WARNING: Disconnect primary power prior to servicing.

Frame Length = (Superframe Length – Pos. Pilot Length – 18) / 4;

• Local Length: (Unsigned Decimal integer, displayed only, not user configurable –

see below)

Local Length shall be calculated, written to the FPGA register, and displayed based

on the following formula:

Local Length = Frame Length – National Length – 4;

Figure 3-44 FPGA Configure 5/5, Restore Defaults

FPGA Configure 5/5 screen consists of the following four buttons.

• Restore Factory (Defaults)

• Restore Defaults

• Initialize FPGA

• Save as Defaults

Restore Factory Defaults loads all FPGA registers with the values defined as default

initialization values in the API, if defined, followed by a re-initialization of the FPGA.

Save as Defaults saves the current GUI settings that may have been modified by the user,

in non-volatile memory as default values for subsequent initialization and startup.

Restore Defaults recalls the previous set of values saved as default, followed by a

re-initialization of the FPGA.

Initialize FPGA manually starts the initialization sequence defined in the API, using the

current values indicated in the GUI.

Note: Restore Factory Defaults and Restore Defaults causes a warning window to pop up.

It states “WARNING: Restore will re-initialize exciter.”

• Clicking OK will start the restore and re-initialize process.

• Clicking cancel will abort the restore and re-initialization sequence.
