Detailed CGCM-DLR Unit Tag Descriptions
•
DeadBusGenV_LoLim
- This tag configures the minimum voltage that
must be present on the generator to allow the breaker to close under a
Dead Bus condition.
•
DeadBusGenV_HiLim
- This tag configures the maximum voltage that
must be present on the generator to allow the breaker to close under a
Dead Bus condition.
•
DeadBusClosureEn
– Setting this tag to 1 lets the generator achieve
breaker closure with a dead bus.
•
BusA_PhOffset
- This tag configures a phase angle added to the measured
bus A phase angle. It is used to compensate for phase shift across sensing
transformers.
•
BusA_V_Scaler
- This tag configures a multiplier by which the measured
bus A voltage is multiplied. It is used to compensate for ratio error across
sensing transformers.
•
BusB_PhOffset
- This tag configures a phase angle added to the measured
bus B phase angle. It is used to compensate for phase shift across sensing
transformers.
•
BusB_V_Scaler
- This tag configures a multiplier by which the measured
bus B voltage is multiplied. It is used to compensate for ratio error across
sensing transformers.
•
BusA_B_Select
– This tag selects which reference bus the CGCM-DLR
unit attempts to synchronize to.
•
V_Match
Gain-This tag sets the Proportional Gain parameter for Voltage
Matching mode
Synchronizing Outputs from CGCM-DLR Unit
•
SyncDeadBus
- This tag indicates that all conditions have been to allow a
DeadBus synchronization
•
AutoSync
– This tag follows the AutoSyncEn tag setting in the Scheduled
Write tag.
•
CheckSync
- This tag follows the CheckSyncEn tag setting in the
Scheduled Write tag.
•
PermissiveSync
- This tag follows the PermissiveSyncEn tag setting in the
Scheduled Write tag.
•
SyncFailure
– This tag indicates that the synchronization attempt failed.
•
UndefinedSyncMode
– This tag indicates that a synchronization was
initiated when none of the synchronization modes were asserted.
•
SyncModeConflict
– This tag indicates that multiple Synchronization
modes were selected.
•
BusRot_ABC_ACB
– This tag reports the rotation sequence of the
reference bus in 3-phase metering. In single phase metering, these bits
reflect the configuration value.
