Job was shut down and constantly tripping breaker. Troubleshot it and found 220 vac breaker was bad. Replaced it. Then elevator would flash a2 until I made up locks and then it would run approx. 2-3 inches down and throw an E1 fault. Sent board to World for repair and when I wired it back up it is still doing same thing. The guy from Access states its bad green board. Also I have LEV run button and it is totally not functional on this unit only. Should I send board back again. Will IMS lead me towards problem.
