Notes
This parameter is only effective if start stop mode (parameter
is configured to "Generator load".
The maximum generator load must be configured higher then the minimum
generator load for proper operation.
2 The dynamic determines when to start or stop the next genset and shows the
following behavior:
Starting genset
The control requests a certain amount of additional load depending on the
dynamic. It may start two or more gensets to supply the required load. Also
refer to the following example.
Stopping genset
The dynamic determines how soon a genset will be stopped. It prevents con‐
tinuous start and stop if only a few gensets are in operation. In this case, the
remaining gensets would not reach the maximum limit if one genset stops (if,
for example, two gensets with 100 kW rated load, a minimum load of 40 %
and a maximum load of 70 % are operated, the second genset will be shut
down if both reach 40 kW and the remaining engine would operate with
80 kW and request the next engine and so on). The more gensets are run‐
ning, the less the influence of this parameter. Also refer to the following
example.
[Low] Starting genset
A larger genset is requested and it will take longer until the next change is
required. The engines are operated with more reserve power. The requested
load is calaculated so that the gensets will be loaded with 25 % of the range
between minimum and maximum generator load (parameters
& 5763 Ä p.
Stopping genset
The genset will shut down at a lower limit and be operated longer. The
number of gensets in operation will remain constant for a wider range of load.
The load on the remaining gensets must not exceed 25 % of the range
between minimum and maximum generator load (parameters
& 5763 Ä p.
Moderate Starting genset
A medium genset is requested. The requested load is calaculated so that the
gensets will be loaded with 50 % of the range between minimum and max‐
imum generator load (parameters

Stopping genset
