The "Xizi Otis Elevator Manual UPD" refers to technical documentation for the ACD2 (or ACD2-MRL)
Place a balanced load into the car (approximately 45% of the rated capacity) for calibration accuracy. Press the CHCS (Cancel Hall Calls) button. Enable DDO (Disable Door Operation).
The manual provides step-by-step flowcharts: "If OC1 occurs > Check motor continuity > If OK > Check IGBT module > If OK > Replace UPD control board." xizi otis elevator manual upd

Modern Xizi Otis units rely on sophisticated control interfaces detailed in their technical manuals:
| Code | Fault Name | Likely Cause & Manual Solution | |------|------------|--------------------------------| | OC1 | Overcurrent at acceleration | Short circuit in motor winding. Check insulation resistance (manual page 4-12). | | OC2 | Overcurrent at deceleration | Regenerative overload. Add braking resistor or adjust decel time (F02). | | OV1 | Overvoltage | Mains input too high or decel too aggressive. Measure input; increase F02 by 0.5 sec. | | UV | Undervoltage | Phase loss on R, S, T input. Check main contactor and fuses. | | OL | Overload | Mechanical jam in guide rails or door lock. Reduce counterweight ratio per manual. | | Encoder Fault (E.Enc) | Feedback loss | Broken encoder wiring or shield grounding issue. Manual shows pinout to test. |
