- press button 3 (figure 4.2.4) for a short time. There starts an automatic tryout of
programme No.2: the plough is uplifted from the operating position, the plough width is de-
creased up to minimal and the plough is turned to the extreme opposite position (from right
to left). In the upper (transport) position of the plough, it is required to deflect any of joy-
sticks from the neutral position to the control side for a short time on the section involved in
the programme. Indicators 8, 9 display “PAU” (pause), annunciator 6 for engaged pro-
gramme No.2 starts blinking (programme tryout stops for a time). After tractor turning (the
plough is in transport position) and entering a new run, it is required to press button 3 for
programme No.2 again to finish (continue) its tryout. The plough continues its further turn
to the right (into the operating position), the plough width is increased, the plough is low-
ered into the operating position;
- when entering the run, it is required to provide lowering of the plough front part
from control console for rear lift linkage 32 (figure 2.1.1) as this operation can not be pro-
grammed in OPU for HLL;
- when going out of the run, it is required to provide uplift of the plough front part
from control console for rear lift linkage as this operation can not be programmed in OPU
for HLL;
- short-time pressing button 4 (figure 3.2.7) starts execution of programme No.1: the
plough is uplifted from the operating position, plough width is decreased up to minimal, the
plough starts turning from left to right. In the upper (transport) position of the plough, it is
required to deflect any of joysticks from the neutral position to the control side for a short
time on the section involved in the programme (programme tryout stops for a time). After
tractor turning (the plough is in transport position) and entering a new run, it is required to
press button 4 for programme No.1 again to finish its tryout, preliminarily lowering the
plough front part from control console for rear lift linkage 32 (figure 2.1.1), etc.
3.2.12.3 Example of control operations programming for a seeding machine by
means of OPU for HLL
While control operations programming for a seeding machine, it is necessary first to
take into consideration seeding machine requirements set forth in its operation manual.
The algorithm for seeding machine control shall be made with regards to requirements for
its control while entering the run and going out of it.
This clause provides information on the variant of tractor operation coupled with
seeding machine, the hydraulic fan drive motor of which is connected with section No.1,
cylinder distributive valve for markers uplift-lowering – to section No.2, cylinder for seeding
machine uplift-lowering – to section No.3.
For operation in the automatic mode, it is required to program three programmes.
To carry out control operations programming for a seeding machine, it is required to
switch on OPU for HLL 3 (figure 3.2.7) by pressing button 1.
Programme No.1 provides engagement of hydraulic fan drive motor.
To record programme No.1 it is required to do as follows:
-
press button 4 (figure 3.2.7) and hold it in a pressed position until an audible sig-
nal gets activated (about two seconds) and annunciator 5 starts blinking;
-
press selection button 15 for distributive valve EHS section No.1. Annunciators
for uplift and lowering 10 of this section shall start blinking;
- when controlling on section No.1, using joystick 1 (figure 3.2.6), deflect it back-
wards to the level corresponding to the required fan revolutions. Holding joystick 1 in this
position, press button 15 (figure 3.2.7) with the other hand, and then button 4.
Programming for fan drive control is completed.
On tractors equipped with the electronic joysticks unit BED-01, programming for en-
gagement of the hydraulic fan drive motor can be carried out by means of a joystick with-
out OPU for HLL. For doing this, when controlling on section No.1, deflect joystick 1 (figure
3.2.6) backwards to the position corresponding to the required fan revolutions and, holding
it in this position, press the button on the joystick (from above), after which set the joystick
to the neutral position.
