Zilla FAQ19 Feb 2007 11:35 pm
Questions about S1 and S2 on the Zilla wiring diagrams:
Which end gets S1 and which gets S2 for forward vs reverse depends on the internal motor construction. This is why I don’t list it on the drawing. There should be some wiring indication relevant to direction on the motor prints. The forward contactor will go up when energized, and that will connect A2 to one of the field connections. Which one just determines which direction you end up moving. It’s not uncommon to get it backwards the first time and have to swap them.
