Kev nyab xeeb Circuit Court (SF)

4.1 Txheej txheem cej luam

CovKev nyab xeeb Circuit Court (SF)ua kom txhua yam khoom siv hluav taws xob thiab hluav taws xob muaj kev nyab xeeb ua haujlwm. Nws tiv thaiv kev ua haujlwm of elevator yog tias muaj kev nyab xeeb ua txhaum cai (xws li, qhib qhov rooj, overspeed).

Cov ntsiab lus tseem ceeb

1. Kev Nyab Xeeb Kev Nyab Xeeb (#29):

   • Series-txuas kev nyab xeeb hloov pauv (xws li, qhov hloov pauv, tus tswv xeev, nres thaum muaj xwm ceev).

   • Powers kev ruaj ntseg relay#89(los yog cov logic sab hauv hauv C-lus P1 boards).

2. Qhov rooj xauv Circuit Court (#41DG):

   • Series-txuas qhov rooj xauv (lub tsheb + tsaws qhov rooj).

   • Tsim los ntawm#78(tso tawm los ntawm kev ruaj ntseg chain).

3. Qhov Rooj Saib Xyuas Kev Nyab Xeeb:

   • Parallel rau qhov rooj xauv. Ua kom tsuas yog thaum lub qhov rooj qhib hauv thaj chaw tsaws.

Muaj nuj nqi tseem ceeb:

• Txiav lub zog rau#5 (lub ntsiab contactor)thiab#LB (brake contactor)yog ua rau.

• Saib xyuas ntawm LEDs ntawm P1 board (#29, #41DG, #89).

4.2 Cov kauj ruam daws teeb meem dav dav

4.2.1 Fault Identification

Cov tsos mob:

• #29 / #89 LED tawm→ Kev ruaj ntseg saw cuam tshuam.

• Thaum muaj xwm ceev nres→ Kev nyab xeeb Circuit Court tshwm sim thaum ua haujlwm.

• Tsis muaj pib→ Kev nyab xeeb Circuit Court qhib thaum so.

Diagnostic Methods:

1. LED Qhov taw qhia:

   • Kos P1 board LEDs (#29, #41DG) rau qhib circuits.

2. Fault Codes:

   • Piv txwv li, "E10" rau kev ruaj ntseg saw cuam tshuam (rau kev ua txhaum ib ntus).

4.2.2 Fault Localization

1. Stable Qhib Circuit:

   • Sivzone-raws li kev xeem: Ntsuas qhov hluav taws xob ntawm cov ntsiab lus sib txuas (piv txwv li, lub qhov, chav tshuab).

   • Piv txwv: Yog tias qhov hluav taws xob poob ntawm qhov sib txuas J10-J11, tshawb xyuas cov keyboards hauv cheeb tsam ntawd.

2. Intermittent Qhib Circuit:

   • Hloov cov keyboards uas txawv txav (piv txwv li, hnav lub qhov hloov).

   • Bypass xeem: Siv cov xov hlau seem kom rov txuas ntxiv txuas cov kab txuas (cais cov keyboards).

CEEB TOOM: Tsis txhob luv-circuit kev nyab xeeb hloov rau kev sim.

4.2.3 Qhov Rooj Cheeb Tsam Kev Nyab Xeeb Tsis Zoo

Cov tsos mob:

• Sudden nres thaum lub sij hawm re-leveling.

• Cov lej yuam kev ntsig txog qhov chaw teeb liab (RLU/RLD).

Keeb kwm:

1. Misaligned Door Zone Sensors (PAD):

   • Kho qhov sib txawv ntawm PAD thiab magnetic vane (feem ntau 5-10mm).

2. Faulty Relays:

   • Test relays (DZ1, DZ2, RZDO) ntawm kev tiv thaiv boards.

3. Teeb liab teeb meem:

   • Tshawb xyuas cov kab hluav taws xob tawg / tiv thaiv nyob ze ntawm cov motors lossis high-voltage cables.

4.3 Kev Ua Phem & Kev daws teeb meem

4.3.1 #29 LED Tawm (Kev Nyab Xeeb Qhib)

4.3.2 #41DG LED Tawm (Qhov Rooj Xauv Qhib)

4.3.3 Nres Thaum Muaj Xwm Ceev + khawm teeb rau

4.3.4 Nres Thaum Muaj Xwm Ceev + Khawm Teeb Tawm
