5. Mount the NORAC UC4+ ultrasonic
sensor (E02) into the sensor brackets.
The sensors should be oriented forward
(ahead) of the boom (see Figure 7 and
Figure 9).
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).
6. 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 7).
Figure 7 – Another Acceptable Mounting
Avoid mounting sensors in
locations where they may read
from parts of the boom as shown
in Figure 8.
Figure 8 – 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.

4.3 R OLL S ENSOR I NSTALLATION
When mounting the roll sensors,
be sure they can not contact any
parts of the boom or frame.
Mount the roll sensors to the included
roll sensor brackets using the machine
screws and nylon lock nuts, as illustrated
in Figure 14.
The roll sensors must be mounted
tightly to the brackets.
Figure 14 – Mounting the Roll Sensor to
the Roll Sensor Mounting Bracket
When mounting the roll sensors, use the
following guidelines and refer to Figure 15.
a) The smaller the distance between A
and Bin Figure 15, the better the
performance will be.
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).

4.3.1 Boom Frame Roll Sensor
Mounting
1. Use the supplied hardware to mount the
boom frame roll sensor (E04) as shown
in Figure 16.
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 16).
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 had wing (when looking from
the rear of the sprayer).
Figure 16 – Boom Frame Roll Sensor
Mounted to a Trapeze Link
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.

14
4.3.2 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 17.
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 15).
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 17 – Chassis 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 18.
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.

4.4.3 Hydraulic Plumbing
WARNING!
From this point in the installation the
booms will be inoperative until the
electronics are fully installed.
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. Connect the NORAC supplied hoses
(H01) to the Pressure (P) and Tank (T)
ports on the NORAC valve block (V01).
3. Remove the plugs from the spare
Pressure and Tank ports on the PLA
valve block.
4. Insert the 6MJ-8MB fittings (F03) into
the spare P and T ports on the PLA valve
block.
5. Connect hoses H01 (P and T lines), into
the ports on the sprayer valve block
where the 6MJ-6MB (F03) fittings are
located.
6. The existing hoses that run to the boom
tilt cylinders should be disconnected
from the sprayer valve block and
reconnected to the NORAC valve block.
7. The “raise” lines must be connected to
the "B" ports of the NORAC valve
block. The ports on the sprayer block
must then be capped with 4FJCN caps
(F02).
8. The "A" ports of the NORAC block
must be connected to the “lower” lines
of the cylinders. The ports on the sprayer
block must then be capped with F02.
It may be necessary to use the
supplied extension hoses (H02) and
4MJ-4MJ fittings (F04) to extend
the left tilt cylinder hoses.
