5. Иштөө нускамалары

The DEWIN ATS offers both automatic and manual operation modes.

5.1 Автоматтык режим

In automatic mode, the switch will detect the presence of the main power supply (Normal Power) and the backup power supply (Generator). If the main power fails, the switch will automatically transfer the load to the backup power. When the main power is restored, it will switch back.

• Set the selector switch to "Auto".
• The green "Load ON" indicator will illuminate when power is supplied to the load.
• The red indicator will show the active power source (I for main, II for backup).

5.2 Кол режими

In manual mode, you can manually switch between the main and backup power sources using the green handle.

• Set the selector switch to "Manual".
• Move the green handle to position "I" for main power or "II" for backup power.
• Ensure the load is disconnected before manually switching to prevent arcing.

6. Техникалык тейлөө

The DEWIN ATS is designed for reliable operation with minimal maintenance. However, periodic checks are recommended:

• Визуалдык текшерүү: Regularly inspect the switch for any signs of physical damage, loose connections, or overheating.
• Тазалоо: Keep the device free from dust and debris. Use a dry, non-abrasive cloth for cleaning. Do not use liquids.
• Терминалдын тыгыздыгы: Periodically check and tighten all terminal connections to ensure good electrical contact.
• Функционалдык тест: If safe to do so, periodically test the automatic transfer function by simulating a main power failure.

CAUTION: Always disconnect all power sources before performing any maintenance or inspection.
