Mitsubishi Elevator Safety Circuit (SF) Kuwongolera Mavuto

Dera lachitetezo (SF)

4.1 Mwachidule

TheDera lachitetezo (SF)imawonetsetsa kuti zida zonse zamakina ndi zamagetsi zamagetsi zikugwira ntchito. Zimalepheretsa kukwera kwa elevator ngati vuto lililonse lachitetezo likuphwanyidwa (mwachitsanzo, zitseko zotseguka, kuthamanga kwambiri).

Zigawo Zofunikira

1. Unyolo Wachitetezo (#29):

   • Zosintha zachitetezo zolumikizidwa ndi mndandanda (mwachitsanzo, kusintha kwa dzenje, kazembe, kuyimitsa mwadzidzidzi).

   • Mphamvu zopatsirana zotetezedwa#89(kapena malingaliro amkati mu C-language P1 board).

2. Dongosolo Lotseka Pakhomo (#41DG):

   • Maloko olumikizidwa ndi Series (galimoto + zitseko zolowera).

   • Mothandizidwa ndi#78(zotuluka kuchokera kuchitetezo chachitetezo).

3. Door Zone Safety Check:

   • Kufanana ndi maloko a zitseko. Imayatsa pokhapokha zitseko zili zotseguka mu malo otsetsereka.

Ntchito Zovuta:

• Amadula mphamvu kuti#5 (wothandizira wamkulu)ndi#LB (brake contactor)ngati yayambitsidwa.

• Kuyang'aniridwa ndi ma LED pa bolodi la P1 (#29, #41DG, #89).

4.2 Njira Zothetsera Mavuto Onse

4.2.1 Kuzindikira Zolakwa

Zizindikiro:

• #29/#89 LED yozimitsa→ Unyolo wachitetezo wasokonezedwa.

• Kuyimitsa mwadzidzidzi→ Dera lachitetezo lidayambika panthawi yogwira ntchito.

• Palibe zoyambira→ Dera lachitetezo limatsegulidwa pakupuma.

Njira Zodziwira:

1. Zizindikiro za LED:

   • Onani ma P1 board LEDs (#29, #41DG) pamabwalo otseguka.

2. Makodi Olakwika:

   • Mwachitsanzo, "E10" ya kusokonezedwa kwa unyolo wachitetezo (pazovuta zosakhalitsa).

4.2.2 Kukhazikitsa Zolakwa

1. Stable Open Circuit:

   • Gwiritsani ntchitokuyezetsa kotengera zone: kuyeza voteji pa mphambano (monga dzenje, makina chipinda).

   • Chitsanzo: Ngati magetsi atsika pakati pa mphambano ya J10-J11, yang'anani masiwichi omwe ali m'derali.

2. Intermittent Open Circuit:

   • Sinthani masiwichi okayikitsa (mwachitsanzo, masiwichi owonongeka).

   • Mayeso a bypass: Gwiritsani ntchito mawaya opuma kuti mulumikizenso magawo a chingwe (osaphatikiza zosintha).

CHENJEZO: Osasintha masiwichi otetezeka afupipafupi poyesa.

4.2.3 Zowonongeka Zachitetezo Pazitseko

Zizindikiro:

• Kuyima kwadzidzidzi panthawi yokonzanso masinthidwe.

• Manambala olakwika okhudzana ndi ma sign zone (RLU/RLD).

Zomwe Zimayambitsa:

1. Zomverera za Door Zone Zolakwika (PAD):

   • Sinthani kusiyana pakati pa PAD ndi maginito vane (nthawi zambiri 5-10mm).

2. Ma Relay Olakwika:

   • Kutumiza koyesa (DZ1, DZ2, RZDO) pama board achitetezo.

3. Mavuto a Wiring Signal:

   • Yang'anani mawaya osweka/otetezedwa pafupi ndi ma motors kapena zingwe zamphamvu kwambiri.

4.3 Zolakwika Zofala & Mayankho

4.3.1 #29 LED Off (Safety Chain Open)

4.3.2 #41DG LED Off (Door Lock Open)

4.3.3 Kuyimitsa Kwadzidzidzi + Mabatani Oyatsa

4.3.4 Kuyimitsa Kwadzidzidzi + Mabatani Oyatsa

Zolemba Zolemba:
Bukuli likugwirizana ndi miyezo ya Mitsubishi elevator. Nthawi zonse zimitsani mphamvu musanayese ndikufunsanso zolemba zachitsanzo.
