【 Weak current College 】 OTIS Otis Elevator malfunction set II

Fault 51: 3100 elevator car stopped on the 3 floor anomalies-10 centimeters, showing a bumper unable to run the repair operation is out, after the examination found C1 contactor 21.22 contactor.

Fault 52: otis3100 symptom DZ not lit LVC not snap-action, according to LVC coil without 24V,. investigation no output DC24V LCB2, replace LCB2DC24 voltage manifold LM7824 the manifold after normal is Motorola's power over other model 1A. This failure by cnngaigh provides.

Fault 53: gen2 open climbing not panic drive fast die twice and then beat overhaul did not move, be sure to pull to, later on, the original TT two brake switch bs1bs2 are not synchronized.

Fault 54: [br] 300vf elevator, the runtime always appear sudden stop, and then addressing leveling, and continue to run, in response to previous outbound or internal elections. M4211, i.e. the current display: elevator malfunction, the inverter InverterOCT overcurrent. And monitor directory record for F101, inverter over current, over current protection in DSP implementation, when the fault is detected will stop base. This protection by comparing the current intensity and predefined error point (an E ^ 2 parameter represents the highest line currents). Find information on the random otis (here or would like to thank you! I failed solution), such a failure to check the motor of the Earth wire is loose. According to the information that really is the Earth wire is loose, tighten it seems after fault elimination or otis 's!!! engineer who experience old Ah, or else I go looking for reasons why Ah!!!

Fault 55: T40 elevator operation for 10 years, and suddenly one day lift appears uneven layer of phenomena, the IPU, IPD, DZ sensors and specially plates are moving too, been replaced in the same invalid DMCU, finally found control cabinet earthing terminal there are a few loose, tighten the elevator maintenance after normal. not only electrical components must bear line, Earth wire to tighten.

Fault repair 56: I recently had a 3100 elevator symptom is: from the top floor of 8 layers to the layers under sometimes elevator show from 8 layers quickly becomes 1 layer, Elevator emergency stop in 7 layers, former la RAM just fine, but the old, then checked the results found that the following cable 2LS, multimeter amount cable more than 200 of resistance, after the change has no longer appears.

Failed 57: otis3200 elevator, symptoms, no elevators do not run, no outbound, the room within the selected fault recording is DBD entry errors, clean up the UD relay 21.22-contact, the contact points, LB relay 21.22 UDX41.42-contact, the fault persists, the amount after the multimeter, found RF1 rectifier capacitance aging, the output voltage is not enough, after replacing capacitor 30V.

Failed 58 (debug encounter): GEN2 elevators each power power-TCB (M-1-2-1) failed: 0600SPB-Alert standby lock staircase time slightly longer, occasionally the panic, M-1-2-1 faulty records: 0302Door-Bridge0304DOL: alw.on. TCB fraternities DOL light flashes, the plugin to insert, self-learning, temporary solution; light curtain from 605 to 607.

Fault 59: owners reflect a 3100 elevator always appears inexplicable death ladder. to the scene see elevator panic but sometimes immediately up and running with TT enquiries LCBII. find the following failure: 0100, 0231. after suspected sedan handling maintenance fault signal of RS5. replacement lift is operating normally.

Fault 60: T2000 elevator operating normally, the door to normal after leveling, shut the door, when only forced to close button is not available, the light being normal, controlled door machine parameters normally COPY from new, MC Board after the closing film.

Fault 61: T40H, SGB plate no electricity, but the line is good. But that is not displayed, then SGB down clean, change to another lift can be used. Contact is not good, dust caused.

Fault 62: France 2000 elevator. no people inside, the old in the attic-recoil, 9/f, if someone teach-compartment, there would not be out of this problem, check the hash, steel, oil found too many, after cleaning.. ok.

Fault 63: 3200 lift, from the first floor when the lift to second floor flat floor area, lift occurs after the emergency stop, can stop-out slow, but cannot get the express train. The elevator up to the first floor, recovery express run, but when you run to the second floor flat floor area, lifts and an emergency stop, Zhou and villages. After checking, 1LS damaged, replace, the lift is complex.

Fault 64: Theo OH-CON (SPB + LCB2 + SIEI), sometimes stop to lift a floor fixed ladder, you cannot enter instruction. use TT view, as a DTO. examination hall doors are no problem-this failure frequency of about half a month. After replacement door signal cable, Elevator back to normal.

Fault 65: T60 elevator, elevator to uplink, downlink cannot start, contactors, also as the primary contact for after enquiries, contact a phase broken, this situation has occurred on many occasions, at attention. This failure by wyde provides. The automatic door closing time OTIS2000VF adjustment ~ today a landlord that elevator automatic closing time is too long (to open the door, not by the door button) for a long time to shut this is minor problems many people do not care about, here to tell some of the friends do not know the parameters in OC have CC-DT (car button) and HC-DT (outbound button) closing time is queried.Seconds of .40 and 4 seconds. ~ the elevators original time parameter is 80, elevator to 8 seconds before the door after changing back 40-, and four seconds to close the door.

