Greetings, I recently purchased a MM350p from an online auction. Brought it home and it needed all new cords. Not an issue, I worked with the local Airgas and now All connected up with new. Today I decided it was time to fire up and I re-linked for 1-phase 240vac, plugged it in, hit the switch and.... I am getting "help7" and "help9" codes. Input power checked and re-checked.. is perfect. Any suggestions?
