This manual is for use by qualified personnel only
0045 Interrupt 2 Timeout S
This fault indicates that the Xantrex
inverter has detected that an
interrupt 2 timeout has occurred.
The control unit controller board
performs a conversion validation
of analog-to-digital data within the
A to D converters. If validation of
the conversion is not performed
within 500mS, an interrupt 2
timeout fault occurs.
• Internal A to D
converter error
•CPU error
0047 Software Test S
This fault indicates that the Xantrex
inverter has detected that a
software test fault has occurred.
This is a simulated fault used for
debugging purposes.
0048 Bad Memory S This fault indicates that the Xantrex
inverter has detected that the
SRAM DIMM on the control unit
controller board has failed. The
control unit performs a series of
tests to confirm the validity of the
SRAM, and the memory module
has produced errors.
• Internal SRAM error
•CPU error
0049 Control Voltage
Low
S
This fault indicates the Xantrex
GT500 E GI and Xantrex GT630 E
GI has detected the 230 Vac
auxiliary AC voltage has dropped
below 165 Vrms for 2 consecutive
cycles.
• Fuses -F5, -F6, -F7
blown.
• Units with optional
ride-through: Xantrex
UPS is defective.
0054 Control Voltage
High
S
This fault indicates the Xantrex
GT500 E GI and Xantrex GT630 E
GI has detected the 230 Vac
auxiliary AC voltage has exceeded
270 Vrms for 2 consecutive cycles.
• External control
voltage source
defective.
• Units with optional
ride-through: Xantrex
UPS is defective.
0062 Matrix
Temperature
S This fault indicates that the Xantrex
inverter has detected that the
temperature of the IGBT matrix
aluminium heatsink has exceeded
the maximum allowed value of 95
°C.
• External cooling fan
inoperable
• Air flow on heat sink
impeded due to
accumulation of debris
• Operation above rated
ambient temperature
for an extended period
of time
