EMERSON Go Hloov Sib Nqus Sensor
TopWorx engineers zoo siab los muab kev pab cuam ntawm GOTM Hloov cov khoom. Txawm li cas los xij, nws yog tus neeg siv khoom lub luag haujlwm los txiav txim siab txog kev nyab xeeb thiab tsim nyog ntawm cov khoom hauv lawv daim ntawv thov. Nws tseem yog tus neeg siv khoom lub luag haujlwm rau nruab qhov hloov pauv siv cov lej hluav taws xob tam sim no hauv lawv thaj av.
Ceev faj- Hloov kev puas tsuaj
- Hloov yuav tsum tau nruab raws li cov cai hluav taws xob hauv zos.
- Kev sib txuas xov hlau yuav tsum muaj kev nyab xeeb zoo.
- Rau ob-circuit keyboards, kev sib cuag yuav tsum tau txuas nrog tib lub polarity thiaj li yuav txo tau txoj kab-rau-kab luv luv.
- Hauv damp ib puag ncig, siv daim ntawv pov thawj cable caj pas los yog cov dej noo zoo sib xws los tiv thaiv cov dej / condensation los ntawm kev nkag mus rau hauv lub hub.
Kev phom sij - Kev siv tsis raug
Tag nrho cov keyboards yuav tsum tau ntsia raws li qhov yuav tsum tau muaj ntawv pov thawj.
Mounting cov lus qhia rau tus qauv thiab latching hloov
- Txiav txim siab qhov chaw ua haujlwm xav tau.
- Txiav txim siab qhov chaw ntawm qhov chaw hnov ntawm GO™ Hloov.
- Muab qhov hloov pauv thiab lub hom phiaj nyob rau hauv ib txoj hauj lwm uas ua kom lub hom phiaj tuaj nyob rau hauv cov keyboards sensing cheeb tsam.
In Daim duab 1, lub hom phiaj tau muab tso tseg kom nres ntawm sab nraud ntawm lub hnab ntawv pom. Qhov no yog ib qho mob me me rau kev ua haujlwm ntev ntev.
In Daim duab 2, lub hom phiaj tau muab tso tseg kom tsis txhob zoo nyob rau hauv lub hnab ntawv sensing uas yuav ua kom ntseeg tau ntev kev ua haujlwm.
Ferrous lub hom phiaj yuav tsum muaj tsawg kawg yog ib lub cubic nti loj. Yog tias lub hom phiaj tsawg dua ib lub cubic inch loj, nws yuav txo qis kev ua haujlwm zoo lossis lub hom phiaj yuav tsis raug kuaj pom los ntawm kev hloov.
In Daim duab 3, lub hom phiaj ferrous yog me me dhau los kuaj pom kev ntseeg tau nyob rau lub sijhawm ntev.
In Daim duab 4, lub hom phiaj muaj qhov loj thiab loj txaus rau kev ua haujlwm ntev ntev.
- Hloov yuav raug mounted nyob rau hauv txhua txoj hauj lwm.
Ib sab ntawm cov hlau tsis muaj hlau (Daim duab 5 thiab 6).
- Hloov mounted ntawm cov ntaub ntawv tsis sib nqus
Pom zoo rau cov txiaj ntsig zoo tshaj plaws
a). Khaws tag nrho cov ntaub ntawv ferrous yam tsawg 1 "los ntawm kev hloov.
b). Hlau muab tso rau sab nraum lub keyboards sensing cheeb tsam yuav tsis cuam tshuam rau kev ua hauj lwm.
Nws tsis pom zoo tias cov keyboards yog mounted ntawm ferrous hlau, vim qhov txo qis hauv qhov ntsuas qhov deb.
