Built to withstand high-traffic industrial use, featuring dust-resistant housing and gold-plated contacts for long-term signal reliability.
and the general inverter, specifically for XO-STAR and OH5000 models. It manages run sequences, parameter adjustments (speed/leveling), and fault diagnostics.

Xizi Otis Elevator Manual Fixed: The Ultimate Troubleshooting and Repair Guide
Many manual fixes require fine-tuning physical adjustments rather than simply replacing electronics. Mechanical Brake Adjustment Manuals for these systems are often found on
The elevator has lost its position tracking or failed to detect the leveling magnets at a specific floor. Manual Fix:
| Fault Code | Meaning & Common Causes | Troubleshooting Steps | Related Systems (Documentation) | | :--- | :--- | :--- | :--- | | | OpMode- / DBSS fault : Drive part malfunction causing OCSS (Operation Control Subsystem) inoperability. Often appears in systems using LCB-II , TCBC , or GECB boards. | Check the frequency converter’s internal error logs for additional clues. A 0100 fault often points to a deeper issue. | LCB-II , TCBC , GECB , OH-CON6423 | | 0102 | OpMode DTC : Door fails to close within set time (missing DCL, DFC, or DW signal). | Inspect the door lock circuit, check the locking hook for abnormalities, and verify the door contact gap. Cleaning guide rails and checking the door motor or encoder are also common fixes. | LCB-II | | 0103 | OpMode DTO : Door fails to fully open within set time (missing DOL signal). | Check for physical obstructions, test the door operator belt and motor, and verify the DOL limit switch. | LCB-II , MCSS , OH-CON6423 | | 0201 | Corr. Run : A correction run is in progress. While often a normal resetting operation, it can be triggered by a fault. | If persistent, check the frequency converter‘s real-time status. An intermittent internal reset can trigger a 0201 while the elevator is moving. | GECB , ACB2 | | 0231 | See notes below regarding OH-CON6423 case study. This often points to a drive fault. | This code often appears alongside 0100 and 0201 when a drive problem triggers a safety circuit interruption. A 0231 fault should prompt a deep investigation of the drive‘s health and behavior. | ACB2 | | DCP | Delayed Car Protection : Car unable to respond to calls (e.g., door forced open). | Investigate the door lock (DCL, DFC, DW) and safety circuit. A recurring DCP fault may point to an intermittent issue with the LCB-II board’s ability to reset. | LCB-II | | Common Bus Faults | SIO MESSAGE FRAMING ERROR , SIO TIMEOUT ERROR , RSL sync loss, CANErrW . | Check serial communication wiring, inspect for loose connections, verify termination resistors, and test for electromagnetic interference (EMI). Restarting controllers may resolve transient errors. | OH-CONB603 ( GECB ), OH-CON6423 | Manual Fix: | Fault Code | Meaning &
Find the main power switch () and flip it to the OFF position.
If the system fails to clear errors after a reset, you must manually address the specific mechanical or electrical root causes detailed below. Door Interlock and Gate Switch Faults
Before performing repairs, verify the elevator's current state using the control panel's display.
