Wiring the ATS22 with S6U suffix for 2-wire control.
All Altistart 22's ending with S6U suffix (120V)
Basic wiring examples
The S6U requires constant 120VAC to terminals CL1 (hot) and CL2 (neutral).
For a freewheel stop:
Connect a jumper from Terminal LI1 to LI2.
Connect a jumper from Terminal CL2 to COM.
Close a dry contact between Terminals CL1 and LI2 for a run forward. Open this connection for a freewheel stop.
For a controlled stop:
Do not jumper LI1 to LI2, wire LI1 to CL1, use run contact between CL1 and LI2, and program SEt - dEC = ramp down time.
