2.5.3 The voltage gauge 5 (figure 2.5.1) indicates accumulator batteries voltage with
the engine stopped when the key of starter and instruments switch (figure 2.2.2) is set in
position “I”. With the engine running the voltage gauge indicates voltage on generator ter-
minals. A pilot lamp 4 is built in the scale of voltage gauge – on tractors “BELARUS-
3522.5” it is not used.
The states of the power supply system depending on the position of the gauge
pointer on the scale are given in table 2.1.

ATTENTION: IF THE VOLTAGE GAUGE INDICATES ABSENSE OF AB CHARGE,
CHECK THE STATE AND TENSION OF THE GENERATOR DRIVE BELT!
2.5.4 The scale of the gauge indicating fuel volume in the tank 7 has three divisions
“0-1/4-1/2-3/4-1”. A signal lamp 6 (orange color) is built in the gauge scale, which lights up
when fuel volume in the tank drops below 1/8 of the total tank volume.
ATTENTION: DO NOT LET THE TANK BECOME EMPTY (THE GAUGE POINTER IS
IN THE ZONE OF ORANGE COLOR)!
2.5.5 The gauge of engine coolant temperature 9 reads data from the engine control
unit (ECU). The gauge scale has three zones:
- working – from 70 to 105 °
С
(green color);
- informational – from 40 to 70 °
С
(yellow color);
- emergency – from 105 to 120 °
С
(red color);
An emergency temperature lamp (red color) 8 is built in the scale, which operates in
two modes:
а
) gets actuated and operates in a flashing mode with coolant values from 109 up to
and including 112 °
С
.
б
) glows in a continuous mode with coolant temperature values from 113 °
С
and
higher.
2.5.6 The oil pressure gauge in the engine lubricating system 10 reads data from the
engine control unit (ECU). The gauge scale has three zones:
- working – from 100 to 500 kPa (green color);
- emergency (two) – 0 to 100 kPa and from 500 to 600 kPa (red color).
A signal lamp of emergency oil pressure drop 11 (red color) is built in the gauge
scale, which lights up when the pressure drops below 100 kPa.
ATTENTION: WHEN THE COLD ENGINE IS STARTED THE PRESSURE CAN BE
600 kPa and HIGHER!
ATTENTION: IF THE EMERGENCY PRESSURE LAMP IS ON WITH THE ENGINE
RUNNING, IMMEDIATELY STOP THE ENGINE AND ELIMINATE THE FAILURE!