Qhib / Deactivate qhov hloov
a). Hloov nrog cov qauv kev sib cuag - muaj qhov ntsuas qhov chaw ntawm ib sab ntawm qhov hloov (A). Txhawm rau qhib, lub hom phiaj ferrous lossis sib nqus yuav tsum nkag mus rau qhov chaw nkag siab ntawm qhov hloov pauv (Daim duab 7). Txhawm rau deactivate lub hom phiaj yuav tsum txav mus rau sab nraud ntawm qhov chaw paub, sib npaug lossis ntau dua li qhov kev ncua deb ntawm lub rooj.
Txhawm rau qhib cov neeg sib cuag ntawm sab A (saib daim duab 10), lub hom phiaj yuav tsum nkag mus rau qhov chaw nkag siab A ntawm qhov hloov pauv (saib qhov ntsuas qhov ntau hauv Table x). Txhawm rau tshem tawm cov kev sib cuag ntawm sab A thiab qhib rau sab B, lub hom phiaj yuav tsum txav mus rau sab nraud ntawm qhov chaw paub txog A thiab lwm lub hom phiaj nkag mus rau qhov chaw paub B (Daim duab 11). Txhawm rau rov qhib cov neeg sib cuag ntawm sab A, lub hom phiaj yuav tsum tawm tag nrho qhov chaw paub txog B thiab lub hom phiaj yuav tsum rov nkag mus rau qhov chaw paub qhov A (Daim duab 13).
Sensing Range
Sensing ntau muaj xws li lub hom phiaj ferrous thiab hlau nplaum.
Tag nrho cov khoom siv hluav taws xob txuas nrog, suav nrog GO ™ Switches, yuav tsum raug tshem tawm tawm tsam dej nkag los ntawm cov kav dej. Saib daim duab 14 thiab 15 rau kev coj ua zoo tshaj.
Sealing Switches
In Daim duab 14, lub kaw lus kaw yog ntim nrog dej thiab xau hauv qhov hloov pauv. Nyob rau tib lub sijhawm, qhov no tuaj yeem ua rau qhov hloov pauv ua tsis tiav.
In Daim duab 15, qhov kev txiav tawm ntawm qhov hloov pauv tuaj yeem haum nrog cov ntawv pov thawj xov-ed cable nkag ntaus ntawv (tus neeg siv khoom) raws li cov chaw tsim khoom cov lus qhia txhawm rau tiv thaiv kev nkag mus rau dej ua rau lub sijhawm hloov tsis ua tiav. Ib lub voj drip nrog kev npaj rau dej kom khiav tau kuj tau teeb tsa.
Txuas ntawm Conduit los yog Cable
Yog tias qhov hloov pauv tau txuas rau ntawm qhov txav mus, nco ntsoov tias cov kav dej hloov pauv tau ntev txaus kom tso cai rau kev txav mus los, thiab muab tso rau tshem tawm kev khi lossis rub tawm. (Daim duab 16). Hauv damp daim ntawv thov, siv cov ntaub ntawv pov thawj cable caj pas los yog cov dej noo zoo sib xws los tiv thaiv dej / condensation los ntawm kev nkag mus rau hauv lub hub. (Daim duab 17).
Cov ntaub ntawv txuas
Tag nrho GO Switches yog cov hloov pauv qhuav, txhais tau tias lawv tsis muaj voltage poob thaum kaw, thiab lawv tsis muaj qhov xau tam sim no thaum qhib. Rau kev teeb tsa ntau lub tsev, cov keyboards yuav raug xaim nyob rau hauv series los yog nyob rau hauv parallel.
GO™ Hloov Wiring Diagrams
Hauv av
Raws li qhov yuav tsum tau muaj ntawv pov thawj, GO Switches yuav muab nrog lossis tsis muaj ib qho hauv av xaim. Yog tias tsis muaj cov xaim hauv av, tus neeg tsim khoom yuav tsum xyuas kom muaj kev sib txuas hauv av kom zoo rau lub kaw lus.
Cov xwm txheej tshwj xeeb rau Intrinsic Safety
- Ob qho kev sib cuag ntawm Ob Qhov Ncauj thiab cov ncej sib cais ntawm Ob Tug Ncej hloov, nyob rau hauv ib qho kev hloov yuav tsum tsim ib feem ntawm tib lub cev muaj kev nyab xeeb.
