6. Troubleshooting
This section addresses common issues you might encounter with your Telwin Dynamic 520.
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit does not power on. | No main power supply; faulty power cord; internal fuse. | Check power outlet and cord. Consult a qualified technician if the issue persists. |
| Battery not charging. | Incorrect battery connection (polarity reversal); battery deeply discharged; incorrect voltage selection; overload protection activated. | Verify correct polarity. Ensure battery is not excessively discharged. Select correct 12V/24V setting. Allow unit to cool if overload protection is active. |
| Vehicle not starting with Quick Start. | Battery too weak; poor connections; engine issues unrelated to battery. | Ensure strong, clean connections. Allow battery to charge for a few minutes before attempting start. Consult vehicle mechanic if engine issues are suspected. |
| Overload protection activates frequently. | Attempting to charge/start a battery too large for the unit; short circuit in connections. | Ensure battery capacity is within the unit's rated reference capacity (20-1000 Ah). Check for short circuits. |
