Parameter Settings for Control Unit KRONOS 20
The software for the HEINZMANN digital controllers conceived so that parametrizing can be
done either by the engine manufacturer or by the final customer if the necessary instruments
(communications tool) are available. Only a few basic parameters are pre-set in the
HEINZMANN factory. This means that the digital governor usually gets its definitive set of
data from a source external to HEINZMANN.
An exception is made for control units delivered in greater numbers. If HEINZMANN has
been provided in advance with a definitive set of data, this data can be trasferred to the units
in the factory.
As a principle, initial programming should always be conducted by experienced personnel and
must be checked before first commissioning the engine.
How parameter are adjusted and what meaning they have is explained in detail in the manual
"Basic information 2000".
The following sections describe the possibilities of parametrizing the control unit:
7.1
Parametrization with the Hand Held Programmer 3
All parametrization can be done by means of the hand held programmer ‘Programmer 3’.
This handy device is particularly suited for development and series calibration as well as
for servicing. This unit needs no external power supply.
7.2
Parametrization with the PC / Laptop
Parametrization can also be conducted using a PC and the comfortable HEINZMANN
communication software DcDesk 2000. As compared with the hand held programmer, it
offers the great advantage of having various curves graphically represented on the screen
and being at the same time able to introduce changes as well as of having time diagrams
displayed without an oscilloscope when commissioning the control unit on the engine. Fur-
thermore, the PC offers a better overview as the PC programme has a menu structure and
allows to have several parameters continuously displayed.
Besides, the PC programme permits to save and download the operational data to and from
data mediums. Additional there is the following usefull application:
Once parameterization has been completed for a specific engine type and its application,
the data set can be stored to disk. For future applications of similar type, the data sets
can be downloaded and re-used with the new control units.
