During the operation of the OTC DAIHEN Welding Robot, if the system experiences abnormalities such as synchronous welding execution failure, abnormal distance to recording point, sub-mechanism setting conflict, or material temperature out of limits, the teach pendant will usually display a hardware and control-level alarm in the 2784 to 2824 range. If these faults are not investigated promptly, they may cause serious operational safety hazards or damage peripheral devices.
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., 2784), to accurately obtain troubleshooting and processing suggestions.
I. OTC Robot Alarm Code Real-Time Quick Reference Table (2784-2824)
| Alarm Code | Fault Phenomenon | Fault Cause Analysis | Countermeasures & Solutions |
|---|---|---|---|
| 2784 | Synchronous Welding Not Executed | Hardware parameter configuration conflicts occurred, such as no welding gun connected, the same welding machine specified, welding gun not in the unit, or mixing servo and air welding guns. | Check the system hardware configuration list, modify the corresponding welding gun/welding machine assignment number, and then reset the exception. |
| 2785 | Welding Point Distance from Record Point is Too Far | The spatial distance between the actual action welding point calculated in the program and the originally set recording point exceeds the allowable safety range. | Check parameters such as servo welding gun contact check, tool constant, contact tip consumption, and welding gun bending to avoid conflicts, and then reset. |
| 2800 | Mechanism Not Installed | Attempted to execute the install mechanism function in the program without physically connecting the external mechanism, or the sub-mechanism input signal line is disconnected. | The physical mechanism and signal line must be connected properly before using the install mechanism function, and then reset the exception. |
| 2801 | Sub-Mechanism Cannot Be Selected | More than 2 sub-mechanism input signals in the control system are set to ON at the same time (logical conflict), making it impossible to make a single choice. | Troubleshoot and correctly input a single sub-mechanism input signal before using the install function, and then reset the exception. |
| 2802 | Mechanism Number Incorrect | In the mechanism switching or calling program, a mechanism number that the system prohibits changing or that does not exist was incorrectly selected. | Check the logic of the job program, correctly set the mechanism number allowed to be called, and then reset the exception. |
| 2803 | Installed a Different Mechanism | During the system self-test, it was detected that the currently installed physical mechanism differs from the mechanism model specified in a step of the program. | Check the mechanical replacement record, modify the job program to match the current real physical mechanism, and then reset the exception. |
| 2804 | Mechanism Change Conflict Occurred | The system attempted to force a change function on a mechanism being used by other system devices or background processes. | Modify the timing of the program logic to avoid conflicts caused by resource preemption, and then reset the exception. |
| 2805 | Mechanism Number Incorrect | Similar to code 2802, a mechanism number parameter that cannot be changed or is unauthorized was selected in the function configuration. | Correctly configure the available mechanism numbers in the system settings menu, and then reset the exception. |
| 2823 | Material Temperature Exceeded Upper Limit | The thermal sensor of the external system detected that the temperature of materials such as sealing/coating has exceeded the set upper limit. | Check the working status of the external material heating/temperature regulator, and reset the exception after the temperature drops to the safe zone. |
| 2824 | Material Temperature Exceeded Lower Limit | The thermal sensor of the external system detected that the temperature of materials such as sealing/coating has fallen below the set lower limit. | Check the working status of the external material heating/temperature regulator, and reset the exception after the temperature recovers to the normal range. |

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.
