Appendix E Detailed CGCM Unit Tag Descriptions
Generator Over-voltage Outputs from the CGCM Unit
• Ovr_V_Flt – This tag is used to communicate the occurrence of an
Over-voltage 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.
Inputs to the CGCM Unit
• Undr_V_FltOutEn - When this tag is a 1 in the configuration, and an
Under-voltage Fault occurs (as defined by the Undr_V_Setpt tag), the
Fault Relay is energized. When this tag is a 0 in the configuration, an
Under-voltage Condition has no effect on the Fault Relay.
• Undr_V_Setpt - This tag configures the generator under-voltage setpoint
that the CGCM unit uses to recognize an under-voltage condition. When
the condition occurs, the CGCM unit starts timing toward a trip.
• Undr_V_TimeDly - This setting establishes the time to trip the unit once
the generator Under-voltage Setpoint has been exceeded.
• EngineIdle – Setting this tag to 1 enables Soft Start mode and disables the
under-frequency, under-voltage, and Loss of PMG protections until the
generator is at rated speed.
Generator Under-voltage Outputs from the CGCM Unit
• Undr_V_Flt - This tag is used to communicate the occurrence of an
Under-voltage 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.
Loss of Sensing Inputs to the CGCM Unit
• LossSensingFltOutEn - When this tag is a 1 in the configuration, and a
Loss of Sensing Fault occurs the Fault Relay is energized. When this tag is a
0 in the configuration, a Loss of Sensing Condition has no effect on the
Fault Relay.
Loss of Sensing Outputs from the CGCM Unit
• LossSensingFlt - This tag is used to communicate the occurrence of a Loss
of Sensing 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.
