Frequency Tab

Use this tab to enter overfrequency and underfrequency settings.

Parameters

Over-Frequency

Setpoint

This value establishes the generator overfrequency setpoint at which the CGCM recognizes an overfrequency condition and starts timing to trip, based on the overfrequency time delay. Valid values range from 30.00 to 70.00 Hz; the default value is 60.50 Hz.

Delay

This value establishes the time to annunciate and, if configured, to trip the fault output relay once the generator overfrequency setpoint has been exceeded. Valid values range from .10 to 300.00 seconds; the default value is 1.00 second.

Under-Frequency

Setpoint

This value establishes the generator underfrequency setpoint at which the CGCM recognizes an underfrequency condition and starts timing to trip, based on the underfrequency time delay. Valid values range from 30.00 to 70.00 Hz; the default value is 59.00 Hz.

Delay

This value establishes the time to annunciate and, if configured, to trip the fault output relay once the generator underfrequency setpoint has been exceeded. Valid values range from .10 to 300.00 seconds; the default value is 1.00 second.
