• Manual Mode: Flip the red toggle switch to the 'Manual' position. In this mode, power transfer is controlled manually using the large rotary handle.

5.2. Manual Operation (if in Manual Mode)

To manually switch between power sources:

1. Ensure the red toggle switch is in the 'Manual' position.
2. Rotate the large white handle to the desired power source position. The red arrow on the handle indicates the currently selected source.

5.3. Indicator Lights

The ATS features several indicator lights to show its operational status:

• Common power supply: Indicates the main power source is active.
• Common closing: Indicates the main power source is connected to the load.
• Standby closing: Indicates the backup power source is connected to the load.
• Backup power: Indicates the backup power source is active.

6. Maintenance

Regular maintenance ensures the longevity and reliable operation of your ATS. Always disconnect power before performing any maintenance.

• Periodic Inspection: Annually inspect the ATS for any signs of physical damage, loose connections, or corrosion.
• Cleaning: Keep the unit clean and free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquid cleaners.
• Terminal Check: Periodically check all terminal connections to ensure they are tight. Loose connections can lead to overheating and potential failure.

7. Troubleshooting

If you encounter issues with your RWRAPS ATS, refer to the following common problems and solutions:

• No Power to Load:
  • Check if both main and backup power sources are active.
  • Verify the ATS is in the correct operating mode (Automatic or Manual).
  • Inspect circuit breakers or fuses for both power sources.
• ATS Not Transferring Automatically:
  • Ensure the toggle switch is set to 'Automatic'.
  • Confirm that the main power supply is indeed absent or below acceptable levels.
  • Check for any error indicators or unusual sounds.
• Overheating:
  • Ensure proper ventilation around the unit.
  • Check for loose connections at terminals.
  • Verify that the load does not exceed the ATS's rated current (125A).
