INTRODUCTION
Congratulations with your new LH 1200S sprayer monitor with boom
compensating features.
During development of this monitor we have made a point of producing a durable
product that is primarily developed to monitor chemical application. The monitor,
however, includes a number of other functions, which enable it to be used in
connection with almost any other implement.
If the monitor is used in accordance with the guidelines in this manual, the LH
1200S will be a true and reliable assistant for you for many years.
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:
7. Product usage.
7.1 Any use of the product is at the sole risk of the buyer. The buyer is
therefore not entitled to any form for compensation caused by, for

GENERAL USE
The LH 1200S is especially designed for use on a crop sprayer. The following
functions can be selected directly from the keypad:
1. Work time
2. Forward speed
3. Area counters (trip- and total)
4. Chemical application rate
5. Chemical consumption per minute
6. Chemical consumption (litre counter)
The monitor can also be used in connection with other implements by encoding
some special values (codes).
The secondary functions are as follows:
Distance in metres
Shaft speed (RPM)
Fertiliser application rate
Sow seed application rate
Fertiliser consumption (Kg counter)
Sow seed consumption ( Kg counter)
Unit counter
These functions can placed into the following implement related sets:
FERTILISER DISTRIBUTOR

The above examples show that three basic functions, TIME, FORWARD SPEED,
and AREA are always available. The secondary functions can be selected as
required.
The monitor can measure distance in metres as an extra function. This function
requires a special encodement (code) and can, therefore, only be used by itself.
All other information displayed is incorrect when this function is selected.
When the boom section function is activated, the display will change between the
selected function and the boom section status. The display changes every other
second.
When forward speed is selected and the area override sensor is activated an “r”
is displayed on the left-hand side of the display.
The LH 1200S is equipped with a system test program, which enables the user to
test all connected sensors. For more information, see the ”SYSTEM TEST”
chapter on page 25.

SYSTEM DESCRIPTION
The LH 1200S can be supplied with two different fitting kits. The difference
between the kits allows for greater flexibility.
The standard fitting kit (LH No. 918-123) is suitable if the monitor is only to be
used in conjunction with one implement and if you do not need to change between
several sensors.
The fitting kit with changeover switches (LH No. 916-123) is suitable if the monitor
is to be used in conjunction with several different implements. It is possible to
select between several different sensors using the changeover switches on the
junction box.
The two fitting kits itemised with part references below:

