4INSTALLATION 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

*Some sprayers may not have this function.
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 5 for the
RIGHT, MAIN and ROLL 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. Mount the Low Profile Sensor Mounting
Brackets (B20) onto the boom as show in
Figure 4 and Figure 5 with the mounting
base in front of the tube.
Figure 4: Low Profile Bracket Mounting
Figure 5: Low Profile Bracket Mounted on
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.
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+ system warranty
at the end of the UC4+ Sprayer Boom
Control Operator’s Manual (M01) for
implications.
2. Mount the NORAC UC4+ ultrasonic
sensors (E02) into the sensor brackets. The
sensors should be oriented forward (ahead)
of the boom.
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).
3. Sensor cables should run either through
hole in the back or through the side cut-out
and behind the bracket. Ensure the cable is
clear of moving parts and will not be
damaged during folding. Cable-tie the
connector in place. The cable must not hang
below the boom.

Rainflaps are only installed in the
wing sensor brackets.
4. Insert one side of the rainflap rod into the
pre-bent hinge tab on the sensor bracket.
(Figure 6)
Figure 6: Rainflap Rod in Pre-Bent Hinge
Tab
5. Align the other side of the rainflap rod with
the unbent hinge tab. (Figure 7)
Figure 7: Align Rainflap Rod
6. Bend the hinge tab inward over the rainflap
rod until the hinge tab fits securely in the
detent groove on the backside of the sensor
bracket. (Figure 8)
Figure 8: Bend Rainflap Hinge Tab
7. Ensure the rainflap actuates smoothly when
the bracket is turned upside down and
returns to the open position when the
sensor bracket is returned to its operating
position (sensor pointing downwards toward
the ground).
Figure 9: Bracket Mounting Example

General Mounting Rules for Low Profile
Brackets:
a) Minimize the distance between the bolts to
prevent bending the bracket and prevent the
bracket from loosening over time.
b) Ensure the bracket is mounted tight against
the bottom of the boom, minimizing the
distance between the boom structure and
the angled flange.
Figure 10: Bracket Mounting Guidelines
General Mounting Rules for UC4+
Ultrasonic Sensors:
a) In its lowest position, the sensor must be 9
inches (23 cm) or more from the ground.
b) Ensure that there are no obstructions within
a 12-inch diameter circle projected directly
below the center of the sensor.
c) The sensor should be approximately vertical
at normal operating heights.
Figure 11: Sensor Mounting Guidelines

4.4 MAIN LIFT SENSOR INSTALLATION
1. Mount the bracket onto the lowest
frame member on the center section of
the sprayer. (Figure 14 and Figure
15).
Figure 13: Main Lift Sensor Bracket
Mounting
The General Mounting Rules for
Low Profile Brackets and the
General Mounting Rules for
UC4+ Ultrasonic Sensors, from
the previous section, must be
followed.
2. Mount the sensor into the bracket.

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 16.
The roll sensors must be
mounted tightly to the brackets.
Figure 16: Mounting the Roll Sensor
to the Roll Sensor Mounting Bracket
When mounting the roll sensors, use the
following guidelines and refer to Figure 17.
a) The intermediate frame roll sensor
must have the lowest serial number and
the chassis roll sensor must have the
highest serial number.
b) The smaller the distance between Aand
Bin Figure 17, the better the
performance will be.
c) Ensure the roll sensors are sitting
relatively level when the sprayer chassis
and boom are level.
d) All roll sensors MUST be mounted with
the circular AMP connector facing
towards the Right-Hand Wing (when
looking from the rear of the sprayer).

4.5.1 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) with the
lowest serial number.
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.
Figure 18: Boom Frame Roll Sensor
Mounted to a Trapeze Link

16
4.5.2 Intermediate Frame Roll Sensor
Mounting
The intermediate frame roll
sensor has the temperature
probe on it.
1. It is often best to cable tie the
intermediate frame roll sensor in place.
When mounting the intermediate frame
roll sensor follow the guidelines and
refer to Figure 14.
The intermediate frame 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
(when looking from the rear of the
sprayer).
d) Make sure the temperature probe is
able to reach the side of the valve block.
Figure 19: Intermediate Roll Sensor
Mounting
2. Fasten the temperature probe to the
UC4+ valve block, using the supplied
3/8”x1/2” bolt as shown in Figure 17.
3. Cable-tie the temperature probe cable
and AMP (circular) connector securely
to a frame member.
Check that the roll sensors and
cables will not interfere with, or
come into contact with any parts
of the sprayer.
Figure 20: Temperature Probe
Attached to the UC4+ Valve Block

4.5.3 Reference Frame Roll Sensor
Mounting
The reference frame roll sensor
should be the highest serial
number.
1. The reference frame (chassis) roll sensor
mounts on the left side of the rear axle
below the main up/down coils (Figure
18). The AMP (circular) connector
MUST exit towards the right hand
wing.
2. Ensure the sensor is mounted adequately
and that the cable provides enough slack.
