Hanya mafi sauƙi don gyara matsalolin wutar lantarki ita ce yin odar sauya tsarin lantarki daga masana'anta na JDC.Ana ba da wannan akan tsarin musayar don haka yana da tsada sosai.
Kafin aikawa da tsarin musanya kuna iya son duba abubuwan da ke gudana:
Idan injin ba ya aiki kwata-kwata:
a) Bincika cewa akwai wutar lantarki a injin ta hanyar lura da hasken matukin jirgi a cikin ONOFF swich.
b) Idan wutar tana nan amma injin ya mutu amma yayi zafi sosai to ana iya yanke zafin zafin.A wannan yanayin jira har sai injin ya huce (kimanin % awa daya) sannan a sake gwadawa.
c) Makullin farawa mai hannu biyu yana buƙatar danna maɓallin START kafin a ja hannun.Idan aka fara jan hannun da farko to injin ba zai yi aiki ba.Hakanan yana iya faruwa cewa katako mai lanƙwasa yana motsawa (ko kuma an bumped) isasshe don sarrafa "angle microswitch" kafin a danna maɓallin START.Idan wannan ya faru a tabbata an fara tura hannun gaba ɗaya baya.Idan wannan matsala ce mai tsayi to yana nuna cewa mai kunnawa microswitch yana buƙatar daidaitawa (duba ƙasa).
d) Wata yuwuwar ita ce maɓallin START na iya zama kuskure.Idan kana da Model 1250E ko mafi girma to sce idan na'urar za a iya farawa da ɗaya daga cikin madadin maɓallan START ko maɓallan ƙafa.
e) Hakanan duba haɗin nailan wanda ke haɗa tsarin lantarki tare da na'urar maganadisu.
f) Idan clamping bai yi aiki ba amma clampbar yana raguwa yayin sakin maɓallin START to wannan yana nuna cewa 15 microfarad (10 μuF akan 650E) capacitor yayi kuskure kuma yana buƙatar maye gurbinsa.
g) Idan na'urar ta busa fis na waje ko kuma ta yi tafiyar cirewa lokacin da aka sarrafa ta to mafi kusantar sauƙi shine busa gada.Tabbatar cewa an cire injin ɗin daga tashar wutar lantarki kafin yin ƙoƙarin gyara na ciki.

Idan ƙulle haske yana aiki amma cikakken matsawa baya:
Duba cewa "Angle Microswitch" ana kunna shi daidai.
Ana sarrafa wannan maɓalli ta tagulla murabba'i (ko zagaye) wanda ke maƙala da kusurwar da ke nuni da na'ura. Lokacin da aka ja hannu sai katakon lanƙwasa yana juyawa wanda ke ba da juyi ga mai kunna tagulla.Mai kunnawa kuma yana aiki da microswitch a cikin haɗin lantarki.
Canja mai kunnawa
Mai kunnawa Microswitch akan Model 1000E
(Sauran samfuran suna amfani da ƙa'ida ɗaya)
Actuator daga ciki
Mai kunnawa kamar yadda aka gani daga cikin wutar lantarki

Cire hannun waje sannan ku shiga. Ya kamata ku iya jin microswich yana danna ON da KASHE (idan babu hayaniyar baya da yawa).
Idan mai kunnawa bai danna ON da KASHE ba sai a lankwasa katakon lankwasa daidai sama domin a iya ganin mai kunna tagulla.Juyawa katakon lanƙwasawa sama da ƙasa.Mai kunnawa ya kamata ya juya don mayar da martani ga katako mai lanƙwasa (har sai ya kama a tasha) - Idan bai yi ba to yana iya buƙatar ƙarin ƙarfi.A kan rashin ƙarfi na 1250E yawanci yana da alaƙa da sukurori na hular M8 guda biyu a ƙarshen mashin mai kunnawa ba tare da tsauri ba.Idan mai kunnawa ya juya ya kama Ok amma har yanzu bai danna microswitch ba to yana iya buƙatar daidaitawa.Don yin wannan da farko cire na'urar daga tashar wutar lantarki sannan cire panel access panel.
a) A kan Model 1250E za'a iya daidaita wurin kunnawa ta hanyar buga dunƙule wanda ke wucewa ta cikin mai kunnawa.Ya kamata a gyara dunƙule kamar yadda maɓallin ke dannawa lokacin da gefen ƙasa na katako mai lanƙwasa ya motsa kusan 4 mm.(A kan 650E da 1000E ana samun daidaitawar hankali ta hanyar lanƙwasa hannun microswitch.)
b) Idan microswitch bai danna ON da KASHE ba ko da yake mai kunnawa yana aiki da kyau to ana iya haɗa shi da kansa a ciki kuma yana buƙatar maye gurbinsa.
Tabbatar cewa an cire injin ɗin daga tashar wutar lantarki kafin yin ƙoƙarin gyara na ciki.
V3 microswitchA maye gurbin V3 mai dacewa:
Lambar ɓangaren RS: 472-8235
Ƙididdiga na yanzu: 16 amps
Ƙimar wutar lantarki: 250V AC
Nau'in lever: tsayi
c) Idan na'urarka tana da na'ura mai ba da hanya tsakanin hanyoyin sadarwa to ka tabbata an canza ta zuwa matsayin "NORMAL".(Za a sami ƙulla haske na Oaly idan canjin yana cikin "AUX CLAMP" matsayi)
Idan clamping yayi kyau amma Clampbars ba sa saki lokacin da injin ya kashe:
Wannan yana nuna gazawar da'irar demagnetising na baya.Mafi m dalilin zai zama hura 6.8 ohm ikon resistor.Hakanan duba duk diodes da kuma yiwuwar manne lambobi a cikin relay.
Tabbatar cewa an cire na'urar daga wutar lantarki kafin yin ƙoƙarin gyarawa na tsaka-tsaki.
Wirewound resistorA dace mai sauyawa resistor:

Na yau da kullun S1.00
Idan inji ba zai lanƙwasa ma'auni mai nauyi ba:
a) Bincika cewa aikin yana cikin speifements na inji.Musamman lura cewa don 1.6 mm (ma'auni 16) lankwasawa dole ne a sanya sandar tsawo zuwa katako mai lanƙwasa kuma mafi ƙarancin faɗin leɓe shine mm 30.Wannan yana nufin cewa aƙalla milimita 30 na abu dole ne ya fito daga gefen lanƙwasawa na clampbar.(Wannan ya shafi duka aluminum da gani.)
kunkuntar lebe ne mai yiwuwa idan lanƙwasawa ba cikakken tsawon injin ɗin ba ne.
b) Hakanan idan kayan aikin bai cika sarari a ƙarƙashin madaidaicin ba to ana iya cutar da aikin.Don sakamako mafi kyau koyaushe cika sararin da ke ƙarƙashin clampbar tare da guntun karfe mai kauri iri ɗaya da kayan aikin.(Don mafi kyawun clamping Magnetic yanki ya kamata ya zama karfe koda kuwa aikin ba karfe bane)
Wannan kuma ita ce hanya mafi kyau da za a yi amfani da ita idan ana buƙatar yin kunkuntar lebe akan kayan aikin.
