Advantages of such a solution:

– No engineering and wiring costs for the second system

– Further increased security since all four output contacts

are normally operated in series

– No problems with synchronizing where the

manual synchronizing system is seldom used.

Specific settings for synchronizing and paralleling are stored

in a parameter set. Devices with seven parameter sets have

seven times the same parameters, with the possibility of

individual setting. That way, seven paralleling points with

individual settings may be operated. Firstly, the parameter

set, or the circuit breaker to be synchronized has to be

selected. Then the synchronizing process can be started.

The software-driven link between parameter set and

paralleling point guarantees the correct assignment of the

setting values to the related plant components.
