Error code
Error or protection definition
Error display
HF
IDU mismatching error
Immediate display, spot check
H4
L (L0/L1) error occurs three times in one hour, reporting H4,
and this error is not recoverable.
After H4 error, spot check may be performed on the latest
three L errors (not limited to L0, L1). For example: report L0-
L4-L8-L9-L0-L1 within one hour, and report H4 error.
The errors for spot check are L9, L0, and L1.
