automatically
FLOW-FIGURE
This is the "calibration-figure" for your flowmeter.
In other words: The measuring accuracy of the liquid! You MUST calibrate your
flowmeter. Recalibrate the flowmeter if the consistency of the liquid used changes.
FLOW CALIBRATION
Encode (LH20 D meter) a "start" figure of 2000.
Method 1. (The computer calibration-mode)
(Just follow this instruction and those on the screen)!
1. Fill the tank, or minimum 600 litres.
2. Encode the filled quantity in “LITRE LEFT”, and return to “Flow figure”.
3. Spray minimum 500 litres (All boom sections open, keep within normal
pressure range (e.g.3 Bar). You may keep the machine stationary, using the
simulated speed facility, (see "SYSTEM") or select “MANUAL” and set your
pressure (see page 13).
4. Verify the remaining litres in tank on the tank scale! (Note: machine must be
level).
5. Place the cursor on “TANK LIT” and encode the amount remaining in the
tank.
6. Press the flashing "CALC. FLOW"- key!
7. The new flow-figure is now calculated and automatically encoded.
NOTE! If you should be uncertain regarding the accuracy of the tank-scale, it is
recommended to take the machine to a weigh- bridge for verification.
16 LH A
GRO
Page 17
LH 4000 O
PERATORS MANUAL
Method 2: (Manual calibration method).
Your flow-calibration figure may be calculated as follows:
1. Fill tank with minimum 600 Litres.
2. Reset your "LITRE" counter (using the "DATA DELETE" menu).
3. Spray minimum 500 litres (All boom sections open, keep within normal
pressure range (e.g.3 Bar). You may keep the machine stationary, using the
simulated speed facility, (see "SYSTEM") or select “MANUAL” and set your
pressure (see page 13).
4. Verify the remaining litres in tank on the tank scale (Note: machine must be
level).
5. Verify your "LITRE" recorder reading in the "DATA/DELETE" menu.
6. Calculate your correct flow-figure, using this formula:
NEW FLOW-FIGURE
Present flow-figure x sprayed amount
=
Litre recorded on computer
E.g.:
2000 x 500
487
= 2053
The calculated new figure must be encoded in the computer.
BOOM WIDTH
The effective width of your sprayer (in cm.)
The LH 4000 computer automatically compensates for open and closed boom
sections.
Consequently each individual spray-sections must be encoded into the computer.
Encode the widths one by one. Start with the left-hand side (section 1).
Proceed thus:
Move cursor to first section. Enter width (in Cm.) using the numeric keypad.
Proceed to section 2 -3 etc!
DRIVE FACTOR
The "response-factor" for automatic application control mode. This parameter sets
the "speed" of the reaction time of regulation. (e.g. Sprayer press regulation valve)
If the reaction is too slow = increase figure or vice-versa. Min fig. = 1. Max.= 500.
"Normal" status, Start with 50.
REGULATION DELAY
Encode the number of seconds that regulation is delayed by after the main valve is
opened. It is possible to encode from 0 to 9 seconds.
GRO 17
LH A
Page 18
LH 4000 O
PERATORS MANUAL
UNIFORM PRESSURE
Encode whether the controls of the sprayer are equipped with uniform-pressure
valves (balance return-valves), or not.
ON = Yes OFF = No.
If "ON" remember to adjust your valves.
SPEED SENSOR (WHEEL TRACTOR, WHEEL SPRAYER)
You can chose between two different located speed sensors:
WHEEL TRACTOR
Sensor fitted to the tractor. Either externally, or an integrated (gearbox) sensor.
(May apply e.g. if machine is self-propelled type).
WHEEL SPRAYER
Sensor located on the sprayer. (e.g. trailed sprayers).
Calibration of speed sensor. Sensors must be calibrated individually!
SPEED SENSOR CALIBRATION
Speed sensor calibration is extremely important! We recommend that you check
the sensor calibration during the season. (This will ensure of compensation for
tyre-wear.)
However, the design of the LH 4000 makes calibration easy. You can calibrate
using two methods; Automatic or Manual.
AUTOMATIC SPEED SENSOR CALIBRATION
1. Carefully, measure and mark a distance of 100
metres. (Not on tarmac, but field-condition soil
surface)
2. Drive to "start" position of the 100-m distance,
and press the "CALIB.CALC" key. The screen
to the left will appear:
3. Drive the 100-metre distance. Stop exactly at the
100-m. mark.
4. A new function-key will appear; "CALC.
WHEEL". Press this key, and the computer has
automatically calculated and entered the
calibration figure!
Should the flashing: "CALC. WHEEL" however
not appear, the computer has received
insufficient pulses from the sensor enabling it to
"auto-calibrate". You must calibrate using one of
the two "manual" alternatives:
18 LH A
GRO
Page 19
LH 4000 O
PERATORS MANUAL
"MANUAL" SPEED CALIBRATION.
E.g. when sensor is fitted to a wheel:
1. Mark the wheel (e.g. the valve), and mark the field.
2. Drive the machine exactly 10 revs, of the wheel.
3. Mark out on the Field.
4. Measure the driven distance carefully (to nearest cm). Calculate your
calibration figure. Use the following formula:
Example:
The measured distance between marks = 52.80 metre (5280 centimetre)
The wheel turned 10 revs.
Four (4) magnets are fitted.
5280 (the distance driven in cm)
= 132.000 cm
10 (the revs.) X 4 (the magnets)
This figure: (132) is to be encoded. Press function-key "WHEEL TRACTOR".
Encode 1 - 3 - 2 using the numerical keypad.
Incorrect encodements can be deleted using the "C"-key.
"Manual" speed calibration e.g. sensor fitted to a prop-shaft
1. Press the function-key : "CALIB CALC". The
screen to the left will appear:
2. Move (drive) slowly. Stop when "NO OF
PULSES" changes from "0" (nil), to "1".
3. Mark the field.
4. Drive slowly. Stop when NO OF PULSES"
changes from "50", to "51".
5. Mark the field. Measure the distance between
the two marks.
6. Divide the measured distance (cm), by 50.
7. Encode the result (in cm.) using the numerical
keypad.
TANK VOLUME
The sprayer’s tank size is encoded here. This is required if the automatic tank fill
feature is to be used.

