Figure 2.9.1 – Integrated electronic panel
Annunciator of water presence in the fuel filter 1 (figure 2.9.1) lights up when concentration
of water in coarse fuel filter exceeds the allowable threshold. In case the annunciator 1 goes off it is
required to drain sediment from the coarse filter.
Annunciator of emergency oil pressure in the engine 2 lights up when oil pressure in the en-
gine drops below the allowable threshold.
If the annunciator 2 is on with the engine running, immediately stop the engine and
eliminate the fault!
With buttons 6 and 7 foot fuel-feed pedal either on forward or on reverse motion is cho-
sen. The pedal chosen is remembered and upon the next power supply switch the latest state
will be chosen. Information on the pedal chosen is displayed on the annunciators 5 and 8.
Annunciator of emergency temperature or level of coolant 9 (figure 2.9.1) lights up when the
coolant temperature goes up above the allowable threshold or the coolant level drops below the
allowable threshold.
Indicator of inlet air heating indicates performance of inlet air heater (algorithm of functioning
of the inlet air heater indicator 10 is given in subsection 3.23.2 “Operation principle of inlet air
heater”).
Button to activate testing 11 is designed to invoke active errors from the memory of the
engine electronic control unit by means of light codes, displayed by the annunciator of fault
testing 4. This testing method is alternative to the information monitor 21 (figure 2.1.1). Refer
to the engine operation manual, attached to the tractor, concerning read-out and decoding of
error light codes and concerning recommended actions to be taken to eliminate faults. The
identified faults are to be eliminated. To have the faults eliminated contact your dealer.
Buttons and annunciators 3, 12, 13, 14, 15 (figure 2.9.1) relating to warning of time for main-
tenance, control of fan reverse rotation and control of coolant heater do not currently function on IEP
and stay reserve.
With short pressing any button sound annunciator goes off.
