be alert! Note the following recommended precautions and safe
operating practices.
Read and understand this instruction book before using the equip-
ment. It is equally important that other operators of this equipment
read and understand this book.
Turn electrical power off before connecting and disconnecting the
display and transducers, servicing or using a battery charger.
If an arc welder is used on the equipment or anything connected to
the equipment, disconnect power leads before welding.
Test with clean water prior to filling with chemicals.
Keep children away from the equipment.
Do not use a high pressure cleaner to clean the electronic
components.

Description
The HARDI Monitor 1500 and HARDI Controller 2500 are for use in
agricultural and horticultural production. HM 1500 is a monitor whereas
HC 2500 permits automatic control of application rate.
Main components are:
• Display
• Scanbox junction box
• Flow transducer
• Speed transducer
The matrix display has two lines permitting two lots of information to be
shown at the same time. Display readout includes dosage applied,
speed, liquid rate per minute, total covered area, total volume sprayed
and 9 trip tellers for area covered and volume sprayed. It is illuminated
internally so readout is possible even for night-time work.

4
Functions include correct area with closure of up to 8 spray boom
sections, alarm functions for dosage and minimum tank contents and
possibility for audio/visual alarm.
The transducers utilised are chosen for long service life and good
signal quality. Speed, area switch and revolutions 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.
The system has a non-volatile memory with no battery which simplifies
storage. All parameters in the menus are saved in the display’s
memory and are not lost when the power is disconnected.
The materials and electronics for the components have been devel-
oped to last many years under agricultural conditions.
Options include a 4-20 mA transducer (e.g. pressure), revolutions
transducer, area meter transducer and switch box for boom sections
when used with BK or BK/EC control unit (only for HM 1500).
Fitting the system
Please note the configuration and connections for your system.

Distance between them
must be 5 to 7 mm.
An adjustable hose clamp
drilled with a 4.5 mm hole
can be used to attach the
magnet to the shaft.
Analog transducer
Input is 4 to 20 mA.
Transducer cables are fed through the Scanbox grommets. Connection
is directly to the Scanbox circuit board.
NOTE: A 2 metre cable extension set with plugs and sockets is avail-
able. HARDI ref. no. is 741610.
Cables
All the cables and wires must be routed so they do not get pinched,
snagged or melted. The transducer cables should be shortened if
necessary.
NOTE: Although the system meets standards EN 50081-1 (1992) for
generic emission and EN 50082-2 (1995) for generic immunity, some
communication systems (e.g. 2 way radio, cellular telephones) may
cause interference with the sprayer computer. Keep communication
system units and cabling away from the sprayer computer units and
cabling. If interference is noted, avoid using the communication system.

Calibration
It is necessary to set the correct boom width and calibrate the flow and
speed transducer before using the system. Calibration of the optional
revolutions transducer is necessary if it is fitted.
Boom size
For setting of number of boom sections and width.
Correct work width for each boom section is necessary
to calculate dosage and area covered.
Method
1. Use arrow key to set number of boom sections and press menu key.
Maximum number of sections is 8. Press menu key to continue.
For mistblowers, number of sections is typically 2.
2. Use the arrow key to increase or decrease section work width.
Press menu key to continue to next boom section.
After the last section, press the accept key.
The display will briefly show the total width.
Flow calibration

19
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 Flow Tank
method is more time consuming, but is more accurate than the Flow
Nozzle method.
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.
Flow constant
To change the flow constant theoretically.
During theoretical flow calibration the number of pulses per unit are
shown on the display.
For example, [ 120.0 PPU ] indicates the number of pulses which
theoretically come from the flow transducer whilst 1 litre of liquid
passes through. Approximate PPU values for different flow housings
are as follows:
Housing Code for Flow range PPU Orifice
housing l/min value mm
BK White 5 - 150 105.0 13.5
BK & EVC One outside groove 5 - 150 120.0 13.5

Nozzle method
During practical flow calibration 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. The number of nozzles is set with the arrow key to read the actual
number of nozzles to spray. Press the menu key to continue.
2. Open all boom sections.
3. Turn the main ON/OFF valve on.
The display unit will then show the individual nozzle output per minute.
4. Using a HARDI calibration jug, check the actual nozzle output
per minute. It is recommended that an average of several nozzles
be taken.
5. 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 when
returning to the main display picture.
