Description
The HARDI PILOT 3570 Monitor is a data processor system for use in
agricultural and horticultural production. The main components are:
• HP 3570 display
• HP 3010 tractor junction box
• Transducers (sensors)
Data and power connection between the display and junction box is
done with just one coaxial cable so that all excessive wiring is avoided.
The components communicate via the HARDI LINK system.
The HP 3570 display is very compact for easy placement in the tractor
cabin and can be fitted directly on to a flat surface. It is illuminated
internally so readout is possible even for night-time work. HP 3570 can
have the following readouts:
• Driving speed
• Area treated
• Revolutions
• Actual application rate
• Flow rate
The HP 3010 tractor junction box is fitted to the tractor. It supplies
HARDI LINK with current and has the connection points for the trans-
ducers. A fuse on the current inlet protects the system from reverse
polarity and overload.
The transducers that can be connected are speed transducer, flow
transducer, P.T.O. r/min transducer and area switch. The components
utilised are chosen for long service life and good signal quality. Speed,
area switch and r/min transducer is the same component. The flow
transducer has a diode built into the housing to aid servicing. As the
rotor turns, the diode will flash thereby indicating it functions.

5
HARDI PILOT has a non-volatile memory (contains no batteries) which
simplifies storage. Factory default constants and values are already
programmed into the system. The materials and electronics for the
components have been developed to last many years under agricul-
tural conditions.

Connection of HP 3570 display
NOTE: To avoid a short circuit, the
power must be disconnected before
attaching the BNC connector plug to
the display connector jack.
The connector has a bayonet fitting.
To attach, locate guide groove, push
and turn.
Start-up of HP 3570 display
When the power is connected, a test is carried out to check all seg-
ments and symbols in the graphic display.
During the test the individual segments are switched on one by one. In
addition, all four figures in the digital displays are counted, i.e. 0000,
1111 etc. up to 9999.
While the display test is being carried out, the internal electronics are
also tested.
When the test is concluded, all symbols light up briefly after which
everything is switched off and a version number is shown. The version
number explains which programme version the display unit contains.
HP 3570 concludes the test by showing the total work (boom) width
and the number of sections which is one for this equipment. HP 3570
is now tested and is ready to operate.
NOTE: Use of sunglasses will reduce visibility of the graphic display.
NOTE: Text or symbols found or seen on the display is shown inside
the brackets; [ XX]

Calibration of flow transducer
The flow transducer can be calibrated theoretically or with two practical
methods. For the sake of accuracy, the practical methods are pre-
ferred. Practical calibration is done with clean water. The Tank method
in menu 02 is more time consuming, but is more accurate than the
Nozzle method in menu 03.
When changing to nozzles with more than a 100% increase or decrease
in output, it is recommended to re-calibration the flow transducer.
Calibration is recommended to be carried out at least once during the
spraying season.
Use the chart at the back of the book to record the values.
[ 01 ] Flow calibration - theoretical
During theoretical flow calibration in menu 01, the number of pulses
per unit [ PPUPPU] are shown on the display. For example, [ L 120.0L 120.0 ]
indicates the number of pulses which theoretically come from the flow
transducer whilst 1 litre of liquid passes through.
Method
1. Open menu 01.
2. Use arrow key to adjust PPU value.
3. Use accept key to close the menu and
return to the main display picture.
Approximate PPU values for different
flow housings are as follows:
colour code Metric US gal.
BK housing white 120.0 PPU 455.0 PPU
EC housing white 118.0 PPU 447.0 PPU
EC housing for S/67 white 128.0 PPU 485.0 PPU
EC housing black 59.0 PPU 223.0 PPU
White colour code =13.5 mm / 5/8” orifice.
Black colour code = 20.0 mm / 7/8” orifice.

