Prestart Segmenting Setup
The Menu 5 contains a configuration named Basic Segment Number (parameter 4544).
In the following cases the basic segment number is configured to the default value (1):
• There is only one single DSLC-2 in use
• There are multiple DSLC-2 / MSLC-2 installed, which work on a common bus, which cannot be sepa-
rated. (only one segment available)
When the application contains switching elements between DSLC-2s and/or MSLC-2s proceed with following
rules:
1. Draw an online diagram of your application with all generators, breakers and utility inputs. Then arrange the
DSLC-2 (and MSLC-2) at the according breaker. Refer to Figure 3-42.
Figure 3-42: Example of an online diagram
2. Draw the measurement systems arrows between unit and bars (refer to Figure 3-43).
Please consider following rules:
• The DSLC-2 is placed at the generator breaker.
• The MSLC-2 can be placed at the tie-breaker and at the utility breaker.
• The MSLC-2 at the utility is doing the utility voltage measurement always with system A measurement.
The system B measurement is connected to the busbar.
• The MSLC-2 at the tie-breaker has usually the system A on the left side and the system B on the right
side.
