3.4.2 Fault dlsplays
Faults in the overall MDEC system are indicated at the devices of the MCS-5 sub-system as follows:
• FauH code numbers (generated inside Engine Control Unít ECU) on a 4-figure 7 -segment display in PIM A511
• Plain text fauH display in the form of text messages on display DIS (option)
Rect'fy faults as saon as poaslble aven if they would appear to be insignificant in order to avoid impairing operation of the plant or system failure.
Always check the following points first if a fault occurs when the overall system is switched on:
• Is it a phantom fauH (e.g. because the system is in Local mode)?
• Have all the necessary requirements for the operating procedure, or for the control procedure of a superordinate system, during which the fault occurs been fulfilled?
• Does a fauH message appear on the display in PIM A 511 ? If so, countermeasures can be determined by consulting the appropriate fault code table.
Table
The number of the fauH code on the display is listed in the first column "No." in the table.
The precise text message is listed in the second column "Fault display" in the table. This corresponds with the fault code displayed on the DIS display (oplion).
The message is explained in the third column "Meaning/cause" and the reason for the message is explained.
The fourth calumn "Counteraction" in the table lists measures which can be taken on-site by the operator or other information about how to proceed.
The last two columns indicate which fault can appear for which series.
Malfunctions whieh may be caused by mechanical fauH are referenced to the engine documentation with ". Engine documentation".
". Electronics service" indieates that further testing and rectifieation are a matter for trained service personnel or experienced users with access to the appropriate doeuments (e.g. wiríng diagrams) .
Note: •• Engíne documentatíon" refers to the "Operating instructions for engine series 2000". Part E and PartG.

Replaclng Engine Control Unlt ECU
T-E-G24-0001
Duration: 15m!n Qualification: E1
System componentS/devlces OK?
• Engine Control Unit ECU on tha angine O • New Engine Control Unit ECU O • Suitably programmed memory modulas as necessary (see below) O
Equlpment OK?
• A set of screwdrivers O • A set of Allan wrenches O • Connedor pliers O
Addltional safety notes OK?
• Thare are two memory modules in Engine Control Unit ECU. One contains a data O record which is only valid for the engine for which thls particular ECU Is usad. The other contains data about the system (so-called plant data). It is absolutely vital that these memory modules be transferrad from the old ECU to the new ECU. The engine is not properly controllad If these instructions are ignorad and an incorred data record is used.
• The oparating voltage must be switched off. O
List of actlvitles ID no. OK?
1. Switching off the operating voltage. O 2. Removing the housing of Engine Control Unit ECU from the A-E-G24-QOO1 O
engine. Paga 42
3. Opening the cover on Engina Control Unít ECU. A-P-ECU-0006 O Paga 43
4. Transferring mamory modules in Engine Control Unit ECU. A-E-ECU-0011 O Paga 44
5. Fitting the covar on Engina Control Unit ECU. A-P-ECU-0007 O Page 46
6. Mounting the housing of Engine Control Unít ECU on the A-E-G24-OOO2 O engine. Paga 47
