Raws li qhov tsis muaj kev nyab xeeb rov qab ua rau muaj kev nyab xeeb ntau dua thiab muaj qee tus neeg tseem tsis paub txuas kev nyab xeeb rov qab raug thiab nyob rau hauv tus qauv. Qhov no tau coj mus rau qee qhov kev khwv lag luam poob thiab kev raug nplua. Piv txwv li, lub tshuab SAWNING hauv lub tuam txhab alarmed thaum hmo ntuj, thiab pom tias lub teeb ntawm kev nyab xeeb relay module tsis nyob. Tom qab kev tshawb nrhiav, nws tau pom tias cov fuse ua ntej tau hlawv. Tom qab hloov lub fuse, cov relay tseem tsis ua haujlwm, thiab cov ntxhiab tsw ntawm cov plaub hau hlawv tuaj yeem hnov tsw. Tom qab ntawd, nws tau pom tias cov xaim ntawm kev nyab xeeb relay tsis yog lawm. Lub taub hau nruab nrab tsis txuas nrog 24V raws li qhov xav tau. Tus thawj Relay rov pib dua siv sab hauv fais fab mov, thiab sab nraud fais fab tsis txuas tau tom qab hloov, thiab lwm yam ua rau cov relay kom puas. Vim li no, cov ntaub ntawv nyab xeeb hauv qab no relay wireing specifications yog txheeb tawm
I. Cov ntsiab cai tseem ceeb
Kev cais tawm: Kev Nyab Xeeb Circuit Court (Chaw nres tsheb thaum muaj xwm ceev / Kev nyab xeeb / Kev Tswj Xyuas Kev Nyab Xeeb (tswj / teeb liab), thiab tsis muaj kab ke lossis lub davhlau ya nyob twg.
Dual Rov Qab Los: Lub tswv yim yuav tsum muaj dual contact thiab ob lub xov hlau, thiab cov terminals sib txawv tau txuas nrog; Cov xov hlau yog cov khoom qub (tooj liab) thiab tib tus ntoo khaub lig - seem (ntau dua lossis sib npaug 0.5mm²).
Ii. Inputy Circuit Court
Siv ib txwm kaw cov neeg (ib txwm muaj, txhaum tawm), thiab lov tes taw tsis nquag qhib (anti {{{adhesion).
Ob chav ua si tau nyob hauv ib qho kev sib cais, thiab lub pob thaum muaj xwm ceev nres yog mechanically yuam kom disconnect.
Xaim gauge: tsau ntau dua li lossis sib npaug zos rau 0.5mm, coj mus sib luag ntau dua lossis sib npaug rau 0.75mm², rwb thaiv tsev ntau dua los yog sib luag rau 500v; Stripping 1 ~ 2mm, txias nias lub davhlau ya nyob twg.
III. Kev Tawm Tsam Circuit Court
Kev Nyab Xeeb Thauj (Tus Hu Nkauj / Tsav Tsheb) yuav tsum tau siv sijhawm dua
Nruab nrog ib txwm kaw cov tswv yim kaw kev sib cuag nrog lub davhlau ya nyob twg tshwj xeeb, kev saib xyuas ywj pheej ntawm kev thauj khoom.
IV. Lub Zog Hluav Taws Xob thiab Kev Ua Si
Independent fais fab mov (AC220V / DC24V), tsis qhia rau PLC, thiab lwm yam; 1a Fuse / McB hauv cov koob nyob ntawm lub tswv yim xaus.
PE lub davhlau ya nyob twg txuas nrog rau kev nyab xeeb hauv av ib leeg, tsis yog hauv series; xaim loj dua los yog sib npaug rau 1.5mm², ground tsis kam dua lossis sib npaug rau 4ω.
V. Terminals thiab xaim
Siv anti -} loosenting davhlau ya nyob twg, m3 torque 0.8 ~ 1.2 lab, m}} ~} · m.
Cov xaim khiav raws cov zawj, nrog bend diamital ntau dua los yog sib luag rau 6 lub sij hawm lub taub hlau; anti {- Kev co hlua tau siv ntawm cov chaw sib cav, cov raj xaim muaj ntau dua los yog sib npaug ntawm 80 degree, thiab kev nyab xeeb hauv paus, thiab kev nyab xeeb hauv kev pom zoo kom ua txiv kab ntxwv.
VI. Kuaj cov ntaub ntawv pov thawj
Muaj nuj nqi: Nres nres thaum muaj xwm ceev ib txwm nyob ntawm, tawm tawm; Ib Leeg -} Circuit System, dual - kev ua txhaum tsis tuaj yeem rov pib dua.
Rwb thaiv tsev ntau dua los yog sib luag rau 10m11 (500v meter), av txuas ntxiv tsawg dua lossis sib npaug ntawm 0.1ω (Milliohm meter).
VII. Taboos thiab hauv paus
Nws yog txwv tsis pub txuas tsis-}} kev nyab xeeb thauj mus rau kev nyab xeeb thiab siv tsis yog- Tau lees paub nruab nrab nruab nrab; Siv los tiv thaiv {- loosening kua nplaum rau terminals ntawm cov chaw co, thiab ntxiv cov plua plav npog tom qab cov xaim.
Lub hauv paus: E ISO 13849-1, IEC 61508, GB 50254 thiab hom phau ntawv qhia.
