Kev ua yuam kev thaum ua qhov kev teeb tsa ua haujlwm yuav ua rau lub cuab yeej puas thiab cov khoom siv txuas nrog.
Txhawm rau kom ntseeg tau kev sib cuag, zawm lub davhlau ya nyob twg screws nrog lub zog qhia hauv Table 1.
Thaum txo cov torque nruj, qhov chaw sib txuas yog rhuab, lub davhlau ya nyob twg thaiv yuav yaj thiab xaim tuaj yeem hlawv. Yog tias koj ua kom lub zog nruj, nws tuaj yeem muaj xov tsis ua haujlwm ntawm lub davhlau ya nyob twg thaiv screws lossis compression ntawm cov hlau txuas.
- Txuas lub cuab yeej raws li qhia hauv daim duab 2 (thaum siv lub cuab yeej hauv cov qauv ntsuas ntsuas analog) lossis raws li daim duab 3 (thaum siv lub cuab yeej nrog cov sensors digital). Lub roj teeb 12 V tuaj yeem siv los ua lub zog hluav taws xob.Supply voltage nyeem tau (tab.6
chaw nyob 7). Txhawm rau txuas lub cuab yeej mus rau ModBus network, siv CAT.1 lossis siab dua qub khub cable.
Nco tseg: Hu rau "A" yog rau kev sib kis ntawm lub teeb liab tsis hloov pauv, hu rau "B" yog rau lub teeb liab inverted. Lub hwj huam mov rau lub cuab yeej yuav tsum muaj kev sib cais galvanic los ntawm lub network. - Hloov lub zog ntawm lub cuab yeej.
CEEB TOOM: Cov zis relay hu rau "NO" yog "ib txwm qhib". Yog tias tsim nyog, nws tuaj yeem siv rau hauv kev teeb tsa thiab kev tswj hwm cov txheej txheem teev tseg los ntawm Tus Neeg Siv.
Siv lub cuab yeej
Tom qab lub hwj chim yog nyob rau, qhov taw qhia «» taws teeb. Qhov taw qhia
flashes rau 1.5 vib nas this. Tom qab ntawd cov ntsuas thiab «RS-485» teeb (daim duab 1, pos. 1, 2, 3) thiab tom qab 0.5 thib ob lawv tawm mus.
Txhawm rau hloov cov parameter koj xav tau:
- rub tawm OB-215/08-216 Control Panel program ntawm www.novatek-electro.com lossis lwm yam kev pabcuam uas tso cai rau koj ua haujlwm nrog Mod Bus RTU / ASCII raws tu qauv;
- txuas rau lub cuab yeej ntawm RS-485 interface; - ua qhov tsim nyog qhov chaw rau 08-215 tsis.
Thaum lub sij hawm sib pauv ntaub ntawv, qhov taw qhia "RS-485" flashes, txwv tsis pub lub "RS-485" qhov taw qhia tsis teeb.
Nco tseg: Thaum hloov 08-215 chaw, nws yog ib qho tsim nyog yuav tau txuag lawv rau flash nco los ntawm kev hais kom ua (xov 6, chaw nyob 50, tus nqi "Ox472C"). Thaum hloov ModBus nqis (table 3, chaw nyob 110 - 113) nws tseem yuav tsum tau rov pib dua lub cuab yeej.
Kev ua haujlwm MODES
Kev ntsuas hom
Hauv hom no, lub cuab yeej ntsuas qhov kev nyeem ntawm cov sensors txuas nrog cov khoom siv "101" lossis "102" (Daim duab 1, nws. 7), thiab nyob ntawm qhov chaw, ua cov haujlwm tsim nyog.
Interface Transformation hom
Hauv hom no, lub cuab yeej hloov cov ntaub ntawv tau txais los ntawm RS-485 interface (Mod tsheb npav RTU / ASCll) mus rau UART(TTL) lub ntsej muag (Table 2, chaw nyob 100, tus nqi "7"). Cov lus piav qhia ntxaws ntxiv pom hauv "Kev hloov pauv ntawm UART (TTL) cuam tshuam rau RS-485".
LUB CHAW UA HAUJ LWM
Pulse Counter
Txuas lub cuab yeej sab nraud raws li qhia hauv daim duab 2 (e). Teeb tsa lub cuab yeej rau kev ua haujlwm hauv Pulse Counter Mode (Table 2, chaw nyob 100, tus nqi "O").
Hauv hom no, cov cuab yeej suav cov naj npawb ntawm cov pulses ntawm cov tswv yim "102" (ntawm lub sijhawm tsis pub tsawg tshaj li tus nqi teev hauv Table 2 (chaw nyob 107, tus nqi hauv ms) thiab khaws cov ntaub ntawv hauv lub cim xeeb nrog lub sijhawm ntawm 1 feeb. Yog tias lub cuab yeej raug kaw ua ntej 1 feeb tau tas, tus nqi khaws cia zaum kawg yuav rov qab los thaum lub hwj chim.
Yog tias koj hloov tus nqi hauv daim ntawv teev npe (chaw nyob 108), tag nrho cov nqi khaws cia ntawm lub ntsuas pulse yuav raug muab tshem tawm.
Thaum tus nqi teev nyob rau hauv daim ntawv teev npe (chaw nyob 108) mus txog, lubcounteris incremented los ntawm ib tug (Table 6, chaw nyob 4:5).
Txhawm rau teeb tsa tus nqi pib ntawm lub ntsuas pulse nws yog ib qho tsim nyog yuav tsum tau sau cov nqi uas yuav tsum tau ua rau hauv daim ntawv teev npe (Table 6, chaw nyob 4: 5).
Logic Input/Pulse Relay
Thaum xaiv Logic Input/Pulse Relay hom (Table 2, Chaw Nyob 100, Tus Nqi 1), lossis hloov lub ntsuas pulse hom (Table 2, Chaw Nyob 106), yog tias cov neeg sib txuas tau raug kaw "C - TSIS MUAJ" (LED teeb tsa), lub cuab yeej yuav cia li qhib qhov "C - TSIS MUAJ" cov neeg sib cuag (LED tig tawm).
Logic Input Hom
Txuas lub cuab yeej raws li daim duab 2 (d). Teeb tsa lub cuab yeej rau kev ua haujlwm hauv Logic Input / Pulse Relay Hom (Table 2, chaw nyob 100, tus nqi 1′), teeb tsa cov mem tes suav hom (Table 2, chaw nyob 106, tus nqi “2”).
