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.
