprayer warms up increase the Sensi setting until the
performance reaches an optimum level.
•Refer to the UC4+ Operators Manual for a discussion of performance
issues
3.8 CHANGING BETWEEN SOIL AND CROP MODE
System is in CROP mode
System is in SOIL mode
•SOIL or CROP mode can be adjusted in both MANUAL and AUTO
modes.
•To view the current setting, toggle the "SETUP (NO)" switch twice.
•While viewing this menu, use the " +/- " switch to change between
SOIL and CROP mode.
•Wait five seconds for the change to take effect on all sensors.
•If the mode is modified the panel will return to the Normal Operating
screen after 3 seconds.

3.9 PERFORMING A RETUNE
NOTE: Sensors are not adjusted or calibrated by performing a
ReTune. A retune recalibrates hydraulic valve parameters.
3.9.1 Perform a system ReTune when:
•When a hydraulic solenoid valve is changed.
•When the hydraulic pump is changed or adjusted.
•When the normal working temperature of the hydraulic oil has shifted
significantly from when the system was previously calibrated.
•If you are running a pull type sprayer and use different tractors to
operate the sprayer, you should perform a ReTune each time the tractor
is changed.
•If you have a flow control for the boom hydraulics, set it prior to
tuning. If you change the flow setting by more than 20 percent, you
should perform a ReTune.
3.9.2 Before starting a ReTune:
•Unfold the sprayer in a location that is relatively level, and where the
sensors are over bare soil or gravel.
•Check the pads between the sprayer boom and the boom carrier frame
to ensure no friction because of wear. Use grease or other lubricants, if
necessary.
•Start the solution pump and run the sprayer’s engine at a normal
working RPM for the entire setup.
3.9.3 Performing a ReTune:
•Navigate to the "ReTune?" menu prompt in the SETUP menu.
•To start a ReTune, confirm with the "AUTO (YES)" switch.
•Follow the instructions on the LCD screen.
NOTE: The booms are to be leveled at a normal working height when
ReTune starts – it is not necessary to set them to 35 inches. The
35 inch height is only required during the Automatic/Manual
System Setup.
