1.1 Leveling Switches (PAD Sensors)

Muaj nuj nqi: Tshawb xyuas lub tsheb txoj hauj lwm rau pem teb theem, qhov chaw ua haujlwm ntawm lub qhov rooj, thiab qhov chaw rov ua haujlwm.
Common Signal Combinations:
- TZD/DZU: Lub qhov rooj loj nrhiav kom pom (lub tsheb hauv ± 50mm ntawm pem teb theem).
- RLD/UA: Re-leveling tsam (nqaim dua DZD/DZU).
- FDZ/RDZ: Pem hauv ntej / nram qab qhov rooj teeb liab (rau ob lub qhov rooj).
Txoj Cai Tseem Ceeb:
- - Yog tias RLD / RLU ua haujlwm, DZD / DZUyuav tsumkuj yuav nquag. Kev ua txhaum cai ua rau lub qhov rooj tiv thaiv kev nyab xeeb (saibSF Circuit).

1.2 Terminal Hloov

Hom	Muaj nuj nqi	Qib kev nyab xeeb
Deceleration	txwv lub tsheb ceev ze ntawm cov davhlau ya nyob twg; pab kho txoj hauj lwm.	Tswj teeb liab (mos nres).
Txwv	Tiv thaiv kev hla dhau ntawm cov davhlau ya nyob twg (xws li USL/DSL).	Kev nyab xeeb Circuit Court (nres nres).
Qhov kawg txwv	Last-resort mechanical stop (eg, UFL/DFL).	Txiav #5/#LB zog.

Nco tseg: Tshuab-chav-tsawg (MRL) elevators yuav rov ua dua lub davhlau ya nyob twg sab saud raws li kev txwv kev ua haujlwm.

2 Cov kauj ruam daws teeb meem dav dav

2.1 Leveling Hloov Faults

Cov tsos mob:

Kev ua haujlwm tsis zoo (± 15mm yuam kev).
Nquag re-leveling lossis "AST" (Abnormal Stop) ua txhaum.
Kev sau npe hauv pem teb tsis raug.

Diagnostic cov kauj ruam:

PAD Sensor Check:
- Txheeb xyuas qhov sib txawv ntawm PAD thiab magnetic vane (5-10mm).
- Test sensor tso zis nrog multimeter (DC 12-24V).
Teeb liab validation:
- Siv P1 lub rooj tsavxwmdebug homlos tso saib PAD teeb liab ua ke thaum lub tsheb hla hauv pem teb.
- Piv txwv li: Code "1D" = DZD nquag; "2D" = DZU active. Kev tsis sib haum xeeb qhia cov sensors tsis raug.
Kev tshuaj xyuas kab mob:
- Tshawb xyuas cov kab hluav taws xob tawg / tiv thaiv ze ntawm cov motors lossis cov kab hluav taws xob siab.

2.2 Terminal Hloov Faults

Cov tsos mob:

Thaum muaj xwm ceev nres nyob ze ntawm cov terminals.
Tsis yog lub davhlau ya nyob twg deceleration.
Tsis muaj peev xwm sau npe hauv pem teb dav hlau ("sau txheej" tsis ua haujlwm).

Diagnostic cov kauj ruam:

Tiv tauj-Hom Switches:
- Khoactuator dogntev los xyuas kom meej ib txhij triggering ntawm nyob ib sab keyboards.
Non-Contact (TSD-PAD) Hloov:
- Validate hlau nplaum phaj sib lawv liag thiab sij hawm (siv oscilloscope rau teeb liab tsom xam).
Teeb liab Tracing:
- Ntsuas qhov hluav taws xob ntawm W1 / R1 board terminals (piv txwv li, USL = 24V thaum triggered).

3 Kev Ua Phem & Kev daws teeb meem

3.1 Tsis muaj peev xwm sau npe hauv pem teb qhov siab

Ua rau	Kev daws
Faulty Terminal Hloov	- Rau TSD-PAD: Txheeb xyuas cov hlau nplaum phaj qhov tob (≥20mm). - Rau kev sib txuas lus: Kho USR / DSR actuator txoj haujlwm.
PAD teeb liab yuam kev	Paub meej tias DZD / DZU / RLD / RLU teeb liab ncav cuag lub rooj tswj hwm; xyuas PAD alignment.
Board Fault	Hloov P1 / R1 board lossis hloov kho software.

3.2 Tsis Siv Neeg Terminal Re-Leveling

Ua rau	Kev daws
TSD Misalignment	Rov ntsuas TSD kev teeb tsa ib daim duab kos (qhov kam rau ua: ± 3mm).
Txoj hlua Slippage	Tshawb xyuas traction sheave groove hnav; Hloov cov hlua yog slippage> 5%.

3.3 Nres Thaum Muaj Xwm Ceev ntawm Terminals

Ua rau	Kev daws
Incorrect TSD Sequence	Validate hlau nplaum phaj coding (piv txwv li, U1 → U2 → U3).
Actuator Dog Fault	Kho qhov ntev kom ntseeg tau tias sib tshooj nrog kev txwv hloov pauv.