[ 02 ] Flow calibration - Tank method
During practical flow calibration in menu 02, the tank is partly emptied
through the nozzles. Whilst emptying, the display calculates the quan-
tity emptied on the basis of the actual calibration value (PPU). The
quantity displayed is compared with the quantity actually dosed. This
can be according to the tank contents level indicator or by weight
difference before and after. The quantity displayed is corrected to read
the quantity actually dosed.
Method
1. Place the tank on level ground and fill up with water until the level
reaches a unique mark on the tank contents level indicator, e.g.
1000 litre / 300 gallons.
2. Open all boom sections.
3. Open menu 02 and turn the main ON/OFF valve on. [ Open AllOpen All ]
will be displayed if there is no flow. The display unit will then begin
to count the volume being emptied through the nozzles.
4. When for example, 600 litre / 200 gallons have been emptied out, as
shown by the tank contents level indicator, the main ON/OFF valve
can be turned off.
5. Correct the volume shown on the display with the arrow key to read
the volume shown on the tank contents level indicator. The display
will briefly show the new calibration value PPU (pulses per unit)
when returning to the main display picture.

[ 03 ] Flow calibration - Nozzle method
During practical flow calibration in menu 03, the individual nozzle
output on the display is compared to the actual individual nozzle
output. The output displayed is corrected to read the actual output. For
correct calibration it is necessary to know the number of nozzles on the
boom.
Method
1. Open all boom sections.
2. Open menu 03. [ nn] indicates number of nozzles and this is cor-
rected with the arrow key to read the actual number of nozzles to
spray.
3. Turn the main ON/OFF valve on. [ Open AllOpen All ] will be displayed if
the main valve is turned off.
4. The display unit will then show the individual nozzle output per
minute.
5. Using a HARDI calibration jug, check the actual nozzle output per
minute. It is recommended that an average of several nozzles be
taken.
6. Correct the output shown on the display with the arrow key to read
the average output measured with the calibration jug. The display
will briefly show the new calibration value PPU (pulses per unit)
when returning to the main display picture.

[ 04 ] Speed calibration -theoretical
During theoretical speed calibration in menu 04, first the number of
magnets on the wheel is indicated, followed by the radius of the wheel.
HP 3570 then calculates the wheel’s circumference and the number of
pulses per rotation.
Method
1. Open menu 04.
2. [ nn] indicates number of magnets and this is corrected with the
arrow key to read the actual number of magnets. Press the accept
key.
3. [ rr] indicates radius. The radius is measured from the earth up to
the middle of the hub cap. The wheel radius is corrected with the
arrow key to read the actual measured radius.

[ 05 ] Speed calibration - practical
Practical calibration of speed in menu 05 is done by driving a meas-
ured distance and correcting the display so that the actual and the
calculated distances are the same.
Theoretical speed calibration should be carried out before practical
speed calibration.
Calibration should take place in the field with a half full tank and normal
working tyre pressure in order to obtain the wheel’s real “working
radius”.
Method
1. Measure a distance not less than 75 metres / 250 feet.
2. Park the tractor at the start of the measured distance.
3. Open menu 05. Drive the measured distance.
4. Correct the distance shown on the display with the arrow key to
read the actual distance.

[ 07 ] Revolutions readout of P.T.O.
In menu 07, it is possible to see the revolutions on the P.T.O.. One
magnet is usually fitted to the shaft. The display will also show a
symbol for the TWIN fan and an auxiliary shaft but this is not relevant
to this system.
Method
1. Open menu 07.
2. Choose the [
PTO
] symbol with the arrow key and press accept
key.
3. Now a value of [ 1.01.0] is shown. This indicates that one pulse will
come per revolution. If the revolutions, for example, on a fertiliser
disc are required, it is necessary to alter the pulse number per shaft
revolution with the arrow key to get disc revolutions.

Areameter and HP 3570
Points to note if the system is fitted with
an areameter.
• The system will register covered area
when the south side of the magnet is
located directly in front of the
areameter transducer.
• When the system is used with a flow
transducer, the areameter must be
disabled. This can be done by pre-
venting the magnet from positioning in
front of the transducer or by discon-
necting the transducer.
