Protection Settings Sub Panel
This panel contains editable fields for Soft Start Ramp Time, Over Voltage Level, Over Excitation Level and
Timer, Under Voltage Level and Timer, Field Current Level and Timer and Voltage Imbalance Timer. For most
applications, the default values of these parameters should be used. These settings should be modified only in
special circumstances.
Soft Start Ramp Time Is the amount of time taken to ramp to the desired voltage at the generator output terminals.
Refer to Section 3 – Features and Protection for a detailed description of the Generator Soft Start function.
Over Voltage Level is the percentage of Regulator Voltage Set Point that triggers the Generator Over Voltage
protection feature. Refer to Section 3 – Features and Protection for a detailed description of the Generator Over
Voltage Shutdown feature.
Over Excitation Level is the current threshold that triggers the Field Over Excitation protection feature. Refer to
Section 3 – Features and Protection for a detailed description of the Field Over Excitation Shutdown feature.
Over Excitation Timer is the amount of time the regulator operates before shutting down due to an Over Excitation
fault. Refer to Section 3 – Features and Protection for a detailed description of the Field Over Excitation Shutdown
feature.
Under Voltage Level is the percentage of Regulator Voltage Set Point that triggers the Generator Under Voltage
protection feature. Refer to Section 3 – Features and Protection for a detailed description of the Generator Over
Voltage Shutdown feature.
Under Voltage Timer is the amount of time the regulator operates before shutting down due to an Under Voltage
fault. Refer to Section 3 – Features and Protection for a detailed description of the Generator Under Voltage Shut-
down feature.
Field Current Limit is the current threshold limit of the regulator. Refer to Section 3 – Features and Protection for
a detailed description of the Field Current Limiting protection feature.
Field Current Timer is the amount of time the regulator operates at its Field Current Limit before shutting down due
to a Field Current Limit fault. Refer to Section 3 – Features and Protection for a detailed description of the Field
Current Limiting protection feature.
