Cab Ventilation; Instrument Board - Belarus 3522.5 Operator's Manual

2.4.3 Cab ventilation

During the conditioner operation in the cooling and heating modes the cab ventila-
tion is executed simultaneously. To make the conditioner operate only in the ventilation
mode it is necessary to close the heater control valve, set the switch 2 (figure 2.4.1.) in po-
sition "0" and the switch 1 in any of three marked positions.

2.5 Instrument board

Variant 1
The instrument board 13 (figure 2.1.1) includes six gauges with five signal lamps as
shown in figure 2.5.1.
1 – gauge to indicate oil pressure in the transmission system; 2 – signal lamp of
emergency air pressure in the pneumatic system; 3 – gauge to indicate air pressure in the
pneumatic system; 4 – pilot lamp of voltage gauge; 5 – voltage gauge; 6 – signal lamp of
reserve fuel volume in the tank; 7 – gauge to indicate fuel volume in the tank; 8 – signal
lamp of emergency temperature of engine coolant; 9 – gauge to indicate temperature of
engine coolant; 10 – gauge to indicate oil pressure in the engine lubrication system; 11 –
signal lamp of emergency oil pressure in the engine lubrication system;
2.5.1 The gauge of oil pressure in the transmission hydraulic system 1 (figure 2.5.1)
indicates oil pressure in the hydraulic system of friction clutches control in tractor transmis-
sion.
The scale of oil pressure gauge has three zones:
- working — from 800 to 1500 kPa (green color);
ATTENTION: FOR TRACTOR "BELARUS-3522.5" THE WORKING ZONE IS
CONSIDERED A SCALE SECTION FROM 1300 TO 1500 kPa. WITH MINIMUM STABLE
ENGINE SPEED OIL PRESSURE IN THE TRANSMISSION HYDRAULIC SYSTEM
SHALL BE NOT LESS THAN 1000 kPa!
- emergency (two) — from 0 to 800 kPa and from 1500 to 1800 kPa (red color).
ATTENTION: OPERATING TRACTOR WITH OIL PRESSURE IN THE TRANS-
MISSION BELOW 1300 KPA AT ENGINE SPEED NOT LESS THAN 1400 RPM IS
FORBIDDEN!
2.5.2 The scale of the gauge of oil pressure in the pneumatic system has three
zones:
- working – from 500 to 800 kPa (green color);
- emergency (two) — from 0 to 500 kPa and from 800 to 1000 kPa (red color).
A signal lamp 2 (red color) is built in the gauge scale which lights up when the pres-
sure in the pneumatic system drops below 500 kPa.
