Figure 4.2.4 – Diagram of the hydraulic distributor section control with joysticks (manual
mode)
Note – the figure 4.2.4 presents a diagram of the hydraulic distributor section control
with the electronic joystick unit “BOCORO”. The diagram of control with joysticks of EJU-1
is similar to the diagram in figure 4.2.4. Rules for actuation of the floating position for both
types of joysticks are provided in subsection 2.16.2 “Electronic joystick unit”.
4.2.8.2 Example of programming operations to control a reversible plough by means
of OPU of the HLL
In this clause a variant of tractor operation coupled with a reversible plough is ana-
lyzed, when a cylinder, providing plough overturn, is connected to the section No1, a cylin-
der, providing measurement of plough width, is connected to the section No2, a cylinder,
providing uplift-lowering of the plough, is connected to the section No3.
To operate in an automatic mode it is required to record two programs:
Program No1 provides automatic implementation of the following operations:
- plough uplift from its working position;
- decrease of plough width to a min. one;
- plough overturn into the working position (from left to right);
- increase of plough width to a required one;
- plough lowering into the working position.
To record the program No1 it is required to do the following:
- actuate the OPU of the HLL, pressing the button 1 (figure 4.2.3);
ATTENTION: BEFORE RECORDING THE PROGRAM NO1 IT IS REQUIRED TO
SET THE PLOUGH INTO A CERTAIN CONDITION IN A MANUAL MODE (THE PLOUGH
SHALL BE TURNED TO THE LEFT INTO ITS EXTREME POSITION, SET A REQUIRED
WIDTH, LOWER THE PLOUGH INTO THE WORKING POSITION)!
- press and hold the button 4 (program No1). After two seconds the OPU of the HLL
produces an acoustic signal, turns on the indicator 5 in the mode of fast blinking and
passes into the programming mode (storing manipulations made with the joystick);
- press the buttons 13, 14, 15 to select sections No3, No2, No1 of the hydraulic dis-
tributor EHS, respectively. The annunciators 10 indicating uplift and lowering of these sec-
tions shall simultaneously turn on in the mode of slow blinking;
