Ungakuxazulula kanjani ukwehluleka kwesikrini esithintwayo-12 head linear weweight

1.Vula ikhabethe elisebusweni bokushintsha njengesithombe esingezansi, futhi uthole amandla kagesi.

2.Bese ukala 203+ kanye 203- byi-multimeter, i-voltage evumelekile kufanele ibe yi-DC24V.

4.Cisha, sebenzisa i-multimeter ukuze uxhume i-Pin 1 ne-Pin 2 yesixhumi ku-203+ no-203- ukuze uhlole ukuthi ixhunyiwe yini .

5.Uma enye yazo ingaxhumekile, kusho ukuthi intambo inqanyuliwe kusixhumi, pls qaqa futhi uyilungise .

6.Bese kuthi uma kulinganiswa u-203+ no-203-, i-voltage ayiwona u-24V okusho ukuthi amandla kagesi aphukile noma ikhebula likhishiwe.

A: Okokuqala, hlola ukunikezwa kwamandla, nqamula isikrini futhi uqinisekise ukuthi isixhumi asixhumeki nesikrini, bese uyasusa.203+/203-kusuka ekunikezeni amandla.

B: Linganisa lawa matheminali amabili ukuze uhlole ukuthi amandla aku-24V noma cha.

Uma kungeyona i-24V, kusho ukuthi ugesi uphukile;uma yebo okusho ukuthi inkinga iyenzeka ngemuva kwekhebuli.

Buyisela emuva i-203+/203- buyela ekunikezeni amandla, bese ukhipha ipulaki ebhodini lokuphakela amandla .

Bese ukala iphinikhodi ukuze ubone ukuthi ingu-24V noma cha.

8.Uma amandla engajwayelekile, ngokwesibonelo, ahluka ukusuka ku-24V, lokho kusho ukuthi ibhodi lokunikezwa kwamandla liphukile.

Uma amandla engu-24V, okusho ukuthi ibhodi lomama liphukile, noma ikhebula liphukile noma ibhodi likagesi liphukile - ibhodi lokuphakela amandla eline-voltage yomthwalo lidonselwa phansi, lidinga ukufaka esikhundleni sebhodi elisha likagesi ukuze kutholakale lokhu. isimo.

9.Cabanga ukuthi ibhodi lokuphakela amandla lihle, bese uthola ukuthi ingabe ibhodi lomama liphukile noma ikhebula; xhuma ikhebula buyisela ebhodini lokuphakela amandla, bese ukhipha i-P07 ebhodini lomama .

10.Linganisa i-voltage yalezi zikhonkwane ezimbili.

Uma kungeyona i-24V, okusho ukuthi ibhodi lomama liphukile, futhi kudingeka kushintshwe ibhodi elisha.

Uma i-voltage ingu-24V, okusho ukuthi intambo ngemuva iphukile.

Ikhebuli iyintambo eluhlaza okwesibhakabhaka, ikhebula engu-18V+ exhumeka ku-back plate, kanye ne-18V- exhunywe nesitobhi esiphuthumayo .

11.Ngemva kokuqeda ukuhlola, uma yonke ikhebula ijwayelekile, Qinisekisa ukuthi isikrini siphukile.Cabanga ukuthi inkinga ngokuvamile ikhebula elikusixhumi liyanqamuka, noma ibhodi lokuphakela amandla liphukile.
