In the last six months I have lost three drives with the same fault code. Siemens reps say "dirty power", sounds to me like a bad I/O board. Anyone else have the same issue?
IMHO, throw the drive away. We installed one and have had problems with it. We have had NO problems with the Honeywells lately (looks like a Cutler Hammer).
I heard the local "S" branch won't even buy them anymore.
