Frequency Page
The Frequency page is used to configure the parameters that are 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-DLR 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.