PERATORS MANUAL
METRE SWITCH
Select whether distance-recording is started/stopped manually, "MANUAL", or by
the selected override-service sensor (e.g. spray on/off switch).
INPUT SET-UP
The LH 4000 software allows for a flexible set-up of electric connections to ANY
TYPE of Crop-Sprayer controls. Select either: "MAIN-VALVE" or "BOOM
SECTION”.
The screen will read the current status. You may change setting by using the
"Shut/Open OV." (volt)-key.
E.g.: Boom section “Shut” OV.
States that the wires connected to the boom section switches receive “OV”
(ground), when the switch is in the “OFF” position.
This should be set by the engineer when the system is fitted.
RPM SENSOR
Select weather a RPM sensor is fitted and encode the number of pulses received
per revolution.
NOTE! This function is not implemented in all sprayer fitting kits, ask your
dealer.
WARNING ENCODE
KM/H: Warning ON/OFF and MAX/MIN. limits for speed warning.
NOTE! Activation of the speed warning provides and ensures
minimum spray output when the speed-warning is given
for the “low” limit setting. E.g. when the speed falls
below that set in KMH warn the spray pressure will be
maintained.

NOTE! This is an optional feature that requires specific parts to be fitted to your
sprayer. Ask your dealer for details.
The "HOLD" key gives instant access to the Tank Fill
features:
FILL
VOLUME: The amount required to be filled. This
is calculated through the "litre rest Ha rest, the tank-size, and the present
application rate"
FILLED

FILL-FLOWMETER CALIBRATION
NOTE! The Fill-flowmeter is an independent unit. Subsequently it MUST be
calibrated individually!
However, as automatic calibration-mode is provided by your LH 4000 for the
spray-flowmeter, so it is for your FILL-meter!
The accuracy of the calibration procedure depends on the amount used for
calibration. The following example uses 1000 litres.
Please double-check the calibration of the fill-flowmeter.
Proceed thus:
1. Select "FLOW-FIGURE" through the sub-menu.
2. Check that a figure is encoded. If not, enter e.g. 4000.
3. Press the "return"-key to return to the previous screen.
4. Enter a "FILL VOLUME" Enter approx. twice the amount you may require.
5. Press the "START FILL" key in the sub-menu.
6. Fill the tank with an exact "known" amount (through the fill flowmeter). (You
may use a weigh-bridge for optimal accuracy).
7. Select "FLOW-FIGURE" in the sub-menu. Move cursor to "TANK LITRE".
Encode the amount here.
8. Press the flashing "CALC. FLOW" key. The flow-figure will be calculated
(and entered) automatically.

SPEED SENSOR (WHEEL TRACTOR, WHEEL IMPLEMENT)
Your LH 4000 provides for two differently located speed sensors.
WHEEL-TRACTOR
A sensor fitted on the tractor.
NOTE! Possible wheel-slippage will interfere with accuracy unless you
compensate through with wheel calibration
WHEEL IMPLEMENT
You may desire to have a permanent sensor fitted on a trailed machine for
improved accuracy. Whenever applicable, speed sensors located on large-driven
wheels enhances accuracy.
SPEED SENSOR CALIBRATION
The LH 4000 provides an automatic-calibration-feature for the speed-sensor.
However, you may need or desire to calibrate using a "manual" procedure.
Both procedures are detailed in the "SPRAYER" section pages 18 & 19.
Calibrate your sensor as described.
IMPLEMENT SENSOR
The implement sensor is the sensor that starts and stops the area meters.
In OTHER IMPLEMENT you can choose between the following:
1. Lift (sensor connected via rear of 7 pin socket).
2. PTO (if a PTO sensor has been mounted).
3. Implement (sprayer main on/off switch starts/stops area recordings).
