Tom qab kev teeb tsa thiab siv lub tshuab hluav taws xob, nws yuav tso tawm hom roj, thawj lub tswb, lub tswb thib ob thiab ntsuas ntau yam. Tom qab countdown ntawm 30S, lub cuab yeej yuav ncaj qha mus rau hauv lub xeev ua hauj lwm. Nws tau raug calibrated ua ntej xa khoom. Yog tias nws tsis tsim nyog hloov lub tswb ntsuas, tsis tas yuav ua haujlwm hauv qab no.
Lub vaj huam sib luag ntawm ib leeg-taw tes-mounted vaj huam sib luag muaj cov concentration qhia cov raj digital, thawj lub tswb ntsuas, qhov taw qhia lub tswb thib ob thiab 4 nyees khawm.
Cov nyees khawm ntawm sab laug mus rau sab xis yog:
Kev teeb tsa khawm
Up / Down khawm
Kev lees paub khawm
Mute / Rov qab mus rau cov ntawv qhia zaub mov qub
Kev ua haujlwm specification
1. Teem lub tswb ntsuas thawj thiab thib ob, rau qhov ntsuas pa oxygen yog qhov siab thiab qis.
2. Restore Hoobkas chaw
3. Lub tswb nrov tuaj yeem raug tshem tawm ntawm lub sijhawm. Lub tswb nrov yuav cia li pib thaum lub tswb tom ntej tau muab, tsis muaj phau ntawv pib.
4. Thaum cov roj concentration ntau dua tus nqi ceeb toom thawj zaug, lub relay yog nqus, lub tswb nrov, thiab lub tswb ntsuas thawj theem yog nyob rau. Lub xeev ntawm relay tsis hloov thaum lub suab nrov yog silenced nyob rau hauv lub sij hawm.
5. Thaum cov roj yog combustible thiab cov concentration siab tshaj 100% LEL, lub ntsuas yuav cia li tua lub roj ntes.
6. Thaum cov ntawv qhia zaub mov nres, yuav tsis siv neeg tawm zaub mov tom qab 30S.
Cov ntawv qhia zaub mov ua haujlwm
1. Ua cov kauj ruam
Nkag mus rau hauv lub xeev ua haujlwm thiab tso saib tus nqi kuaj pom ntawm lub sensor txuas. Kev teeb tsa parameter:
Kauj ruam 1: Nias khawm, zaub 0000, thawj nixie raj flashing
Kauj ruam 2: Sau lo lus zais 1111 (tus neeg siv tus password), nias lub pobxaiv ib tug lej los ntawm 1 mus rau 9 tus lej, ces nias lub pobxaiv tus lej tom ntej nyob rau hauv lem (suav tus lej flashing), thiab ces nias khawmxaiv tus lej.
Kauj ruam 3: Tom qab tus password input, nias khawmthiab tso saib F-01. Koj tuaj yeem xaiv los ntawm F-01 txog F-06 los ntawm nias lub pob. Cov ntsiab lus ntawm kev ua haujlwm F-01 txog F-06 xa mus rau lub rooj 2. Piv txwv li, tom qab xaiv cov haujlwm F-01, nias khawmkom nkag mus rau qhov chaw ceeb toom thawj zaug, thiab tus neeg siv tuaj yeem teeb tsa lub tswb thib ib. Tom qab ua tiav ntawm kev teeb tsa, nias lub pobQhov ntsuas yuav pom F-01. Yog tias lwm qhov kev ntsuas yuav tsum tau teeb tsa raws li saum toj no, txwv tsis pub, koj tuaj yeem nias khawm
tawm ntawm qhov kev teeb tsa no.
Table 2: Muaj nuj nqi F-01 txog F-06 tshaj tawm
| Muaj nuj nqi | Tshaj tawm |
| F-01 | Thawj tus nqi tswb |

3. Cov lus piav qhia ua haujlwm tshwj xeeb
Nkag mus khawmnkag mus rau tus password "1234", nias lub pobnkag mus rau cov ntawv qhia zaub mov, tam sim no cov ntawv qhia zaub mov yuav ntxiv P-01, A-01 thiab A-02.
P-01 Parameter rov qab
S-01: Restore Hoobkas nqis. Thaum lub sijhawm ua haujlwm, cov neeg siv tuaj yeem rov kho lub Hoobkas Chaw yog tias qhov ntsuas qhov ntsuas tsis zoo.
S-02: Lub Hoobkas calibration tiav.