PRIMARY FUNCTIONS
WORK TIME
Key Function
WORK TIME IN HOURS AND MINUTES
Pressing this key displays the effective work time (max. 99 hours 59
minutes)
The time counter is started and stopped by pressing the key.
Flashing colon >:< means that the time counter is running.
Constant colon >:< means that the time counter is stopped.
Pressing this key for min. 3 seconds resets the counter.
FORWARD SPEED
Key Function
KILOMETRES PER HOUR
Pressing this key displays the present forward speed in kilometres per
hour with 1 decimal.
Forward speed is always displayed when the monitor is switched on.
An “r” on the left-hand side of the display under this function, indicates
that the area override sensor has been activated.
NOTE! This indicator is only displayed when forward speed has been
selected.
Forward speed is zeroed after approx. 8 second after stopping.
Remember to select the “correct” wheel sensor and encode the correct
value if a fitting kit with switches has been fitted.
LH 1200S OPERATORS MANUAL
LH AGRO 11
AREA COUNTERS
The area trip and the area total counters are placed under the same key. Area trip
is displayed the first time the key is pressed, as this is the counter most frequently
used. Pressing the key for min. 3 seconds displays the area total counter.
Key Function
AREA TRIP COUNTER
Pressing this key displays the effective worked area. Area is displayed
with 2 decimals from 0 – 99.99 ha. and with 1 decimal from 100 – 999.9
ha.
The area counter is started and stopped with the fitted area override
sensor. This ensures that area is only counted when the implement is
working.
Take care to select the “correct” override sensor if a fitting kit with
changeover switches is used.
The area trip counter counts synchronically with the area total counter.
NOTE! This key has a different function if 8888 or 9999 are encoded as
the working width.
Pressing this key for min. 3 seconds resets the counter.
AREA TOTAL COUNTER
Pressing this key for min 3 seconds displays the area total counter. The
total effective area is displayed with 1 decimal from 0 to 999.9 ha. and
without decimals from 1000 to 9999 ha.
This function can be used to sum up the worked area for a season or a
year.
The area total counter counts synchronically with the area trip counter.
NB! This key has a different function if 8888 or 9999 are encoded as
the working width.
Pressing this key again displays the area trip counter.
Pressing this key for min. 3 seconds resets the counter.
LH 1200S OPERATORS MANUAL
12 LH AGRO
APPLICATION RATE FOR SPRAY CHEMICALS
Key Function
APPLICATION RATE
Pressing this key displays the present application rate in litres per ha.
The calculated application rate is based on the flow through the flowmeter
and area metering. Thus, the application rate can only be displayed if the
spryer is in operation and the machine is moving forward.
Correct performance presupposes correct calibration of the flowmeter
(see page 22). Flowmeter calibration should be checked at regular
intervals.
Remember to select the flowmeter and encode the flow figure for a
flowmeter if the machine is fitted with a fitting kit with changeover
switches.
NOTE! This key has a different function if 9999 has been encoded as
the flow figure.
BOOM SECTION COMPENSATION
The LH 1200S has a manual boom compensation feature allowing you to switch
the individual boom sections on and off when they are on/off on the sprayer using
the keypad. The display changes once every second.
The above example shows that sections 3,4,5 and 6 are open. The LH 1200S only
allows sections to be closed in succession from one of the sides (or from both
sides). A section in the middle of the boom cannot be shut off by itself.
The sections are “switched” on and off using the numerical keys. The keys have a
double function (toggle), i.e. if section 1 is open it can be closed by pressing the
numerical key 1 if section 1 is closed it can be opened likewise by pressing the
numerical key 1.
Example:
Let us assume that the above display is for a 6-section sprayer of which sections 1
and 2 are closed and sections 3, 4, 5,and 6 are open. The following is possible:
Section 2 can be opened by pressing the numerical key 2.
Sections 3 and 6 can be closed by pressing the numerical keys 3 and 6
respectively.
If the area override sensor is activated (sprayer is closed) the monitor will
automatically return to calculating with the full boom width.
The individual section sizes are encoded separately see the chapter on section
encodement, page 20.
The boom section function will be displayed regardless of which function (white
keys) has been selected.
LH 1200S OPERATORS MANUAL
LH AGRO 13
SPRAY CHEMICAL CONSUMPTION PER MINUTE
Key Function
LITRE PER MINUTE
Pressing this key displays the liquid flow through the flowmeter. The
amounts shown must not be confused as pump capacity, as there is a
return flow to the tank before the flowmeter.
Correct performance presupposes flowmeter calibration (see page 22).
Flowmeter calibration should be checked at regular intervals during the
season.
Remember to select the flowmeter and encode the flow figure for the
flowmeter if a fitting kit with changeover switches has been fitted.
SPRAY CHEMICAL CONSUMPTION
Key Function
LITRE COUNTER
Pressing this key displays the total consumption of spray chemicals in
litres.
Correct performance presupposes flowmeter calibration (see page 22).
Flowmeter calibration should be checked at regular intervals during the
season.
Remember to select the flowmeter and encode the flow figure for the
flowmeter if a fitting kit with changeover switches has been fitted.
NOTE! This key has a different function if 9999 is encoded as a flow
figure.

