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 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.
Figure 5: Sensor Serial Number Arrangement

5.2 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 6: Sensor Mounting Guidelines

10
5.3 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 7: 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.

11
5.4 Wing Sensor Installation
1. The wing sensor mounting brackets (B20) are the two brackets with the shorter mounting
flange.
2. The sensor bracket should be oriented forward (ahead of the boom).
3. 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.
4. 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.
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.

5.5 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 9)
Figure 9: Rainflap Rod in Pre-Bent Hinge Tab
2. Align the other side of the rainflap rod with the unbent hinge tab. (Figure 10)
Figure 10: 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 11)
Figure 11: 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).

13
5.6 Main Lift Sensor Installation
1. The main lift mounting bracket (B21) is the bracket with the longer mounting flange.
2. There are a variety of ways to mount the main lift bracket on most sprayers. The bracket
should position the sensor approximately in the center of the sprayer, forward of the
boom. An example of this mounting is illustrated in Figure 13.
Figure 12: Bracket Mounting Example
3. Mount the ultrasonic sensor to the main lift bracket. Run the sensor cable through hole
and behind the bracket.
Figure 13: Example Mounting of the Main Lift Bracket
Avoid mounting the main lift sensor over or near a wheel-track. Measurements
from the wheel-track do not provide an accurate crop height and will cause
measurement and control error.
Ensure the bracket does not collide with any other part of the sprayer throughout
the full range of main lift motion.

6Roll Sensor Installation
6.1 Bracket Assembly
1. Securely mount the roll sensors to the included roll sensor brackets using the #6 machine
screw and nylon lock-nuts.
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 14: Mounting Roll Sensor to Bracket
Figure 15: Roll Sensor Orientation - Connector Facing Right Wing

15
6.2 Roll Sensor Mounting Guidelines: Trapeze-Suspended Booms
1. When mounting the roll sensors, mount the roll sensor without the temperature probe on
the trapeze link (boom frame) and the roll sensor with the temperature probe on the
trapeze support (chassis). 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).
Figure 16: Roll Sensor Mounting on a Trapeze Suspended Boom
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 17.

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 19: 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 3-pin AMP
connector C30 to an auxiliary power connection in the sprayer cab. If an appropriate
connector cannot be found, it may be necessary to cut off the connector and splice into the
existing wiring.
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.
