4 INSTALLATION PROCEDURE
4.1 SENSOR INSTALLATION
To correctly mount the sensor brackets,
the bracket mounting adapter will most
likely be used. A completely assembled
sensor bracket, with mounting adapter is
shown in Figure 4.
Figure 4 - Sensor mounting bracket
and adapter
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 10).
Avoid mounting sensors in
locations where they may read
from parts of the boom as
shown in Figure 5.
Figure 5 - 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 MAIN LIFT SENSOR INSTALLATION
1. Assemble the main lift sensor
bracket (B11) as shown in Figure 7.
Figure 7 – Main Lift Sensor Bracket
2. The bracket can then be mounted to
the lowest frame member on the
center section of the sprayer. The
bracket should be mounted so the
sensor mounting collar is in
approximately the center of the
sprayer and ahead of the boom
(Figure 8 and Figure 9).
The sensor mounting collar
must not be behind the
sprayer’s wheel.
The General Mounting Rules
for UC4+ Ultrasonic Sensors,
from the previous section, must
be followed.

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 11).
2. Install the orifices (F06) into the “B”
ports with the notch facing
outward as shown in Figure 12.
Figure 11 – 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 12 – Valve Block Assembly
5. Mount the NORAC valve (V01) on
the sprayer using the valve mounting
bracket (B10).
6. As shown in Figure 13, screw short
side of the threaded rods into the
bottom of the valve block at least
3/8". The valve mounting holes are
drilled and tapped to 3/8 NC-1"
deep.
Figure 13 – Valve Mounting Location
7. Tighten the Hex nuts to hold the rods
in the valve block.
8. Put the mounting bracket on the
other side of the tube and tighten in
place with the spring washers and the
Hex nuts.
9. Cut the excess rods off, if necessary.
If using bolts, 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. When plumbing, the “raise” lines
must be connected to the “B” ports
of the NORAC valve block.
There must be a 1/32” orifice
inline with each of the
accumulators, as shown in the
plumbing schematic (Figure 3).
You must ensure no hydraulic
components will interfere with
any sprayer parts or be pulled
tight at any time.

4.4 ELECTRICAL INSTALLATION
Figure 14 – 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
provides the hitch connection.
2. Connect the 3-pin shroud on the
generic interface cable (C13) to the
mating 3-pin tower on C11.
3. Connect the 6-pin shroud on the
generic interface cable (C13) to the
mating 6-pin tower on C11.
4. Route the free ends (ring terminals)
of C13 to the existing valve block
and connect them to the appropriate
locations. Each ring terminal is
labeled with its function.
5. Connect the 6-pin Tower on the
valve cable (C03) to the mating 6-
pin Shroud (S6A) on C11

13
6. Install the square DIN connectors
from C03 onto each NORAC valve
as shown in Figure 15. 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).
Figure 15 – Valve Cable Connections
7. Connect the sensor branch cable
(C02) to the 4-pin AMP plug on
C11.
8. Route the sensor branch cable (C02)
to the wing and main sensors. Follow
existing cables and/or hydraulic lines
along the boom.
9. 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 RH1 sprayer
type. However, rather than toggling
“YES” to select the RH1 type, hold
the toggle switch towards “YES”
(for several seconds) until the word
“SENSOR” appears on the UC4+
controller screen.
5. After some messages, the UC4 panel
should display the Main Operating
Screen:
↓M 90 M (example)
6. 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).

5 END USER INSTALLATION
1. Install the UC4+ Control Panel
(E01) in the cab of the sprayer.
Mount the panel where it will be
clearly visible and within easy reach
of the operator.
A good spot to mount the UC4+
control panel is on the right hand
side of the cab to the Roll Over
Protection Bar. Four pilot holes for
the screws provided need to be
drilled to facilitate the control panel
mounting.
Another option is to purchase an
adapter for the flexible panel mount
that has a 3/8" NC threaded stud on
the end to bolt through an existing
mount. You can find these at your
local outdoor store as a RAM mount
part number RAM-B-236. (See
http://www.ram-mount.com/)

Figure 17 – Cable Configurations: C10, C10A and C11
2. Connect the power cable (C10) to
the UC4+ Control Panel in the
sprayer cab. Ensure that both plugs
(P16A and P4) are connected to the
panel (Figure 17).
Ensure that the UC4+ Control
Panel is OFF for the remaining
installation (Bottom of switch
pressed IN). Use caution when
handling the 12V power line of
the sprayer wiring.
3. Connect the 3-pin AMP connector
(P03) on C10 to the pull type power
cable (C10A). Cable C10A then
connects to an auxiliary power
connection inside the sprayer cab. If
an appropriate connector(s) cannot
be found it may be necessary to cut
off the connector(s) and splice into
the existing wiring. Refer to Section
6 for wiring information.
4. Route the free end (R16) of C10 to
the exterior of the cab, to the vicinity
of the tractor hitch. This connector
will provide your hitch connection.
Route the cable accordingly and
connect it to P16 on the sprayer.
The procedure for the installation of
the UC4+ system is now complete.
5. For optimal performance of the
UC4+ Spray Height Control system,
there should be very little play at the
hitch clevis. The addition of
polymer washers can help tighten up
this connection (Figure 18).
Figure 18 – Hitch Point
6. Power on the UC4+ panel, if “RH1”
shows up as your sprayer type, you
can start the ReTune process as per
the UC4+ Operator Manual. This
will tune the UC4+ hydraulic
parameters to your tractor hydraulic
system.
7. If no type is selected yet, start the
Install as per the UC4+ Operator
Manual.
