* Some items may not be included in your kit.
NOTICE:
Every effort has been made to ensure the
accuracy of the information contained in
this manual. All parts supplied are
selected specially to fit the sprayer to
facilitate a complete installation.
However, NORAC cannot guarantee all
parts fit as intended due to the variations
of the sprayer by the manufacturer.
Please read this manual in its entirety
before attempting installation.
ATTENTION:
When installing the UC4+ System please
be aware that at a point in the installation
your sprayer booms will be inoperative
until the installation is complete. Any
installation procedure requiring boom
movement will need to be done first.
Once the hydraulics have been
disconnected you must complete the
electrical installation before the booms
become operative.

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.
