4.1.1 Standard functions
This section includes functional descriptions of standard functions as well as illustrations of the relevant appli-
cation types. Flowcharts and single-line diagrams will be used in order to simplify the information.
The standard functions are listed in the following paragraphs.
The table below describes the genset modes that are available, depending on the variant of the CGC to be
used.
Application Comment
Automatic Mains Failure (AMF) (no back sync.) CGC 413
Island operation CGC 412/CGC 413
Load takeover CGC 413
On the hardware point of view, the CGC 412 has a lighter specification than the CGC 413.
The table below describes which points differ from each other.
Feature (terminal numbers) Available on CGC 412 Available on CGC 413
Mains measurement (term. 28 to 32) No Yes
Extra multi-inputs (term. 58 and 59) No Yes
Extra binary inputs (term. 56 and 57) No Yes
