6. Operating Instructions

The ATS switch supports both automatic and manual operation modes.

6.1 Automatic Mode

• Set the selector switch on the device to the 'Auto' position.
• In this mode, the switch will automatically monitor the common power supply (Source A).
• If Source A fails or becomes abnormal, the switch will automatically transfer the load to the backup power supply (Source B).
• When Source A is restored and stable, the switch will automatically transfer the load back to Source A.

6.2 Manual Mode

• Set the selector switch on the device to the 'Manual' position.
• In manual mode, the user can manually switch between Source A and Source B using the lever.
• Important: Manual operation must be performed carefully. Ensure the desired source is stable before switching.

7. Maintenance

Regular maintenance helps ensure the longevity and reliable operation of your ATS switch.

• Periodic Inspection: Annually, or more frequently in harsh environments, inspect the switch for any signs of wear, damage, or loose connections.
• Cleaning: Keep the device clean and free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquid cleaners.
• Terminal Tightness: Periodically check and tighten all terminal connections to prevent overheating and arcing.
• Functionality Test: Periodically test the automatic transfer function by simulating a power outage for Source A (if safe to do so).

Always disconnect power before performing any maintenance.

8. Troubleshooting

If you encounter issues with your ATS switch, consider the following common troubleshooting steps:

• No Power to Load:
  • Check if both Source A and Source B are active and providing power.
  • Verify all wiring connections are secure and correct.
  • Ensure the selector switch is in the desired position (Auto or Manual).
• Failure to Transfer Automatically:
  • Confirm the switch is in 'Auto' mode.
  • Check the control line connections for both sources.
  • Ensure the backup power source (Source B) is operational and providing stable power.
• Overheating:
  • Check for loose terminal connections.
  • Ensure the load current does not exceed the rated current of the switch (100A).
  • Verify adequate ventilation around the device.

If problems persist after troubleshooting, contact qualified technical support.
