Each of the abovestated fault messages is displayed in priority on the information
field 2 of the multifunctional display irrespective of the information currently displayed. With
sequential pushing the “Mode” button of the integrated indicator control module the mes-
sages shall be listed in turn. After the last message has been viewed and the “Mode” but-
ton has been repeatedly pressed the multifunctional display changes into displaying the
cyclic mode of the operating parameters specified before.
The fault messages are displayed on the LCD-screen every time the device is actu-
ated until the cause is eliminated.
When the integrated indicator is powered-on the multifunctional display shows in-
formation in the indication mode which has been chosen before the moment of powering
off the integrated indicator.
2.7.3 Pilot lamps of the integrated indicator
The operating principle of pilot lamps on the integrated indicator is as follows:
- pilot lamp to indicate switching on the road lights upper beam 11 (figure 2.7.1)
lights up when switching on the upper beam;
- indicators of tractor turns and trailer turns 13 and 12 operate in a flashing mode
when actuated with the underwheel multifunctional switch 2 (figure 2.2.1) or when the
emergency button 4 is pushed in;
- pilot lamp to indicate the parking brake is enabled 14 (figure 2.7.1) operates in a
flashing mode with 1 Hz frequency when the parking brake sensor goes off;
- pilot lamp to indicate increased on-board voltage 15 gets activated when the trac-
tor on-board supply voltage goes up above 19V and goes out when the voltage falls below
17V;
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 the integrated indicator performance
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 Steering
2.8.1 General information
BELARUS-1822.3/1822 .3/2022.3/2022 .3 tractors are equipped with hydrostatic
steering control (HSC). When the engine is stopped the HSC feed pump, driven by the en-
gine crankshaft, does not feed the hydraulic system of the HSC and it is automatically
shifted to a manual mode, which requires application of a greater effort on the steering
wheel in order to turn the tractor.
