text: <s>[INST] gv 3000 fault code F 3 not F03 any ideas I have a GV3000 where it starts up with F 3, F in the first 7 seg and 3 in the last flashing with every led at the same time.Tech support suggested the 15v rail for encoder... yes that is for a F03 fault. My 15v rail is ok along with all the other rails. No button presses / combination will do anything.A top panel from another larger drive will give me access but starts with the mismatch code for controller / power stage but would allow me to start the matching process but as this belongs to a different drive I cannot spare it.I suspect the memory is corrupted but unable to clear it.Any Ideas?Thanks in anticipationTim Smith [/INST] Did you already try what is suggested in the User Manual ? Attached is a screenshot of the indications.... Hope this helps... - fuzzy logic \\n </s>
