Figure 6-2 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 the fault
(e.g. 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 also shows the last fault.
Multiple Faults
If the inverter detects multiple faults at one time, the inverter display
cycles through all detected faults.
For multiple faults, the numerical values of the fault codes are added as
Figure 6-3 AC Voltage High/DC Voltage Low Fault
Figure 6-3 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, due to darkness, and the utility voltage was above the limits
