• Sensa imatenthedwa ndi gasi (chifukwa cha izi, mufunika botolo la gasi lokhala ndi chowongolera komanso chowongolera).
• Pochita izi, ma alarm omwe amayikidwa amadutsa, ndipo ntchito zonse zotuluka zimatsegulidwa. Ndikofunikira kuyang'ana ngati zotuluka zolumikizidwa zikugwira ntchito moyenera (kulira kwa lipenga, mafani amayatsa, ndi zida kuzimitsa). Mwa kukanikiza batani la kukankhira pa nyanga, kuvomereza kwa nyanga kuyenera kufufuzidwa
• . Pambuyo pa kuchotsedwa kwa gasi wofotokozera, zotuluka zonse ziyenera kubwereranso kumalo awo oyambirira.
• Kupatula kuyesa kosavuta kwa magwiridwe antchito, ndizothekanso kuyesa magwiridwe antchito pogwiritsa ntchito calibration. Kuti mudziwe zambiri, chonde onani Buku Logwiritsa Ntchito.

Controller Unit angapo GDU commissioning

Kuti mutumize mwachangu komanso momasuka timalimbikitsa kuchita motere. Makamaka zomwe zaperekedwa za chingwe cha basi ya seld ziyenera kuyang'aniridwa mosamala, chifukwa ndipamene zambiri zomwe zimayambitsa mavuto mu bus ya seld zimawonekera.

Kuwunika kwa Optical

• Chingwe choyenera chimagwiritsidwa ntchito (JY(St)Y 2x2x0.8LG kapena kuposa).
• Topology ya chingwe ndi kutalika kwa chingwe.
• Kukwera koyenera kwa masensa
• Kulumikizana kolondola pa GDU iliyonse malinga ndi ÿg 8
• Kuthetsa ndi 560 ohms kumayambiriro ndi kumapeto kwa gawo lililonse.
• Samalani kwambiri kuti ma polarities a BUS_A ndi BUS_B asasinthidwe!

Yang'anani Kutalika Kwafupika / Kusokoneza / Kutalika kwa Chingwe kwa Field Bus (onani ÿg8.1)

• Njira iyi iyenera kuchitidwa pagawo lililonse.
• Chingwe chabasi cha ÿeld chiyenera kuyikidwa pa cholumikizira cholumikizira cha GDU poyesa izi. Pulagi, komabe, sinalowe mu GDU.

Chotsani mabasi a sseld kuchokera ku Controller Unit central control. Lumikizani ohmmeter kumalo otayirira ndikuyesa kukana kwathunthu kwa loop. Onani ÿg. 8.1 Kukana konse kwa loop kumawerengedwa motere:

• R (chiwerengero) = R (chingwe) + 560 Ohm (kuthetsa kukana)
• R (chingwe) = 72 Ohm/km (kukana kwa loop) (mtundu wa chingwe JY(St)Y 2x2x0.8LG)

R (chinthu chonse) (ohm)	Chifukwa	Kusaka zolakwika
<560	Short-circuit	Yang'anani dera lalifupi mu chingwe cha basi.
wopandamalire	Tsegulani kuzungulira	Yang'anani kusokoneza mu chingwe cha basi.
560 <640	Chingwe chili bwino	—

Kutalika kwa chingwe chololedwa kungathe kuwerengedwa mokwanira ndendende molingana ndi ndondomekoyi.

• Kutalika konse kwa chingwe (km) = (R (chiwopsezo) - 560 Ohm) / 72 Ohm
• Ngati chingwe cha basi ya seld chili bwino, chilumikizeninso pagawo lapakati.

Fufuzani Voltage ndi Bus Polarity of the Field Bus (onani ÿg 8.2 ndi 8.3)

• Cholumikizira basi chiyenera kulumikizidwa mu GDU iliyonse.
• Kusintha voltage pa Controller Unit central unit.
• LED yobiriwira ku GDU imawunikira mofooka pamene volyumu yogwira ntchitotage amagwiritsidwa ntchito (voltagndi chizindikiro).
• Onani kuchuluka kwa ntchitotage ndi polarity ya basi pa GDU iliyonse malinga ndi ÿg. 7.1 ndi 7.2. Umin = 16 V DC (20 V DC pa Ntchito Yolemera)

Polarity ya basi:
Yezerani kuthamanga kwa BUS_A motsutsana ndi 0 V DC ndi BUS_B motsutsana ndi 0 V DC. U BUS_A = ca. 0.5 V > U BUS_B
U BUS_B = ca. 2 - 4 V DC (kutengera kuchuluka kwa GDU ndi kutalika kwa chingwe)

Kulankhula ndi GDU

• Mukayang'ana basi ya seld bwino, muyenera kugawa adilesi yoyankhulirana kwa GDU iliyonse kudzera pachiwonetsero pagawo, chida chautumiki kapena chida cha PC.
• Ndi adilesi yoyambira iyi, data ya Sensor Cartridge yoperekedwa kulowetsa 1 imatumizidwa kudzera pa basi ya seld kupita kwa wowongolera gasi.
• Sensor ina iliyonse yolumikizidwa / yolembetsedwa pa GDU imangopeza adilesi yotsatira.
• Sankhani menyu Adilesi ndikulowetsani Adilesi yokonzedweratu malinga ndi Bus Address Plan.
• Ngati kulumikizanaku kuli bwino, mutha kuwerenga adilesi yaposachedwa ya GDU pamenyu "Adilesi" mwina pawonetsero pagawo kapena polumikiza chida chautumiki kapena chida cha PC.
  0 = Adilesi ya GDU yatsopano
• XX = Adilesi Yapano ya GDU (maadiresi ovomerezeka 1 - 96)

Kufotokozera mwatsatanetsatane kwa maadiresi kungatengedwe kuchokera ku bukhu la ogwiritsa ntchito la Controller unit kapena Controller unit service tool.
