• Yog tias lwm hom roj sensor txuas nrog, koj yuav tsum kho lawv nrog cov cuab yeej conÿguration, vim tias lwm yam khoom siv yuav teb nrog cov lus yuam kev.
• Qhov no feature nce tus neeg siv thiab kev khiav hauj lwm kev ruaj ntseg.
• Cov sensors tshiab yeej ib txwm xa lub Hoobkas-calibrated los ntawm Danfoss. Qhov no yog sau los ntawm calibration daim ntawv qhia hnub thiab calibration gas.
• Kev rov ntsuas dua tsis tsim nyog thaum lub sijhawm ua haujlwm yog tias lub cuab yeej tseem nyob hauv nws qhov qub ntim (cua nruj tiv thaiv los ntawm lub hau liab tiv thaiv) thiab qhov ntsuas tsis tau rov qab ntau dua 12 lub hlis.

Kev xeem ua haujlwm (rau kev ua haujlwm pib thiab kev saib xyuas)

• Kev ntsuas kev ua haujlwm yuav tsum tau ua thaum txhua qhov kev pabcuam, tab sis tsawg kawg ib xyoos ib zaug.
• Kev sim ua haujlwm yog ua tiav los ntawm nias lub pob xeem rau ntau tshaj 20 sec thiab saib xyuas tag nrho cov khoom sib txuas (Buzzer, LED, Relay txuas nrog) ua haujlwm zoo. Tom qab deactivation, tag nrho cov zis yuav tsum cia li rov qab mus rau lawv qhov chaw pib.
• Zero-point test nrog huab cua sab nraum zoov
• Zero-point test nrog huab cua sab nraum zoov. (Yog tias tau teev tseg los ntawm cov kev cai hauv zos) Lub peev xwm zero o˛set tuaj yeem nyeem tau los ntawm kev siv cov cuab yeej Pabcuam.

Kev sim mus ncig nrog kev siv roj (yog tias muaj raws li kev cai hauv zos)

• Lub sensor yog gassed nrog siv roj (rau qhov no, koj xav tau ib lub raj mis roj nrog lub siab regulator thiab calibration adapter).
• Thaum ua li ntawd, lub tswb ceeb toom tau dhau mus, thiab tag nrho cov khoom tso tawm tau qhib. Nws yog ib qho tsim nyog yuav tsum xyuas seb qhov kev sib txuas ua haujlwm puas ua haujlwm raug (lub suab nrov, kiv cua hloov mus, thiab cov cuab yeej kaw). Los ntawm nias lub laub khawm ntawm lub horn, lub horn lees paub yuav tsum tau kuaj xyuas
• . Tom qab tshem tawm cov khoom siv roj, tag nrho cov zis yuav tsum tau rov qab mus rau lawv qhov chaw pib.
• Ntxiv rau qhov kev sim ua haujlwm yooj yim, nws tseem tuaj yeem ua qhov kev sim ua haujlwm siv calibration. Yog xav paub ntxiv, thov mus saib Phau Ntawv Qhia Tus Neeg Siv.

Controller Unit ntau GDU commissioning

Rau kev ua haujlwm nrawm thiab xis nyob peb pom zoo ua raws li hauv qab no. Tshwj xeeb tshaj yog cov kev qhia tshwj xeeb ntawm ÿeld tsheb npav cable yuav tsum tau kuaj xyuas kom zoo, vim tias nws nyob ntawm no qhov twg feem ntau ua rau muaj teeb meem hauv kev sib txuas lus hauv tsheb npav ÿeld.

Optical Check

• Hom kab yog siv (JY(St)Y 2x2x0.8LG lossis zoo dua).
• Cable topology thiab cable ntev.
• Kho qhov siab mounting ntawm cov sensors
• Kev sib txuas raug ntawm txhua GDU raws li ÿg 8
• Kev txiav tawm nrog 560 ohms thaum pib thiab qhov kawg ntawm txhua ntu.
• Ua tib zoo saib xyuas kom cov polarities ntawm BUS_A thiab BUS_B tsis thim rov qab!

