8. Power management (AGC 14x only)
8.1 About AGC 14x power management
8.1.1 About AGC 14x power management
Both AGC 145 and 146 are designed to work as main controllers and/or tie breaker controllers in applications
with other Multi-line 2 products such as AGC-4 or AGC 200. Since the AGC 14x variants are not able to syn-
chronise, they are meant to be used in applictions where synchronising of the mains breaker and/or the tie
breaker is not necessary. Even though it is not possible to synchronise the mains/tie breaker with AGC 145 or
146 equipped, it is still possible for the generators to synchronise onto busbar. This means that the genera-
tors are able to synchronise to the busbar with the tie breaker and the mains breaker already closed, but it is
not possible to back synchronise the mains- or tie breaker.
The table below shows the differences in the AGC 14x variants:

8.2 Single line diagrams
8.2.1 AGC 145
The diagram below shows an example of an application setup where an AGC 145 controls the mains breaker
and communicates over the CANbus with three AGC 242 on the generators. The diesel generators are able
to synchronise onto the busbar, but the mains breaker is not.
