5. Instrucciones de funcionamiento

The DEWIN G2R 63A 2P ATS supports both automatic and manual operation modes.

5.1 Modo automático

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

• Set the 'Auto/Manual' switch to 'Auto'.
• The indicator lights (I and II) will show which power source is active.
• The 'Load ON' indicator will illuminate when power is supplied to the load.

5.2 Modo manual

To manually switch between power sources:

1. Set the 'Auto/Manual' switch to 'Manual'.
2. Use the operating handle to physically switch between position I (Common Power) and position II (Backup Power).
3. Ensure the desired power source is selected and the corresponding indicator light is on.

6. Mantenimiento

The DEWIN G2R 63A 2P ATS is designed for reliable operation with minimal maintenance. However, periodic checks are recommended:

• Inspección visual: Inspeccione periódicamente el dispositivo para detectar cualquier signo de daño físico, conexiones sueltas o sobrecalentamiento.
• Limpieza: Keep the device free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquids or abrasive cleaners.
• Comprobación de terminal: Periodically verify that all terminal screws are tight to prevent arcing and ensure good electrical contact.

Desconecte siempre la alimentación antes de realizar cualquier mantenimiento.

7. Solución de problemas

If you encounter issues with your ATS, consider the following common problems and solutions:

• No hay energía para cargar:
  - Check if both common and backup power sources are active.
  - Verify the 'Load ON' indicator is illuminated.
  - Ensure the ATS is in 'Auto' mode or manually switched to an active power source.
• Failure to Transfer Automatically:
  - Confirm the 'Auto/Manual' switch is set to 'Auto'.
  - Check the status of both power sources using their respective indicator lights.
  - If the issue persists, consult a qualified electrician.
• Overheating or Unusual Noises:
