The Frequency tab is used to configure the CGCM unit parameters related to the
over-frequency and under-frequency protection functions.
•
Over-frequency Setpoint - Establishes the generator over-frequency
setpoint. The tag
OvrFreqSetpt in the configuration table stores this
parameter, expressed in Hz.
•
Over-frequency Delay - Establishes the amount of time in seconds that the
frequency must be above the over-frequency setpoint before the CGCM
unit annunciates the fault. This parameter is stored in tag
OvrFreqTimeDly in the configuration table.
•
Under-frequency Setpoint - Establishes the generator under-frequency
setpoint. The tag
UndrFreqSetpt in the configuration table stores this
parameter, expressed in Hz.
•
Under-frequency Delay - Establishes the amount of time in seconds that
the frequency must be below the under-frequency setpoint before the
CGCM unit annunciates the fault. This parameter is stored in tag
UndrFreqTimeDly in the configuration table.
