Handle 11 has four positions:
а
) middle position – off;
b) upper position – uplift;
c) lower position – lowering (in operation – automatic control);
d) moving the handle downward (nonfixed) from “
в
” position – implement penetration (in
this case the automatic control is off).
During RLL lowering or penetration, annunciator 9 turns on and during uplifting –
annunciator 5 turns on.
The system automatically limits frequency of correction under draft control to an average
of 2 Hz. In case of intensive heating of oil in the hydraulic system, it is necessary to reduce
frequency of correction by moving handle 8 towards the position method of control and
handle 7 towards the “turtle”. In case of raising (“working out”) of the agricultural implement
when moving over consolidated soil or ruts, deepen the implement by pressing handle 11
downwards. After releasing handle 11 it comes back to its fixed position of "lowering". In
this case the agricultural implement returns to the mode of the depth set before with han-
dle 4. The implement is raised by moving handle 11 into upper position.
When height adjustment of RLL is carried out during operation, annunciators 10 or 9 turn
on.
ATTENTION: IN ORDER TO AVOID HLL PUMP FAILURE, TRACTOR OPERATION IS
FORBIDDEN IF ANNUNCIATOR 10 (FIGURE 2.17.1) DOES NOT GO OUT AFTER THE
IMPLEMENT UPLIFTING!
ATTENTION: AT THE EMERGENCY STOP OF THE TRACTOR, IN ORDER TO AVOID
FURTHER PENETRATION OF THE AGRICULTURAL IMPLEMENT, SHIFT CONTROL
HANDLE 11 (FIGURE 2.17.1) INTO THE POSITION ”OFF”. AFTER STARTING THE
MOVEMENT, SHIFT THE HANDLE INTO THE POSITION “LOWERING” – THE IMPLE-
MENT WILL PENETRATE TO THE DEPTH SET BEFORE!
It Is required to know the following operation peculiarities of RLL control system:
- after the engine start, diagnostics annunciator 5 lights up, indicating the control system
workability and blocking;
- to unblock the system, set handle 11 into the operating position for one time (uplift or
lowering). In this case diagnostics annunciator 5 goes out.
- after unblocking the system during the first activation, automatic speed limitation for RLL
uplift and lowering is provided for safety reasons. Setting handle 11 into the position “Off”
and then into the position “Uplift” or “Lowering” removes the speed limitation.
Beside 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 handle 11 into the “uplift” position – in this case RLL lifts to the extreme upper posi-
tion and automatically gets deactivated;
- press button “dampening” 2 – in this case RLL moves form the extreme upper po-
sition down by 3% of full RLL stroke and annunciator of “dampening” activation 3 turns on;
- then to prevent accidental shifting of handle 11 during transportation, move block-
ing retainer 1 to the rotation axis of handle 11. In this case handle 11 gets mechanically
blocked in the upper position (“uplift”).
To turn off the “dampening” mode, press button 2. The annunciator of “dampening” activa-
tion goes out, and RLL returns to the upper position. Move retainer 1 to its initial position.
