4 INSTALLATION PROCEDURE
4.1 SENSOR INSTALLATION
It is advised to avoid mounting the
sensor bracket to a breakaway
portion of the boom because a
breakaway action can cause the
UC4+ system to force a boom close
to the ground.
When installing the UC4+ sensors
(E02), start with the smallest serial
number on the left hand side
proceeding to the largest serial
number on the right hand side
(Figure 6).
Avoid mounting sensors in
locations where they may read
from parts of the boom as shown
in Figure 4.
The main lift sensor must not be
located behind the sprayer’s
wheel.
Figure 4 - Poor Mounting
(Sensor reading off boom)
General mounting rules for UC4+
ultrasonic sensors:
a) In its lowest position, the sensor mouth
must be 9 inches or more from the
ground.
b) The bottom of the sensor must be at least
9 inches in front of the spray nozzles.
c) The bottom of the sensor must be at least
9 inches above the spray nozzles.
d) Ensure that there are no obstructions
within a 12-inch diameter circle
projected directly below the center of the
sensor.
e) The sensor should be approximately
vertical at normal operating heights.

4.2 ROLL SENSOR INSTALLATION
Mount the roll sensors to the included roll
sensor brackets using the machine screws
and nylon lock nuts. (Figure 7)
The roll sensors must be mounted
tightly to the brackets.
Figure 7 – Mounting the Roll Sensor to the
Roll Sensor Mounting Bracket
When mounting the roll sensors use the
following guidelines and refer to Figure 8.
a) The smaller the distance between Aand
Bin Figure 8, the better the
performance will be.
Distance A can not be more than 12”.
b) The roll sensors must not be mounted
below the pivot point.
c) Ensure the roll sensors are sitting
relatively level when the sprayer chassis
and boom are level.
d) Both roll sensors must be mounted with
the circular AMP connector facing
towards the Right-Hand Wing (when
looking from the rear of the sprayer).

a) Make sure you are using the roll
sensor that does NOT have a
temperature probe (only one cable)
(E02).
b) The boom roll sensor must be
mounted to the rotating part of the
boom suspension.
c) Use cable-ties to secure the bracket
to a square edge feature (square
tube).
d) Ensure the AMP (circular)
connector exits towards the Right
Hand Wing (when looking from the
rear of the sprayer).
e) Securely cable-tie the connector to
the frame.
4.2.2 Chassis Roll Sensor Mounting
The chassis roll sensor must be mounted
to a non-rotating part of the boom. To
mount the chassis roll sensor, follow the
following guidelines and refer to Figure
11.
a) Make sure you are mounting the roll
sensor that does have a temperature
probe (2 cables) (E03).
b) Mount the chassis roll sensor (E03)
to a non-rotating part of the boom.
c) Cable-tie the bracket to a square
edge feature (square tube).
d) The AMP (circular) connector
MUST exit towards the Right Hand
Wing (when looking from the rear).
e) Securely cable-tie the connector to
the frame.

4.2.3 Inverted Roll Sensor Mounting
If desired, the Roll sensor may be
mounted inverted, so long as the
connector exits towards the right-hand
boom. Inverted mounting may be used
to optimize the mounting criteria
explained in Section 4.2.
Figure 12 – Inverted Roll Sensor Mounting may be Applicable in Order for Optimal
Performance
4.2.4 Temperature probe
Fasten the temperature probe (E03) to the
UC4 valve block using the included
3/8x1/2” bolt as illustrated in Figure 13.

4.3 HYDRAULIC INSTALLATION
If your valve block appears different than
shown in the images, see Appendix A for
more details.
4.3.1 Valve Mounting
1. On a clean surface remove all plastic
plugs from the NORAC hydraulic Valve
(V01) (Figure 14).
2. Install the orifices (F06) into the “B”
ports with the notch facing outward as
shown in Figure 15.
Figure 14 – NORAC Valve Block
3. Install the 6MB-6MJ fittings (F04) into
the “B” ports and tighten to 18 ft-lbs.
4. Install the 6MB-plugs (F05) into the “A”
ports and tighten to 18 ft-lbs.
Figure 15 – Valve Block Assembly
5. Mount the NORAC valve (V01) on the
sprayer. The bolts should thread into the
valve block at least 3/8”. The valve
mounting holes are drilled and tapped
3/8 NC-1" deep. The rule of thumb for
bolt length is 1-1/2" longer than the tube
size.
4.3.2 Hydraulic Plumbing
1. After the NORAC valves are mounted,
the hydraulic hoses and fittings can be
plumbed. The plumbing for the
hydraulic circuit is shown schematically
in Figure 3.
2. The “raise” lines must be connected to
the “B” ports of the NORAC valve
block. Insert the “T” fittings (F02) to the
sprayer block and connect the “raise”
lines. Connect the hoses to the open
ports on F02 and the “B” ports of the
NORAC block.
The “T” fittings are inserted into
the hydraulic circuit to allow the
NORAC valve block to control the
cylinders in parallel with the
existing system.

