What are the positions for the Logic Input Switch on the ATV31?

The logic input switch assigns the logic input common link to 0v (Source logic), 24 V (Sink logic), or floating.

Up (factory Default) is for 0 volt, Middle is Floating and Bottom is Sink or 24 V.

NOTE: When the logic input is configured for Sink logic, grounding the input signals can result in unintended activation of drive controller functions.

This is switch SW1 that is located on the bottom left hand side of control board.
