During the operation of the OTC DAIHEN Welding Robot, if the system experiences problems such as sensor condition file error, starting point not detected, deviation and search range exceeded, the teach pendant will usually display a hardware and control-level alarm in the 5234 to 5243 range. If these faults are not investigated promptly, they may cause serious operational safety hazards or damage to core components such as the reducer.
To help on-site engineers and mechanics quickly locate problems, we have organized the diagnostic terminology from the official maintenance manual to provide you with the following intuitive fault quick reference table. We recommend using the search function, entering the error code (e.g., 5234), to accurately obtain troubleshooting and processing suggestions.
I. OTC Robot Alarm Code Real-Time Quick Reference Table (5234-5243)
| Alarm Code | Fault Phenomenon | Fault Cause Analysis | Countermeasures & Solutions |
|---|---|---|---|
| 5234 | Sensor Condition File Error | Error data was detected in the LSF or LSR file. | Check the contents of the LSF or LSR file, and then perform an exception reset. |
| 5235 | Sensor Condition File Does Not Exist | The specified LSF or LSR file does not exist. | Check the LSF or LSR file number, and then perform an exception reset. |
| 5236 | Sensor Exception | The sensor control device is abnormal. | Use WinUser to check the sensor status, and then perform an exception reset. |
| 5237 | Starting Point Not Detected | The starting point was not detected during ZF search. | Use WinUser to check groove recognition; increase the ZF maximum search range. Then perform an exception reset. |
| 5238 | Cannot Restart During Sealing Tracking | Cannot restart during sealing tracking. | The position and posture of the robot should not be modified, and then perform an exception reset. |
| 5239 | Exceeded ZF Deviation Range | The distance between the detected starting point and the ZF taught point exceeds the deviation range. | Check the detected position, modify (increase) the ZF deviation range parameter or program, and then perform an exception reset. |
| 5240 | Exceeded ZF Search Range | The robot moved outside the search range. | Modify (increase) the search range or program to correct the error, and then perform an exception reset. |
| 5241 | Exceeded ZT Position Deviation Range | The robot moved outside the position deviation range. | Check the target position, modify (increase) the ZT parameter or program to correct the error, and then perform an exception reset. |
| 5242 | Exceeded ZN Deviation Range | The set deviation exceeds the range. | Modify (increase) the ZN deviation or program to correct the error, and then perform an exception reset. |
| 5243 | Exceeded ZN Search Range | The robot moved outside the search range during ZN. | Modify (increase) the ZN search range or program to correct the error, and then perform an exception reset. |

When the robot frequently displays the above hardware-level alarms, and routine reset attempts are ineffective, do not forcefully pull the robot arm or repeatedly force restarts, so as not to cause secondary irreversible damage.
