4 INSTALLATION PROCEDURE
4.1 DETERMINING THE STYLE OF
INSTALLATION
This install may require additional
electrical/hydraulic components.
Do NOT proceed with install until
all parts are available.
In general, there are two styles of installation
that can be done with the NORAC UC4+ Spray
Height Control system: Electrically Teed
Installation and Hydraulically Teed Installation.
4.1.1 Electrically Teed Installation
Electrically Teed Installation is the preferred
style of installation. However, this style can
be done only if the sprayer valve block has
individual electrical wiring to control each
boom function (e.g. left up, left down, right
up, right down, main up, and main down).
Figure 3 and Figure 4 show the
Electrically Teed installation in its
general installation configuration.
Figure 3 – Electrical Wiring Applicable for Electrically Teed Installation

7
Figure 4 – Hydraulic Components: Electrically Teed Installations

8
4.1.2 Hydraulically Teed Installation
Hydraulically Teed Installation must be done
if the sprayer valve block does NOT have
individual electrical wiring to control each
boom function. For example, your sprayer
may have signal lines to select a boom (left,
right and main) and separate electrical signals
for the direction (up and down).
For Hydraulically Teed Installation,
MANUAL mode of the UC4+ Control
System does not operate the same as with
Electrically Teed Installation. Electrically
Teed Installation will allow the operator to
trigger individual boom movements into
MANUAL mode while maintaining AUTO
mode for the other boom movements (e.g.
left boom can be in MANUAL mode while
right boom is still in AUTO mode).
Hydraulically Teed Installation does not
support this function. If the operator
triggers any boom movement, the whole
NORAC system will convert to MANUAL
mode.
Hydraulically Teed Installation may
also be done if the operator wants
the existing sprayer valves, instead
of the NORAC valves, to operate
the booms when the NORAC
system is in MANUAL mode.
Figure 5 and Figure 6 show the
Hydraulically Teed Installation in its
general installation configuration.
Figure 5 – Typical Electrical Wiring for which Hydraulically Teed Installation is Required

4.2 WING SENSOR INSTALLATION
1. Assemble the Breakaway Sensor Mounting
Brackets (B11) as show in Figure 7 and
Figure 8.
Figure 7 – Breakaway Sensor Bracket
Exploded View
Figure 8 – Breakaway Sensor Mounting
Bracket Assembly
To assemble the breakaway sensor bracket:
a) Assemble the bolt and nut into the
collar.
b) Grease the bottom edge of the collar
and the angled tube of the base.
c) Place the collar onto the angled tube of
the mounting base.
d) Install the spring between the collar and
the upper ring of the base.
e) Insert tube through assembly and tighten
the collar
2. Mount the sensor bracket onto the boom.
If possible, mount the sensor
brackets while the booms are in
their folded position to ensure that
they will not interfere with anything
when the boom is folded for
transport.
3. The sensor mounting brackets can be
installed with the mounting base behind
(Figure 11) or in front of the tube (Figure
9).
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.
Please refer to the UC4+ Spray Height
Control system warranty at the end of the
UC4+ Spray Height Control
Operator’s Manual (M01) for
implications.
4. Mount the NORAC UC4+ ultrasonic sensor
(E02) into the sensor brackets. The sensors
should be oriented forward (ahead) of the
boom (see Figure 9 and Figure 11).

11
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 12).
5. Sensor cables should run through the
mounting bracket tube and then behind the
member the bracket is mounted onto.
Cable-tie the connector in place. The cable
must not be allowed to hang below the
boom (Figure 9).
Figure 9 – Another Acceptable Mounting
Avoid mounting sensors in
locations where they may read
from parts of the boom as shown in
Figure 10.
Figure 10 – Poor Mounting
(Sensor reading off Boom)
General mounting rules for UC4+
ultrasonic wing 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.

4.3 MAIN LIFT SENSOR INSTALLATION
1. Assemble the main lift sensor bracket (B11)
as shown in Figure 13.
Figure 13 – 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 14 and Figure
15).
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.

4.4 ROLL SENSOR INSTALLATION
Mount the roll sensors to the included roll
sensor brackets using the machine screws
and nylon lock nuts, as illustrated in Figure
16.
The roll sensors must be mounted
tightly to the brackets.
If your sprayer is a trapeze style
pivoting boom (the boom hangs
from two link arms) then follow
Section 4.4.1 to install the roll
sensors.
If your sprayer is a center pin
pivoting boom (the boom pivots on
a pin in the center of the boom)
then follow Section 4.4.2 to install
the roll sensors.
Sometimes it best to mount the
roll sensors in an inverted
orientation (upside down). For this
type of mounting refer to Section
4.4.3.
Figure 16 – Mounting the Roll Sensor to
the Roll Sensor Mounting Bracket

15
4.4.1 Trapeze Style Roll Sensor Installation
This section is only for trapeze style
booms (booms that hang from link
arms. If your sprayer has a center
pivot boom proceed to Section
4.4.2.
When mounting the roll sensors, use the
following guidelines and refer to Figure 17.
a) The smaller the distance between Aand
Bin Figure 16, the better the
performance will be.
b) Ensure the roll sensors are sitting
relatively level when the sprayer chassis
and booms 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).

4.4.1.1 Boom Frame Roll Sensor Mounting
1. Use the supplied hardware to mount the
boom frame roll sensor (E04) as shown in
Figure 18.
When mounting the boom frame roll sensor
follow these guidelines:
a) To prevent bending the bracket, ensure
bolts are placed as close together as
possible (minimize Cin Figure 18).
b) Be sure to use the roll sensor without
the temperature probe (E04).
c) When the boom is centered (not rolled
over) the roll sensor should be level
with respect to the sprayer chassis.
d) It is best to mount the roll sensor to
the left hand trapeze link (when looking
from the rear of the sprayer).
e) The roll sensor AMP (circular)
connector MUST exit towards the
right hand wing (when looking from
the rear of the sprayer).
2. Cable-tie the sensor connector to the frame
with enough slack to allow the link to rotate.
Make sure the bracket does not
collide with any parts of the sprayer
when the boom rotates. Also
ensure there is enough slack to
allow the roll sensor to rotate.

4.4.1.2 Chassis Roll Sensor Mounting
1. It is often best to cable tie the chassis roll
sensor in place. When mounting the chassis
roll sensor follow the guidelines and refer to
Figure 19.
The chassis roll sensor must be
mounted on a portion of the
sprayer that does not pivot and is
as close to the boom frame roll
sensor as possible (Figure 17).
a) Make sure you are using the roll sensor
with the temperature probe (E03).
b) Ensure the roll sensor is level with
respect to the chassis.
c) The AMP (circular) connector MUST
exit towards the right hand wing.
d) Make sure the temperature probe is
able to reach the side of the valve block.
Figure 19 – Chassis Roll Sensor Mounting
2. Refer to Section 1.1.1 on page 20 for
mounting the temperature probe.
