Figure 6-4 Power Low Fault
Figure 6-4 shows a Power Low fault. After the fault occurrence, the
inverter had a DC Voltage High fault. In this case, the display added the
fault codes 0200 0000 plus 1000 0040 to become 1200 0040.
If the faults have the same first digit (such as 1000 XXXX) the 1 remains
the same and only the second block of four numbers add to the original
fault code.

Fault Description
8000 0000
Power Module
Generated by the power electronics to protect
the switching module.
4000 0000
Power Module
Generated by the power electronics to protect
the switching module.
1000 0800
PLL Fault
The inverter was unable to match the grid
frequency. This is usually caused by an
unstable power grid.
1000 0400
AC Voltage High
The grid voltage exceeded the limits in Table
4-3.
1000 0200
AC Voltage Low
The grid voltage dipped below the AC limits
in Table 4-3.
