Using the MC TT check failure record 2703, DB failure record INVERTEROCT, checkUDX relay contact normal, control cabinet wiring pile head normal motor, motor coil resistance in normal, temporarily unable to isolate the fault, then consider if brake under normal circumstances you cannot let go of, PVT not properly can also cause trouble, check brake properly, PVT check found plug welding line has a loose, welding fine after repairing malfunctions.

Fault 39 TOEC2000vf elevator, each time reset open once or twice they crashed and press repair downlink, instead of the elevator is not falling, converter displays a fault logging, upon inspection revealed a brake contactors of a small plastic card break in it, remove the clear after loading, the fault elimination.
Failure to run 40 T-40 elevator maintenance, Express has addressed after the car down the ladder handling results: L2 contact virtual even replaced the normal
Failure to display in the top level 41 elevators at the first floor of the result: 1LS circuit breaker

Barrier 42: E311 multiple elevators often panic phenomenon [result: control cabinet of all relay clean repair, serious corrosion after the replacement of contacts, greatly reduce the symptoms.

Fault 43: a OH-CON elevator (LCB2 + AMCB + SIEI), Elevator halls external display "??" The cycle of the first layer to the top from the top to be addressed at the first floor. Through observation, found LCB2 Board DZ no lights, check a flat layer optical damage worse leveling photoelectric, Elevator back to normal.

Fault 44: a OH-CON elevator (LCB2 + AMCB + SIEI), Elevator halls external display "??" The lift can be used for maintenance of the normal operation, cannot ping layer. INS lamp always, investigation, inspection and repair signal input to AMCB plate and LCB2 plate are OK. INS relay is working properly, all lines have not found any problems. Replacing the control cabinet RS5, Elevator back to normal.

Fault 45: 3200 elevator stopped a floor door outbound blinking, do not respond to call signal.According to the presentAs should be the DTO fault, but found drivers and independence are OK, use TT by MCB plate control door switch normal, suspected OC Board panic, reset normal

Fault 46: xo-star elevator (OVF30 converter + RCB2 + MCB2). Elevator all outbound flashing, lift up and running, all floors each answer. Carefully inspect outbound, found a floor a capacitor RS5 plate, replaced later yellow, Elevator back to normal. This failure by otismakui provides.

Fault 47: TOCE3 elevator, Elevator stopped on the top floor without display door always on, off electricity and then sent back to the elevator will close after running the command control cabinets in A1 contactor will suck but not closing down contactor, check the downlink contactor coil Circuit found that the uplink contactor support contact. This failure by cza. XIZIOTIS, OH5000 (lcb2amcb1siei) Elevator always off. To the site always appears lost position, a reset is normal after the elevator. But occasionally appear again photo has been replaced. Changed line. Are not resolved. After considering this is observation elevator suspected sunlight. The photoelectric switches into permanent magnet switches. The elevator runs a month out.

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!!!
