Error signalling
Indication of the limitation of the engine power and engine revolutions
Errors arising during tractor operation are indicated by
switching the corresponding signal lamp, acoustic signal
and error message in the instrument panel display.
If the error is indicated, the signal lamp still glows, even
though the display is switched to the next display.
If the error is not eliminated or the indicated state has not
returned to a normal state:
the corresponding signal lamp glows
when the tractor is switched off, the key in the switch box
is moved to position I and then the engine is started, the
corresponding signal lamp is switched on again and the
error message runs through the display.
1 - The signal lamp of a serious defect of the system (red).
2 - The signal lamp of a less serious defect of the system
(orange).
3 - Operational protection signal lamp (blue).

If there is a serious error in control or auxiliary systems of
the engine, SCR system or if the level of urea in the tank
is low, the reaction of the system is reduced engine power
output and revolutions.
According to the error type, so-called one-stage or two-
stage reduction of engine output indicated by glow of the
signal lamps (1), (2), (3) and (4) is performed.
