5. অপারেটিং নির্দেশাবলী
5.1 চালু
- After ensuring all connections are secure and correct, switch on the main AC power supply to the unit.
- The "ON" LED indicator on the front panel should illuminate, indicating that the power supply is active and providing output voltage.
5.2 স্থিতি সূচক
- এলইডি চালু: Illuminates when the power supply is receiving input power and operating normally.
- OVERLOAD LED: Illuminates if the output current exceeds the rated 2.5A, or if a short circuit is detected on the output.
6. রক্ষণাবেক্ষণ
The FERMAX 4825 power supply is designed for reliable, long-term operation with minimal maintenance. Follow these guidelines:
- পরিষ্কার করা: Periodically clean the exterior of the unit with a soft, dry cloth. Do not use liquid cleaners or solvents. Ensure the unit is powered off before cleaning.
- বায়ুচলাচল: Ensure that the ventilation openings are not obstructed to allow for proper air circulation and cooling.
- সংযোগ পরীক্ষা: Occasionally check all wiring connections to ensure they remain tight and secure.
7. সমস্যা সমাধান
- No "ON" LED illumination:
- Check if the main AC power supply is connected and active.
- Verify the input wiring (N, L) is correct and secure.
- "OVERLOAD" LED illuminates:
- This indicates an overcurrent condition or a short circuit on the 24V DC output or connected DUOX Plus bus lines.
- Immediately disconnect the main AC power supply to the unit.
- Inspect all connected DUOX Plus equipment and wiring for short circuits or excessive load.
- After resolving the issue, wait approximately one minute before reconnecting the main AC power supply to allow the electronic fuse to reset.
- If the problem persists, the connected equipment may be drawing too much current, or the power supply itself may be faulty.
- ভলিউম নেইtage / Sin Tensión / Nicht Spannung:
- This label on the unit indicates the absence of voltage. If the "ON" LED is off and there is no output, refer to the "No 'ON' LED illumination" troubleshooting steps.
