The mode of “RADL automatic control” is disengaged by repeated pressing the button
13 “AUTO” or by pressing and releasing the button of RADL positive engagement 22. Herewith
the annunciators 12 and 21 will go out.
If there is a necessity of RADL positive engagement for short time, irrespective of
tractor speed and front wheels turning angle, it is required to push button 22 and hold it
pressed. RADL remains engaged during holding the button 22 pressed. Simultaneously
the annunciators 21 and 23 go off. On releasing the button 22 the RADL returns to its ini-
tial (disengaged) state and the annunciators 21, 23 go out.
To transfer from the automatic mode of RADL engagement to the positive mode it is
necessary to press the button 22 at once and hold it pressed.
IT IS FORBIDDEN TO OPERATE THE TRACTOR WITH RADL ENGAGED WHEN
THE SPEED OF MOVEMENT IS ABOVE 13 KM/H!
IT IS FORBIDDEN TO OPERATE THE TRACTOR ON TRANSPORT ON ROADS
WITH HARD SURFACE WITH RADL CONSTANTLY ENGAGED!
2.13.5.7 Annunciation of emergency states of transmission and HLL hydraulic sys-
tems, diagnostics of emergency voltage in on-board power system
Annunciator of impurity of a twinned filter of transmission hydraulic system 16 (fig-
ure 2.13.4) lights up when the twinned filter is clogged to a large extent. It is required to
replace the filtering element of the twinned filter of the transmission hydraulic system.
Annunciator of HLL pump filter impurity 15 lights up (and operates in the mode of
continuous glowing) when the HLL pump filter is clogged to a large extent. It is required to
replace the HLL pump filter.
ATTENTION: IT IS POSSIBLE THAT THE ANNUNCIATORS MAY GET ACTU-
ATED FOR SHORT TIME WHEN OIL IN TRANSMISSION AND HLL HYDRAULIC SYS-
TEMS IS COLD, THIS IS NOT A FAILURE!
Annunciator of emergency oil level in HLL 14 lights up when oil level in the HLL tank
drops below the permitted value.
Annunciator of emergency oil temperature in HLL 19 lights up when oil temperature
in HLL tank increases above the permitted value. Besides, when oil temperature in HLL
pump increases above the permitted value, the annunciator 15 gets actuated and operates
in a flashing mode.
In case the emergency annunciators of hydraulic systems 14 and 19 go off it is re-
quired to stop work, find out and eliminate causes for the emergency condition in order to
prevent breakdown and failures of hydraulic system units.
ATTENTION: IF THE SUPPLY VOLTAGE GOES UP ABOVE 18V THE ANNUN-
CIATOR OF EMERGENCY SUPPLY VOLTAGE LIGHTS UP, THE CECS GETS FULLY
DEACTIVATED (CONTROL OF ALL WIRES AND GEARBOX IS STOPPED) AND RE-
COVERS THE WORKABILITY WHEN THE VOLTAGE DROPS BELOW 17V!
IF THE SUPPLY VOLTAGE DROPS BELOW 9V THE CECS GETS FULLY DEAC-
TIVATED (CONTROL OF ALL WIRES AND GEARBOX IS STOPPED) AND RECOVERS
THE WORKABILITY WHEN THE VOLTAGE GOES UP ABOVE 9V!
When any of the annunciators 14, 15, 16, 19 or 20 gets activated an acoustic signal
(buzzer) goes off. It is possible to deactivate the acoustic signal temporary, for this press
the button 18 shortly, hereby the annunciator of buzzer activation, which is located to the
left of the button 18, turns on and off. It shall be taken into account that in future when the
CECS is activated and the emergency sensors go off, the acoustic annunciator will stay on
until the corresponding fault is eliminated and the filtering element is replaced.
