Line Voltage Control - double contactor three phase motor starter controlling a reversible three phase motor (rev 08 Aug 2006) (Note: L1 becomes T3 and L3 becomes T1 when the reverse relay is actuated.) The motor must be STOPPED before REVERSING unless the contactor allows for on-the-fly reversing. The coils are locked out via the NC contacts (M1, M2) usually contained within the mechanical interlock. When Coil #M1 is engaged, Coil #M2 is locked out and vice-versa.
