NOTE: Fitting F04 is not used for this install.
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.

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.

9
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 (M06) 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

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. Mount the NORAC ultrasonic sensor into the sensor bracket and run the sensor cable
through the sensor tube.
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
6.1 Bracket Assembly
1. Securely mount the roll sensors to the included roll sensor brackets using the #6 machine
screws.
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 9: Mounting Roll Sensor to Bracket
Figure 10: Roll Sensor Orientation - Connector Facing Right Wing

6.2 Roll Sensor Mounting Guidelines: Trapeze-Suspended Booms
1. When mounting the roll sensors, mount a roll sensor without the temperature probe
(E04) with the lowest serial number on the trapeze link (boom frame), a roll sensor
without the temperature probe (E04) with the highest serial number on the chassis
(reference frame), and the roll sensor with the temperature probe (E03) on the boom
carrier frame (intermediate frame). For optimal performance, minimize the distance from
the boom frame roll sensor to the pivot point (A) and minimize the vertical distance
between the chassis roll sensor and the pivot point (B).

sprayer)

Figure 13: Reference Frame Roll Sensor Mounting Location
2. Ensure the roll sensors are relatively level when the sprayer boom and chassis are level.
3. All roll sensor cables should be pointing towards the right hand wing of the sprayer when
looking from the rear of the sprayer.
4. Ensure all 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 can be found 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 the other end of
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.

16
Figure 16: Cable Configurations: C03, C11 and C12
6. Run cable C11 to the rear of the sprayer, in the vicinity of the valve block.
7. Connect the 6-pin shroud (S6) on C12 to T6 on C11.
8. Route the free end of C12 to the Miller valve block and insert the 2-pin tees between the
matching valve connections. For each tee, the function (e.g. “Main Up”) is labeled on the
branch wire.
9. Unplug the connectors on the existing valves. There are 4 connectors to unplug (as labeled
on the valve bank): LEFT UP, LEFT DOWN, RIGHT UP and RIGHT DOWN. Plug in the 2-
pin tower of C12 to the matching existing valve connections. For each connector, the
function (e.g. “LEFT UP”, etc.) is labeled on the branch wire.
10. Connect the valve interface cable (C03) to connector S6 on the valve extension cable
(C11).
11. Connect the 2-pin connectors on the valve interface cable to the NORAC valve block, as
shown in Figure 17.
12. 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 17: Valve Cable Connections

13. Fasten the 8-way coupler (E11) to the boom with cable ties.
14. Connect P6 on C11, the chassis roll sensor (reference frame) and cable C07 to the 3-way
coupler (E10). Connect the free end of C07 to the 8-way coupler (E11).
15. Connect the boom frame roll sensor and intermediate frame roll sensor to the 8-way
coupler.
16. 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.
17. 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.
