Ukusethwa kokulawula komyalelo womsebenzisi mA okukhiphayo kwe-PID
Lungiselela isilawuli se-PID esiphumayo se-mA
Qiniseka ukuthi imojuli yokukhipha engu-4-20 mA ifakiwe kusilawuli se-SC45001. Bheka amadokhumenti anikezwe nemojula. Qiniseka ukuthi zonke izixhumo zikagesi ezidingekayo ziqediwe ngaphambi kokuthi kulungiswe ukuphuma kwe-4-20 mA.
- Thola ukuhlobana phakathi kokokufaka kwamanje kanye nevelu ebaliwe ngale ndlela elandelayo:
- Khomba ukuthi yiliphi ibanga lokuphumayo kwe-analog esebenzisa idivayisi exhunyiwe (0-20 mA noma 4-20 mA).
- Khomba inani eliphakeme elilingana no-20 mA ekukhishweni kwe-analog.
- Khomba inani elincane elilingana no-0 noma 4 mA ekukhishweni kwe-analog.
- Cindezela isithonjana semenyu enkulu, bese ukhetha Okukhiphayo > Okuphumayo kwe-mA > Ukusethwa kwesistimu.
- Iziteshi ezitholakalayo ezisekelwe kumamojula wokunweba afakiwe ziyaboniswa.
- Faka izilungiselelo zesiteshi ngasinye.
Incazelo Yenketho
- Umthombo Ikhetha okukhiphayo kwe-analog okuzolungiswa. Kudivayisi ekhethiwe, khetha ipharamitha esetha izinketho zokulinganisa.
- Ipharamitha Ishintsha ipharamitha ekhethiwe kunketho yomthombo.
- Idatha view Isetha inani elilinganisiwe elibonakala kusibonisi futhi lilondolozwe kulogi yedatha. Izinketho: Inani lokokufaka (okuzenzakalelayo) noma Okwamanje.
- Umsebenzi Isetha umsebenzi wokuphumayo. Izinketho zokusetha ziyashintsha ngokusekelwe kumsebenzi okhethiwe.
- Ukulawulwa komugqa—Isiginali incike ngokomugqa enanini lenqubo. Bheka i-SC4500 User Manual.
- Ukulawulwa kwe-PID-Isiginali isebenza njengesilawuli se-PID (Esilinganiselayo, Esihlanganisiwe noma Esiphuma Kunye).
- Ukudlulisar Isetha inani lokudlulisa eliboniswa kokuphumayo kwe-analogi lapho umthombo okhethiwe ubika iphutha langaphakathi, unqanyulwa ohlelweni noma imodi yayo yokukhipha isethwe kokuthi Dlulisa. Okuzenzakalelayo: 10 mA
- Okwamanje Ibonisa okukhiphayo okubaliwe kwamanje (ku-mA).
- Idatha isikhawu somgawuli
- Amasethi isikhawu lapho inani elibonisiwe ligcinwa khona kusilondolozi sedatha. Izinketho: KUVALIWE (okuzenzakalelayo), imizuzu emi-5, imizuzu eyi-10, imizuzu eyi-15, imizuzu engama-20 noma engama-30
Qedela izilungiselelo ngokusekelwe kuzilungiselelo Zomsebenzi.
Umsebenzi wokulawula we-PID
Incazelo Yenketho
- Imodi yephutha Isetha okukhiphayo kwe-analogi kumisiwe noma kunani lokudlulisa lapho kwenzeka iphutha langaphakathi. Izinketho: Bamba noma Dlulisela
- Amasethi emodi isimo sokuphumayo lapho inani lenqubo lingaphandle kwebhande elilawulwayo2.
- Ukulawula okuqondile- Okukhiphayo kwe-mA kuzokwehla njengoba ukuguquguquka kwenqubo kukhuphuka
- Reverse- Okukhiphayo kwe-mA kuzokhula njengoba ukuguquguquka kwenqubo kukhuphuka
- Imodi ezenzakalelayo-Okukhiphayo kusebenza njengesilawuli se-PID. I-SC4500 Controller ibheka ukuguquguquka kwenqubo futhi ilungisa i-0-20 mA ngokuzenzakalelayo.
- Imanuwali—I-PID ivaliwe. Okukhiphayo kulungiswa njengokusethwe kokuthi Okukhiphayo Mathupha.
- Okukhiphayo mathupha Ukwengeza inani lamanje eliphumayo lingasethwa (isimo: Imodi isethwe ukuze ithi Manuwali). Okukhiphayo okwamanje
- inani kufanele be ngaphakathi kwamanani asethwe kumamenyu Okuncane kanye Naphezulu.
- Isilawuli se-SC200 sinezilungiselelo ezihlukile ze-PID.
- Lokhu kuziphatha kwehlukile ekuphathweni okuvamile kwe-PID nesilawuli se-SC200
Incazelo Yenketho
- Ubuncane Isetha umkhawulo ophansi wokukhiphayo kwamanje. Okuzenzakalelayo: 0.0 mA
- Ubuningi Isetha umkhawulo ophezulu wevelu engaba khona yokuphumayo. Okuzenzakalelayo: 20.0 mA
- I-Relay setpoint Inani lenqubo efiselekayo. Isilawuli se-PID sizama ukulungisa leli nani lenqubo.