SECONDARY FUNCTIONS, FERTILISER DISTRIBUTOR
There are two different function sets available for fertiliser distributors, depending
on which type of spreader is being used.
As mentioned before, the functions TIME, FORWARD SPEED, and AREA
functions are always available and operate in the same way as described in the
PRIMARY FUNCTIONS section of this manual.
RPM FOR DISC SPREADERS
Encoding a flow figure of 9999 alters the program in the LH 1200S allowing it to
display RPM. RPM is displayed by pressing the L/Ha. key.
ENCODE:
Press the shown keys in this order.
Key Function
RPM
NOTE! The L/MIN key and the L key cannot be used when this
encodement is used.
FERTILISER DISTRIBUTOR WITH FEED ROLLER (PNEUMATIC)
It is possible to meter the “flow” of fertiliser on this kind of fertiliser distributor using
a special sensor, which gives a suitable number of pulses per revolution.
By encoding the calibration figure as a flow figure, the following functions are
available:
ENCODE:
XXXX is the determined calibration figure in
grams with 2 decimals. Thus, a calibration
figure of 15.00 is encoded as 1500. The
displayed application rate will be in Kg.
Key Function
FERTILISER APPLICATION RATE
FERTILISER CONSUMPTION PER MINUTE
TOTAL FERTILISER CONSUMPTION
NOTE! It is a condition for the above functions that the sensor is correctly
calibrated. A new calibration must take place if the spreader settings
are altered.
LH 1200S OPERATORS MANUAL
LH AGRO 15
SECONDARY FUNCTIONS, SEED DRILL
Exactly the same functions can be achieved for seed drills as described above for
fertiliser distributors. The functions require the same sensors and the same keys
are used.
SOW AXLE RPM
Encoding a flow figure of 9999 alters the program in the LH 1200S allowing it to
display RPM. RPM is displayed by pressing the L/Ha. key.
ENCODE:
Press the shown keys in this order.
Key Function
RPM
NOTE! The L/MIN key and the L key cannot be used when this
encodement is used.
SEED RATE MONITORING
It is possible to meter the “flow” of seed using a special sensor, which gives a
suitable number of pulses per revolution. The calibration figure is determined
during the normal calibration procedure for the seed drill.
By encoding the calibration figure as a flow figure, the following functions are
available:
ENCODE:
XXXX is the determined calibration figure in
grams with 2 decimals. Thus, a calibration
figure of 15.00 is encoded as 1500. The
displayed seed rate will be in Kg.
Key Function
SEED RATE
SEED CONSUMPTION PER MINUTE
TOTAL SEED CONSUMPTION
NOTE! It is a condition for the above functions that the sensor is correctly
calibrated. A new calibration must take place if the spreader settings
are altered.

SECONDARY FUNCTIONS; SLURRY SPREADER
APPLICATION RATE MONITORING
Flow metering is possible on slurry spreaders either by using a flowmeter
(electromagnetic) or by a RPM sensor fitted to a positive displacement pump
(exact volume per revolution).
By encoding an amount in kilos (with 2 decimals) per impulse as a flow figure the
following functions are available:
ENCODE:
XXXX is the known calibration figure in kg with
2 decimals. 5.00 kg is encoded as 500 The
application rate will be shown as m3/ha.
Key Function
SLURRY APPLICATION RATE
SLURRY CONSUMPTION PER MINUTE

