Example Of Programming Operations To Control A Seeder Using The Opu Of The Hll - Belarus 3522.5 Operator's Manual

to the minimum one, the plough will rotate to the contrary extreme position (from the right
to the left). As the plough is in the upper (hauling) position it is required to deviate any of
the joysticks to the direction of controlling over the section enabled in the program. The
indicators 8, 9 will display "PAU" (pause), the annunciator 6 of the enabled program No2
will start blinking (the program implementation will temporary stop). As the tractor makes a
U-turn (the plough is in a hauling position) and starts a new run it is necessary to push the
button 3 of the program No2 repeatedly to finish (continue) its implementation. The plough
continues further overturn to the right (to the working position), the width increases, the
plough lowers to the working position;
- when entering the run it is required to lower the first part of the plough using the
RLL control console 31 (figure 2.1.1), as this operation is impossible to program with the
OPU of the HLL;
- when driving out of the run it is required to raise the first part of the plough using
the RLL control console as this operation is impossible to program with the OPU of the
HLL;
- pressing the button 4 shortly (figure 4.2.3) starts the program No1 implementation:
the plough will raise from the working position, the width will decrease to the minimum one,
the plough will rotate from the left to the right. As the plough is in the upper (hauling) posi-
tion it is required to deviate any of the joysticks to the direction of controlling over the sec-
tion enabled in the program (the program implementation will temporary stop). As the trac-
tor makes a U-turn (the plough is in a hauling position) and starts a new run it is necessary
to push the button 4 of the program No1 again to finish (continue) its implementation, hav-
ing preliminary lowered the front part of the plough using the RLL control console 31 (fig-
ure 2.1.1), etc.

4.2.8.3 Example of programming operations to control a seeder using the OPU of the HLL

Programming operations to control a seeder, first it is needed to take into account seeder re-
quirements, set forth in its operation manual. The algorithm of seeder control shall be made up with
due account for requirements to its operation at entering the run and driving out of the run.
This clause includes overview of tractor operation coupled with a seeder, a hydrau-
lic motor to drive a fan, which is connected to the section No1, a distributor of cylinders to
raise-lower markers, which is connected to the section No2, a cylinder to raise-lower the
seeder, which is connected to the section No3.
To operate in an automatic mode it is required to record three programs.
To carry out programming of operations to control the seeder it is required to turn on the OPU of
the HLL by pressing the button 1 (figure 4.2.3).
The program No1 provides actuation of the fan driving hydraulic motor.
To record the program No1 proceed as follows:
- push the button 4 (figure 4.2.3) and hold it pressed until an acoustic signal goes off (ap-
proximately two seconds) and the annunciator 5 starts blinking;
- push the button 15 to select the section No1 of the hydraulic distributor EHS. The an-
nunciators of uplift and lowering 10 of this section will start blinking;
- operating over the section No1 with the joystick 1 (figure 4.2.2), move it back to
the level corresponding to the required speed of the fan. Holding the joystick 1 in this posi-
tion, press the button 15 with your other hand (figure 4.2.3), and then press the button 4;
Now the programming of the fan drive control is finished.
On tractors, equipped with the electronic joystick unit EJU-01, it is possible to pro-
gram the actuation of the hydraulic motor to drive the fan by means of the joystick without
the OPU of the HLL. For this purpose operating over the section No1 move the joystick 1
(figure 4.2.2) back to a position, corresponding to the desired speed of the fan, and holding
it in this position press the button on the joystick (on the top), after this move the joystick to
its neutral position. The fan will rotate with the set speed until turned off (by means of re-
peated moving of the joystick 1 backward and pressing the top button).
