HK INSTRUMENTS DPT-Ctrl-MOD Air Handling Controller Manual

MAU OYAMBA

Zikomo posankha chowongolera cha HK Instruments DPT-Ctrl-MOD chokhala ndi mphamvu yosiyanitsira kapena cholumikizira mpweya. Owongolera a PID a DPTCtrl-MOD adapangidwa kuti azipanga zokha pamakampani a HVAC/R. Ndi wowongolera womangidwa wa DPT-Ctrl-MOD ndizotheka kuwongolera kuthamanga kosalekeza kapena kuyenda kwa mafani, machitidwe a VAV kapena d.ampizi. Mukawongolera kayendedwe ka mpweya, ndizotheka kusankha wopanga mafani kapena kafukufuku wamba woyezera yemwe ali ndi mtengo wa K.

DPT-Ctrl-MOD imaphatikizapo malo olowetsamo omwe amathandizira kuwerenga ma siginecha angapo monga kutentha kapena kuwongolera kuwongolera pa Modbus. Malo Olowetsamo ali ndi njira imodzi yolowera yopangidwa kuti ivomereze chizindikiro cha 0−10 V, NTC10k, Pt1000, Ni1000/(-LG), ndi BIN IN (chizindikiro chaulere).

APPLICATIONS

Zipangizo zamtundu wa DPT-Ctrl-MOD zimagwiritsidwa ntchito kwambiri pamakina a HVAC/R a:

CHOCHITA 4: KUSINTHA ZIRO POINT

ZINDIKIRANI! Nthawi zonse ziro chipangizo musanagwiritse ntchito. 

Wonjezerani voltage iyenera kulumikizidwa ola limodzi isanayambe kusintha kwa zero. Pezani kudzera pa Modbus kapena kukankha batani.

1. Masulani machubu onse kuchokera ku zolowetsa zokakamiza + ndi -.
2. Yambitsani menyu ya chipangizocho ndikukankhira batani losankha kwa masekondi awiri.
3. Sankhani Zero sensor podina batani losankha.
   
4. Yembekezerani mpaka LED izimitse ndikuyikanso machubu kuti mulowetsenso.

CHOCHITA 5: KUSINTHA ZINTHU ZOSINKHA

Zizindikiro zolowetsa zimatha kuwerengedwa pa Modbus kudzera pa mawonekedwe a DPT-MOD RS485.

Zizindikiro	Kulondola kwa kuyeza	Kusamvana
0 V	<0,5%	0,1%
NTC10K	<0,5%	0,1%
pt1000	<0,5%	0,1%
Ni1000/(-LG)	<0,5%	0,1%
BIN IN (kulumikizana kwaulere)	/	/

Ma jumpers ayenera kukhazikitsidwa motsatira malangizo omwe ali pansipa ndi mtengo wake
ziyenera kuwerengedwa kuchokera m'kaundula yoyenera.

CHOCHITA 6: KULIPITSA NTCHITO

Chipangizocho chimaphatikizapo ntchito yolipirira kutentha kwakunja yomwe imatha kuthandizidwa kuchokera pamenyu. Ikatsegulidwa ndipo cholumikizira chakunja cha kutentha chikuphatikizidwa, malo okhazikika a chipangizocho adzasinthidwa kuti apereke chiwongola dzanja chakunja kwa mpweya wozizira. Izi zitha kupulumutsa mphamvu. kwa mpweya wozizira wakunja. Izi zitha kupulumutsa mphamvu.

Ngati chipukuta misozi chiyatsidwa, chipangizocho chidzachepetsa kuchepa
malo ogwiritsira ntchito (REF FLOW/REF PRESSURE) ndi 0 % mpaka TC DROP % kuchokera ku TC START TE mpaka TC STOP TE.

Chipangizochi chimakhazikitsa +5 ° C kusiyana pakati pa kutentha koyambira ndi kuyimitsa. Kutentha koyambira kuyenera kukhala kokwera kuposa kutentha koyimitsa.

1. Lumikizani ndikusintha sensor yakunja ya kutentha kwa mpweya. Onani sitepe 5.
2. Yambitsani kubweza kutentha.
   
3. Khazikitsani kutentha koyambira kuti mubweze
   
4. Khazikitsani kutentha koyimitsa kuti mubweze.
   
5. Khazikitsani kutsika kwakukulutage za malipiro.
   

CHOCHITA 7: Kutulutsa kokhazikika

Zikhazikiko zotuluka zokhazikika zitha kuthandizidwa kuti zikhazikitse zowongolera pamtengo wokonzedweratu. Cholinga chachikulu cha ntchitoyi ndikupangitsa kusintha kwa ma valve ndi ma terminals popanda DPT-Ctrl kukhudza kuthamanga kwa duct kapena kutuluka kwa mpweya. Ikhozanso kukuthandizani kuthetsa vuto la kukhazikitsa.

