FPGA Failure
FPGA diagnostics failed during either
power up or run time.
In this rare event, the relay will automatically
restart. If the failure occurs three times in seven
days, the LCD displays the
FPGA FAIL screen.
Contact the SEL factory or your Technical Ser-
vice Center.
NOTE: Prior to firmware version R108, the relay
did not automatically restart. Contact the SEL
factory or your Technical Service Center.
