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
example, any of the following:
 Disturbance to/from any electronic services or products that do
not confirm to the standards for CE marking,
 Missing or poor signal coverage or a succession hereof from
external transmitters/receivers, used by the buyer,
 Functional faults, which apply to or from a PC-program or PC-
equipment, not delivered by the seller,
 Faults that may arise from the buyers negligence to react to
warnings and fault messages from the product, or which can be
traced to negligence and/or absent constant control of the work
carried out in comparison to the planned job.
7.2 When implementing any new equipment the buyer must take great care and
pay attention. Any doubts as to correct operation/use should result in
contacting the sellers service department.

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
A: B:
Work time Work time
Forward speed Forward speed
Area trip counter Area trip counter
Area total counter Area total counter
Shaft speed (RPM) Fertiliser application rate
Fertiliser consumption
Fertiliser APPLICATION RATE and CONSUMPTION are only possible on fertiliser
distributors fitted with feed rollers.

SEED DRILL
A: B:
Work time Work time
Forward speed Forward speed
Area trip counter Area trip counter
Area total counter Area total counter
Shaft speed (RPM) Seed application rate
Seed consumption
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.
