【 Weak current College 】 OTIS Otis Elevator failure highlights 100 cases (4)---Power By 【 China power house network 】

Fault 81: 3100R2 in maintenance, off the main power and close power, often causing nuclear AODA door plate is damaged. Detection voltage 403V, check the control cabinet, found transformer input termination 380V-end, after grafting 399V side, no failure occurred. Recommended maintenance 3100R2, don't ruin the continuous frequently.


Fault 82: Theo 21VF elevator to spot slow cars can run, inverter indicates display * 047TT reality security company, MCSS onboard display properly. Safety circuit encoder lines are normal. In the maintenance of State press and hold down the button has the electric motor. The problem is brake cannot open, check brake switch normal brake contactors also sucks. Weight without brake coil resistance. Finalize the brake coil damage. Replacement properly.

Fault 83: Theo FO elevators ACB-2BRDS gantry crane. The elevator can run but do not open the door to check the resistance of door panel door plate switch RS5 door seated signal is functioning, the last in a line of communication within the search found DC30V patchy, finally found a top connection box plug-ins are loose. After the new fastening.

Fault 84: LCB-IIAMCB2SIEI OH5000 configuration. Lift does not close the door to the scene is also not displayed within, the check finds that found on plug-ins plug RS5, code is passive. Fix to normal but after the show or not show the fire door, TT, turned out to be a significant damage to the RS5 plates burn marks. Replacement properly. But the elevator or cannot run. The original formation of the RS5 plate also broke (lock staircase) replaced correctly.

Fault 85: GN2 elevator door descendants to block the light curtain to panic, or seeing the DTC failures TT, or seeing the door status is found no change in LRD. The lookup parameters found LRD parameter values wrong change back to normal.

Fault 86: Configure FO the freight elevator, elevator door plate ACB-IIBRDS does not close the door or the door door motor injitter door resistance heating quickly. Check the switch in place good signal, RS5 replacement fault persists, there is resistance as measured by measuring the electrical resistance, and electrical and mechanical brush correctly, capacitor replacement fault persists. Finally replace door plate back to normal.

Fault 87: OH5000 (MRL) configuration LCB-IIAMCB2 gearless machine. Elevator operation after a break time always appears converter protection (overload), view the inverter host settings parameters found inconsistent with the host. Modifications done from the new host learning after the elevator runs without exception.

Fault 88: Theo model STAR configuration LCB-IIAMCB2SEIE13VTR host. Elevator cannot run, the engine room to play-based maintenance, climbing can only run a break time cannot run, plug in the TT, I found the 1LS misoperation enquiries line found control cabinet Plug one end has loose, tighten back to normal.

Failure 89: Theo model STAR configuration LCB-IIAMCB2SEIE13VTR host. To the scene of inverter protective (velocity anomaly) reset and elevator cannot run, replace the following lift after the encoder is running properly.

Failure 89: Theo model STAR configuration LCB-IIAMCB2SEIE13VTR host. To the scene of inverter protective (velocity anomaly) reset the elevator runs correctly but run a week after the recurrence rate anomaly. Check the encoder Circuit found that plug-in PIN process do not sometimes cannot conduction. Processed correctly.


Failure 89: Theo model STAR configuration LCB-IIAMCB2SEIE13VTR host. To the scene of inverter protective (contactor error protection) reset the elevator runs correctly but run time recurs after you modify the converter parameter protection.

Fault 90: Theo model STAR configuration LCB-IIAMCB2SEIE13VTR host. To the scene of inverter protective (overload) Elevator down to run properly. Each time you run up to the top level is an overload protection, frequency converter modify AMCB parameter after the elevator up and running.

Fault 91: Theo model STAR configuration LCB-IIAMCB2SEIE13VTR host. To lift properly, powered converter will not be able to enter the menu. Replace the inverter from the new lift up and running after debugging.

Fault 92: 300 elevators, 23/f, close the door has opened the door, displayed in Flash, to room playing INS shorted lock elevator is not running, the Terminal voltage 110V.2-1-3DFC lowercase, DBP relay 21/22 is damaged, replace it to another point on the back to normal.

Fault 93: GEN26/6 two parallel ladder, in normal running two elevators with emergency stop, check your power supply distribution Chamber found elevator C phase 380V power is low, at 350, check control cabinet phase sequence relay display undervoltage lacks protection, Elevator power normal elevator also work correctly!!!.

Fault 94: otis3200, cp4 tripping, identified as the brake coil burn, etc to get a new fault persists after that. Due to the dual switches, cp4w fractured all the way, discover the rectifier bridge pile of breakdown, replacement, and troubleshooting.

Fault 95: two parallel 3200, failure to B ladder cannot eliminate numbers, A normal, judgment the ladder for serial communication problem., or serial communication line is bad, the control cabinet serial communication connectors reseat it. troubleshooting. Sometimes the failure appears to be complicated, so long as the careful, is very easy to crash.

Failure 96: a T40-TNT Express downlink normal stop uplink starts. Slow uplink, downlink chenzhonggan significantly. The inspection found speed parts brake insurance have a burnt down. Replacement properly.

Fault 97: 3200, the lift to the first floor could not find the location, Room 213 observation elevator toFirst floor 1LS sometimes become small, after doing a child again emphasise learning lift properly.

Fault 98: Xizi Otis XO-STAR passenger elevator LCB-Ⅱ + LPB + Yaskawa inverter, the symptom as running floor missing, Elevator emergency stop, show the "?" The base station addressed after returned to normal, this phenomenon is incidental, two or three days or longer; or in the elevator door leveling close, immediately after the safety edge are flexible without jamming, light eyes are invalidated, forced to close after reverse base to return to normal, or is not in the entrance area of the door, when stopped escalator inspection judgements is leveling sensors work instability, replace the observation for a period of time after work. Failure to do this kind of sensors (leveling sensors of type bistable magnetic induction) performance is not very stable.

Fault 99: T40 elevator, cabin high 5 floor ground Ridge 1 m emergency stop, 10/f, outbound display. control cabinet fault display d., fault indicator SDPL lit. climbing can run unchanged, however, the inspection to PS plate fuse open circuit F2 to enable + 42V power circuit breaker replacement fuse. after normal.

Fault-100: T40 elevator door side, almost every layer of closed cabin appears after the call-number of fault, the fault is frequently adjusted close to last PCT time to slow down, the fault disappears. the failure by jiangwei provides. Troubleshooting 101: T-3 (Ningbo Xinda door) sometimes does not switch on the door, according to the normal switch relays pick-up, gantry crane and gantry crane plates are normal, gantry crane and gantry crane after discovery panels interface is bad, the replacement interface after normal
