025 FB_EOR_INVALID_OUTPUT_REQUES
T
Feedback enable_output_relays
detected an illegal combination of
generator mode and RF output side for
output relay configuration.
Turn the power switch off (O) then on again (|).
If the error reappears, replace the control board.

FB_CAL_OVERVOLTAGE
Overvoltage condition discovered during
current sensor (Isns) calibration. Make
sure the load is as specified in
calibration instructions.
FB_CAL_OVERCURRENT
Overcurrent condition discovered during
voltage sensor (Vsns) calibration. Make
sure the load is as specified in
calibration instructions.
Check the loads attached during calibration. It is likely that
the attached load has a higher impedance than specified.
Correct the attached load.
If the error reappears, replace the control board.
If the error reappears, replace the RF board.

INVALID_INIT_ERROR
A bad error code was supplied by a
powerup self test routine on the master
side.
FB_RESET_ERROR
Master unable to reset feedback
microprocessor at initialization.
WSI_RAM_ERROR ST Microelectronics
ST Microelectronics RAM failed test
during initialization.
DPRAM_ERROR
DPRAM failed test during initialization.
ROM_CRC_ERROR Flash Memory
CRC Test of ST Microelectronics Flash
Memory failed during initialization.
Turn the power switch off (O) then on again (|).
If the error reappears, replace the control board.
105 ALL_CAL_DATA_INVALID
Calibration data invalid at powerup, and
could not be recovered.
Calibrate the unit.
If the error code reappears, replace the battery on the
control board.
If the error code reappears, replace the control board.
106 CORRECTED_BATRAM_CRC_DATA
Battery backed RAM CRC test failed
during initialization, but the data was
restored from the RTC data.
Reported to serial port only.
May indicate a bad battery or failed U3.
107 BATRAM_FAILED_TO_HOLD_CRC_
DATA
Battery backed RAM CRC test failed
during initialization. An attempt to correct
the problem failed.
Reported to serial port only.
Replace the battery.
If the error code reappears, replace the control board (failed
U3).
