This prevents the 469 from recognizing an additional start if motor current goesto zero during an open transition.808724A2.CDRCC1CC2469BLOCK TRIP STOP START REDUCED VOLTAGECONTACTORFULL VOLTAGECONTACTORCC1SEAL IN4693 AUXCC2 SEAL IN808725A1.CDRMOTORAMPS(% FLA)When the currrent falls belowthe Transition Level and/or theTimer expires, the AuxiliaryRelay activates for 1 secondTransition TimeTIMEsignifiesOpen Transition3 x FLATransitionLevelFLA
