EDR-5000
IM02602007E
States of the Inputs of the Sync-check Module
Name
Description
Assignment via
ExBlo1-I
Module Input State: External Blocking1
[Protection Para
/Global Prot Para
/Sync-check]
ExBlo2-I
Module Input State: External Blocking2
[Protection Para
/Global Prot Para
/Sync-check]
Bypass-I
State of the module input: Bypass
[Protection Para
/Global Prot Para
/Sync-check]
BkrCloseInitiate-I
State of the module input: Breaker Close Initiate with synchronizm
check from any control sources (e.g. HMI / SCADA). If the state of
the assigned signal becomes true, a Breaker Close will be initiated
(Trigger Source).

Signals of the Sync-check Module (States of the Outputs)
Signal
Description
Active
Signal: Active
ExBlo
Signal: External Blocking
LiveBus
Signal: Live-Bus flag: 1=Live-Bus, 0=Voltage is below the LiveBus threshold
LiveLine
Signal: Live Line flag: 1=Live-Line, 0=Voltage is below the LiveLine threshold
SynchronRunTiming
Signal: SynchronRunTiming
SynchronFailed
Signal: This signal indicates a failed synchronization. It is set for 5s when the breaker is still open
after the Synchron-Run-timer has timed out.
SyncOverridden
Signal:Synchronizm Check is overridden because one of the Synchronizm overriding conditions
(DB/DL or ExtBypass) is met.
VDiffTooHigh
Signal: Voltage difference between bus and line too high.
SlipTooHigh
Signal: Frequency difference (slip frequency) between bus and line voltages too high.
AngleDiffTooHigh
Signal: Phase Angle difference between bus and line voltages too high.
Sys-in-Sync
Signal: Bus and line voltages are in synchronizm according to the system synchronizm criteria.
In-Sync Allowed
Signal: In-Sync Allowed
