Adjustment Of The Fixed Flow, Programmed With The Opu Of The Hll; Hydraulic Distributor Ehs Emergency Shut-Down - Belarus 3522.5 Operator's Manual

If during the program implementation you turn the power disconnect switch 1 (figure
2.16.6) of the OPU of the HLL into the disengaged position, the program implementation
will be stopped and further control is possible only with joysticks. After the OPU power
switch-on and repeated pressing of the button 2 the selected program will be started from
the beginning.
When during implementation of the program on the hydraulic distributor EHS sec-
tion control, the hydraulic distributor EHS section is simultaneously controlled with the joy-
stick, then the program implementation will be stopped and the hydraulic distributor EHS
section will be controlled by the joystick. Hereby the annunciators 4, 8 of the hydraulic dis-
tributor section and the annunciators of the active program 3 will operate in a flashing
mode. To continue the program implementation it is needed to press the button switch 2 of
this program.
During the program implementation the hydraulic distributor EHS sections that are
not enabled in this program can be controlled with the joysticks manually. Joystick control
per unprogrammed sections of the hydraulic distributor EHS does not stop the program
implementation.
2.16.3.3.3 Examples of programming operations on the hydraulic distributor EHS
section control
Examples of programming operations on reversible plough and seeder control by
means of the OPU of the HLL are given in subsection 4.2.6 "Examples of programming
operations on the hydraulic distributor EHS section control".

2.16.3.4 Adjustment of the fixed flow, programmed with the OPU of the HLL

After the program implementation and if there is a necessity to adjust a fixed flow
value for one of the sections of the hydraulic distributor in this program it is needed to do
the following:
- choose a required section of the hydraulic distributor EHS with the button switch 9
(figure 2.16.6). On the OPU board the annunciator 5 will display the number of the se-
lected section of the hydraulic distributor, and the indicator of the hydraulic distributor flow
value 6 will display the oil flow;
- change the flow value with the joystick – if the flow value, set up with the joystick,
coincides with the recorded value, the OPU of the HLL produces a short acoustic signal
and further the flow is changed synchronously with the joystick;
- set required flow with the joystick and press the button switch 9 of the selected
section of the hydraulic distributor, after this the changes in the program will take place.

2.16.3.5 Hydraulic distributor EHS emergency shut-down

ATTENTION: FOR EMERGENCY SHUTTING-DOWN OF ALL SECTIONS OF THE
HYDRAULIC DISTRIBUTOR EHS IT IS REQUIRED TO PRESS THE EMERGENCY
"STOP" SWITCH 7 (FIGURE 2.16.6) ON THE OPU BOARD. HEREBY THE POWER
SUPPLY TO THE HYDRAULIC DUSTRIBUTOR IS CUT OFF, CENTRAL VALVES OF
ALL SECTIONS ARE SET INTO NEUTRAL POSITION, OIL SUPPLY TO DRIVES OF
AGRICULTURAL IMPLEMENTS IS STOPPED (THE FLOW REGULATION VALVE
SHUTS DOWN)!
REPEATED PRESSING THE EMERGENCY "STOP" SWITCH ACTIVATES
POWER SUPPLY TO THE HYDRAULIC DISTRIBUTOR EHS AND RESUMES POWER
SUPPLY TO ALL DRIVES OF AGRICULTURAL IMPLEMENTS!
ATTENTION: WHEN OPERATING THE TRACTOR WITHOUT NEED OF USING
THE HYDRAULIC DISTRIBUTOR EHS IT MUST BE TURNED OFF BY MEANS OF
PRESSING THE EMERGENCY "STOP" BUTTON!
