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.

4Existing System Check
1. Before beginning the install, ensure all hydraulic boom functions are operating properly on
the sprayer.
All Fold Functions
Main Lift Function
Wing Tilt Functions
Slant Function
2. Inspect slide pads and wear surfaces for excessive wear. Replace or adjust if necessary.
3. Ensure the boom guide-rods are set to the “tapered” position (factory setting).
4. Set boom suspension to be critically damped (Figure 5). Adjust the boom damper
accordingly.
a. Unlock the pendulum, and push boom tip down approximately 75 cm (30 inches).
b. Hold the boom steady for a moment, and release.
c. Ensure the boom returns to its relaxed state as quickly as possible, with little to no
overshoot.
Figure 5: Boom Push Test- Critically Damped
5. Unfold the sprayer over a flat, unobstructed area (i.e. no power lines…etc.).
6. Ensure all boom-fold operations are functional (place a check mark in boxes below).
7. Bring engine to field-operational RPM and record.

9
8. Record the time (seconds) it takes for a full stroke for all boom functions. To ensure
repeatable measurements, take the average of 3 trials.
9. Not all sprayers will have the functions listed below in Figure 6.
Ensure the boom has sufficient travel so it does not contact the ground during
these tests.

5Ultrasonic Sensor Installation
5.1 Bracket Assembly
Assemble the breakaway sensor bracket as illustrated in Figure 7, following the instructions
below.
Figure 7: 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.

11
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 8: 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 9: Sensor Mounting Guidelines

13
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. Tighten screws to 10 in-lbs (1.1 Nm).
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 12: Roll Sensor Orientation - Connector Facing Right Wing

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 13: 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 14.
