ANTI-SEIZE LUBRICANT KIT 1
The use of dielectric grease is not recommended on any NORAC electrical
connections.
To ensure all stainless steel hardware does not gall or seize apply a light coating of
the supplied Permatex Anti-seize grease (M06) to all threaded parts upon
installation. Permatex Anti-seize lubricant is preferred, but other similar anti-seize
products may be used.

4Ultrasonic Sensor Installation
4.1 Ultrasonic Sensor Serial Number Arrangement
When installing the UC5 sensors, start with the smallest serial number on the left-hand side,
and proceed to the largest serial number on the right hand side. Each UC5 sensor has a serial
number stamped on the sensor housing.
Apply a light coating of the supplied Permatex Anti-seize grease (M06) to all
threaded parts upon installation.

4.2 Ultrasonic Sensor Mounting Guidelines
The following guidelines will ensure optimal sensor performance and prevent sensor
measurement error. These rules should be followed for both the wing sensors and the main
lift (middle) sensor.
1. In its lowest position, the sensor must be 9 inches (23 cm) or more from the ground.
2. Ensure that there are no obstructions within a 12-inch diameter circle projected directly
below the center of the sensor.
3. The sensor should be approximately vertical at normal operating heights.
Figure 5: Sensor Mounting Guidelines

7
4.3 Low Profile Bracket Mounting Guidelines
1. Minimize the distance between the bolts to prevent bending the bracket and prevent the
bracket from loosening over time.
2. Ensure the bracket is mounted tight against the bottom of the boom, minimizing the
distance between the boom structure and the angled flange.
Figure 6: Bracket Mounting Guidelines
A problem can arise if a sensor is not mounted correctly. It is possible for the
sensor to read off of the boom instead of the ground. This may only become
apparent once the control system is switched from soil to crop mode.
Also be careful that the sensor bracket does not collide with any other part of the
boom when the boom is folded to transport position. If possible, mount the sensor
brackets while the booms are folded to ensure they will not cause interference.

8
4.4 Wing Sensor Installation
1. The sensor bracket should be oriented forward (ahead of the boom).
2. Typically the best mounting location for the wing sensor brackets will be near the end of
the boom tips, approximately two feet (60cm) from the end.
3. Depending on the boom design, some breakaway sections will lift upwards as they break
back. If the sensor is mounted to this portion of the boom, the system will force the boom
downwards towards the ground as the boom folds backwards.
4. Mount the NORAC ultrasonic sensor into the sensor bracket and run the sensor cable
either through hole in the back or through the side cut-out and behind the bracket. Ensure
the cable is clear of moving parts and will not be damaged during folding.

5Electrical Installation
Not all cables required are included in this kit. Consider building your own
cables or refer to the NORAC Generic Cable Ordering Guide to order the
necessary cables.
While installing the electrical parts, refer to Section 8 for identification of
cables and connectors.
1. Install the UC4.5 Control Panel (E01) in the cab of the sprayer. Mount the panel where it
will be clearly visible and within easy reach of the operator.
A good spot to mount the UC4.5 control panel is on the right hand side of the cab to the
Roll Over Protection Bar (ROP). Four pilot holes for the screws provided need to be
drilled to facilitate the control panel mounting.
Another option is to purchase an adapter for the flexible panel mount that has a 3/8" NC
threaded stud on the end to bolt through an existing mount. These can be found at your
local outdoor store as a RAM mount part number RAM-B-236. (See http://www.ram-
mount.com/)
Figure 8: UC4.5 Power and Valve Extension Cables
2. Connect the UC4.5 power cable (C10) to the UC4.5 control panel in the sprayer cab.
Ensure both plugs (P16 and P4) are connected to the panel. Cable tie C10 to the RAM
mount to help provide strain relief.
Ensure the UC4.5 control panel’s power is OFF for the remaining installation
(Bottom of switch pressed IN).
3. Connect the power cable connector (P6A) to an auxiliary power connection in the sprayer.
If an appropriate connector cannot be found, it may be necessary to cut off the connector
and splice into the existing wiring.
For a clean connection to the sprayer’s power supply, NORAC provides
optional power interface cables. Please see NORAC Cable Ordering Guide for
details.

10
4. Route the P12 and P6B of C10 out of the cab.
5. Connect the 12-pin and 6-pin Deutsch plugs (P12 and P6B) of the power cable (C10) to
R12 and R6 of C11 on the outside of the cab.
For a pull type sprayer, connect at the hitch. This connection will provide the
hitch disconnect.
6. Route C11 to the vicinity of the valve block at the rear of the sprayer.

7. Connect the 6-pin shroud (S6) on the generic interface cable (C12) to the mating 6-pin
tower (T6) on C11.
8. Connect the 3-pin tower (T3) on the roll interface cable (C16) to the mating 3-pin shroud
(S3) on C11.
9. If there is an enable valve on the sprayer block, connect 3-pin shroud (S3) of C13 to T3 on
C11.
10. Route the free ends of C12, C16 and C13 to the existing valve block.
11. Splice the loose wires of C12, C16 and N1C of C13 into the existing wiring to tee in to
appropriate functions of the sprayer’s control system.
The following wires are not used for this installation:
C12: N1D, N1E, N1F, N1G
C13: N1A, N1B
See UC4.5-BC-CABLE-GUIDE cable ordering guide for more information.
12. Fasten the 3-way coupler to the boom with cable ties. Connect P6 on C11 to the 3-way
coupler.
13. Connect two cables (C05) to the 3-way coupler and route along the booms to the wing
sensors. Follow existing cables and hoses to be sure the cable will not be pinched or
stretched.
14. At the sensor brackets, attach a 2-way coupler with terminator (E20) to the sprayer boom.
The 2-way coupler with terminator is the white two way coupler. Plug the sensor and the
CANbus cable into the 2-way coupler.
IMPORTANT:
Provide enough slack in all cables to account for all boom movement and
FOLDING boom movement.

