Error Signalling; Indication Of The Limitation Of The Engine Power And Engine Revolutions; Signalling Errors In The System Of Additional Treatment Of Exhaust Gases - Zetor CRYSTAL HD 150 Operator's Manual

Error signalling

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).

Indication of the limitation of the engine power and engine revolutions

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) and (2) is performed.
stage 1 Reduction of engine power
by 25 %
stage 2 Reduction of engine power
by 50% Reduction of engine
revolutions to 1,250 rpm

Signalling errors in the system of additional treatment of exhaust gases

The label with a short description of indication of errors in the system of additional treatment of exhaust
gases and subsequent activities of operators is located in the right bottom corner of the windshield (A).
On the label (B) in the left part there is a combination of signal lamps glowing or flashing on the instrument
panel indicated using pictograms including their colours and the pictogram of the sounding acoustic warning
signal.In the right part of the label a required reaction of the tractor operator is described.
1. Add urea.
2. Add urea.The engine power will be limited.
3. Add urea.Engine revolutions will be minimised.
4. Increase the engine load or contact service.The engine power will be limited.
5. Contact service.The engine power will be limited and engine revolutions will be minimised.
