Detailed CGCM Unit Tag Descriptions Appendix E
Reverse Power Protection Outputs from the 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 the CGCM 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, a these conditions has
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
unit takes before the CGCM unit announces 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 the 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 the CGCM 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.
