BoomControl
WARNING
Danger caused by unexpected movements
in automatic mode. Never come close to the
ultrasonic sensor, while the BoomControl is
in automatic mode!
When operating the sprayer under high
voltage power lines disable the BoomControl
and operate the slope compensation
manually!
No persons may be present under the folding
boom and in the danger zone!
The BoomControl function must be disabled
when leaving the cab!
The BoomControl folding boom control is used
for the automatic distance control of the spraying
boom.
Ultrasonic sensors measure the distance to
the ground or the crop and the folding boom is
then adjusted in accordance with the nominal
distance values. An automatic height and
inclination control thus adapts the folding boom
distance to the crop. The crop should be closed
and not show any gaps.
The scanning width of a sensor is approx. 0.5 m.
If a gap in crop or a trench wider than 0.5 m is
detected under a sensor, the corresponding
boom segment will be lowered (danger of
damages).
When passing over very smooth surfaces, such
as e.g. water puddles, the ultrasonic signal may
be reflected. The control must in these areas be
deactivated.
¾
BoomControl does not relieve the driver from
his responsibility to constantly check the
position of the folding boom and to interfere
manually, if needed!
The folding boom can be equipped with up
to 6 sensors for height adjustment and slope
compensation.

NOTE
When the spraying boom is switched off at the
headland, the spraying boom is automatically
raised by a previously defined value.
When switched back on, the spraying boom will
return to its set height.
BoomControl modes
Various equipment versions are available.
Depending on the mode, there are different
designs.
BoomControl ECO
Design with 2 or 4 sensors for height adjustment
and slope compensation.
BoomControl Pro
Design with 4 or 6 sensors for height adjustment,
slope compensation and angle adjustment.
BoomControl ProPlus
Design with 6 sensors for height adjustment,
slope compensation and angle adjustment of
the outside wings.
NOTE
In case of irregular population and/or empty
spaces in the population, the folding boom
control must be deactivated or manually overrid-
den to avoid unintended lowering of the folding
boom!
