3.23.1 General information
The electric circuit diagramm of tractors BELARUS-3522.5 is shown in annex D.
3.23.2 Operation principle of inlet air heater
The inlet air heater (IAH) is intended for air heating at inlet in compression chamber
at start of cold engine.
The IAH is not active, if the temperature of the engine is more than +5°C.
Switching in of IAH occurs automatically when the starter switch key is shifted from
position “0” (off) in position “I” (Instruments ON). Herewith on right side panel in integrated
electronic panel (IEP) lights up indicator 10 of IAH operation (figure 2.9.1). The action pe-
riod of IAH depend on engine temperature. The engine should be started after indicator 10
goes out. After engine start the inlet air heater is active for a shot time and then switches
out automatically.
The motor control group control also IAH and its functioning. In case of fault begin-
ning in IAH operation on information display appears corresponding message.
TRACTOR OPERATION IS FORBIDDEN TILL ALL FAILURES IN AIR INLET
HEATER SYSTEM ARE FOUND AND CORRECTED, BECAUSE THE FAILURE CAN
LEAD TO BURN-OUT OF HEATING ELEMENT OF IAH FLANGE AND TO BATTERY
DISCHARGE!
3.23.3 Programming console of integrated indicator
3.23.3.1 Control panel of integrated indicator
Figure 3.23.3 – Control panel of itegrated indicator
The control panel 16 (figure 2.1.1) makes it possible to perform the manual programming of
the indicator by means of the “Parameter” and “Value” buttons (figure 3.23.3) and to change
the mode of the parameters to be shown on the LCD.
The diagnostic connector ХР1 located on the front surface of the control panel makes it
possible to perform the automatic programming (reprogramming) of the integrated indicator (II)
by means of a special device (if provided). Should such an device be unavailable, the pro-
gramming shall be performed by means of the abovementioned buttons. On the BELARUS-
3522.5 tractors, the ХР1 connector is not enabled.
3.23.3.2 Algorithm of Integrated Indicator programming
To choose a fixed value of a parameter of the Integrated Indicator programming the fol-
lowing shall be done:
- upon first pushing the button “Parameter” (figure 3.23.3) the multifunctional Indica-
tor 17 (figure 2.7.1) transits into the mode of viewing a programmable parameter
and its numeric value . Upon repeated pushings the button “Parameter” a cyclic
change of parameters takes place;
