6. Troubleshooting
If you encounter issues with your VEMER VE792000 TMS 24/36 power supply, refer to the following troubleshooting guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| No blue LED indicator, no output voltage. | No input power, incorrect wiring, internal fault. | Check input power supply and connections. Verify wiring against the diagram. If problem persists, the unit may be faulty. |
| Blue LED is on, but no output voltage or incorrect voltage. | Output wiring fault, short circuit on output, overload condition. | Check output wiring for loose connections or short circuits. Disconnect load to check if output voltage returns. Reduce load if overloaded. |
| Unit repeatedly shuts down or cycles. | Overload, short circuit, or overheating. | Check for overload or short circuit on the output. Ensure adequate ventilation and ambient temperature. |
If troubleshooting steps do not resolve the issue, contact VEMER technical support. Do not attempt to repair the unit yourself.
