3 Parameterization of HEINZMANN Speed Governors
Programmer PG 02

Any of the characteristics and maps available within the control unit can be displayed two-
or three-dimensionally in separate windows. By this, the profile and shape of any specific
characteristic or map can immediately be viewed. The actual point within the characteristic
or map at which the system is currently operating will be displayed online. To make any
adjustments does not require detailed knowledge of the interrelation between the parameter
numbers and the points of the characteristic or map since a special input section has been
provided offering assistance with regard to the peculiarities of parameterizing
characteristics and maps. This feature will prove very helpful to avoid erroneous input.
DcDesk 2000 is being continuously updated and enhanced by additional functions.
HEINZMANN particularly recommend the use of DcDesk 2000 for testing and initial
commissioning. Similarly, when servicing the system, DcDesk 2000 will prove a great
advantage for diagnosis and trouble shooting.

Parameter Value Ranges
Each parameter is assigned a particular value range. As there is a multitude of parameters
and functions, there also exists a great number of value ranges. Furthermore, the parameter
value ranges can be viewed by means of the PC or the hand held programmer.
For speed parameters, however, a common value range is provided. As a standard, it is set
to 0..4000 rpm which allows to run engines up to maximum speeds of approx. 3.500..3.600
rpm. There must exist some reserve for overspeed monitoring.
For certain parameters the value ranges cannot be explicitly specified in advance, but must
be communicated to the control by the user. This applies to all parameters indicating
physical measurements such as measurements from pressure or temperature sensors.
Some parameters are assigned a value range that is capable of two states only, viz. 0 or 1.
This type parameters are used to activate or switch over particular functions or to indicate
states of errors or of external switches, etc. Parameters with this value range are confined
to the lists 2 (Measurements) and 3 (Functions).
In that case, state "1" signifies that the respective function is active or that the respective
error has occurred, whereas state "0" signals the function to be inactive resp. that no error
has occurred.
The identifiers of change-over switches or of parameters selecting between two functions
always in clude an
Or
(e.g.: 2812
SwitchDroop2Or1
). The function preceding
Or
will be
active when the parameter value is = 1 whilst the function after
Or
will be active when the
parameter value is = 0.