- Ufile indawo I-dead zone iyibhande elizungeze i-setpoint. Kuleli bhendi isilawuli se-PID asishintshi isignali yokuphumayo. Le bhendi inqunywa njenge-setpoint ± indawo efile. Indawo efile iqinisa uhlelo olulawulwa yi-PID, oluthambekele ekunyakazeni. Kunconywa ukusetha ingxenye ku-0 (okuzenzakalelayo).
- Ngokulinganayo Isetha ingxenye elinganayo yesilawuli se-PID.
- I-proportional ingxenye yesilawuli ikhiqiza isignali yokuphumayo encike ngokomugqa ekuchezukeni kokulawula. Ingxenye ephezulu ye-proportional isabela ngokushesha kunoma yiziphi izinguquko kokokufaka kodwa iqala ukunyakazisa kalula uma inani lisethelwe phezulu. Ingxenye elinganayo ayikwazi ukunxephezela ngokuphelele ukuphazamiseka.
- Example: Igama lephutha (umehluko phakathi kwe-setpoint kanye nevelu yenqubo) ngu-2 futhi inzuzo elinganiselwe ingu-5, bese inani lamanje eliphumayo lingu-10 mA.
- Okuphelele Isetha ingxenye yokuhlanganisa yesilawuli se-PID.
- I ingxenye ebalulekile yesilawuli ikhiqiza isignali yokuphumayo ekhuphuka ngokomugqa lapho ukuchezuka kokulawula kuhlala njalo. Ingxenye ebalulekile iphendula kancane kunengxenye ye-proportional futhi ingaba ngokuphelele
- nxephezela iziphazamiso. Lapho ingxenye yokuhlanganisa iphezulu, iphendula kancane. Uma ingxenye yokuhlanganisa isethelwe phansi, iqala ukuguquka.
- Ngoba ukusetshenziswa kwe-SC4500 PID, ungasethi ingxenye yokuhlanganisa ibe ngu-0. Ukusetha okunconyiwe kwengxenye yokuhlanganisa imizuzu eyi-10.
- Okuphuma kokunye Isetha ingxenye ephuma kokunye yesilawuli se-PID.
- Okuphuma kokunye ingxenye yesilawuli se-PID ikhiqiza isignali yokuphumayo encike ekushintsheni kokuchezuka kokulawula. Lapho ukuchezuka kokulawula kushintsha ngokushesha, kulapho isignali yokuphumayo iba phezulu. Ingxenye ephuma kokunye idala isignali yokuphumayo inqobo nje uma ukuchezuka kokulawula kushintsha.
- Uma ekhona akulona ulwazi mayelana nokuziphatha kwenqubo elawulwayo, kunconywa ukuthi usethe le ngxenye ku-"0", ngoba le ngxenye ijwayele ukuzulazula kakhulu.
- Snap shot Ibonisa inani lamanje lokufakwayo le-PID (inani lenqubo).
- Okwamanje Ibonisa inani lamanje lokuphumayo le-PID.
- Cindezela isithonjana semenyu enkulu, bese ukhetha Okukhiphayo > Okukhiphayo kwe-mA > Ukuhlola/Ukulungisa.
Imenyu Yokuhlola/Yokulungisa ivumela umsebenzisi ukuthi ahlole ipulaki yangaphakathi kumakhadi okunweba. - Khetha inketho.
Incazelo Yenketho
- Ukuhlolwa komsebenzi Ihlola okuphumayo kumojuli ekhethiwe.
- Isimo sokukhiphayo Ibonisa isimo semiphumela kumojuli ekhethiwe.
Ukulungiswa kwe-PID
- Faka i-setpoint, imodi kanye nengxenye yokulinganisa.
- Setha ingxenye yokuhlanganisa ibe imizuzu eyi-10 bese ingxenye ephuma kokunye ibe ngu-0.
- Gada inani lenqubo futhi ukhombe ukuthi singakanani isikhathi nokuthi isilawuli se-SC4500 siseduze kangakanani singathola inqubo endaweni yokubeka.
- Lapho umsebenzisi azi ukuthi Isilawuli se-SC4500 sisabela kanjani ezinguqukweni zenqubo, buyekeza ingxenye yokuhlanganisa futhi uhlonze ukuthi inqubo isabela kanjani.
- Ukuze uthole ukusabela okusheshayo kusukela kunqubo, khulisa ingxenye elinganayo kanye/noma yehlisa ingxenye yokuhlanganisa.
- Lapho okukhiphayo kushintsha phakathi kuka-4 mA no-20 mA, inqubo iyahamba. Inqubo kumele isabele kancane.
- Nciphisa ingxenye elinganayo kanye/noma ukhuphule ingxenye yokuhlanganisa ukuze uvimbele ukuzungeza.
- Kunconywa ukwenza ushintsho olulodwa ngesikhathi, bese uqapha ukuthi inqubo isabela kanjani kushintsho ngalunye.
Umfanekiso 1 ukushuna kwe-PID nge-setpoint ku-15
