Example:
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 Bracket Assembly
Assemble the breakaway sensor bracket as illustrated in Figure 5, following the instructions
below.
Figure 5: Breakaway Bracket Assembly
1. Compress the spring and insert it together with the collar into the base.
2. Slide the tube through the assembled part.
3. Using the bolt and nut, tighten the collar to the tube with the sensor tube centered.
4. Apply a small amount of grease to the rotating surfaces of the bracket.

5.2 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 6: Sensor Serial Number Arrangement

5.3 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 (A).
2. The centerline of the acoustic cone should be approximately vertical at normal operating
heights (A).
3. The bottom of the sensor must be at least 9 inches in front of the spray nozzles and boom
structure (B). (This does not apply for the main lift sensor)
4. The bottom of the sensor must be at least 9 inches above the spray nozzles (C).
5. Ensure there are no other obstructions with a 12 inch (23 cm) diameter circle projected
directly below the sensor (D).
Figure 7: Sensor Mounting Guidelines
Figure 8: Sensor Reading Off Boom

11
5.4 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. Fasten the sensor bracket to the round tube structure using the supplied round clamps
(B15).
5. Mount the NORAC ultrasonic sensor into the sensor bracket and run the sensor cable
through the sensor tube.
Figure 9: Wing Sensor Mounting (80ft Boom)
Figure 10: Wing Sensor Mounting (60ft Boom)
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.

6Roll Sensor Installation
For this installation, the roll sensor is only being used for temperature
compensation.
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).
Figure 11: Mounting Roll Sensor to Bracket
2. Attach the roll sensor and roll sensor bracket to the boom, near the NORAC valve block
using the provided cable ties.
3. 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 12.
Figure 12: NORAC Valve Block with Temperature Probe Installed

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 can be found at your
local outdoor store as a RAM mount part number RAM-B-236. (See http://www.ram-
mount.com/)
Figure 13: Cable Configurations: C10 and C03
Figure 14: Access Plate Under Dash

Figure 15: Access Hatch in Front of Seat
2. Route cable C10 into the cab into the cab. Ensure that the cable is not wrapped around the
drive shaft beneath the sprayer.
3. The access hole can be located either beneath the dash (Figure 14) or in front of the seat
(Figure 15). There is a removable access plate beneath the dash (on the left, towards the
door). A slot may be cut in the access plate so that it can be replaced (Figure 14). It is
recommended to use a rubber grommet in the cutout slot to avoid cable damage.
4. Connect C10 to the UC4.5 Control Panel (E01) in the sprayer cab (Figure 13). Cable tie
C10 to the RAM mount to help provide strain relief.
Ensure the UC4 Control Panel’s power is OFF for the remaining installation
(Bottom of switch pressed IN).
5. Connect the ring terminal connections on C10 to a 12V source.
6. Route C10 to the back of the sprayer.
7. Route the end of C10 with the 2-pin Deutsch and 2-pin weatherpack connectors to the
SpraCoupe Bypass/Jam valve (Figure 16).
8. Disconnect the SpraCoupe 2-pin connectors at the Bypass/Jam valve and insert either the
2-pin Deutsch or 2-pin weatherpack connector tee (depending on the sprayer) on C10
between them. Connect the unused connectors on cable C10 together.

15
Figure 16: Bypass/Jam Valve Location
9. Connect the valve interface cable (C03) to connector S6 on (C10).
10. Connect the 2-pin connectors on the valve interface cable to the NORAC valve block, as
shown in Figure 17.
11. 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.

12. Fasten the 8-way coupler to the boom with cable ties. Connect P6 on C10 to the 8-way
coupler.
13. Connect the roll sensor to the 8-way coupler.
14. 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.
15. 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 the movement of the main
section, parallel lift, and FOLDING boom movement.

8Hydraulic Installation
Ensure all pressure has been bled from the system before disconnecting any lines
or fittings. Hydraulic pressure will exist on the wing tilt circuits unless the wings
are being supported by other means. The hydraulic installation may be performed
with the wings in transport position, resting on the ground or with the tilt cylinders
fully extended.
Component failure due to oil contamination is not covered under the NORAC
UC4.5 system warranty. It is recommended that a qualified technician perform the
hydraulic installation.
8.1 Valve Assembly
1. On a clean surface remove the plastic plugs from the block.
2. Insert the orifices (F05) into the “B” ports with the notch facing out.
3. Insert the orifices (F05) into the “A” ports with the notch facing in.
4. Install the 6MB-6MJ (F03) fittings into the “A” and “B” ports on the NORAC block. Tighten
to 18 ft-lbs (24 Nm).
