Figure 1 illustrates the general layout of the UC4.5 system components:
Figure 1: General UC4.5 System Layout
Do not use high speed power tools/drills when installing hardware.
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 to all threaded parts upon installation.
Permatex Anti-seize lubricant is preferred, but other similar anti-seize products
may be used.

4Pre-Install Checklist
The pre-install checklist is necessary to check the existing sprayer functionality before the
installation.
1. Unfold the sprayer over a flat, unobstructed area (i.e. no power lines…etc.).
2. Ensure all boom-fold operations are functional (place a check mark in boxes below).
3. Bring engine to field-operational RPM and record below.
4. Record the time (seconds) it takes for a full stroke for all boom functions. To ensure
repeatable measurements, take the average of 3 trials.
5. Not all sprayers will have the functions listed below in Figure 4.
Ensure the boom has sufficient travel so it does not contact the ground during
these tests.
Figure 4: Pre-Install Boom Speeds

5Ultrasonic Sensor Installation
5.1 Ultrasonic Sensor Serial Number Arrangement
When installing the 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 sensor has a serial number
stamped on the sensor housing.
Apply a light coating of the supplied Permatex Anti-seize grease to all threaded parts upon
installation.
Figure 5: Sensor Serial Number Arrangement

5.2 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.

10
5.3 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 sensor bracket onto the boom using the U-bolts provided (B01).
5. 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.
Figure 7: Bracket Mounting Example

11
5.4 Rainflap Installation
Rainflaps are only installed in the wing sensor brackets and are not installed for
120’ booms.
1. Insert one side of the rainflap rod into the pre-bent hinge tab on the sensor bracket.
(Figure 8)
Figure 8: Rainflap Rod in Pre-Bent Hinge Tab
2. Align the other side of the rainflap rod with the unbent hinge tab. (Figure 9)
Figure 9: Align Rainflap Rod
3. Bend the hinge tab inward over the rainflap rod until the hinge tab fits securely in the detent
groove on the backside of the sensor bracket. (Figure 10)
Figure 10: Bend Rainflap Hinge Tab
4. Ensure the rainflap actuates smoothly when the bracket is turned upside down and returns
to the open position when the sensor bracket is returned to its operating position (sensor
pointing downwards toward the ground).

6Roll Sensor Installation
6.1 Bracket Assembly
1. Securely mount the roll sensors to the included roll sensor brackets using the #6 machine
screws. Tighten screws to 10 in-lbs (1.1 Nm).
2. The orientation of the mounted roll sensor to the roll sensor bracket will depend on the
bracket mounting. The roll sensor CANbus connector must be pointing towards the right
side of the sprayer (when looking from the rear of the sprayer).
Figure 11: Mounting Roll Sensor to Bracket
Figure 12: Roll Sensor Orientation - Connector Facing Right Wing

6.2 Roll Sensor Mounting Guidelines
1. When mounting the roll sensors, mount the roll sensor without the temperature probe on
the boom frame and the roll sensor with the temperature probe on the chassis.
Figure 13: Roll Sensor and 8-Way Coupler Mounting
2. Ensure the roll sensors are relatively level when the sprayer boom and chassis are level.
3. Both roll sensor cables should be pointing towards the right hand wing of the sprayer.
4. Ensure both roll sensors are mounted adequately and that the cables provide enough slack
to allow sufficient boom roll.

6.3 Temperature Probe
Once the block is mounted, fasten the temperature probe from E03 to the NORAC valve
block using the included 3/8x1/2” bolt as illustrated in Figure 14.

7Electrical Installation
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. 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 are available at your
local outdoor store as a RAM mount part number RAM-B-236. (See http://www.ram-
mount.com/)
Figure 15: Cable Configurations: C10, C11 and C30
2. Connect the UC4.5 power cable (C10) to the UC4.5 Control Panel in the cab. Ensure that
both plugs (P16 and P4) are connected to the panel. Cable tie C10 to the RAM mount to
help provide strain relief.
3. Connect cable C30 to P6A of C10 using a 2-way coupler (E12). Connect C30 to an
appropriate power supply.
Ensure the UC4.5 Control Panel’s power is OFF for the remaining installation.
(Bottom of switch pressed IN).
4. Route the P12/P6 of C10 out of the cab.
5. Connect P12/P6 to R12/R6 of the extension cable (C11) outside of the cab.
6. Run cable C11 to the rear of the sprayer, in the vicinity of the valve block.

16
Figure 16: Cable Configurations: C03, C11, C12, C13 and C16
7. Connect the 3-pin tower (T3) on cable C16 to S3 on C11.
8. Insert the 2-pin tees (S2A-T2A - S2D-T2D) of C16 between the matching valve connections
(Left Up, Left Down, Right Up, Right Down) on the sprayer valve block.
9. Connect the 6-pin shroud on cable C12 to T6 on C11.
10. Insert the 2-pin tees (S2A-T2A and S2B-T2B) of C12 between the matching valve
connections (Main Up, Main Down) on the sprayer valve block.
11. Connect the 3-pin shroud (S3) on cable C13 to T3 on C11.
12. Insert the 2-pin tee of C13 between the bypass valve connection on the sprayer valve block.

13. Connect the valve interface cable (C03) to connector S6 on the valve extension cable
(C11).
14. Connect the 2-pin connectors on the valve interface cable to the NORAC valve block, as
shown in Figure 18.
15. The connectors on the valve cable (C03) are marked RIGHT UP, LEFT UP, RIGHT
DOWN and LEFT DOWN. Cables labeled with UP go on the same side as the
hydraulic hoses.
Figure 18: Valve Cable Connections
16. Fasten the 8-way coupler to the boom with cable ties as shown in Figure 13. Connect P6
on C11 to the 8-way coupler.
17. Connect the boom frame roll sensor to the 8-way coupler.
18. Connect the chassis roll sensor (temp. probe) to the 8-way coupler using cable C01 and a
2-way coupler (E12).
19. Connect two cables (C05) to the 8-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.
20. 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 2-way coupler. Plug the sensor and the
CANbus cable into the 2-way coupler.
21. Insert the 6-pin plugs (P03) into the remaining connections on the 8-way coupler.
IMPORTANT:
Provide enough slack in all cables to account for the movement of the main
section, parallel lift, and FOLDING boom movement.
