Duplicated Control System (hot stand-by operation)

For this redundancy concept two inpedendent "control units" are provided which are equipped with the same control components. One control unit is active (Main Unit) and the other (Secondary Unit) is in hot stand-by mode. In case of failure, there is an automatic switchover to the backup control unit.

This redundancy concepts ensures that there is no loss of any warning and alarm functions in case of failure.
