4 INSTALLATION PROCEDURE
4.1 EXISTING SYSTEM CHECK
It is necessary to check the existing
system’s functionality before installing the
UC4+ Spray Height Control system.
1. Drive your sprayer onto a flat piece of
land, with unobstructed boom movement
(e.g. no power lines).
2. Test that all boom functions operate
correctly. As you test each function check
it off in Table 3.
It is necessary to test the boom
functions in all directions
Table 3 – Hydraulic System Function

MAIN
RIGHT
4.2 BOOM SPEED TEST
IMPORTANT:
Raise/lower all boom sections several
times to warm up the hydraulic
system. Grease all moving parts for
consistent results.
1. Lower each boom and main section as
close to the ground as possible.
2. Set your sprayer at field working RPM
on the throttle and mark this value in
Table 4.
You will need a stopwatch or a
watch that displays “seconds”
for the next step.
3. Raise the LEFT boom from its extreme
LOW position to the very TOP of its
travel. Record the time this takes in
Table 4,“Trial #1” for “Left UP”.
4. Lower the LEFT boom from its extreme
HIGH position to the BOTTOM of its
travel. Record this time in Table 4,
Trial #1 for “Left DOWN”.
Be careful when lowering the
booms so they don’t hit the
ground.
5. Similarly, record two more time trials
(Trial #2 & #3) for the LEFT boom and
record in Table 4.
6. Repeat Steps 1 through 5for the
RIGHT, and MAIN functions.
Your sprayer may not have a
roll feature.
7. Average the three trials recorded for
each boom movement and record this
calculation in the “Average Time” slot in
Table 4.
8. These “Average Times” now represent
how quickly your system can react to
manual control. In Section 4.8, this
procedure is repeated with the UC4+
Spray Height Control system installed
for comparison and troubleshooting
purposes.

4.3 WING SENSOR INSTALLATION
1. Assemble the Breakaway Sensor
Mounting Brackets (B11) as show in
Figure 4.
Figure 4 – Breakaway Sensor Bracket
Exploded View
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.
3. Optional spacers and plate may be
needed on some booms to prevent
collision between the bracket and boom
during folding.
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.
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.
Figure 5 - Acceptable Mounting
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 (Figure 5 and
Figure 7).
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 8).
FRONT

11
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 6).
Figure 6 - Sensor Cable Routing
Avoid mounting sensors in
locations where they may read
from parts of the 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.

4.4 MAIN LIFT SENSOR INSTALLATION
1. Mount the main lift sensor with the
bracket provided (B11). The sensor
should point behind the boom, but be
ahead of the spray nozzles.
Make sure the sensor has
clearance when the main
section is raised and lowered.
2. Aim the sensor perpendicular to the
ground. Tighten all the sensor bracket
bolts.
General mounting rules for ultrasonic
main lift sensor:
a) Mount the sensor at the midpoint of the
main lift section.
b) The sensor must have a 12-inch
diameter clear view of the ground
without any obstructions.
c) Ensure that there will be no contact
between the sensor and the booms
when folding and unfolding, or raising
and lowering.
d) The bottom of the sensor must be at
least 9 inches in front of the spray
nozzles.
e) The bottom of the sensor must be at
least 9 inches above the spray nozzles.

4.5 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 9.
The roll sensors must be
mounted tightly to the
brackets.
Figure 9 – Mounting the Roll Sensor
to the Roll Sensor Mounting Bracket
When mounting the roll sensors use the
following guidelines and refer to Figure
10.
a) Ensure the roll sensors are sitting
relatively level when the sprayer
chassis and boom are level.
b) 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).
