Detailed CGCM-DLR Unit Tag Descriptions
Appendix
E
Loss of Operating Power Inputs to CGCM-DLR Unit
•
LossPMGFltOutEn
- When this tag is a 1 in the configuration, and a Loss
of PMG Fault occurs the Fault Relay is energized. When this tag is a 0 in
the configuration, a Loss of PMG Condition has no effect on the Fault
Relay.
Loss of Operating Power Outputs from CGCM Unit
•
LossPMGFlt
- This tag is used to communicate the occurrence of a Loss of
PMG Fault to the host Logix controller. When this tag is a 1, it indicates
that a fault has occurred. The tag is latched until the host Logix controller
resets it by setting the FltReset tag.
Reverse VAR Inputs to CGCM-DLR Unit
•
RevVARFltOutEn
- When this tag is a 1 in the configuration, and a
Reverse VAR Fault occurs (as defined by the Rev_kVAR Setpt tag), the
Fault Relay is energized. When this tag is a 0 in the configuration, an
Overvoltage Condition has no effect on the Fault Relay.
•
Rev_kVAR_Setpt
- This tag configures the generator reverse kVAR
setpoint at which the CGCM-DLR unit recognizes a reverse kVAR (loss
of excitation) condition is present and starts timing to trip based on the
Reverse kVAR fault Delay setting.
•
Rev_kVAR_TimeDly
- This tag configures the time to
shutdown/annunciate once the generator reverse kVAR setpoint has been
exceeded.
Reverse VAR Outputs from CGCM-DLR Unit
•
RevVARFlt
- This tag is used to communicate the occurrence of a Reverse
VAR Fault to the host Logix controller. When this tag is a 1, it indicates
that a fault has occurred. The tag is latched until the host Logix controller
resets it by setting the FltReset tag.
Definite Time Over-frequency Inputs to CGCM-DLR Unit
•
OvrFreqFltOutEn
- When this tag is a 1 in the configuration, and an
Over-frequency Fault occurs (as defined by the OvrFreqSetpt tag), the
Fault Relay is energized. When this tag is a 0 in the configuration, an
Over-frequency Condition has no effect on the Fault Relay.
•
OvrFreqSetpt
- This tag configures the generator over-frequency setpoint
at which the CGCM-DLR unit recognizes an over-frequency condition is
present and starts timing to trip based on the Over-frequency Time Delay.
•
OvrFreqTimeDly
- This tag configures the time to shutdown/annunciate
once the generator Over-frequency setpoint has been exceeded.
