Renaming Messages, Checking Configurations
After parameterization of a flexible function, the following steps should be noted:
•
Open matrix in DIGSI
•
Rename the neutral message texts in accordance with the application.
•
Check configurations on contacts and in operation and fault buffer, or set them according to the require-
ments.
Further Information
The following instruction should be noted:
•
As the power factor does not differentiate between capacitive and inductive, the sign of the reactive
power may be used with CFC-help as an additional criterion.
Settings
Addresses which have an appended “A” can only be changed with DIGSI, under “Additional Settings”.
The table indicates region-specific default settings. Column C (configuration) indicates the corresponding
secondary nominal current of the current transformer.
