Inzwa yoxinzelelo lwe-17216318 ifanelekile kwi-VOLVO roller / grader

Xa ukhetha i-sensor efanelekileyo, iintlobo ezahlukeneyo zoomatshini kunye nabalawuli abacwangcisiweyo kufuneka bahlawule ingqalelo kwiinkcukacha.Phantse wonke umatshini wale mihla ekufuneka ulungiswe okanye uphuculwe uneemfuno ezithe ngqo kwiintlobo zedatha ekufuneka ifunyenwe.Akunjalo kuphela umatshini oneemfuno ezithile, kodwa kunye ne-CPU kunye nemodyuli yenkqubo yokulawula ineemfuno zabo.

Ngenxa yolu ntlukwano, kukho iintlobo ngeentlobo zabenzi boluvo ezikhoyo, kwaye uluvo ngalunye lwenzelwe umsebenzi othile kwaye lubonelela ngoqwalaselo lwedatha oluthe ngqo.Kweli phepha, inkqubo yokukhetha inzwa elungileyo kwizicelo ezahlukeneyo iya kufundwa ngononophelo.Ngokukodwa, ulwazi olusisiseko lokusebenzisa iiparamitha zoomatshini ukumisela uhlobo loluvo oluza kunyulwa, indlela yokuchonga i-sensor polarity efunekayo, kunye nendlela yokukhetha phakathi kwamazwe aqhelekileyo avulekileyo kwaye avaliweyo aya kuqaliswa.

Iindidi ezahlukeneyo zeendidi zoluvo

Ubudlelwane phakathi kwemveliso ozama ukuyibona kunye nokukhethwa kwenzwa kubaluleke ngaphezu kwayo nayiphi na enye into.Ngesiqhelo, ukuba ufumanisa ukuba wenze ukhetho olungalunganga kule miba, ungafumana indlela yenkqubo okanye imodyuli ukubuyisela umva polarity yesiginali.

Nangona kunjalo, ukuba udidi loluvo olungalunganga lukhethiwe, imveliso ayinakufunyanwa kwaphela.Akukho bungakanani beesekethe ezinokusombulula le ngxaki.

Ipholarity yoluvo

Uninzi lwamagalelo edijithali kufuneka luqhagamshelwe kumbane we-DC, oqhele ukuba yi-10 ukuya kuma-24 vDC.Nangona kunjalo, ezinye iinkqubo zinokusebenzisa i-120 vAC okanye ngamanye amaxesha i-24 vAC yolawulo lombane.Ezi ziluncedo kwezinye iimeko ezikhethekileyo, kuba azidingi ukuntsonkotha konikezelo lwamandla eDC kwaye zifuna kuphela isiguquli.

Ezi zixhobo zoluvo ze-AC zidla ngokungacwangciswanga kunye ne-polarity, kunye namaphepha edatha abonisa ukuba imithwalo inokufakwa kwiingcingo ezishushu okanye iingcingo zamandla ezingathathi hlangothi, ezidla ngokuba mdaka kunye neblue ukusuka kwiintambo zomsila ezifakwe ngaphambili.

Inzwa ye-AC kufuneka ikhethwe kuphela xa imodyuli yegalelo lomlawuli iqwalaselwe njenge-AC.Oku akuqhelekanga njenge-DC, kodwa olu hlobo kufuneka lusetyenziswe ukuba imodyuli yenzelwe igalelo le-120 vAC.

Ngokuqhelekileyo kuvulwa okanye kuvalwe ngesiqhelo

Omnye umehluko kwiikhrayitheriya zokukhetha i-sensor kukukhetha phakathi kokuvula ngokuqhelekileyo (NO) kwaye kuvalwe ngokuqhelekileyo (NC).Ngaphakathi kobubanzi benkqubo yolawulo lwedijithali, ngokwenene ayenzi mahluko, okoko nje inkqubo ibhaliwe kwinzwa efanelekileyo.

Ukwahlukana kuphela kwe-NO / NC kukuba ukuba uhlobo lwenzwa lukhethiweyo ukwenza isiphaluka senzwa sivule ngaphezu kwe-50% yobomi bayo, inokugcina amandla.Ugcino lweendleko lunokuba luncinci, kodwa xa iindleko zokuqala zenzwa zifana, kunentsingiselo ukukhetha ezona zixhobo zisebenzayo zoyilo.
