6.4.6. List of failure codes and information messages.
The PSU indicates the operation status with the appropriate code. The codes are divided into two
groups,
marked with the initial letters "F" or "
I”.
The codes beginning with the letter "F" indicate a failure. The codes that begin with the letter "I" indicate the
correct operation of the PSU or repaired fault, involving, for example, fuse replacement: "I03 - BAT fuse
replaced”.
