The handle 7 has four positions:
а
) middle position – disengaged;
b) upper position – uplift;
c) lower position – lowering (in operation – automatic control);
d) moving the handle downward (nonfixed) from “
в
” position – implement penetra-
tion (herewith the automatic control is off);
During RLL lowering or penetration the annunciator 6 turns on, and during uplifting
– the annunciator 5 turns on.
The
system automatically limits a frequency of correction under draft control to an
average of 2 Hz. In case of intensive heating of oil in hydraulic system it is necessary to
reduce frequency of correction by moving the handle 2 towards the position method of
control and the handle 1 towards “turtle”. In a case of raising (“working out”) of the agricul-
tural implement when moving over consolidated soil or ruts, deepen the implement by
pressing the handle 7 downwards. After releasing the handle 7 will come back to its fixed
position of "lowering". Thus the agricultural implement returns to the mode of the depth,
set up before by the handle 4. The implement is raised by moving the handle 7 into the
upper position.
When height adjustment of RLL is carried out during operation, the unnunciators 5
and 6 turn on.
ATTENTION: IN ORDER TO AVOID HLL PUMP FAILURE, IT IS FORBIDDEN TO
OPERATE THE TRACTOR IF ANNUNCIATOR 5 DOES NOT GO OUT AFTER THE IM-
PLEMENT WAS UPLIFTED.
ATTENTION: AT THE EMERGENCY STOP OF THE TRACTOR, IN ORDER TO
AVOID FURTHER PENETRATION OF THE AGRICULTURAL IMPLEMENT, SHIFT THE
HANDLE 7 INTO POSITION ”DISENGAGED”. AFTER STARTING TO MOVE SHIFT THE
HANDLE INTO POSITION “LOWERING” – THE IMPLEMENT WILL PENETRATE TO
DEPTH, SET UP BEFORE!
It Is required to know the following operation peculiarities of RLL control system:
- after the engine was started the diagnostics annunciator 9 lights up, indicating
workability and blocking of the control system;
- to unblock the system it is necessary to set the handle 7 into operating condition for
one time (uplift or lowering) and return to the position “disengaged”. Hereby the diagnostics
annunciator 9 goes out.
- after the system is unblocked during first engagement automatic speed limitation
for the RLL uplift and lowering is provided for safety's sake. Moving the handle 7 into posi-
tion “Disengaged” and then into position “Uplift” or “Lowering” removes the speed limita-
tion.
Besides the functions described above the RLL electronic control system has a
mode “dampening” – suppression of oscillations of the agricultural implement in a transport
mode.
Turn on the “dampening” mode in the following order:
- set the handle 7 into “uplift” position
рукоятку
7 – herewith the RLL lifts up to the
top extreme position and gets automatically deactivated;
- push the button “dampening” 10 – hereby the RLL moves form the top extreme
position down by 3% of the full RLL stroke and the annunciator of “dampening” activation
11 turns on;
- then to prevent accidental shifting of the handle 7 during transportation move the
blocking retainer 8 to the rotation axis of the handle 7. Hereby the handle 7 will be me-
chanically blocked in the upper position (“uplift”).