Tshawb xyuas luv luv / cuam tshuam / Cable Length ntawm Field Bus (saib ÿg8.1)

• Cov txheej txheem no yuav tsum tau ua rau txhua ntu.
• Lub tsheb npav ÿeld yuav tsum tau muab tso rau ntawm qhov txuas txuas txuas ntawm GDU rau qhov kev sim no. Lub plug, txawm li cas los xij, tseem tsis tau ntsaws rau hauv GDU.

Tshem tawm cov tsheb npav ÿeld coj los ntawm Controller Unit central control. Txuas lub ohmmeter mus rau xoob leads thiab ntsuas tag nrho lub voj tsis kam. See yg. 8.1 Tag nrho lub voj tsis kam yog xam raws li hauv qab no:

• R (tag nrho) = R (cable) + 560 Ohm (txiav tsis kam)
• R (cable) = 72 Ohm/km (loop resistance) (cable type JY(St)Y 2x2x0.8LG)

R (tag nrho) (ohm)	Ua rau	Kev daws teeb meem
<560	Luv-circuit	Nrhiav ib lub voj voog luv luv hauv lub tsheb npav cable.
tsis kawg	Qhib-circuit	Nrhiav qhov cuam tshuam hauv lub tsheb npav hauv teb chaws.
> 560 < 640	Cable yog ok	—

Qhov kev tso cai cable ntev tuaj yeem suav nrog txoj hauv kev txaus raws li cov qauv hauv qab no.

• Tag nrho cable ntev (km) = (R (tag nrho) - 560 Ohm) / 72 Ohm
• Yog hais tias lub tsheb npav ÿeld yog OK, rov txuas nws mus rau lub hauv paus.

Txheeb Voltage thiab Bus Polarity ntawm Field Bus (saib ÿg 8.2 thiab 8.3)

• Lub tsheb npav txuas yuav tsum tau ntsaws rau hauv txhua GDU.
• Hloov lub operating voltage nyob rau ntawm Controller Unit central unit.
• Lub teeb ntsuab LED ntawm GDU teeb tsis muaj zog thaum ua haujlwm voltage yog siv (voltage qhov taw qhia).
• Check kev khiav hauj lwm voltage thiab tsheb npav polarity ntawm txhua GDU raws li ÿg. 7.1 thiab 7.2. Umin = 16 V DC (20 V DC rau Heavy Duty)

Bus polarity:
Ntsuas qhov nro BUS_A tawm tsam 0 V DC thiab BUS_B tawm tsam 0 V DC. U BUS_A = ca. 0.5 V > U BUS_B
U BUS_B = ca. 2 - 4 V DC (nyob ntawm tus naj npawb ntawm GDU thiab qhov ntev cable)

Hais txog GDU

• Tom qab kuaj xyuas lub tsheb npav ÿeld ua tiav, koj yuav tsum muab qhov chaw nyob sib txuas lus yooj yim rau txhua GDU ntawm cov zaub ntawm chav tsev, cov cuab yeej pabcuam lossis lub cuab yeej PC.
• Nrog rau qhov chaw nyob yooj yim no, cov ntaub ntawv ntawm Sensor Cartridge muab rau cov tswv yim 1 raug xa los ntawm lub tsheb npav ÿeld mus rau tus tswj roj.
• Ib qho ntxiv sensor txuas / sau npe ntawm GDU tau txais qhov chaw nyob tom ntej.
• Xaiv cov ntawv qhia zaub mov Chaw nyob thiab nkag mus rau qhov chaw nyob ua ntej raws li Txoj Haujlwm Pabcuam Tsheb npav.
• Yog tias qhov kev sib txuas no tsis zoo, koj tuaj yeem nyeem GDU chaw nyob tam sim no hauv cov ntawv qhia zaub mov "Chaw nyob" txawm nyob rau ntawm cov zaub ntawm lub tsev lossis los ntawm kev ntsaws rau hauv cov cuab yeej pabcuam lossis lub cuab yeej PC.
  0 = Chaw nyob ntawm GDU tshiab
• XX = GDU chaw nyob tam sim no (qhov chaw nyob tso cai ntau yam 1 - 96)