A-01 / A-02Relay teeb tsa
Lub Rooj Tswjhwm Saib tsis tau tso tawm los ntawm ib qho relay, tus neeg siv tuaj yeem teeb tsa los ntawm A-01. Cov qauv ntawv qhia zaub mov yog qhia raws li hauv qab no
Tom qab nias khawmnkag mus rau A-01 ntawv qhia zaub mov, yuav tso saib F-01, nws yog Relay tso zis hom teeb, lub neej ntawd yog LE theem tso zis, nias khawmhloov PU, PU yog mem tes tso zis, Nias khawmtxuag, ces rov qab mus rau cov ntawv qhia zaub mov F-01. Nias khawmhloov cov ntawv qhia zaub mov, qhia F-02 yog lub sijhawm relay pulse tso zis, lub neej ntawd yog 3 vib nas this, tuaj yeem teem rau 3 ~ 9 vib nas this, nias khawmtxhawm rau txuag chaw tom qab ua tiav lub sijhawm nkag, nias lub pobtawm hauv qhov chaw.
Nco tseg: los ntawm lub neej ntawd, qhov ntsuas no tsuas yog nqa ib qho relay, thiab cov neeg siv tuaj yeem xaiv nqa ob lub relays. Lub sijhawm no, A-02 tau teeb tsa zoo, thiab txoj kev teeb tsa yog tib yam li A-01.
1. Rau cov phab ntsa-mounted combustible gas ntes lub tswb, thaum lub concentration ntawm combustible gas tshaj 100% LEL, lub kaw lus yuav cia li kaw lub hwj chim mov, kom lub detector nres ua hauj lwm thiab paub qhov tawg-pov thawj muaj nuj nqi. Lub sijhawm no, cov raj digital yuav ib txwm tso saib 100, ib txwm qhib qhov kawg ntawm lub relay txuas nrog, ob lub teeb-emitting diodes flicker, lub tswb nrov. Ntawm no, koj tuaj yeem nias khawm, lub kaw lus yuav cia li tawm hauv lub xeev kev tiv thaiv tshaj, tab sis yog tias cov roj concentration tseem siab heev, lub kaw lus yuav nyob twj ywm hauv lub xeev no. Koj tseem tuaj yeem tua lub hwj chim thiab tos kom cov roj concentration poob ua ntej hloov lub zog kom siv txuas ntxiv.
2. Tom qab thawj lub zog ntawm qhov ntsuas, lub sensor yuav muaj lub sijhawm polarization. Feem ntau, kuaj pom cov roj siv sijhawm ob peb feeb, lub sijhawm polarization ntawm TSIS TAU, HCL thiab lwm yam roj av kuj ntev. Tom qab lub polarization tiav lawm, cov zaub tus nqi yuav maj mam stabilize ntawm 0, thiab tom qab ntawd cov twj paj nruag tuaj yeem nkag mus rau hauv lub xeev kuaj pom.Thov xyuam xim rau tus neeg siv thaum siv.
Tswv yim: electrify lub sij hawm yuav tsum tau ntev dua nyob rau hauv lub caij ntuj no, yuav siv tau tom qab lub sensor kub tuaj.
Lub sijhawm lav ntawm cov cuab yeej ntsuas roj ua los ntawm kuv lub tuam txhab yog 12 lub hlis thiab lub sijhawm lav siv tau los ntawm hnub xa khoom. Cov neeg siv yuav tsum ua raws li cov lus qhia. Vim kev siv tsis raug, lossis kev ua haujlwm tsis zoo, qhov ntsuas kev puas tsuaj tshwm sim tsis nyob rau hauv qhov kev lees paub.
1. Ua ntej siv lub ntsuas, thov nyeem cov lus qhia kom zoo.
2. Kev siv cov cuab yeej siv yuav tsum ua raws li cov cai teev tseg hauv phau ntawv ua haujlwm.
3. Cov cuab yeej tu thiab hloov cov khoom yuav tsum tau ua los ntawm peb lub tuam txhab lossis ib ncig ntawm lub qhov.
4. Yog tias tus neeg siv tsis ua raws li cov lus qhia saum toj no los kho khau raj lossis hloov qhov chaw, kev ntseeg siab ntawm cov cuab yeej yuav tsum yog lub luag haujlwm ntawm tus neeg teb xov tooj.
5. Kev siv cov cuab yeej yuav tsum ua raws li cov tuam tsev hauv tsev thiab cov kev cai tswj xyuas cov khoom siv hauv lub hoobkas.
