Light indicators of the combined indicator
ATTENTION! The light indicators are switched on and off synchronously with the
change of state of the system sensors.
a) 5 – light indicator of the high beam of the headlights. It lights up when the high
beam of the headlights is on.
b)
6, 7 – indicators o switching on the turn indicators of the tractor and trailer. It oper-
ates in the blinking mode when the signal of the right or left turn is switched on by
means of the multi-function control stalk 11 (Figure 2.10) or when the fault signalling is
ON.
c)
8 – light indicator of the parking brake application. The “Parking brake”
( Стояночный тормоз ) indicator blinks at the frequency of 1 Hz when the parking brake
application sensor is on;
d) 9 – light indicator of the overvoltage in the on-board power supply system. It lights
up when the voltage of the on-board power supply system of the tractor exceeds 19 V
and goes out when the power supply voltage level drops down to 17 V;
In this case the CI is fully de-energized and restores its serviceability when the
voltage drops down to the rated value of the on-board power supply system.
e) 10 – light indicator of the low coolant level. It lights up when the coolant level in the
expansion bottle drops below 20% from the total level.
Description of the checking the functioning of the instruments
Each time the combined indicator is energized, the pointer indicators and elements of
the PTO indicator scale elements are tested. When it is done, the pointers of the indica-
tors deflect from the initiate marks over the following first quantized marks of the scales
(over “5” for speed and “10” for rpm) and all the segments and designations “540” and
“1000” of the PTO scale light up.
Programming board of the combined indicator
The programming board makes it possible to per-
form the manual programming of the combined in-
dicator by means of the “Para meter” (Параметр)
and “Value” (Значение) buttons and to modify the
mode of display of the parameters to be shown on
the LCD.
Note: The diagnostic connector ХР1 located on the
front panel of the control board makes it possible to
perform the automatic programming (reprogram-
ming) of the CI by means of a special instrument (if
provided). Should such an instrument be unavailable, the programming shall be per-
formed by means of the above buttons. On the BELARUS- 1523/1523В/1523.3/1523В.3
tractors, the ХР1 connector is not enabled .