Fault 66: T-3100R, ladder in a layer, no fast, slow, pull-in, release OP repeatedly. Go to maintenance workers, has changed frequency converter, motherboard LBII .... According to RF1 plate electrolysis leakage, normal replacement ladder. Inspiration: handling failure should carefully check all levelspoint pressure, blind hands-on easy walk to many detours!!!

Fault 67: T-3100 ladder up to the top speed changing, suddenly stop, and then return to the base station. According to the magnetic stripe on the exchange rate between the slit (7 mm or so), repaired staircase.

Fault 68: T-3 ladder after power on, power on the trip with moving. According to brake resistance after blowing, get a new stair properly. This failure by gaoyuzhou provides.

Fault 69: XIZIOTIS, STAR/616G5/LCBII. Occasional closed after starting, frequency converter displays the DBD protection fault. Power outage and then resume normal transmission, elevator. After frequent the same fault, related contacts, replace the SW1, SW2, DFC, BY, UD. Having a tough time fault reproduce, investigation discovery in SW1.SW2 of auxiliary contacts loop has a threaded BY long closed guide point, which is not on the original diagram. Is artificial added (perhaps to brake lines added). After its demolition, run half year didn't make this type of failure. But another similarly elevator without such failures. Strange? please insert make moves!

Fault 70: Xizi stopped in Gen2 elevator for any 1, 2, between the layers. Because emergency rescue operation breakdown, ladder can't move. TT: brake switch failure, check the climb without DC24V, well road (seatbelt OH) found out the result of long-term insurance socket void received the thermal deformation and fracture. Fix elevator properly. This failure is part of the fetus, colleagues note!!!. The other cannot be taken with a grain of salt TT: Oh.

Fault 71: OTIS3100, safety circuits, display, are fine. Outbound in selected, are invalid. Could not repair, car top station two talents to downlink. According to the preliminary charge converter blowing a resistor, the resistance of the merger, with similar parameters resistance instead. Elevator normal so far. The failure only touched once!

Fault 72: ever heard of the elevator in between the two layers are automatically opened the car door, there's no fear of passengers. I do not believe that the previous repair a fault, it is the emergence of this phenomenon. 3100 elevator, the runtime stops in between the two-story building, automatic door, passengers face well road, the end result is a car top of RS14 broke a piece, like car top junction box following the piece, replaced correctly. Is the handle of door signal board DCSS5. Random signal to the door. Thus, serial communication shortcomings not small, parallel communication signals to true.

Fault 73: one TOEC-3 elevator, owners reflect every morning when you open the door to close open staircase are in place, you need to force the door after outside in place, work is normal, and full-day are OK, maintenance personnel continually examine three days, the roots are no fault found, finally found a portal crane carbon brush card resistance, resulting in poor contact, restored to normal.

Fault 74: 3100R2 nuclear AODA door no display, check for door circuit board power supply section 51 European resistance destroyed, replaced the normal resistance door.

Fault 75: the door is closed are not T-40 place! check door resistance voltage normal normal!! check found motor brush after tightening loose!.

Fault repair of yesterday 76: T-40 elevator is 12/12 the elevator down to the 6th floor! there is no coherent jitter! 1/f, basic in 7/8 around the lift under no fault logging!! after checking is adjusts the machine fault! incorrectly, causing the wire rope traction wheel wear and bearing severe! wire rope shall not, in my first ropes before oil clean! adjust tightness of wire rope, the basic no fault! a few days to swap big wheel/rope/to do not necessarily come also appears this fault! I lift this line soon! if you say is wrong oh please don't laugh at me! my friends can also be valuable comments!

Fault 77: multiple Xizi STAR with Yaskawa inverter frequent OC overcurrent protection, SC burn occurs, then check the module main power is 14KW and inverter is only 9. 5KW do not match, then the manufacturers after reconstruction.

78: 3100LCBII elevator malfunction, failure, squatting, restore normal functioning, but some time later 10 appears where the missing issue, and then squatting, check individual wells road signal all normal, and then look inside the relay State control cabinet, LVC in failure, leading to relay release LV1, LV2 relay does not suck, check the LVC lines with no exception, LCBII plug plug it in again after fault disappears, suspected bad, adjust the plug plug back in operation after no exception.
Fault 79: 3100 elevator sometimes appears lost location of faults, the check, when the elevator from the ground floor of the top running a 100 per cent at fault occurs, check the wells road signal all normal, really can not find the reason, you will be well road OVF20 learning, learning revealed that failure is not in the event of a suspected chip data error, because learning after leveling accuracy is not an exception.
