Good find, phasing of each car in the group was somthing that used to be done regularly, I still did that when I was in the field. I advise the younger guys to do this when they Mod, even though most of the installation documents we see now don't address this anymore.
Hey e311, id like to understand this more. Is this only for the bus supply or for all supplies? I take it the group controller has an output for the bus to each individual lift controller. This would come from the original power supply to the group and then the pcb's split it where it is all needed. So are we just talking about +/- being reversed and thus 180 degree out of phase? What was your process for getting the cars in phase with each other, as I cant say I have ever had to worry about this?
