Hi,
I have some faulty Symmetra Lx Power modules type SYPM4KI. Few of them have faulty board INVERTER BD. Model 640-0476J REV 9.I will name fault as an" starting problem of Power module". When I turn UPS on, this Power module does not go ON, and display in Diagnostic position is indicating :
Power module - faulty
Row Status Dump data :0804 02A0 8000 2080 0002 0840 7C 0700 0000 59 8483 0000.
When I change mentioned INVERTER BD. with good one, Power module is working ok.
Now I am asking you guys for your comment and help to eliminate problem on this "board".
I have some questions :
- Can I buy separately boards -parts of Power module?
- How can I check INVERTER BD. to verify for correct operation( signal on test points or something similar).
-What are telling to me Row Status Dump data's and how can I decode them?
p.s.
Four days before I send " task about IM module of Symmetra Lx " but I did not have any comment or help from You ! It was my first post to forum.
Regards -Mehdi,
