Ukusombulula njani ukungaphumeleli kwesikrini sokuchukumisa-intloko ye-12 yentloko yesilinganisi somgca

1.Vula ikhabhinethi esebusweni bokutshintsha njengomfanekiso ongezantsi, kwaye ufumane unikezelo lwamandla.

2.Ke umlinganiselo 203+ kunye 203- ngomultimeter, amandla ombane asebenzayo kufuneka abe yi-DC24V.

4.Ukucinywa kwamandla, sebenzisa i-multimeter ukudibanisa i-Pin 1 kunye ne-Pin 2 kwi-203 + kunye ne-203- ukujonga ukuba ixhunyiwe.

5.Ukuba omnye wabo akaqhagamshelwanga, ngoko kuthetha ukuba ucingo lunqanyuliwe kwikhonkco, pls qhaqha kwaye uyilungise.

6.Ke xa umlinganiselo we-203+ kunye ne-203-, i-voltage ayikho i-24V ethetha ukuba ukunikezelwa kwamandla kwaphukile okanye intambo ikhutshwe.

A: Okokuqala, vavanya unikezelo lwamandla, qhawula isikrini kwaye uqinisekise ukuba isinxibelelanisi asidibanisi nesikrini, emva koko sisuse.203+/203-ukusuka kunikezelo lwamandla.

B: Linganisa ezi terminasl zimbini ukujonga ukuba amandla angama-24V okanye hayi.

Ukuba ayingo-24V, ngoko kuthetha unikezelo lombane olwaphukileyo; ukuba ewe whcih uthetha ingxaki eyenzeka ngasemva kwentambo.

Beka umva i-203+/203- ubuyele kunikezelo lwamandla, emva koko ususe iplagi kwibhodi yonikezelo lwamandla .

Kwaye ulinganise iPin ukuze ubone ukuba yi-24V okanye hayi.

8.Ukuba amandla akaqhelekanga, umzekelo, ahluka ukusuka kwi-24V, oko kuthetha ukuba ibhodi yobonelelo lwamandla yaphukile.

Ukuba amandla yi-24V, oku kuthetha ukuba ibhodi yomama yaphukile, okanye intambo yombane yaphukile okanye ibhodi yonikezelo lwamandla yaphukile -ibhodi yobonelelo lwamandla kunye nombane womthwalo uyatsalwa phantsi, kufuneka ithathe indawo yebhodi yonikezelo lwamandla entsha ukufumanisa oku. imeko.

9.Thatha ibhodi yonikezelo lwamandla ilungile, emva koko ufumanise ukuba ibhodi yomama yophukile okanye intambo; intambo yeplagi ibuyele kwibhodi yonikezelo lombane, emva koko uyisuse i-P07 kwibhodi yomama.

10.Linganisa amandla ombane ezi zikhonkwane zimbini.

Ukuba ayingo-24V, oku kuthetha ukuba ibhodi yomama yaphukile, kwaye kufuneka utshintshe ibhodi entsha.

Ukuba i-voltage yi-24V, oku kuthetha ukuba intambo emva kophukile.

Intambo yi-buzzer eblue, intambo engu-18V+ eqhagamshela kwipleyiti yangasemva, kunye ne-18V- eqhagamshelwe kwindawo yokumisa kaxakeka.

11.Emva kokugqiba ukujonga, ukuba yonke intambo iyinto eqhelekileyo, i-Confirm that screen is broken.Cinga ingxaki ubukhulu becala ikhebula kwi-connector iyanqanyulwa, okanye ibhodi yonikezelo lwamandla yaphukile.
