1 Va'aiga lautele o Faiga Feso'ota'iga Elevator

Lisi feso'ota'iga eletise (OR) fa'amautinoa le fa'alagolagoina o fa'amatalaga fa'amatalaga i le va o vaega taua, e a'afia sa'o ai le saogalemu ma le lelei. O lenei taiala e aofia aiMAFAI pasimaRS-faasologa fa'asologa, tuʻuina atu faʻamatalaga faʻapitoa mo le tausiga ma SEO-optimized troubleshooting strategy.

1.1 CAN Bus System

Vaega Autu

• Topology: Feso'ota'iga pasi e tele-node e lagolagoina feso'ota'iga atoa-duplex.

• Tulaga Fa'aeletise:

  • Fa'ailoga Eseese: CAN_H (Maualuga) ma CAN_L (Low) uaea mimilo-paiga mo le leo leo.

  • Tulaga Malosi: Pulea (CAN_H=3.5V, CAN_L=1.5V) vs. Recessive (CAN_H=2.5V, CAN_L=2.5V).

• Fa'amuamua Mechanism:

  • Fa'ailoga ID maualalo = Fa'amuamua maualuga (fa'ata'ita'iga, ID 0 > ID 100).

  • Fo'ia o fete'ena'iga e ala i le aveese otometi le node.

Talosaga

• Mata'ituina le saogalemu i taimi moni

• Fa'amaopoopo pulega fa'avae

• Fa'asalalau fa'ailoga sese

Fa'amatalaga Uea

1.2 RS-Series Feso'ota'iga Protocols

Fa'atusatusaga fa'akomepiuta

Fa'aoga autu

• RS-485: Hall valaau faiga, manatu faaalia tulaga taavale.

• RS-232: Tausiga feso'ota'iga komepiuta.

Fa'atonu Taiala

• Fa'aogauaea talipupuni mimilo(AWG22 pe mafiafia).

• Fa'ai'u pasi i le120Ω tetee.

• Aloese mai topologi fetu; faamuamuasootaga daisy-chain.

1.3 Fa'ata'ita'iga Feso'ota'iga Elevator

Fa Subsystems autu

1. Pulea Vaega: Fa'amaopoopo le tele o lifi e ala i pasi CAN.

2. Faiga o Ta'avale: Puleaina tulafono i totonu e ala i le RS-485.

3. Maota o Hall: Taulima valaau mai fafo; manaomiapusa eletise hall(H10-H20).

4. Galuega Ausilali: Avanoa tagata fuimu, mataʻituina mamao.

Pulea Malosiaga

1.4 Fa'afitauli Taiala

1. Siaki Autu:

   • Fua le eletise pasi (CAN: 2.5-3.5V; RS-485: ± 1.5-5V).

   • Fa'amaonia fa'agata fa'agata (120Ω mo CAN/RS-485).

2. Iloiloga Faailoga:

   • Fa'aaoga le oscilloscope e iloa ai le fa'aletonu o galu.

   • Mataʻituina le uta o le pasi (

3. Su'ega Tuto'atasi:

   • Mo'esea nodes e iloa ai vaega sese.

   • Suia vaega masalomia (fa'ata'ita'iga, pusa eletise faletele).

Ata 1: Ata o Faiga Feso'ota'iga Eleva

2 Laasaga lautele e foia ai faafitauli

O fa'aletonu tau feso'ota'iga i faiga fa'aelefi e mafai ona fa'aalia i ni auala 'ese'ese, ae o le mulimulita'i i se faiga fa'atulagaina e mautinoa ai le lelei o su'esu'ega ma fofo. O loʻo i lalo laʻasaga sili ona lelei mo le faʻailoaina ma le foʻia OR mataupu faʻasalalau, faʻatulagaina mo le SEO ma le manino faʻapitoa.

2.1 Su'esu'e Pasi Feso'ota'iga Sese e ala ile P1 Board Error Codes

Gaioiga Autu:

1. Siaki P1 Board Codes:

   • Faiga tuai: Fa'ailoga lautele (fa'ata'ita'iga, "E30" mo fa'alavelave tau feso'ota'iga).

   • Faiga fa'aonaponei: Fa'ailoga auiliili (fa'ata'ita'iga, "CAN Bus Taimi" po'o le "RS-485 CRC Error").

