0040 Programming
Software
S This code indicates that the
Xantrex inverter has detected
that the system is in
Programming mode. This fault
does not indicate any
malfunction with the Xantrex
GT500 E & Xantrex GT630 E, but
is merely an indication that the
system software is in the process
of being downloaded into the
EEPROMs of the control unit.
0041 State Invalid S The state machine implemented
within the control unit system
software governs the operation of
the Xantrex GT500 E & Xantrex
GT630 E. This fault indicates that
the Xantrex inverter has detected
an unknown system variable and
has encountered an invalid state.
• Internal RAM error
•CPU error
0042 Serial EEPROM
Write Error
S This fault indicates that the
Xantrex inverter has detected a
serial EEPROM write error. The
control unit controller board
performs a verification check of
data written to ROM compared to
what is read back.
• Internal ROM error
•CPU error
0043 Serial EEPROM
Timeout
S This fault indicates that the
Xantrex inverter has detected
that when writing data to the
serial EEPROM, a confirmation
timer of 300mS has expired.
• Internal ROM error
•CPU error
0044 Bad NOVRAM
Memory
S This fault indicates that the
Xantrex inverter has detected
that one of the two non-volatile
memory banks on the control unit
controller board has failed. The
control unit performs a series of
tests to confirm the validity of the
NOVRAM, and one of the two
banks has produced errors.
• Internal NOVRAM
