Example:
* Orifice F08 is not required when installing on a John Deere 4930.
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.

3Ultrasonic Sensor Installation
3.1 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 2: Sensor Mounting Guidelines

6
3.2 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 3: 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.

3.3 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 5.
Figure 4: Bracket Mounting Example
3. Mount the ultrasonic sensor to the main lift bracket. Run the sensor cable through hole
and behind the bracket.
Figure 5: 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.

4Hydraulic Installation
Ensure all pressure has been bled from the system before disconnecting any lines
or fittings. Hydraulic pressure will exist on the main lift circuit unless the main lift
is all the way down.
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.
4.1 Expansion Block Assembly
1. Use Figure 1 as a reference for installing the hydraulics.
2. Loosen the existing 2-station valve block so that it can be moved and/or twisted for the
installation of the expansion block.
3. Remove the four 4MBP plugs from the 2 station valve block.
4. Coat the four o-rings in hydraulic oil and install them into the expansion block. Ensure the
o-rings are seated properly.
5. Attach the expansion block to the 2 station block using the included spring washers and
bolts.
6. Tighten the bolts to 31 ft-lbs.

4.2 Hydraulic Plumbing
1. Install the orifice (F08) and the 6MB 6MOR fitting (F05) into the “B” port of the expansion
block.
The orifice is not required for John Deere 4930 sprayers.
2. Install the 6MBP plug (F09) into the “A” port of the expansion block.
3. If the valve block is not already installed on the sprayer, install it as outlined in the UC4.5
Spray Height Control installation manual.
4. Attach hose H01 to the “B” port on the expansion block. Route the free end of the hose
to the John Deere valve block.
5. Tee in H01 to the existing main lift line on the John Deere valve block, using the tee fitting
(F03).

Figure 8: Main Lift Tee Fitting Installed
Ensure no hydraulic components will interfere with any sprayer parts or be pulled
tight at any time.

5Electrical Installation
Figure 9: Cable Connections
Only parts shown in black are included in this kit.
1. Connect the 6-pin shroud (S6) on C17 to T6 on C11 (previously installed).
2. Connect the 3-pin tower (T3) on C17 to S3 on C11.
Two connectors on C17 will remain disconnected. These are used when
installing other UC4.5 options.
3. Install the two 2-pin connectors on the end of cable C17 to the expansion block.
The connector marked “Main Up” goes on the port side of the block. The
port side of the block is the side with the hose connections.
4. Connect the main lift sensor to the 8-way coupler using cable C07 and a 2-way coupler
(E12). Cable C07 and item E12 may not be needed if the 8-way coupler is mounted close
enough to the main lift sensor.

6Software Setup
1. Start up the sprayer and test the sprayer’s functionality. The control panel does not need
to be powered on for the original switches to function.
Confirm that the cabling and hoses are agreeable to the entire range of motion.
2. If any functions do not work, review the hydraulic and electrical portions of this manual to
check for proper installation.
3. Turn on the power for the control panel using the switch on the side of the chassis.
4. Refer to the UC4.5 Spray Height Control Operator’s Manual to run an automatic install
with the JD9 type selected.
