Faults and Warnings
Code Message Warning Description Possible problem and Solution(s)
33 Grid Under
Frequency level 1 Grid side Frequency under the
parameter [Grid Under Fre-
quency Level 1] Possible problem
• The grid frequency is outside the
operation range
Solution(s)
• Check the grid frequency
• Check the grid parameter
34 Grid CB Trip CB20 (AC Disconnect/Grid
circuit breaker) was tripped
during operation Possible problem
• Short circuit in the grid
Solution(s)
• Check the wiring connections
35 Grid Over Voltage
Level 2 Grid side Voltage over the
parameter [Grid Over Voltage
Level 2] Possible problem
• The grid voltage is too high
Solution(s)
• Check the grid voltage
• Check the grid parameter
36 Grid Under Voltage
Level 2 Grid side Voltage Under the
parameter [Grid Under Voltage
Level 2] Possible problem
• The grid voltage is too low
Solution(s)
• Check the grid voltage
• Check the grid parameter
37 Grid Under Frequency
Level 2 Grid side Frequency Under the
parameter [Grid Under Fre-
quency Level 2] Possible problem
• The grid frequency is outside the
operation range
Solution(s)
• Check the grid frequency
38 Grid Over Frequency
Level 2 Grid side Frequency Over the
parameter [Grid Over Frequency
Level 2] Possible problem
• The grid frequency is outside the
permitted range
Solution(s)
• Check the grid frequency
40 Parameters
Version Error Different version between the
NVSRAM parameter table and
the program parameter table Possible problem
• Different version between the NVSRAM
parameter table and the program
parameter table
Solution(s)
• Initialize the parameter menu setting in
the GUI and reset faulted parameter
• Change the PCB module
