,OSSOF%XCITATION/UTPUTSFROMTHE#'#-5NIT
•
LossExcFlt - This tag is used to communicate the occurrence of a Loss of
Excitation 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.
3HORTED%XCITATION/UTPUTFROMTHE#'#-5NIT
•
Spare2 - Indicates when the excitation output short circuit protection is
active. When this tag is a 1, it indicates that a shorted output exists and the
excitation current output has been clamped to a very low level. The tag is
reset by either setting the tag SoftwareExcEN = 0 or by cycling the control
power to the CGCM unit.
/VEREXCITATION6OLTAGE)NPUTSTOTHE#'#-5NIT
•
OvrExcFltOutEn - When this tag is a 1 in the configuration, and an
Over-excitation Fault occurs (as defined by the OvrExcV_Setpt tag), the
Fault Relay is energized. When this tag is a 0 in the configuration, an
Over-excitation Condition has no effect on the Fault Relay.
•
OvrExcV_Setpt - This tag configures the over-excitation voltage setpoint
that the CGCM unit uses to recognize when an over-excitation condition
is present. When the condition occurs, the CGCM unit starts timing
toward a trip based on the Over-excitation Time Delay.
•
OvrExcV_TimeDly - This tag configures the time to trip the unit once the
over-excitation voltage setpoint has been exceeded.
/VEREXCITATION6OLTAGE/UTPUTSFROMTHE#'#-5NIT
•
OvrExcFlt - This tag is used to communicate the occurrence of an
Over-excitation 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.
'ENERATOR/VERVOLTAGE)NPUTSTOTHE#'#-5NIT
•
Ovr_V_FltOutEn – When this tag is a 1 in the configuration, and an
Over-voltage Fault occurs (as defined by the Ovr_V_Setpt tag), the Fault
Relay is energized. When this tag is a 0 in the configuration, an
Over-voltage Condition has no effect on the Fault Relay.
•
Ovr_V_Setpt – This tag configures the generator over-voltage setpoint
that the CGCM unit recognizes an over-voltage condition is present and
starts timing to trip based on the Over-voltage Time Delay.
•
Ovr_V_TimeDly - This tag configures the time to shutdown the unit
once the generator Over-voltage Setpoint has been exceeded.
