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 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 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 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 UC5 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 controller 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.
Figure 8: Sensor Reading Off Boom

12
5.5 Main Lift Sensor Installation
Figure 9: Main Lift Bracket Assembly
1. 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 10.
2. Mount the ultrasonic sensor to the main lift bracket. Run the sensor cable down the center
of the main lift bracket tube.
Figure 10: 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 11: Mounting Roll Sensor to Bracket
Figure 12: Roll Sensor Orientation - Connector Facing Right Wing

6.2 Roll Sensor Mounting Guidelines: Center Pivot Booms
1. When mounting the roll sensors, mount one to the boom frame – lowest serial number,
one to boom carrier frame (intermediate frame - non-pivoting portion of the sprayer) and
one to the chassis (reference frame) – highest serial number. For optimal performance,
minimize the distance from the boom frame roll sensor to the pivot point (A) and minimize
the vertical distance between the intermediate frame roll sensor and the pivot point (B).
Figure 13: 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. All roll sensor cables should be pointing towards the right hand wing of the sprayer when
looking from the rear of the sprayer.
4. The intermediate frame roll sensor can also be mounted inverted to minimize the distance
between the roll sensors (Figure 14).

15
Figure 15: Boom Frame and Intermediate Frame Roll Sensor Mounting (Viewed from the rear of
sprayer)
5. The reference frame (chassis) roll sensor will be the roll sensor with the highest serial
number and should be mounted on the rear axle airbag base plate as shown in Figure 16.
Figure 16: Reference Frame Roll Sensor Mounting
6. Ensure all roll sensors are mounted adequately and that the cables provide enough slack to
allow sufficient boom roll.

7Module Installation
7.1 Control Module
1. Refer to Figure 1 and Figure 17.
2. Securely mount the control module (E01) inside the sprayer cab, using the included
brackets, screws or cable ties.
3. Connect the display terminal to the control module using the existing display cable. This
cable must be connected to the end of the control module with only one Deutsch
connector.
4. Connect the power cable (C30) to one of the two CANbus connectors on the control
module. Connect the other end of the power cable to a 12V, 15 amp source.
5. Route cable C01 from the other CANbus connector towards the rear of the sprayer.
6. At the spray system disconnect point there will be multiple connectors for the sprayer
electronics. At this point install the two way coupler (E12).
7. Connect cable C01 from the control module to the two way coupler.
8. Connect the second cable C01 to the two way coupler and route the cable to the rear of
the sprayer.

7.2 Valve Module
1. Install the valve module (E02) to the top of the NORAC valve block. Orient the 6-pin
Deutsch (CANbus) connectors towards the P and T ports with the label facing up.
Figure 18: Valve Module
2. Verify the valve coil connectors are oriented vertically (Figure 19).
Figure 19: Align Coils
3. Place the valve module between the valve coils. Slide a valve mounting bracket over the
connectors of the valve module and the valve coil connectors. This may require flexing the
plastic bracket slightly (Figure 20).
4. Ensure the bracket is pushed over the connectors far enough to allow the clips to engage
behind the valve connectors.
