The 8430MPSV29 relay is not operating, contacts are not changing state when the three phases are connected?

Unit picks up, contacts change state, when all criteria are correct. Phases must all be present, and in the correct rotation, and the voltage must be above the set point.
Most common problem when the unit will not operate is the phases are not in the correct rotation. Suggest switching 2 phases.