2. Fa'amuamua le Fa'aesea o Fa'ailoga:

   • Fa'ata'ita'iga: O le "Group Control Link Failure" o lo'o fa'ailoa mai ai fa'afitauli pasi CAN, a'o le "Hall Call Time out" fa'asino ile RS-485 fa'aletonu.

2.2 Su'esu'e Laina Malosi & Fa'amatalaga

Su'ega Mata'utia:

1. Fa'aauau Su'ega:

   • Fa'aaoga se multimeter e fa'amaonia ai le sa'o o le uaea. Mo uaea uumi, fai se matasele ma uaea avanoa mo le fua sa'o.

2. Insulation Resistance:

   • Fua i le megohmmeter (>10MΩ mo RS-485;>5MΩ mo CAN pasi).

   • Motugaafa: O fa'ailoga maualuga e fa'ata'ita'i i ta'avale pu'upu'u pe a fa'aleagaina le fa'alava.

3. Fa'amatalaga Fa'asagaga Pa'a:

   • Fa'amaonia le mimilo pitch (tulaga masani: 15–20mm mo CAN; 10–15mm mo RS-485).

   • Aloese mai uaea e le masani—e oo lava i vaega pupuu e fa'alavelaveina le fa'amaoni o fa'ailo.

2.3 Su'esu'e Fa'afitauli Node e ala ile Tulaga LED

Taualumaga:

1. Su'e Nodes Fa'aletonu:

   • CAN nodes: Siaki le "ACT" (activity) ma le "ERR" LEDs.

   • RS-485 nodes: Fa'amaonia fua faatatau emo "TX/RX" (1Hz = masani).

2. Fa'asologa masani o le LED:

   Setete LED	Fa'aliliuga
   GALUEGA tumau, ERR pe	Node galue
   ERR e emo	CRC sese po'o ID fete'ena'i
   ACT/RX tape	Malosi po'o fa'ailo leiloa

2.4 Fa'amaonia Fa'atonu Node & Fa'amuta Fa'agata

Siaki Fa'atonu:

1. Node ID Fa'amaonia:

   • Ia mautinoa e fetaui ID ma tofitofiga fola (fa'ata'ita'iga, Node 1 = fogafale muamua).

   • ID le fetaui e mafua ai le te'ena o pepa po'o feto'ai pasi.

2. Fa'amutaina Resistors:

   • Manaomia ile pito pito ole pasi (120Ω mo CAN/RS-485).

   • Faataitaiga: Afai e sui le node pito mamao, toe sii le tetee.

Mataupu masani:

• Ua misi le fa'amutaina → Fa'ailoga fa'ailoga → Fa'amatalaga pi'opi'o.

• Le sa'o le tau o le tetee → Voltage drop → Fesootaiga le manuia.

2.5 Manatu Faaopoopo

1. Fa'amaumau Firmware:

   • O nodes uma (aemaise lava nofoaga o faletele) e tatau ona fa'aoga tutusa fa'asologa o polokalama faakomepiuta.

2. Meafaigaluega Fegalegaleai:

   • Sui laupapa fa'aletonu i fa'atusa fa'atusa (fa'ata'ita'iga, laupapa R1.2 mo pona R1.2).

3. Malosiaga Faalavelave:

   • Su'e puna'oa AC (fa'ata'ita'iga, moli moli) mo EMI e fa'aaoga ai se su'esu'e alaleo.

   • Fa'apipi'i 'au ferrite i luga o uaea feso'ota'iga lata ane i masini malosi.

3 Fa'aletonu Fesootaiga masani

3.1 Fa'aletonu: Fa'amau Fa'ato'a Ta'avale Le tali

Mafua'aga ma Fofo:

Mafua'aga ma Fofo:

Fautuaga Fa'apitoa mo le Tausiga

1. Su'ega Uaea:

   • Fa'aoga ataimi-itu'aiga reflectometer (TDR)e su'e fa'aletonu uaea i laina laina uumi.

2. Siaki Fa'alelalo:

   • Fua le eletise i le va o talipupuni uaea fesoʻotaʻiga ma le eleele (

3. Fa'afouga Firmware:

   • Faafetaui i taimi uma lomiga firmware laupapa (faataitaiga, P1 v3.2 ma le pule faitotoa v3.2).
