5300 Installation and Setup Instructions 6
Hardi Loom installation (AC-5003-H-00)
The implement loom runs between the drawbar and the Pilot computer on the sprayer. Follow
the steps below to install the implement loom.
1. Run the implement loom along the existing Hardi loom and tie down firmly avoiding contact
with any sharp edges.
2. Cut the cable approximately 500mm past the Pilot Computer Box. Turn Off Power on your
Spray controller before cutting any Wires!
3. Remove box cover.
4. Remove one of the rubber grommets.
5. Cut about 10mm off the end of the grommet leaving a hole slightly smaller than the cable.
6. Push the grommet 300mm up the cable, thread it into the box then push it back into place.
7. Remove 150mm of the outer insulation to expose all 12 wires. The wires in the loom are
numbered 1 to 11. There is also a green/yellow wire. All 12 wires must be connected to
wires on the Hardi Pilot. Read the instructions below to connect wires to the Hardi Pilot.
Study the table and diagram on the following pages carefully before removing or cutting wires.
Wiring on particular machines may vary between different models, the table shown below allows
you to test the wiring layout before installation.
It is recommended to test which wires on the sprayer loom provide the signals required by the
5300 NG box. When testing for the voltage signal from the Hardi sprayer loom, be aware that
the controller will only supply voltage for 30 Seconds to operate the valve, so testing will require
assistance from another person.
Testing requires putting a multimeter across the paired wires from each valve within the Hardi
Pilot box located on the boom spray. When the valve is switched On, +12V or –12V will show
on the multimeter. If the multimeter displays 12V, the terminal which is connected to the red
multimeter lead is the “12V on” terminal for that section valve. If the multimeter displays –12V
the terminal, which is connected to the black multimeter lead, is the “12V on” terminal for that
section valve.
The paired terminal next to the 12V on terminal is the 12V off terminal. When the 12V on and
12V off terminals are established for each valve then the appropriate wires from the 5300 loom
(see wiring table) can be spliced to the Hardi sprayer loom.
Splicing Wires together
Supplied are 12 (3.5mm) female crimp connectors.
• Remove the current Hardi terminals, cut off the crimp connector.
• Strip back both wires, (wire 1 Hardi, wire 1 loom).
• Splice both wires together and crimp on a new terminal.
• Carefully slide the terminal back into place.
TIP: Remove and reconnect one wire at a time to avoid confusion!
