5.1 Fault messages - Key

The fault messages are applicable to 8V, 12V, 16V and 20V engines.

Explanation of the abbreviations used

The following abbreviations are used in the texts for the fault messages:

Abbreviation

Meaning

DL <number>

Default Lost: The device with designation <number> has lost its connec-
tion to the default CAN bus.

RL <number>

Redundant Lost: The device with designation <number> has lost its con-
nection to the redundant CAN bus.

SD <sensor designation>

Sensor defect: The sensor with the designation <sensor designation> is
not sending an analyzable signal.

MD

Missing Data: Data is missing from a measuring point.

AL

Alarm: Alarm message

SS

Safety System: The safety system has reacted in some way.

TD

Transmitter Deviation: Two sensors that record the measured values for
the same medium are sending different measured values.

HI

High: The first limit value has been exceeded.

HIHI

High High: The second limit value has been exceeded.

LO

Low: The first limit value has not been attained.

LOLO

Low Low: The second limit value has not been attained.

MG

Message: General message

SE

System Error: Warning due to node failure on the default field bus.

PB

Push Button: Status indication due to activation of certain control keys.

AKR

Anti Knock Control GET

Important information about fault messages from the engine governor/engine
monitoring

Fault messages from the engine governor are represented in the fault code list (→ Page 95).
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 man-
ufacturer).
A prerequisite for performing the measures to rectify faults is corresponding qualification/training at
MTU.
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.
