Information pertaining to alarm colors and automatic engine shutdown in the fault code list refer to the
(default) factory settings of the engine governor on delivery. Different system response may be possible
due to changes to the genset control system made by the OEM (see documentation of the genset manu‐
facturer).
Only persons with a corresponding qualification/training at MTU are allowed to carry out the measures
listed below.
Contact Service should troubleshooting as prescribed in the fault code list prove unsuccessful.
Recommended action in case of alarm
Yellow alarm:
The engine can still be operated providing that automatic engine shutdown to protect the engine has not
been configured or is not tripped. Contact Service immediately/start fault rectification.
Red alarm:
Caution, the engine is running at its limits. Shut down manually without further delay if the engine does
not shut itself down immediately after a red alarm is signaled.
