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
