- Ensure the lid is securely fastened at all times to maintain its rainproof integrity.
7. Otkrivanje problema
If your Intermatic PX300S transformer is not functioning as expected, refer to the following common issues and solutions:
| Problem | Mogući uzrok | Rješenje |
|---|---|---|
| No power output to lights | Overload detected by internal protector | Disconnect power, wait 15 minutes for reset. Reduce load or fix short circuit. |
| Svetla su prigušena | Netačan voltage tap selected or long cable run causing voltage drop | Potvrdite tačan voltage tap (12V, 13V, 14V) for your setup. Consider using a higher voltage tap or thicker gauge wire for longer runs. |
| Transformer humming loudly | Normal operation (slight hum) or loose mounting/components | A slight hum is normal. Ensure the transformer is securely mounted. Check for any loose internal components (qualified personnel only). |
| Enclosure shows signs of rust/corrosion | Exposure to harsh elements or damaged paint | While designed to resist oxidation, extreme conditions can affect it. Clean and apply rust-inhibiting paint if necessary. Ensure lid is sealed. |