3. Tee in the pressure (“P”) and tank (“T”)
lines for the NORAC block in to the
existing lines from the valve block,
using the “T” fitting (F03).
You must ensure there are no
other orifices present in the circuit
between the NORAC valve block
and the boom cylinders.

4.4 ELECTRICAL INSTALLATION
Figure 16 – Cable Configurations: Rear of the sprayer
1. Route C11 to the rear of the sprayer, in
the vicinity of the valve block. Note that
the 16-pin AMP plug (P16) provides the
hitch connection.
2. Connect the 3-pin Shroud (S3) on the
wing interface cable (C12) to the mating
3-pin Tower (T3) on C11.
3. Connect the 6-pin Shroud (S6) on the
main interface cable (C13) to the mating
6-pin Tower (T6A) on C11.
4. Route the free ends of C12 and C13 to
the existing valve block and insert all of
the Deutsch tees between the matching
valve connections. For each tee, the
function is labeled on the branch wire.
It is recommended to connect P2C
and R2C (Bypass) on C12 to the
existing valve block even though it
is not used.
5. Connect the 6-pin Tower on the valve
cable (C03) to the mating 6-pin Shroud
(S6A) on C11
6. Install the square DIN connectors from
C03 onto each NORAC valve as shown
in Figure 17. The connectors on the
valve cable are marked RIGHT UP,
LEFT UP, RIGHT PORT (“right
down”), and LEFT PORT (“left
down”). Fasten with the included rubber
seals and screws. Ensure that the cables
are oriented as shown, with the cable
labels RIGHT PORT and LEFT
PORT on the SAME side as the
hydraulic hoses (the “port-side” of the
block).

16
Figure 17 – Valve Cable Connections
7. Connect the CAN Node cable (C02B) to
the 4-pin AMP plug (P4) on C11.
8. Route the CAN Node cable (C02B) to
the roll sensors. Follow existing cables
and/or hydraulic lines.
9. Connect the sensor branch cable (C02)
to the 4-pin AMP plug on C02B .
10. Route the sensor branch cable (C02) to
the wing and main sensors. Follow
existing cables and/or hydraulic lines
along the boom.
11. Cable-tie the installed cables every 12
inches.
IMPORTANT:
Provide enough slack in all cables to
account for the movement of the main
section, parallel lift, and FOLDING boom
movement.

4.5 COMPLETING THE FACTORY INSTALL
1. Test the functionality of the original
manufacturer’s boom controls. The
NORAC Control Panel (Item E01) does
not need to be powered up for the
original switches to function. Unfold the
booms and raise/lower each boom and
main section. Confirm that the
cabling/hoses are agreeable to the entire
range of motion. If one or more of these
functions do not work, review the
hydraulic and electrical portions of this
manual to check for proper installation.
2. Unfold the booms and level to 90 cm (or
35 inch) nozzle height. At this point
ensure the UC4 sensors are reading from
an adequate and uniform target, such as
gravel or dirt, or concrete.
3. By using the “Quick Install” feature of
the UC4+ panel, the system may be
configured in preparation for the End-
User. However, a hydraulic “ReTune”
procedure will be required for optimal
performance. This is required to tune
the UC4+ hydraulic parameters to those
of the End-User tractor hydraulic
system.
4. To perform the “Quick Install”
procedure, select the FT1 sprayer type.
However, rather than toggling “YES” to
select the FT1 type, hold the toggle
switch towards “YES” (for several
seconds) until the word “SENSOR”
appears on the UC4+ controller screen.
5. The UC4+ control panel will then
prompt the installer to “EXIT CAB
AND PUSH BOOM TIP DOWN TO
GROUND”. When exiting the cab and
approaching the boom, avoid walking
near the sensors as this may result in
measurement error.
6. At this point the UC4 panel should
display the Main Operating Screen:
↓M 90 M (example)
7. This indicates the system is ready for the
second stage of installation. This will be
carried by the end user (for the reasons
as described previously in Step 3).
