- pilot lamp to indicate low level of coolant 16 get activated when the coolant level
falls below the allowable threshold.
ATTENTION: WHEN THE TRACTOR ON-BOARD SUPPLY VOLTAGE GOES UP
ABOVE 19V THE INTEGRATED INDICATOR FULLY GOES OUT AND RECOVERES
WHEN THE ON-BOARD VOLTAGE FALLS BELOW 17V!
ATTENTION: PILOT SIGNALLING LAMS ARE ACTIVATED AND DEACTIVATED
SYNCHRONOUSLY WITH CHANGING THE STATE OF SYSTEM SENSORS!
2.7.4 Description of testing performance of the integrated indicator
Each time the power supply is on, performance testing of needle pointers and scale
elements of the rear PTO indicator is carried out in the integrated indicator. Herewith the
indicator needle pointers move away from zero marks for one second (or the pointers flut-
ter for not more than one second on indicator zero marks) and also both annunciators of
the rear PTO scale range 6 and 10 get actuated (figure 2.7.1) as well as all segments of
the rear PTO scale.
2.8 Information display
2.8.1 General information
The information display 21 (figure 2.1.1) is designed to display engine actual pa-
rameters and indication of the engine electronic control system (EECS) faults, including
the system of selective catalytic reduction.
When the key of starter and instrument switch is set into "I" position (the instruments
are on) (figure 2.2.2) supply voltage is delivered to the engine electronic control system.
After the supply voltage is delivered the EECS constantly performs self-testing. If there are
no errors in the EECS operation, the information display functions in a working mode – it
displays actual parameters of engine and SCR operation.
When the error is defined, the information display produces an acoustic signal and a
rhombic flashing window with an exclamation marks appears on the screen, also a fault
testing annunciator lights up or flashes on the engine control panel 34 (figure 2.1.1). After
pushing any of five buttons of the information display a brief description of identified errors
appears on the screen (error code identification and its description). Interpretation of error
codes as well as recommended actions to be taken to eliminate the identified faults are
given in the engine operation book attached to your tractor.
ATTENTION: THE ERRORS IDENTIFIED ARE TO BE ELIMINATED! TO ELIMATE
THE ERRORS CONTACT YOUR DEALER!
2.8.2 Adjustment of brightness and sharpness of the information display
To enter the mode of adjustment of screen brightness and sharpness 7 (figure
2.8.2) press button 5. In the screen lower part images of buttons are given. Pressing but-
ton 1 decreases brightness, pressing button 2 increases brightness, pressing button 3 de-
creases sharpness, pressing button 4 increases sharpness, and pressing buttons 1,2,3,4
simultaneously adjusts to an average value of sharpness and max. brightness. Repeated
pressing button 5 exits the mode of brightness and sharpness adjustment.
