Levels
As it is the Digital Control's primary function to control the operational behaviour of the
engine with regard to speed, power, etc., parameterizing should remain entrusted
exclusively to the engine manufacturer. However, to let also the ultimate customer
participate in the advantages of the Digital Control, the parameters of the HEINZMANN
Digital Control have been classified according to seven levels.
Level 1: Level for the ultimate customer
On this level, it is possible to have the basic operational values (e.g., set
values and current values of speed and injection quantity) and errors
displayed. This level, however, does not allow any manipulation of the
control data or the engine data.
Level 2: Level for the device manufacturer
The device manufacturer can set speeds within the permissible ranges.
Besides, the control's dynamic parameters and the dynamics map may be
modified and power output reduced.
Level 3: Level for the service
With the exception of the most significant engine specific parameters, such as
engine output and boundaries of various characteristic map, all types of
modifications are permitted on this level.
Level 4: Level for the engine manufacturer
On this level, the entire programme as needed to programme the control is
accessible.
Level 5: Level for manufacturers of engines with user-specific software
This level is provided for parameters that are required for customer specific
software modifications or expansions.
Level 6: Level for the control manufacturer
On this level, the control functions may be manipulated directly. Therefore,
access on this level remains restricted to HEINZMANN.
Level 7: Level for development
This level remains reserved for the HEINZMANN development department.
As will have become evident from this survey any superior level is a proper superset of the
previous level, providing upward compatibility. At the end of the software manuals a
detailed list of all parameters together with their respective levels is available. The
maximum level is determined by the diagnostics device used (PC or Hand Held
Programmer) and cannot be changed. There exists, however, the option of reducing the
currently valid level by means of a special menu item of the PC-programme or via the
parameter 1800
Level
. Reducing the level is, however, bound to affect the number of
parameters and functions that can be accessed.
