Detailed CGCM-DLR Unit Tag Descriptions
238
• 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.
