4.4.3.5.1 Independent Sync. Check Function
General notes
The device provides two independent "Sync Check" functions for the voltage comparisons
generator to busbar and busbar to mains. The criteria are the same like for the according
internal self-executed synchronization.
The easYgen provides two command variables available for the LogicsManager input:
• 02.29 Sync.Check gen./busb •
• 02.32 Sync.Check mns/busb •
WARNING!
No dead bus interlocking
Synch. Check is intended to be a redundant check function enhancing system security.
Don't use for MCB control!
The Sync. Check functionality is available in every application mode. The command
variables are independently calculated and depending on the same configurations, like
the self-executed GCB and MCB close commands. The sync. Check function has no
influence on any frequency or voltage biasing. There is no relationship to the Sync. Check
mode for the internal self-executed synchronization.
The Synch. Check command variables do not care about:
• Possible dead busbar closure capabilities •
• Internally calculated self-executed circuit breaker close orders
•
• Synchronization control conditions, like »mains settling time «
•
Variables and Parameters
»02.29 Sync.Check gen./busb« depends on
• Voltage •
• Frequency •
and
• Phase angle •
The command variable »02.29 Sync.Check gen./busb« is true if the synchronization
conditions are matched according to (GCB) parameters:
• 5701: Pos. freq. differential •
• 5702: Neg. freq. differential •
• 5700: Voltage differential •
• 8825, 8824: Phase angle compensation •