1. Kuti muthe kutulutsa kokhazikika, yendetsani pamalo ake pa menyu
   
2. Dinani batani losankha ndikusankha mtengo womwe mukufuna. Zotulukapo tsopano zikhalabe pamtengo uwu mpaka kalekale. M'njira yodziwika bwino (yomwe ili pansipa), mzere wapamwamba wa zowonetsera uwonetsa ZOKHUDZA xx% kusonyeza kuti zomwe zatuluka zakhazikika.
   
3. Kuti muwongolere kutulutsa kwanthawi zonse ndikuyimitsa zomwe mwakhazikika, yendani pamalo ake, sankhani ndikuyika mtengo kuti ZIMENE.
   Fixed output function imapezekanso kudzera pa Modbus. (4 × 0016: Overdrive ikugwira ntchito, 4 × 0015: Mtengo wa overdrive)

CHOCHITA 8: Kugwiritsa ntchito mawonekedwe a 2SP

2SP (setpoint) ndi gawo lomwe lili ndi zolowetsa zamabina kuti musankhe pakati pa magawo awiri osinthika ogwiritsa ntchito. Malo omwe mukufuna akhoza kusankhidwa, mwachitsanzoample, ndi wotchi ya mlungu ndi mlungu, tembenuzani sinthani kapena kusinthana kwa kiyi ya kiyi.

1. Sankhani INPUT => BIN IN.
   
2. Khazikitsani ma jumpers monga momwe zasonyezedwera pambali kuti mudziwe chizindikiro cholowera.

MFUNDO YOTHANDIZA

Wogulitsa ali ndi udindo wopereka chitsimikizo cha zaka zisanu pa katundu woperekedwa ponena za zinthu ndi kupanga. Nthawi ya chitsimikizo imaganiziridwa kuti ikuyamba pa tsiku loperekera mankhwala. Ngati chilema cha zida zopangira kapena cholakwika chapezeka, wogulitsa ali ndi udindo, pomwe katunduyo atumizidwa kwa wogulitsa mosazengereza kapena chitsimikiziro chisanathe, kuti akonze cholakwikacho mwakufuna kwake mwina pokonzanso cholakwikacho. kapena popereka kwaulere kwa wogula katundu watsopano wopanda cholakwika ndikutumiza kwa wogula. Ndalama zobweretsera zokonzanso pansi pa chitsimikizo zidzalipidwa ndi wogula ndi ndalama zobwezera ndi wogulitsa. Chitsimikizo sichimaphatikizapo zowonongeka zomwe zimachitika chifukwa cha ngozi, mphezi, kusefukira kwa madzi kapena zochitika zina zachilengedwe, kuvala kwachibadwa, kugwiritsira ntchito molakwika kapena mosasamala, kugwiritsa ntchito molakwika, kulemetsa, kusungirako kosayenera, kusamalidwa kolakwika kapena kumanganso, kapena kusintha ndi kuyika ntchito zomwe sizinachitike ndi wogulitsa. Kusankhidwa kwa zida za zida zomwe zimatha kuwonongeka ndiudindo wa wogula, pokhapokha atagwirizana mwalamulo. Ngati wopanga asintha mawonekedwe a chipangizocho, wogulitsa sakakamizidwa kupanga zofananira ndi zida zomwe zidagulidwa kale. Kudandaula chifukwa cha chitsimikizo kumafuna kuti wogulayo wakwaniritsa bwino ntchito zake zomwe zinachokera pakupereka ndi zomwe zanenedwa mu mgwirizano. Wogulitsayo adzapereka chitsimikizo chatsopano cha katundu yemwe wasinthidwa kapena kukonzedwa mkati mwa chitsimikizo, komabe pokhapokha patatha nthawi ya chitsimikizo cha mankhwala oyambirira. Chitsimikizocho chimaphatikizapo kukonza gawo kapena chipangizo chomwe chili ndi vuto, kapena ngati pakufunika, gawo kapena chipangizo chatsopano, koma osati kuyika kapena kusinthanitsa ndalama. Mulimonse momwe zingakhalire, wogulitsa ali ndi udindo wolipira chiwongola dzanja cha kuwonongeka kosalunjika.