6Software Setup
1. Start up the sprayer and test the sprayer’s functionality. The control panel does not need
to be powered on for the original boom function switches to operate. Unfold the booms
and raise/lower each boom and the main section.
Confirm that the cabling and hoses are agreeable to the entire range of motion.
2. If any functions do not work, review the hydraulic and electrical portions of this manual to
check for proper installation.
3. Turn on the power for the UC4.5 Control Panel using the switch on the side of its chassis.
4. Begin the AUTOMATIC SYSTEM SETUP procedure as described in the UC4.5 Spray
Height Control Operator’s Manual (M01).
Performance may be limited during the Control System Test in the
Automatic Setup since the slant valve has not been calibrated yet. It is
recommended to repeat the control system test again after the slant valve
has been calibrated.
5. After the AUTOMATIC SYSTEM SETUP, manually calibrate the slant valve as described in
Section 7.
6. For optimal performance of the UC4.5 system, there should be very little play at the hitch
clevis. The addition of polymer washers can help tighten up this connection (Figure 11).
Figure 11: Hitch Point

7Calibrating the Slant Valve
There are two key settings for each valve direction. These settings are valve DeadZone, "DZ",
and valve GAIN, "KP".
The DeadZone ("DZ") setting represents the size of electrical signal required at the solenoid
valve to cause a boom speed of one inch per second (Section 7.1).
The GAIN ("KP") setting is inversely related to the maximum speed of the boom. That is, the
faster the boom the lower the GAIN setting (Section 7.2).
IMPORTANT:
Before setting up the slant valve, ensure the following steps are complete.
1. 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.
2. 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. This is important and
will increase the UC4.5 Spray Height Control system performance significantly.
3. Start the solution pump and run the sprayer’s engine at a normal working RPM for the
entire setup. Make sure that the height of all the booms can be manually adjusted. For best
results, the hydraulic system should be under a normal load and at a normal working
temperature. An effective way to warm the oil is to cycle all boom sections up and down
manually for 5 minutes. Longer warm up times may be required in cold weather. For pull-
type sprayers, ensure any hydraulic flow controls are adjusted for normal field operation.
Changing the flow controls during or after the setup will affect the UC4.5 operation.

7.1 Valve DeadZone Test
1. Ensure the UC4.5 control panel is in MANUAL mode at the Normal Operating Screen.
2. Navigate to the "More ?" menu prompt in the menu. Press to confirm.
3. Navigate to the roll section. Press to confirm.
4. Press switch to access the next menu prompt, in this case the roll CW DeadZone
(" DZ "). Press and hold .
5. The valve will turn on at the indicated setting for a short amount of time based on the value
of the DZ setting. A larger setting will turn the valve on for a longer period of time. The
LCD screen will show the actual change in height.
Ensure the boom moves in the clockwise direction (left boom up, right boom
down). If the boom moves in the opposite direction, check the wiring and/or
hydraulics for an installation error.
6. The change in height reading is live as long as is held. Wait until the height reading has
settled to a stable value and record this reading.
Some sprayers may exhibit unwanted movement in the boom due to
mechanical play. This may cause some of the tests to show no movement at
all if the mechanics of the boom are loose. It is recommended to take at
least five readings to ensure the tests are accurate.
7. Average the five readings. The acceptable average change in height should be from 13 to 38
mm (0.5 to 1.5 inches) (ideal would be 25 mm (1 inch) exactly).
8. If the average is less, increase the DZ setting with using . If the average is more,
decrease the DZ setting using .
9. Repeat the Dead Zone Test until the average falls into the acceptable range.
10. When satisfied with the DeadZone roll clockwise test (" DZ "), repeat this test for the
roll counter clockwise (" DZ ").

7.2 Valve Gain Test
1. Ensure the UC4.5 control panel is in MANUAL mode, at the Normal Operating Screen.
2. Navigate to the "More ?" menu prompt in the menu. Press to confirm.
3. Navigate to the roll section. Press to confirm.
4. Press twice to access the roll CW GAIN (" KP ") menu prompt.
Before continuing make sure the boom has room to move at full speed for
one second. Ensure the main lift is up to allow room for the boom to move.
5. Press and hold .
6. The valve will turn on at 100 percent speed for exactly one-second. The LCD screen will
show the actual change in height.
7. The change in height reading is live as long as is held. Wait until the height reading has
settled to a stable value and record this reading. This is the boom speed in mm per second
(mm/s) or inches per second (in/s) if inches is the selected units.
8. Repeat the Manual Gain Test three times, repositioning the boom as necessary.
9. Average the three readings
10. Set the Gain value using the buttons. Use the following table as a guideline.
