1.8.2 MENU POINT "ECU SELECTION”
It may be the case that one DEUTZ engine is fitted with one or several ECUs (e.g. the combination of MVS with EMS). How-
ever, SERDIA can only communicate with one ECU.
Exception: It is also possible for the list of errors to be read via EMS, and measured values can be read from the MVS.
You must therefore first select the ECU you require from the menu point 'ECU selection'.
For more details, please see Chapter 2, ECU selection.
1.8.3 MENU POINT "MEASURED VALUES” ("ACTUAL MEASURED VALUES")
Selection and display of measured values is also possible from a list of measured values (including input and output val-
ues).
Displayed measured values that have exceeded an upper or lower value (if applicable) are stored in color.
Only those measuring points that are appropriate to the ECU are displayed in sequence, differentiated by the following:
• read measured values
• read ejectronics measured values
• read mcorter data (EMS speda menu)
displayed by:
• designation
• value
• unit
The measured values are rerreshed after a predefined sensor rate. They can be displayed with the engine shut down as well
as with the engine in operation.
For rnore information, please see Chapter 3. Meas,ed values.
1.8.4 MENU POINT "PARAMETERS"
The wide range of possibilities open to you with DEUIZ ECUs means that very specit\c programrning IS requireci in ac-
cordance with each indivtdual applicauon case Changes to parametrization beconne necessary if:
• custonner requiremenis
• abaptation to locai requirements
• replacement installation
The pararneters can only be changed with SERDIA!
This menu point also does away with the neecl br screwdriver setting, as is necessary with analog ECUs. Individuai pa-
rameters (such as dynamic go~ernor characteristics) can uso LE changed 'nithin predefsned limits. Parametrization is car-
ried out in two separate screens, one for configuration and one for calibration. Access to the flelds in the various screens
is controlled from the user level. Fields for which no access authorization exists are not displayed. It is even possible to
swap over entire blocks or parameters from this function field in order to create variants.
For more information. please see Chapter 4, Parameters..
1.8.5 MENU POINT "ECU SELECTION”
The error messages stored in the ECUs can be read from this menu point.
Error messages refer solely to the electrical parts of the engine system, such as the cable harness and the measured value
sensors.
An error message may take the form of: "Broken cable or short-circuit".
Only passive error messages can be cleared, active messages are retained. When the error is corrected, active error mes-
sages are changed into passive error messages. The error message will be retained even if you disconnect the battery/
power supply.
Error messages display information on
•
error location
• type of error
• total number of errors (at the error locations)
• frequency
• error status (active / passive)
• environment data at the time the error was detected.
