LH 1200S O PERATORS MANUAL
12 LH A GRO
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.
