4 INSTALLATION PROCEDURE
4.1 SENSOR INSTALLATION
Mounting the sensor bracket to
the break-away section of the
boom may cause the boom to
drop suddenly as a break-away
occurs. This will occur on break-
away sections which lift as they
break away.
For optimal boom tip protection,
it is recommended that the
sensor be mounted within
approximately two feet (60cm) of
the boom tip.
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.
The smaller the distance between Aand B
in Figure 8, the better the performance will
be.
Distance A cannot be more than
12”.
a) The roll sensors must not be mounted
below the pivot point.
b) Ensure the roll sensors are sitting
relatively level when the sprayer chassis
and boom are level.
c) 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).

4.2.1 Boom Roll Sensor Mounting
The boom roll sensor (E02) must be
mounted to the rotating part of the
boom. Follow these guidelines and
refer to Figure 11 to mount the
sensor.
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 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.
Figure 13 – UC4+ Valve Block with
Temperature Probe Installed

4.3 HYDRAULIC INSTALLATION
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.

14
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 (C13) to the
mating 3-pin Tower (T3) on C11.
3. Connect the 6-pin Shroud (S6) on the
main interface cable (C12) to the
mating 6-pin Tower (T6A) on C11.
4. Route the free ends of C13 and C12 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 C13
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. 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.
Figure 17 – Valve Cable Connections

16
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).