- Cov kev sib txuas sib txuas tsis tas yuav tsum muaj kev sib txuas rau lub ntiaj teb kom muaj kev nyab xeeb, tab sis muaj kev sib txuas hauv ntiaj teb uas tau txuas ncaj qha rau lub thawv hlau. Nquag ib qho kev nyab xeeb hauv qhov hluav taws xob tuaj yeem raug earthed ntawm ib qho chaw xwb. Yog tias siv lub ntiaj teb kev sib txuas, qhov cuam tshuam ntawm qhov no yuav tsum tau txiav txim siab tag nrho hauv txhua qhov kev teeb tsa. Piv txwv li los ntawm kev siv lub galvanically cais interface.
Lub davhlau ya nyob twg thaiv variants ntawm cov cuab yeej siv nrog lub hau uas tsis yog xim hlau uas ua rau muaj peev xwm electrostatic txaus ntshai thiab yuav tsum tsuas yog ntxuav nrog adamp daim ntaub. - Qhov kev hloov yuav tsum tau muab los ntawm ib daim ntawv pov thawj Ex ia IIC Intrinsically muaj kev nyab xeeb qhov chaw.
- Cov kev ya davhlau yuav tsum raug txiav tawm raws li qhov tsim nyog rau thaj tsam ntawm kev teeb tsa.
Terminal Block Wiring Rau Flameproof Thiab Ntxiv Kev Nyab Xeeb
- Lub ntiaj teb kev sib txuas sab nraud tuaj yeem ua tiav los ntawm kev txhim kho mounting. Cov fixings no yuav tsum nyob rau hauv stainless hlau los yog lwm yam uas tsis yog-ferrous hlau nyob rau hauv thiaj li yuav txo tau ob qho tib si corrosion thiab sib nqus cuam tshuam ntawm kev hloov ua haujlwm. Kev sib txuas yuav tsum tau ua raws li kev tiv thaiv kom tsis txhob xoob thiab sib tw (xws li nrog cov hlua / txiv ntseej thiab xauv lub tshuab ntxhua khaub ncaws).
- Cov khoom siv tau ntawv pov thawj tsim nyog yuav tsum tau muab tso rau hauv raws li IEC60079-14 thiab yuav tsum tswj hwm qhov kev tiv thaiv ingress (IP) qhov ntsuas ntawm lub qhov rooj. Lub cable nkag ntaus ntawv xov yuav tsum tsis txhob protrude nyob rau hauv lub enclosure lub cev (xws li yuav tsum tuav lub clearance mus rau lub terminals).
- Tsuas yog ib leeg lossis ntau tus neeg xyuas pib ntawm qhov loj 16 txog 18 AWG (1.3 txog 0.8mm2) yuav tsum tau nyob hauv txhua lub davhlau ya nyob twg. Lub rwb thaiv tsev ntawm txhua tus neeg xyuas pib yuav tsum txuas mus rau hauv 1 hli ntawm lub davhlau ya nyob twg clamphauv phaj.
Kev sib txuas lus thiab / lossis ferrules tsis raug tso cai.
Kev xaim yuav tsum yog 16 txog 18 ntsuas thiab ntsuas rau cov khoom siv hluav taws xob uas cim rau ntawm qhov hloov nrog qhov kev pabcuam kub ntawm yam tsawg 80 ° C.
Hlau davhlau ya nyob twg screws, (4) # 8-32X5 / 16 "stainless nrog annular nplhaib, yuav tsum tau nruj rau 2.8 Nm [25 lb-hauv].
Npog phaj yuav tsum tau nruj me ntsis mus rau lub davhlau ya nyob twg thaiv rau tus nqi ntawm 1.7 Nm [15 lb-hauv].
GO Hloov tuaj yeem xaim li PNP lossis NPN nyob ntawm qhov xav tau daim ntawv thov DMD 4 Pin M12 Connector.
