Vim tias tus contactor tsis nqus yog feem ntau vim tias qhov coil ntawm contactor nws tus kheej tsis tau txais cov khoom hluav taws xob, thiab tsis tshua muaj vim tias cov kauj kaw los yog kos kabmob. Koj tuaj yeem txiav txim nrog ib lub tshuab ntsuas ntau los ntsuas qhov kev khiav hauj lwm muaj hluav taws xob ntawm kev sib txuas, thiab thaum tsis muaj hluav taws xob, yuav tsum nrhiav kom paub tias txoj haujlwm ntawm kev tiv tauj nrog kev sib txuas nrog lub xov tooj nrog tus chiv contactor yog ib qho zoo lossis tsis; thaum kawg, nrhiav kom paub qhov teeb meem txhaum cai. (Ntawm chav kawm, yog tias lub coil muaj voltage, tseem tsis tau nqus, nws tuaj yeem hloov ncaj qha)
1. Lub sij hawm luv luv ntawm tus contactor coil.
2. Xyuas seb lub hwj huam hluav taws xob yog qhov zoo li cas.
3. Kos lub hwj chim yog ac los yog DC.
4. Kuaj xyuas seb lub hwj chim puas nyob thiab seb lub Circuit Court pib qhib hluav taws xob.
