4.2 Displayed Fault Codes
The vacuum fluorescent display (VFD) provides the following codes when a fault has
occurred:
Faulted:
Fault 1000 0400
AC Voltage High
0 Watts
1400 kWh
267 VAC
300 VDC
Starting up from a faulted state:
NOTE: In this case the fault refers to the last fault detected.
If the inverter is in a faulted state, the RED LED blinks and the VFD scrolls through
the screens shown in the faulted example above. The text of the fault describes the
specific fault condition that the inverter experienced.
If the inverter is no longer experiencing the condition that caused it to fault (ex. the
AC voltage climbs above 264V then drops below 264V), the RED LED stops blinking
and the inverter starts the five minute count-down timer. During these five minutes,
the display will also show the last fault.
4.2.1 Multiple Faults
If the inverter detects multiple faults at one time, the inverter displays the text of
the first fault detected.
For multiple faults, the numerical values of the fault codes are added.
Example:
The above example displays the AC Voltage High fault (1000 0400), plus a DC
Voltage Low fault (1000 0020). This might occur at night, when the panel voltage is
low (because of darkness) and the utility voltage was above the limits defined in
Table 2.2.
