Example:
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 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 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 (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 6: Sensor Mounting Guidelines

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 NORAC ultrasonic sensor into the sensor bracket.
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 8: Mounting Roll Sensor to Bracket
Figure 9: Roll Sensor Orientation - Connector Facing Right Wing

12
6.2 Roll Sensor Mounting Guidelines: Center Pivot Booms
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 (non-
pivoting portion of the sprayer). For optimal performance, minimize the distance between
the roll sensors (A) and minimize the height from each roll sensor to the pivot point (B).
Figure 10: Roll Sensor Mounting on a Center Pivot 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.
5. The chassis roll sensor can also be mounted inverted to minimize the distance between the
roll sensors (Figure 11).

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 13.

7Electrical Installation
Figure 14: Cable Configurations: C03, C11, C12 and C13
1. Route C11 to the vicinity of the valve block at the rear of the sprayer. Note that the
R12/R6 connectors provide the hitch connection.
2. Connect the 6-pin shroud (S6) on C12 to the 6-pin tower (T6) on C11.
3. Connect the 3-pin shroud (S3) on C13 to the 3-pin tower (T3) on C11.
4. Route the free ends of C12 and C13 to the existing valve block. Insert all of the Deutsch
tees between the matching valve connections. The function is labeled on the branch wire
for each tee.
It is recommended to connect P2C and R2C (Bypass) on C13 to the existing
valve block even though it is not used.
5. Connect the 6-pin tower on C03 to the 6-pin shroud on C11. Connect the 2-pin
connectors on C03 to the NORAC valve block, as shown in Figure 15.
6. 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.

15
Figure 15: Valve Cable Connections
7. Fasten the 8-way coupler to the boom with cable ties. Connect P6 on C11 to the 8-way
coupler.
8. Connect both roll sensors to the 8-way coupler.
9. 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.
10. 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. Install the 6MB-6MJ (F04) fittings on the “P” and “T” ports on the NORAC block. Tighten
to 18 ft-lbs (24 Nm).
3. Insert the orifices (F06) into the “B” ports with the notch facing out.
4. Install the 6MB-6MJ (F04) fittings into the “B” ports on the NORAC block. Tighten to 18
ft-lbs (24 Nm).
1. Install the 6MBP plugs (F05) into the "A" ports on the NORAC block. Tighten to 18 ft-lbs
(24 Nm).
Figure 16: NORAC Valve Block Details

17
8.2 Valve Block Mounting
Ensure that no hydraulic components will interfere with any sprayer parts or be
pulled tight at any time.
1. A suitable mounting location for the valve block is illustrated in Figure 17.
2. Insert the threaded rod into the block and use a hex nut to hold the rod. The block holes
are 3/8” NC-1” deep. If bolts are used instead of the threaded rod, ensure the bolts thread
in at least 3/8”.
3. Use the remaining hardware to secure the block to the sprayer.
4. Cut off excess threaded rod, if necessary.
