AIR SUSPENSION REMOTE-CONTROL CONSOLE
Air suspension electronic control system fulfills
the following functions:
1. If there is sufficient pressure in receiver and
hand brake is released, the system automatically settles
the suspension into position in which it was at the mo-
ment of previous power OFF.
2. The system allows to adjust the height of plat-
form and to record any two heights and to set any of
them, if needed, using the remote-control console;
3. The system maintains the earlier settled height
automatically and locks the suspension during retardation.
At speed more than 30 km/h, the system sets the
«transport» position of height automatically, at speed
more than 60 km/h – the second «transport» position (to
decrease the height of gravity center and to increase the
truck stability).
4. It provides built-in self-diagnostics in process of
traveling. If any fault is detected, the pilot lamp of air
suspension fault lightens on the instrument panel
.
Air suspension electronic control system does not
require special maintenance except control inspection of
operability (in the service center).

of remote-control console arranged to the left of driver’s
seat.

the button 1, with this the lamp 2 comes on (see Fig. Air
suspension remote-control console ). The console is OFF
if you depress the button 1 again, the lamp dies out.

form raising/ lowering switches, correspondingly.
