I've had to?deal with that rotary switch in the past, making conversion from single phase to 3 phase when the converter failed. I had someone at felder walk me through it over the phone. That was the?only way to get it done without them sending a tech to our location?thousands of miles from any of their locations.
Good luck,
Jason
