The back-EMF voltage generated across the start winding causes a small current to flow in the start winding and potential relay coil because they are in the same circuit. Check all electrical connections inside control box for tightness. Wye-delta open transition 3-phase motors. When the back-EMF has built up to a high enough value referred to as pick-up voltage the contacts between terminals 1 and 2 will be picked up opened.
