INTRODUCTION
Congratulations with your new LH 1200 sprayer monitor.
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
1200 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
This manual may not be altered, copied or manipulated in any way. Unoriginal

GENERAL USE
The LH 1200 is especially designed for use on a crop sprayer.
The following primary 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 (litre counter)
The monitor can also be used in connection with other implements by encoding
some special values (codes).
PERATORS

& F
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 be placed into the following implement related sets:
FERTILISER DISTRIBUTOR
Type A: Type 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

The above examples show that three basic functions Work time, Forward speed,
and Area counter 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 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 1200 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 26.

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.

AREA COUNTERS
The area counters start and stop automatically when the implement is
in work/not in work (implement sensor), and continue to count regardless of what
other function in the “primary functions“ has been selected.
Area is not being measured if an “r” is displayed on the screen.

PERATING THE
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.
The area trip counter counts synchronically with the area total counter.

Area total counter:
Pressing this key 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.
