Parameterization
This type of parameterization is performed by the engine manufacturer during the final
bench tests of the engine. By this procedure, the control is tuned to engine
requirements and to ordering specifications.

Saving Data
On principle, the above mentioned communication programmes and devices will modify
parameters only in the volatile memory of the control unit. Although the control unit will
immediately operate using the new values these modifications will get lost as soon as the
the voltage supply is switched off. In order to permanently save the parameter adjustments
in the control unit a storing command must be given. To execute this command DcDesk
2000 uses the function key F6, whereas the Hand Programmers use the key or menu item
“Save Parameter”, and it is this operation that is meant whenever it is required in this
manual that the parameters be saved.

DcDesk 2000
The HEINZMANN PC programme DcDesk 2000 serves for adjustment and transmission
of operating data for all digital HEINZMANN systems, and, in particular, for the
PRIAMOS and HELENOS systems. Designed as a Windows programme, it offers all
numerical and graphical features required for testing, initial commissioning and servicing,
and helps with preparing the respective documentation.
DcDesk 2000 also allows to produce hard copy printouts of its screens and of its data
records. The data is recorded in a standard text format for further processing and for
incorporation into reports, etc.
The data set of any connected control unit can be processed, and, at the same time, the
responses to parameter changes can be observed. Even without a control unit connected, it
will be possible to process a parameter set and evaluate the recorded data. Any parameter
set generated that way can later on be downloaded to the control unit.
Any adjustment can be made by directly accessing the respective parameter numbers.
There exist, however, additional windows to simplify adjustment of specific functions and,
particularly, parameterization of characteristics and maps.
Current measurements are displayed numerically and/or graphically. In a separate window,
up to ten freely selectable measuring values can simultaneously be displayed as functions
of time. There is a further window that permits to have nine measurements represented in
dependence of a tenth. All of these records can be logged to be evaluated later on and
eventually printed out.
