Mitsubishi Elevator Safety Circuit (SF) Troubleshooting Guide
Sadunhu Denderedzwa (SF)
4.1 Muchidimbu
TheSadunhu Denderedzwa (SF)inova nechokwadi chekuti zvese zvekuchengetedza zvemagetsi nemagetsi zviri kushanda. Inodzivirira kushanda kweelevator kana chero mamiriro ekuchengetedza akatyorwa (semuenzaniso, magonhi akazaruka, overspeed).
Zvikamu Zvikuru
-
Cheni yekuchengetedza (#29):
-
Series-yakabatana kuchengetedza switch (semuenzaniso, gomba switch, gavhuna, emergency stop).
-
Masimba kuchengetedza relay#89(kana pfungwa yemukati muC-mutauro P1 mabhodhi).
-
-
Door Lock Circuit (#41DG):
-
Series-yakabatana makiyi egonhi (mota + yekumhara magonhi).
-
Powered by#78(zvinobuda kubva kune cheni yekuchengetedza).
-
-
Door Zone Safety Check:
-
Parallel to door locks. Inoshanda chete kana magonhi akavhurika munzvimbo yekumhara.
-
Akakosha Mabasa:
-
Inocheka simba kuti#5 (main contactor)uye#LB (brake contactor)kana yakakonzerwa.
-
Inotariswa kuburikidza ne LEDs paP1 board (#29, #41DG, #89).
4.2 General Troubleshooting Matanho
4.2.1 Kuziva Mhosva
Zviratidzo:
-
#29/#89 LED yadzimwa→ Cheni yekuchengetedza yakakanganiswa.
-
Emergency stop→ Chengetedzo yedunhu yakakonzeresa panguva yekushanda.
-
Hapana kutanga→ Saiti yekuchengetedza yakavhurika pakuzorora.
Diagnostic Nzira:
-
LED Indicators:
-
Tarisa P1 bhodhi LEDs (#29, #41DG) kune akavhurika maseketi.
-
-
Fault Codes:
-
Eg, "E10" yekukanganisa cheni yekuchengetedza (yekukanganisa kwenguva pfupi).
-
4.2.2 Kukanganisa Nzvimbo
-
Yakagadzikana Yakavhurika Circuit:
-
Shandisazone-based test: Kuyera voltage panzvimbo dzekusangana (semuenzaniso, gomba, imba yemuchina).
-
Muenzaniso: Kana magetsi akadonha pakati pejunction J10-J11, tarisa switch munzvimbo iyoyo.
-
-
Intermittent Open Circuit:
-
Tsiva ma switch anofungidzirwa (semuenzaniso, chinja chegomba chakasakara).
-
Bypass bvunzo: Shandisa waya dzakasara kuti ubatanidze tambo zvikamu (bvisa maswichi)
-
YAMBIRO: Usambofa wakapfupika-sekete kuchengetedza switch yekuyedza.
4.2.3 Door Zone Safety Mhosho
Zviratidzo:
-
Kamwe kamwe inomira panguva yekudzokorora zvakare.
-
Mhosva makodhi ane hukama nemasaini enzvimbo yemusuwo (RLU/RLD).
Zvikonzero:
-
Misaligned Door Zone Sensors (PAD):
-
Gadzirisa gap pakati pePAD uye magineti vane (kazhinji 5-10mm).
-
-
Dzakakanganiswa Relays:
-
Test relays (DZ1, DZ2, RZDO) pamabhodhi ekudzivirira.
-
-
Signal Wiring Issues:
-
Tarisa uone kana waya dzakatyoka/dzivirirwa pedyo nemamota kana tambo dzemagetsi.
-
4.3 Zvakajairwa Mhosho & Mhinduro
4.3.1 #29 LED Off (Safety Chain Vhura)
| Chikonzero | Solution |
|---|---|
| Vhura Chengetedza Chinja | Yedza machinja akatevedzana (semuenzaniso, gavhuna, gomba switch, kumira kwechimbichimbi). |
| 00S2/00S4 Chiratidzo Kurasika | Chengetedza zvinongedzo ku400chiratidzo (yemhando chaiyo). |
| Kukanganisa Kuchengetedza Board | Tsiva W1/R1/P1 bhodhi kana kumhara yekuongorora panel PCB. |
4.3.2 #41DG LED Off (Door Kiya Vhura)
| Chikonzero | Solution |
|---|---|
| Faulty Door Lock | Ongorora mota / yekumhara makiyi emasuo ane multimeter (kuenderera bvunzo). |
| Banga reDoor risina kurongeka | Gadzirisa gonhi banga-ku-roller gap (2-5mm). |
4.3.3 Emergency Stop + Bhatani Mwenje Yakabatidzwa
| Chikonzero | Solution |
|---|---|
| Kuvhiringwa kweKiyi yedhoo | Tarisa kuvharika kwekiyi yemusuwo panguva yekumhanya (semuenzaniso, kupfeka kwemaroza). |
4.3.4 Emergency Stop + Bhatani Mwenje Adzima
| Chikonzero | Solution |
|---|---|
| Safety Chain Yakamutswa | Ongorora maswiti egomba kuti ane ngura/tambo inokonzeresa; test overspeed gavhuna. |

Zvinyorwa Zvinyorwa:
Gwaro iri rinoenderana neMitsubishi elevator zviyero. Gara uchidzima simba usati waedza uye bvunza modhi-chaiwo zvinyorwa.
