• Rudzi rwetambo rwekurudyi runoshandiswa (JY(St)Y 2x2x0.8LG kana zvirinani).
• Cable topology uye kureba kwetambo.
• Kukwira kwakaringana kureba kwemasensa
• Kubatanidza kwakaringana paGDU yega yega zvinoenderana neÿg 8
• Kugumisa ne 560 ohms pakutanga uye pakuguma kwechikamu chimwe nechimwe.
• Nyatsoteerera kuti polarities yeBUS_A neBUS_B isadzoserwe shure!

Tarisa Short-circuit / Kuvhiringidza / Cable Kureba kweBazi Remumunda (ona ÿg8.1)

• Iyi nzira inofanirwa kuitwa kune imwe neimwe chikamu.
• Tambo yebhazi yeEld inofanira kuiswa pachiteshi chekubatanidza cheGDU pakuyedzwa uku. Iyo plug, zvisinei, haisati yabatanidzwa muGDU.

Bvisa bhazi re sseld rinotungamira kubva kuControl Unit central control. Batanidza ohmmeter kune yakasununguka inotungamira uye kuyera iyo yakazara loop kuramba. Ona ÿg. 8.1 Iyo yakazara loop kuramba inoverengerwa seizvi:

• R (zvese) = R (tambo) + 560 Ohm (kugumisa kuramba)
• R (tambo) = 72 Ohm/km (loop resistance) (tambo yemhando JY(St)Y 2x2x0.8LG)

R (zvese) (ohm)	Chikonzero	Kugadzirisa matambudziko
<560	Short-circuit	Tarisa pfupi pfupi mundima yebhazi tambo.
zvisingaperi	Vhura-wedunhu	Tarisa kukanganiswa mumunda webhazi tambo.
> 560 <640	Cable yakanaka	—

Iyo yakabvumirwa tambo urefu hunogona kuverengerwa nenzira yakakwana chaiyo maererano neinotevera formula.

• Yese kureba kwetambo (km) = (R (zvese) - 560 Ohm) / 72 Ohm
• Kana tambo yebhazi yeEseld yakanaka, batanidza zvakare kune yepakati unit.

Tarisa Voltage uye Bus Polarity yeMunda Bus (ona ÿg 8.2 uye 8.3)

• Iyo bhazi yekubatanidza inofanirwa kubatirwa muGDU yega yega.
• Chinja vhoriyamu yekushandisatage pa Controller Unit central unit.
• Iyo yakasvibirira LED paGDU inovhenekera isina simba kana inoshanda voltage inoshandiswa (voltage chiratidzo).
• Tarisa kushanda voltage uye polarity yebhazi paGDU yega yega maererano ne ÿg. 7.1 uye 7.2. Umin = 16 V DC (20 V DC Yebasa Rinorema)

Bus polarity:
Yera kusawirirana kweBUS_A kupikisa 0 V DC uye BUS_B ichipikisa 0 V DC. U BUS_A = ca. 0.5 V > U BUS_B
U BUS_B = ca. 2 - 4 V DC (zvichienderana nehuwandu hweGDU uye kureba kwetambo)

Kutaura neGDU

• Mushure mekutarisa bhazi reSeld zvakabudirira, unofanirwa kupa kero yekutanga yekutaurirana kune yega GDU kuburikidza nechiratidziro payuniti, chishandiso chesevhisi kana PC chishandiso.
• Iine kero yakakosha iyi, iyo data yeSensor Cartridge yakagoverwa kuisa 1 inotumirwa kuburikidza nebhazi reseld kune gasi controller.
• Chero imwezve sensor yakabatana / yakanyoreswa paGDU inowana otomatiki kero inotevera.
• Sarudza iyo menyu Kero uye isa iyo yakafanotemerwa Kero zvinoenderana neBhazi Kero Chirongwa.
• Kana kubatana uku kwakanaka, unogona kuverenga ikozvino GDU kero mumenyu "Kero" kungave kuri kuratidzwa payuniti kana nekubatanidza sevhisi chishandiso kana PC chishandiso.
  0 = Kero yeGDU itsva
• XX = Yazvino GDU kero (inobvumirwa kero renji 1 - 96)

Tsanangudzo yakadzama yekero inogona kutorwa kubva mubhuku rekushandisa reControl unit kana Controller unit service tool.

FAQs

• Mubvunzo: Ma sensors anofanirwa kuongororwa kakawanda sei?
  A: Sensors dzinofanirwa kuedzwa gore negore kuti dzienderane nemitemo.
• Mubvunzo: Chii chinofanira kuitwa mushure mekudonha kwegasi rakawanda?
  A: Mushure mekubuda kwegasi rakawanda, masensa anofanirwa kuongororwa uye kutsiviwa kana zvichidikanwa. Tevedzera mirau yenzvimbo yekuenzanisa kana yekuongorora zvinodiwa.
