Kuyika

1. Chigawochi chiyenera kukhazikitsidwa ndi katswiri woyenerera malinga ndi malangizo operekedwa ndi miyezo yamakampani.
2. Onetsetsani kukhazikitsa ndi kukhazikitsa koyenera kutengera ntchito ndi chilengedwe.

Ntchito

1. Ogwira ntchito ayenera kudziwa malamulo amakampani ndi miyezo yoyendetsera ntchito yotetezeka.
2. Chigawochi chimapereka ntchito za alamu ngati zatha, koma sizithetsa zomwe zimayambitsa.

Kusamalira

1. Zomverera ziyenera kuyesedwa chaka chilichonse kuti zigwirizane ndi malamulo. Tsatirani njira yoyeserera yoyeserera ngati malamulo akumaloko safotokoza.
2. Pambuyo pakutha kwa gasi wambiri, yang'anani ndikusintha masensa ngati kuli kofunikira. Tsatirani zoyesa ndi kuyesa zomwe mukufuna.

Technician ntchito kokha!

• Chigawochi chiyenera kukhazikitsidwa ndi katswiri wodziwa bwino ntchito yemwe adzayike chipangizochi motsatira malangizowa komanso mfundo zomwe zakhazikitsidwa m'dziko lawo.
• Ogwira ntchito moyenerera a bungweli ayenera kudziwa malamulo ndi miyezo yokhazikitsidwa ndi mafakitale/dziko lawo pakugwira ntchito kwa gawoli.
• Zolembazi zimangopangidwa ngati kalozera ndipo wopanga alibe udindo wokhazikitsa kapena kugwiritsa ntchito chipangizochi.
• Kulephera kukhazikitsa ndi kugwiritsa ntchito chipangizochi motsatira malangizowa komanso malangizo amakampani kungayambitse kuvulala kwakukulu kuphatikiza imfa ndipo wopanga sadzakhala ndi mlandu pankhaniyi.
• Ndi udindo wa okhazikitsa kuti awonetsetse mokwanira kuti zidazo zayikidwa bwino ndikukhazikitsidwa molingana ndi chilengedwe komanso momwe zinthuzo zikugwiritsidwa ntchito.
• Chonde dziwani kuti Danfoss GD ili ndi chilolezo ngati chipangizo chotetezera. Ngati kutayikira kumachitika GD adzapereka alamu ntchito zida olumikizidwa (PLC kapena BMS machitidwe), koma si kuthetsa kapena kusamalira kutayikira muzu chifukwa palokha.

Mayeso a Chaka
Kuti mugwirizane ndi zofunikira za EN378 ndi F GAS regulation sensors ziyenera kuyesedwa chaka chilichonse. Komabe malamulo amderali angatchule mtundu ndi kuchuluka kwa mayesowa. Ngati sichoncho njira yoyeserera ya Danfoss iyenera kutsatiridwa. Lumikizanani ndi Danfoss kuti mumve zambiri.

• Pambuyo pokhudzana ndi kutayikira kwamphamvu kwa gasi, sensor iyenera kuyang'aniridwa ndikusinthidwa ngati kuli kofunikira. Yang'anani malamulo am'deralo okhudza kuwerengetsa kapena zoyeserera.

Kulumikiza GD ku Danfoss monitoring system (mkuyu 8 ndi 9)

• Wiring (mkuyu 8)
• GD yonse iyenera kulumikizidwa AA, BB,
• COM - COM (chithunzi)
• Mukalumikizana ndi gulu lowunikira la Danfoss ma terminal omwewo amalumikizidwa wina ndi mnzake mwachitsanzo AA, BB, Com - Com.
• Pa njira yomaliza yowunikira ya GD ndi Danfoss, konzani chopinga cha 120 ohm kudutsa terminal A ndi B kuti muthetse njira yolumikizirana.
• Kuchuluka kwa 31 GDs kumatha kulumikizidwa. Ngati mayunitsi opitilira 31 akufunika, chonde lemberani Danfoss kuti mudziwe zambiri.GD adilesi (mku. 9)
• Adilesi ya sensa imayikidwa ndi S2 ndi S3, kusintha ma dials awa pakati pa 0 ndi F kudzapatsa sensor adilesi yake monga momwe g. 9. Tchati chosinthira pakati pa manambala a njira ya Danfoss yowunika ndi adilesi ya hexadecimal ya GD yalumikizidwa. Mphamvu ziyenera kuchotsedwa poyika ma adilesi pa GD.

Mayeso a Chaka

• Kuti mugwirizane ndi zofunikira za EN378 ndi malamulo a F GAS, masensa ayenera kuyesedwa chaka chilichonse. Howe, ve,r malamulo amderali atha kufotokoza mtundu ndi kuchuluka kwa mayesowa. Ngati sichoncho, njira yoyeserera ya Danfos iyenera kutsatiridwa. Lumikizanani ndi Danfoss kuti mumve zambiri.
• Pambuyo pokhudzana ndi kutayikira kwamphamvu kwa gasi, sensor iyenera kuyang'aniridwa ndikusinthidwa ngati kuli kofunikira.
• Yang'anani malamulo am'deralo okhudza kuwerengetsa kapena zoyeserera.

1. Gwiritsani ntchito voliyumu nthawi zonsetage 0-10 V kuti muwone zomwe zatuluka kuti zikhazikike.
2. GDC IR imabwereranso ku 400 ppm, popeza uwu ndi mulingo wabwinobwino wa mpweya. (~4.6 mA/~0.4 V/ 0.2 V)
3. Ngati GD yakhala ikusungidwa kwa nthawi yayitali kapena yazimitsidwa kwa nthawi yayitali, kukhazikika kudzakhala pang'onopang'ono. Komabe mkati mwa maola 1-2 mitundu yonse ya GD iyenera kuti yatsikira pansi pa alamu otsika ndikugwira ntchito.
4. Kupita patsogolo kumatha kuyang'aniridwa ndendende pazomwe 0 10VV imatulutsa. Pamene zotulukazo zimakhala pafupi ndi zero (400 ppm pa nkhani ya masensa a IR CO2), GD imakhazikika. Muzochitika zapadera, makamaka ndi sensa ya CT, ntchitoyi imatha kutenga maola 30.

Danfoss sangavomereze chilichonse cha zolakwika zomwe zingachitike m'mabuku, timabuku, ndi zolemba zina. Danfoss ali ndi ufulu wosintha zinthu zake popanda kuzindikira. Izi zikugwiranso ntchito pazinthu zomwe zaperekedwa kale, malinga ngati zosinthazo zitha kupangidwa ndikusintha kotsatira kukhala kofunikira pazogwirizana kale. Zizindikiro zomwe zili m'nkhaniyi ndi katundu wamakampani omwe akukhudzidwa. Danfoss ndi Danfoss logotype ndi zilembo za Danfoss A/S. Maumwini onse ndi otetezedwa

FAQS

Q: Ndiyenera kuchita chiyani pakatuluka mpweya?
A: Yang'anani ndikusintha masensa ngati kuli kofunikira ndikutsata malamulo am'deralo kuti ayese ndi kuyesa.

Q: Kodi masensa ayenera kuyesedwa kangati?
A: Zomverera ziyenera kuyesedwa chaka chilichonse kuti zigwirizane ndi malamulo. Malamulo amderali angatchule ma frequency osiyanasiyana oyesa.