functions are unusable.
ENCODE:
Press the shown keys in this order.
Key Function
DISTANCE IN METRES
NOTE! The maximum distance is 9999 metres.
LH 1200S OPERATORS MANUAL
18 LH AGRO
ENCODING
FORWARD SPEED CALIBRATION (WHEEL CIRCUMFERENCE)
Key Function
WHEEL CIRCUMFERENCE
The distance in centimetres that is driven per pulse from the speed sensor is
encoded here.
Depending on which vehicle is used the speed signal can come from a sensor built
into the gearbox, from a sensor fitted by the prop. Shaft (4-wheel drive) or from a
sensor fitted by one of the wheels.
The LH 1200S features an automatic speed calibration procedure, which can be
used for integrated or prop. Shaft sensors. The automatic calibration procedure
can also be used for normal wheel sensors if the wheel circumference does not
exceed 100 cm when divided by the number of magnets.
NOTE! It is recommended to fit as many magnets on the wheel as necessary to
ensure that the encoded wheel circumference does not exceed 100 cm.
AUTOMATIC SPEED SENSOR CALIBRATION
1. Measure a distance of 100 m and drive to the start mark.
2. Press the “WHEEL CIRCUMFERENCE” key once. Release the key and then
press and hold the key down until “AUTO” is displayed. Press the “WHEEL
CIRCUMFERENCE” key again and the monitor is ready for automatic speed
sensor calibration.
3. Drive the 100-metre stretch and stop exactly at the stop mark. The monitor will
count the number of pulses received from the sensor.
4. If the monitor has received enough pulses from the sensor (over 100 pulses
per 100 metres), it will calculate the effective wheel circumference when the
“WHEEL CIRCUMFERENCE” key is pressed again. The calculated value is
shown on the display.
If the monitor has not received over 100 pulses over the 100-metre stretch, it will
display 0 after pressing the key. One of the following two methods can be used
hereafter:
a: Manual measuring of the value to be encoded as described below
b: Fitting more magnets to increase the number of pulses per 100 metres.
REMEMBER! It is important that the distance between the magnets is the
same. Otherwise, the displayed speed will fluctuate.
LH 1200S OPERATORS MANUAL
LH AGRO 19
MANUAL SPEED CALIBRATION
1. Mark the field and the tyre.
2. Drive forward until the wheel has turned 10 times.
3. Mark the field again.
4. Measure the distance between the two marks and divide by 10. The result is
the effective wheel circumference.
5. Divide the effective wheel circumference by the number of magnets fitted.
Encode the result in centimetres with 1 decimal, 2.535 m is encoded as 253.5
cm. the maximum value that can be encoded is 300.0 cm.
NOTE! Remember to count wheel revolutions on the wheel that the magnets are
fitted.
WORKING WIDTH AND BOOM SECTIONS
Key Function
WORKING WIDTH
This encodement value is divided into main encodement values – the total
working width – and some sub-encodements – quantity correction yes/no,
when the individual boom sections (the width of) are turned off.
Procedure:
As all of these encodements are placed under the same key, the program has
been constructed so that you can page through the encodements by repeatedly
pressing the working width key. The total working width can be encoded after a
short press on the key. It is not necessary to encode further if you are not working
with boom sections.
If you want to work with boom sections pressing the key again for min. 5 seconds
will allow you to encode the boom section width.
1. ENCODING THE WORKING WIDTH
Press the keys in this order. XXXX
states the actual working width in
centimetres. (4 metres = 400
centimetres)
LH 1200S OPERATORS MANUAL
20 LH AGRO
2. ENCODING BOOM SECTIONS WIDTHS
Key Operation
Press this key.
Press and hold the key for min. 5 seconds until the following is displayed:
QUANTITY CORRECTION
This display states the first value for section encodement. This value is not a
section width, but tells the monitor to deduct a value corresponding to the section
width from the litre counter when the individual section are switched off.
Only 1 or 0 can be encoded.
If 1 is encoded the monitor will reduce the litre counter by an amount
corresponding to the width of each section that has been switched off (return to
tank after the flowmeter).
If 0 is encoded no reductions will be made when sections are switched off (return
to tank before the flowmeter).
EXAMPLES:
If you are working with a sprayer fitted with a valve manifold with balanced returns,
where the volume through the flowmeter is the same, as long as the return valves
are correctly setup, regardless of whether the individual sections are open or
closed then encode 1. If 1 is not encoded the litre counter will be incorrect, and as
the area counter is also reduced, the displayed application rate (L/Ha.) will be
incorrect.
If a flowmeter is being used on a sprayer without balanced returns the amount
passing through the flowmeter is the same as the amount being sprayed, even
when boom sections are closed. If this is the case then encode 0. If 0 is not
encoded the displayed amounts will be incorrect.
