I-HK INDLELA I-DPT-Ctrl-MOD yoMyalelo woMyalelo woLawulo loMoya

INTSHAYELELO

Enkosi ngokukhetha i-HK Instruments DPT-Ctrl-MOD isilawuli esiphathwayo somoya kunye noxinzelelo olwahlukileyo okanye ukuhambisa umoya. Uluhlu lwe-DPTCtrl-MOD abalawuli be-PID benzelwe ukwakha i-automation kwishishini le-HVAC / R. Ngomlawuli owakhelwe ngaphakathi we-DPT-Ctrl-MOD kunokwenzeka ukulawula uxinzelelo oluqhubekayo okanye ukuhamba kwabalandeli, iinkqubo ze-VAV okanye i-dampers. Xa ulawula ukuhamba komoya, kuyenzeka ukuba ukhethe umenzi wefeni okanye iprobe yokulinganisa eqhelekileyo enexabiso le-K.

I-DPT-Ctrl-MOD ibandakanya i-terminal ye-Input eyenza ukufundwa kweempawu ezininzi ezifana nobushushu okanye ukuhanjiswa kolawulo kwi-Modbus. I-terminal ye-Input inejelo lokufaka elinye elenzelwe ukwamkela u-0−10 V, NTC10k, Pt1000, Ni1000/(-LG), kunye ne-BIN IN (uqhagamshelwano olunokwenzeka lwasimahla).

UKURECYCATION/UKULAHLWA

Amalungu ashiyekileyo kufakelo kufuneka aphinde asetyenziswe ngokwemiyalelo yendawo yakho. Izixhobo ezingagunyaziswanga kufuneka zisiwe kwindawo yokurisayikilisha egxile kwinkunkuma yombane.

UMGAQO-NKQUBO WEWARANTI

Umthengisi ubophelelekile ukuba abonelele ngewaranti yeminyaka emihlanu yeempahla ezizisiweyo malunga nemathiriyeli kunye nokuveliswa. Ixesha lewaranti lithathwa ukuba liqale ngomhla wokuhanjiswa kwemveliso. Ukuba isiphene kwizinto eziluhlaza okanye isiphene sokuvelisa sifunyenwe, umthengisi ubophelelekile, xa imveliso ithunyelwa kumthengisi ngaphandle kokulibazisa okanye ngaphambi kokuphela kwewaranti, ukulungisa impazamo ngokubona kwakhe mhlawumbi ngokulungisa imveliso eneziphene. okanye ngokuzisa simahla kumthengi imveliso entsha engenasiphako aze ayithumele kumthengi. Iindleko zokuthumela ukulungiswa phantsi kwewaranti ziya kuhlawulwa ngumthengi kunye neendleko zokubuyisela ngumthengisi. Iwaranti ayibandakanyi umonakalo obangelwe yingozi, umbane, izandyondyo zemvula okanye ezinye izinto zendalo, ukunxiba okuqhelekileyo kunye nokukrazula, ukuphathwa ngokungafanelekanga okanye ukungakhathali, ukusetyenziswa okungaqhelekanga, ukulayisha, ukugcinwa okungafanelekanga, ukhathalelo olungachanekanga okanye ukwakhiwa ngokutsha, okanye utshintsho kunye nomsebenzi wofakelo ongenziwanga umthengisi. Ukukhethwa kwezixhobo zezixhobo ezithanda ukubola luxanduva lomthengi, ngaphandle kokuba kuvunyelwene ngokusemthethweni. Ukuba umenzi utshintshe ubume besixhobo, umthengisi akanyanzelekanga ukuba enze utshintsho oluthelekisayo nezixhobo esele zithengiwe. Ukufaka isibheno sewaranti kufuna ukuba umthengi uye wazalisekisa ngokuchanekileyo imisebenzi yakhe evela ekuhanjisweni kwaye echazwe kwimvumelwano. Umthengisi uya kunika iwaranti entsha yeempahla eziye zatshintshwa okanye zalungiswa ngaphakathi kwewaranti, nangona kunjalo kuphela ekupheleni kwexesha lewaranti yemveliso yokuqala. Iwaranti ibandakanya ukulungiswa kwenxalenye enesiphene okanye isixhobo, okanye ukuba kuyimfuneko, inxalenye entsha okanye isixhobo, kodwa hayi ukufakela okanye ukutshintshiselana ngeendleko. Naphantsi kwayo nayiphi na imeko umthengisi unoxanduva lokuhlawula umonakalo ngenxa yomonakalo ongathanga ngqo.
