(3) Tshawb xyuas seb puas muaj qhov luv luv hauv lub maub los. Disconnect qhov chaw nres nkoj serial txuas hlau nyob tom qab ntawm tus maub los, thiab siv ib lub 'meter' los kuaj seb puas muaj luv luv ntawm pins 6 thiab 9 ntawm qhov chaw nres nkoj serial. Xyuas kom meej tias tsis muaj qhov luv luv Circuit Court (uas yog, tsis muaj luv luv Circuit Court ntawm tus pins 6 thiab 9 ntawm qhov chaw nres nkoj serial tom qab ntawm tus maub los).
(4) Xyuas seb qhov hloov hluav taws xob puas muaj DC 5V tso zis. Tshem tawm cov kab txuas txuas ntawm qhov chaw nres nkoj tom qab ntawm tus maub los, tig lub hwj chim, thiab siv ib lub 'meter' los ntsuam xyuas seb lub tshuab hluav taws xob hloov hluav taws xob puas muaj DC 5V tso zis, lossis pom qhov muag saib seb lub teeb taw qhia ib sab ntawm lub zog hloov hluav taws xob puas yog. lit. Xyuas kom meej tias qhov tso zis voltage ntawm switching fais fab mov yog qhov qub.
(5) Tshawb xyuas seb puas muaj cov kab hluav taws xob ntawm lub tshuab hluav taws xob puas lawm (strument test).
(6) Xyuas seb lub connector sab hauv ntawm tus maub los poob los yog xoob.
(7) Kev ua haujlwm tsis zoo hauv Circuit Court, teeb meem lossis hloov nrog cov chaw tsim khoom.
6. Lub vijtsam zaub pom qhov muag plooj lossis xim txawv txav:
(1) Tshawb xyuas seb cov khoom siv cable puas muaj kev sib cuag zoo. Qhib lub vaj huam sib luag thiab tshuaj xyuas cov kab hluav taws xob ntawm lub vijtsam zaub thiab lub rooj tsav xwm tswj kev laus lossis kev sib cuag tsis zoo. Qee lub sij hawm, los ntawm reinserting thiab unplugging cov connectors ntawm ob kawg ntawm cov zaub cable, nws yuav rov qab mus rau qhov qub.
(2) Tso cov teeb meem cable los yog teeb meem tso saib. Hloov nrog cov chaw tsim khoom.
7. Rov pib dua maub los:
Xyuas seb qhov DC 5V tso zis ntawm lub zog hloov hluav taws xob puas ruaj khov (vim li ± 0.2V). Feem ntau, nws yog tshwm sim los ntawm ib tug loj dhia ntau yam, instability, los yog kev puas tsuaj rau lub sab hauv ntawm lub hwj chim tso zis voltage.
8. Hloov fais fab mov yam tsis muaj DC5V tso zis (qhov taw qhia lub teeb tsis ci):
(1) xyuas kom meej tias lub load tsis muaj luv luv Circuit Court. Disconnect qhov chaw nres nkoj serial txuas hlau nyob tom qab ntawm tus maub los, thiab siv ib lub 'meter' los kuaj seb puas muaj luv luv ntawm pins 6 thiab 9 ntawm qhov chaw nres nkoj serial. Xyuas kom meej tias tsis muaj qhov luv luv Circuit Court (uas yog, tsis muaj luv luv Circuit Court ntawm tus pins 6 thiab 9 ntawm qhov chaw nres nkoj serial tom qab ntawm tus maub los).
(2) Xyuas kom meej tias lub input davhlau ya nyob twg muaj AC (170V ~ 250) V, 50Hz voltage input.
(3) Lub zog hloov hluav taws xob nws tus kheej raug puas tsuaj. Tshem tawm lossis hloov nrog cov chaw tsim khoom.
9. Thaum pib ntawm qhov kev sim, qhov kub ntawm lub cub tawg tsis nce mus rau qhov kub thiab txias rau lub sijhawm ntev:
(1) Lub cub tawg hlau qhib. Tshawb xyuas seb lub tshuab hluav taws xob hluav taws xob puas yog qhib hluav taws xob lossis lub zog thauj khoom tsis txaus (ib pawg ntawm cov hluav taws xob hluav taws xob tawg). Ib qho cuab yeej siv tau los ntsuas qhov tsis kam ntawm cov hlau hauv lub tshuab hluav taws xob, uas ib txwm muaj txog 10-15 ohms.
(2) Lub solid-state relay yog burnt tawm los yog puas. Tshawb xyuas seb cov khoom siv-state relay puas puas los yog cov kab tswj kev sib cuag tsis zoo.
(3) voltage tsawg dhau.
10. Tsis muaj cua sov lossis tsis muaj cua sov
(1) Lub cub tawg hlau qhib. Xyuas seb lub cub hluav taws xob puas qhib, qhib lub hau npog ntawm lub qhov cub hluav taws xob, thiab siv ib lub 'meter' los ntsuas cov nqi hluav taws xob ntawm lub cub hluav taws xob, uas feem ntau yog li ntawm 10-15 ohms. (Xyuas seb qhov kev sib tshuam ntawm lub davhlau ya nyob twg posts muaj kev ntseeg siab tiv tauj)
