Detailed CGCM-DLR Unit Tag Descriptions
Appendix
E
Reverse Power Protection Outputs from CGCM Unit
•
RevPwrFlt
- This tag is used to communicate the occurrence of a Reverse
Power 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.
Rotating Diode Monitor Inputs to CGCM-DLR Unit
•
RotDiodeFltOutEn
- When this tag is a 1 in the configuration, and a
Shorted or Open Rotating Diode Fault occurs, the Fault Relay is
energized. When this tag is a 0 in the configuration, these conditions have
no effect on the Fault Relay.
•
OpenDiodeMonitorLevel
- This tag sets the percent ripple at which the
rotating diode monitor alarm announces when an open diode condition
occurs.
•
ShortedDiodeMonitorLevel
- This tag sets the percent ripple at which
the rotating diode monitor alarm announces when a shorted diode
condition occurs.
•
DiodeMonitorTimeDly
- This tag sets the amount of time the
CGCM-DLR unit takes before the CGCM-DLR unit announces that the
rotating diodes have an anomaly.
•
MainPole
- This tag sets the number of poles of the main field of the
generator.
•
ExciterPole
- This tag sets the number of poles of the exciter field of the
generator.
Rotating Diode Monitor Outputs from CGCM Unit
•
RotDiodeFlt
- This tag is used to communicate the occurrence of a
Shorted or Open Rotating Diode 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.
•
ShortedRotDiodeFlt
– This tag indicates that a Shorted Rotating Diode
Fault caused the RotDiodeFlt tag to be set.
•
OpenRotDiodeFlt
- This tag indicates that an Open Rotating Diode
Fault caused the RotDiodeFlt tag to be set.
Phase Rotation Check Inputs to CGCM-DLR Unit
•
PhRotFltOutEn
- When this tag is a 1 in the configuration, and a Phase
Rotation Fault occurs the Fault Relay is energized. When this tag is a 0 in
the configuration, a Phase Rotation Fault has no effect on the Fault Relay.
