LH 4000 OPERATORS 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 functionkeys (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:
ACTUAL SPEED
WORK EFFICIENCY
AREA WORKED
REMAINING AREA

THE DISPLAY
The screen is divided in two sections. The upper section is the information screen.
The lower relates to the softkeys.
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 display the "main menu". Should you have selected an other screen, press the return-key until the "main menu" is displayed again:

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!

OPERATOR SELECTABLE FUNCTIONS
TRACTOR FUNCTIONS
METRE IN
TRACK: The distance recorded in the current track (tramline).
METRE: Recorded total metres
METRE START/
METRE STOP: Manual start/stop of distance counter.
BATT.: |
Battery voltage |
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."
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.
