Mitsubishi Elevator Nexay VFGH Elevator Commissioning Manual: Safety & Control Panel Guidelines

1. Essential Safety Precautions

1.1 Simba Chekuchengetedza Zvinodiwa

1. Capacitor Discharge Verification

   • Mushure mekucheka simba guru rekusimudza, iyo DCV LED pane surge absorber board (KCN-100X) ichadzima mukati me ~ 10 seconds.

   • Chiito ChakakoshaUsati washandisa dhiraivha maseketi, shandisa voltmeter kuratidza kuti vhezheni pane main capacitor iri pedyo ne zero.

2. Group Control Panel Hazard

   • Kana chirongwa chekudzora cheboka chaiswa, materminals akagovaniswa (mater-marked terminals/connectors) anoramba ari mupenyu kunyangwe kana rifiti imwe chete yekudzora pani yakadzimwa.

1.2 Control Panel Operational Guidelines

1. ESD Dziviriro yeSemiconductors

   • Dzivisa kusangana zvakananga ne-base-triggered semiconductor components paE1 (KCR-101X) kana F1 (KCR-102X) mabhodhi. Static discharge inogona kukuvadza IGBT modules.

2. IGBT Module Replacement Protocol

   • Kana IGBT module ikatadza, chinjaese modulesmukati meiyo inoenderana rectifier / inverter unit kuti ive nechokwadi chekuvimbika kwehurongwa.

3. Foreign Object Prevention

   • Rambidza kuisa zvikamu zvesimbi zvisina kusimba (semuenzaniso, screws) pamusoro pepaneru yekudzora kudzivirira njodzi yenguva pfupi.

4. Power-On Restrictions

   • Usambofa wakapa simba dhiraivha unit kana chero chinongedzo chisina kuburitswa panguva yekutumwa kana kugadzirisa.

5. Workspace Optimization

   • Mumakamuri emuchina akavharirwa, mativi akachengeteka/kumashure control panel anovhara pamberi pekuiswa kwekupedzisira. Sevhisi yese inofanira kuitika kubva kumberi.

6. Parameter Kuchinja Maitiro

   • Seta iyoR/M-MNT-FWR shandura chinjakuMNT chinzvimbousati wachinja maparamita echirongwa cheelevator.

2. Power Supply Verification

2.1 Kudzora Voltage Kuongorora

Simbisa mari yekupinda/inobuditsa pane dzakatarwa kuyerwa nzvimbo:

P1 Board Power Supply Verification:

• -12V kusvika GND: DC-12V (±5%)

• +12V kuenda kuGND: DC+12V (±5%)

• +5V kuenda kuGND: DC+5V (±5%)

2.2 Mota & Yekumisikidza Simba rekupa Chengetedza

Gadzirisa AC voltage yekabhini uye yekumhara masisitimu:

2.3 Chibatanidza & Circuit Breaker Kuongorora

1. Pre-Energization Matanho:

   • DzimaNF-CP,NF-SP,uyeSCBswitches.

   • Ita shuwa kuti zvese zvinongedzo zvakabatidzwaP1uyeR1 mapurangadzakavharirwa mukati zvakachengeteka.

2. Sequential Power-On Protocol:

   • Mushure mekuita NF-CP/NF-SP/SCB, simba PANE mabhamuki ekuchengetedza uye ma switch ekudzivirira edunhuimwe panguva.

   • Pamaseketi emagetsi akasarudzika, simbisa kutevedza kwemagetsipamberikuvhara switch:

   Power Circuit	Protection Switch	Measurement Point	Standard Voltage	Kushivirira
   DC48V	ZCA	Chikamu chekutanga ↔ Terminal 107	DC48V	±3V
   DC24V	ZCB	Chikamu chekutanga ↔ Terminal 107	DC24V	±2V

3. Backup Power Yambiro:

   • USAbate chikamu chechipiri cheBTP yedunhu mudziviriri-Simba rekuchengetedza rinoramba richishanda.

3. Mota Encoder Inspection

3.1 Encoder Yekuedza Maitiro

1. Simba Kuzviparadzanisa nevamwe:

   • Dzima iyoNF-CP simba switch.

2. Encoder Disconnection:

   • Bvisa encoder yekubatanidza padivi remuchina wekudhonza.

   • Sunungura masiruuru anokwirisa encoder.

3. PD4 Connector Verification:

   • Simbisa yakachengeteka kubatana kwePD4 plugpaP1 board.

4. Voltage Check:

   • Batidza NF-CP.

   • Pima voltage pane encoder yekubatanidza:

     • Pini 1 (+) ↔ 2 (–):+12V ±0.6V(critical tolerance).

5. Reconnection Protocol:

   • BIMA NF-CP.

   • Batanidza zvakare encoder yekubatanidza.

6. Parameter Configuration:

   • Batidza NF-CP.

   • Seta P1 bhodhi rotary potentiometers:

     • MON1 = 8,MON0 = 3.

7. Direction Simulation Test:

   • Tenderedza encoder kutevedzera elevatorUPdirection.

   • Confirm7SEG2 inoratidza "iwe"(ona Mufananidzo 4).

   • Kana "d" ichionekwa: Chinjana encoder wiring pairs:

     • ENAP ↔ ENBPuyeENAN ↔ ENBN.

8. Kupedzisa:

   • Nyatsoomesa encoder mounting screws.

4 LED Status Diagnostics

Tarisa kuMufananidzo 1 wezvirongwa zvebhodhi.

Macheki Akakosha:

1. Rectifier Unit Validation:

   • Mushure mekuwedzera simba,CFO pa7SEG inofanira kuvhenekera.

   • Kana CFO yadzimwa: Ongorora simba redunhu wiring uye kutevedzana kwechikamu.

2. WDT Status Verification:

   • Simbisa kuvhenekera kwe:

     • CWDTuyeMWDT(KCD-100X)

     • WDT(KCD-105X)

   • Kana WDT yakadzimwa:

     • Check+ 5V kupauye chokubatanidza kuvimbika.

3. Capacitor Charge Circuit Test:

   • LED DCVpane capacitor board (KCN-1000/KCN-1010) inofanira:

     • Ratidza kana wabatidzwa.

     • Kudzima~10 secondsmushure memagetsi-kudzima.

   • Abnormal CVD maitiro: Kuongorora:

     • Inverter unit

     • Charge/discharge circuits

     • Capacitor terminal voltage
