INTRODUCTION
Congratulations with your new LH 4000 Spray Controller!
The product is a specifically developed spray controller based on the latest
available technology. We are confident that it will serve you to your full satisfaction
in the years to come.
The computer provides you with a comprehensive selection of valuable
information’s not only when spraying, but in conjunction with all field work where
its facilities for speed and area recording etc. may be desired.
We have endeavoured to deliver a fault free product. To ensure optimal use of the
equipment we ask that great attention be paid when reading the manual. We are
more than happy to help should any queries arise, both when the product is used
for the first time and at any later date. Regarding responsibility for use of the
product we refer to our sales and delivery terms especially paragraph 7, which
follows:

PERATORS MANUAL
GENERAL USE
The LH 4000 is (specifically) designed for crop sprayer control.
The software design is consequently designed for easy use and access for the
operator in conjunction with spray work.
The computer communicates with you through the screen in clear language.
Minimum use of this manual is therefore required.
BEFORE USE
It is essential that you make yourself familiar with the keys and their use. Please
read carefully and study the following pages.
Unfold the back page, which shows the fascia of the computer.
You communicate with the computer using only 5 keys.
You will appreciate that the screens relating to the four upper function- keys
(softkeys) change, as you proceed.
The screen shows the present significance of each individual key. The lower
"enter/return-key" allows you to return to the previous screen.
TRACTOR-INFO
This key instantly displays:

working under dark or sunny conditions.
NOTE! The screen may go dark in extreme hot or
cold conditions. The display will return to
normal when the working temperature of the
monitor is back to normal.
To adjust the screen contrast; Use the +/- keys.
If you want an instant return to any screen, press this
key before you scroll to another screen. The memokey allows for instant return to the memorised
screen.
TANK-FILL CONTROL

SCREEN LIGHT
This key activates the "FILL" feature, which is
detailed later in this manual.
Only active in conjunction with encoding. Will erase
any incorrectly entered figure.
Switches the back-light on and off.
NUMERIC KEYS
Only active when encoding values, or when
simulating forward speed.

THE DISPLAY
The screen is divided in two sections. The upper section is the information screen.
The lower relates to the softkeys.
PERATORS MANUAL
THE INFO-SCREEN:
You will appreciate the information screen is
designed by the manufacturer and cannot
be altered by you.
THE LOWER (SOFTKEY) FUNCTIONSCREEN:
The actual significance of the four keys is
displayed. You will notice that this status
changes as you proceed. (see the following
examples)
BASIC "MENU"-SCREEN
When powered up, the screen will light up and

PERATORS MANUAL
IMPORTANT! IMPORTANT! IMPORTANT!
The software program does not allow menu changes whilst the machine is moving.
This is to prevent operator mistakes and incorrect recordings.
"STATUS" SCREEN
Any time the "operation-menu" is selected, or you leave any encode menu, the
status screen will appear. Here all the current encoded values will be shown.
CHECK & ACCEPT the values before proceeding, by pressing the enter/returnkey.
NOTE! Before start remember to cancel (reset) all relevant counters. (Area-litre
etc.) using the "DATA/DELETE" function, if required.

SPRAYER, OPERATION
Two "Status screens" must be accepted. Press the "Return-key" until the following
screen is displayed
PRE-DEFINED FUNCTIONS
DOSAGE (APPLICATION)
The primary function under sprayer is dosage. The dosage (application rate) is
shown in Litres per Hectare, calculated as a result of the flow through the
flowmeter, the speed and the recorded area. Subsequently no reading will show if
the machine is stationary, or if there is no flow through the flowmeter.
Two arrows in the upper left corner of screen indicate the length and status of
control signals to the pressure regulator.
NOTE! The shown application rate (L/Ha) is dependent of a correct calibration of
wheel/ circumference/flow-figure/working width. (Details later in this
manual).
SPRAY-BOOM INDICATOR STATUS
The number and position of active/inactive boom-sections is shown on the screen.
SPEED
The forward speed is displayed in km/h. (One decimal).
NOTE! Ensure you select the correct sensor. (Wheel tractor, Wheel sprayer)
Radar is not available!

METRE IN
TRACK: The distance recorded in the
current track (tramline).
METRE: Recorded total metres
METRE START/
METRE IN TRACK:
The distance recorded in current track. You may use this function to locate a
position in the track (e.g. the spot where the tank ran empty).
This function is related to the "REDUCE TRA. M." (This function is only visible
whilst the sprayer is inactive.)
The "METRE IN TRACK"-counter is reset to NIL, each time the sprayer is shut
(e.g. at headlands).
However, should you shut the sprayer in a track, the computer memorises the
distance driven! And displays "REDUCE TRA. M."
METRE STOP: Manual start/stop of distance
counter.
BATT.: Battery voltage
NOTE! Should you stop spraying at a position you would like to relocate, (E.g. if
you need to refill your tank) Proceed thus:
After refilling your tank drive to start of track (headland border). Press
"REDUCE TRA. M" and drive along the tramline. An audible and visual
warning will be given 5 metres before the location at which the tank ran
empty.
When the position is instruction is given to start spraying.
METRE.:
The total distance driven in metres.
This is measured with the wheel with the speed sensor fitted. You may choose
"manual" start/stop of counter. Or automatically via the override sensor (sprayer
main valve) switch. Select your mode in: "ENCODE" "METRE SWITCH".
or:
METRE START/ METRE STOP:
Manual Start/Stop of metre counter. The start/stop selection screen will only
appear if “MANUAL” has been selected in “ENCODE”.
BATT.:
The current voltage of battery.

SPRAY FUNCTIONS
LITRE: Amount consumed from tank.
LITRE LEFT: Amount remaining in tank.
LITRE/MIN.: Litre consumption per minute.
LITRE: The total amount consumed since counter was reset. This function
is a "trip-counter", which may be reset using the "DATA/DELETE"
function. The "grand total" counter is also available in this menu.
LITRE LEFT: The amount of liquid in tank. However, this feature requires
encoding the tank volume/amount filled, before starting. This is
done in encode “LITRE LEFT”. This value is automatically
entered is the optional tank fill feature is used.
LITRE/MIN.: The actual flow in Litres per minute through the flowmeter. Do not
regard this as the Pump-capacity.
Pressing the "NEXT PAGE" key displays the next functions.
+xx %: Increase of application rate.
-xx %: Decrease of application rate.
DOSE-RATE/
NORMAL: Encodement of application rate, OR
instant return to normal rate (+/- %
activation)
+ xx %: Percentile increase of the application rate. You select the percent
figure you require, in encode "STEP%"
- xx %: Percent decrease of application rate. (similar figure will be entered
automatically, ref. the above).
NORMAL/
DOSAGE: Multifunctional softkey.
It will read "DOSE-RATE" normally. Select, and you will have
instant access to enter or alter your desired application rate.
However, should you have activated either your "+" or "-" %-
keys, the softkey will read "NORMAL". Subsequently, pressing
this key will return your application rate to "normal" regardless
what over/under rate you are currently applying.
