Performing operations on control of implements connected to the hydraulic distribu-
tor EHS sections, the OPU of the HLL allows to remember and reproduce operations, car-
ried out before. The OPU of the HLL has a possibility to remember three different joystick
manipulations.
To control the hydraulic distributor EHS sections in the automatic mode it is re-
quired to turn on the OPU of the HLL by pushing the button 1 (figure 2.16.6). After check of
elements of the OPU of the HLL for performance it is possible to get down to work.
To record the sequence of operations performed it is required to press a button of the
program selected for programming 2 on the board of OPU of the HLL and hold it depressed.
After two seconds the OPU of the HLL produces a short acoustic signal, turns on the annun-
ciator 3 of the corresponding program in the mode of quick flashes and goes into the pro-
gramming mode – remembering of manipulations performed by the joystick. Herewith a pro-
gram, recorded to this button before, is erased.
On entering the programming mode it is required to select the hydraulic distributor
EHS sections to be controlled, by means of pressing the corresponding button switches 9,
after this the OPU of the HHL produces an acoustic signal and turns on the annunciators
“uplift” and “lowering” 4 and 8 of the hydraulic distributor EHS selected sections in the
mode of slow flashes.
Then with joystick manipulations in accordance with clauses 2.16.2.2 and 2.16.2.3
the annunciators “uplift” 4 and “lowering” 8 display performance of the corresponding op-
erations without flashes, the annunciator 5 displays a number the hydraulic distributor EHS
section to be controlled, the indicator 6 displays oil flow value within the section to be con-
trolled. In the “floating” mode the indicator 6 displays symbols “FL”.
The OPU of the HLL remembers all joystick manipulations. Repeated pressing the
corresponding button switch 9 of the selected section results in finish of storing joystick
manipulations for this section. After this the OPU of the HLL produces a short signal and
annunciators, displaying state of the hydraulic distributor EHS sections, light up on the
board.
To stop recording the selected program, first it is required to press buttons 9 of the
sections which are in the mode of program recording. Then it is necessary to push the but-
ton 2 of the program recorded for short time. After this the OPU of the HLL produces a
short acoustic signal and the corresponding annunciator 3 of the recorded program lights
up on the board. With repeated short-time pressing the button 2 of the recorded program a
short acoustic signal is produced, the corresponding annunciator 3 goes out, the OPU of
the HLL deactivates the program recording mode and goes into the mode of joystick con-
trol (manual mode).
ATTENTION: MAX. POSSIBLE DURATION OF EACH PROGRAM RECORD IS
NOT ABOVE 200 SECONDS!
ATTENTION: PROGRAM SHALL BE RECORDED AND REPRODUCED WITH
THE SAME ENGINE SPEED!
With the beginning of the other program recording the annunciator of the previously acti-
vated program goes out. Recording other programs is carried out by analogy.
After the program is recorded it is possible to start its automatic implementation.
2.16.3.3.2 Automatic control of the hydraulic distributor EHS sections under the previ-
ously recorded programs is carried out with the OPU of the HLL activated. The OPU of the
HLL performs commands according to one of the three algorithms programmed by the opera-
tor. Implementation the program recorded is started with pressing a corresponding button 2.
Hereby the annunciator 3 of the selected program turns on in the mode of slow flashes on the
board. If before the other program was active, then it gets deactivated. After implementation
of the active part of the program the annunciator burns continuously, the annunciators 4, 5, 6,
8 of the hydraulic distributor EHS sections display their state.
