Standard "fixed" procedures for these systems typically follow a sequenced approach: Preliminary Checks
Ensure the emergency stop button isn't engaged; if it was, release it and cycle the power to clear the fault. Mechanical & Hardware Fixes XIZI DO3000 Error Code Solutions | PDF - Scribd
5.2 Engage Manual Hold/Fixed Position
| Fault Code | Description | Likely Cause | Solution | | :--- | :--- | :--- | :--- | | | Safety Circuit Open | Safety string broken (pit, car top, or machine room). | Check safety switches (buffer, safety gear, emergency exit). | | 21 | Drive Fault | Inverter overload or hardware error. | Reset power. Check motor resistance and encoder wiring. | | 22 | Encoder Fault | Encoder signal lost or noisy. | Check encoder cable shielding and connections. | | 23 | Speed Deviation | Elevator speed does not match command. | Check brake opening; ensure brakes are fully lifting. | | 41 | Door Lock Fault | Door lock circuit is open. | Check hall door locks and car door locks. Clean contacts. | | 42 | Door Open Timeout | Doors failed to open within set time. | Check door motor, belt tension, and guide shoes. |
The safety chain is broken because the hoistway doors or car doors are not completely closed during running state. xizi otis elevator manual fixed
Faults often arise from parameter drift rather than hardware failure. Manuals guide you through verifying key parameters:
This comprehensive guide provides detailed information on the Xizi Otis elevator system. It is essential to follow the guidelines outlined in this manual to ensure the safe and reliable operation of the elevator. | | 21 | Drive Fault | Inverter overload or hardware error
The manual dictates that a broken safety chain is the most frequent cause of sudden stoppages. Check the voltage across the safety string terminals. If the safety chain is open, check the following physical switches: Pit emergency stop switch Car top stop switch Buffers and governor switches Slack rope safety switch Step 3: Inspect Door Interlocks
Toggle the car top inspection switch back to normal mode. Clear faults using the service tool. Limit Switch Error Hoistway Sensors | | 22 | Encoder Fault | Encoder signal lost or noisy
Note: To reset most "Fixed" faults, cycle the power or press the "Reset" button on the controller board.
Check motor thermal overload. Verify input voltage phases and check braking resistor continuity. Door Open/Close Timeout Door Operator
