5. Operation

5.1 Manual/Automatic Operation

The ATS guarantees power generation and power failure performance during circuit operation. However, for manual operation, the performance cannot be guaranteed due to variations in power generation/failure speed or operator actions. Excessive silver alloy loss may occur during manual power generation and power failure.

• For Inspection and Maintenance: When all power supplies are cut off to check and maintain the operating system and contacts, pull the selector switch to the Manual position.
• Normal Operation: Under normal circumstances, keep the selector switch in the Automatic position.
• After Manual Operation: Once manual operation is completed, return the selector switch from the Manual position to the Automatic position.

7. Maintenance and Inspection

Regular maintenance ensures the longevity and reliable performance of your ATS. All maintenance and inspection procedures must be performed by professionals with all power supplies cut off in advance.

7.1 Maintenance Frequency

• First Maintenance: Within 6 months after initial use.
• Regular Maintenance: At least once a year.
• Harsh Conditions: Increase the frequency of maintenance and inspection in harsh installation environments.

7.2 Maintenance and Inspection Items

1. Cleanliness: Remove dust and dirt from the device.
2. Electrical Contacts: Check for deformation, damage, or burnt metal particles on and around the contact parts. Remove any such particles.
3. Contact Surface: Rust, acidification, and dust on the contact surface can lead to poor contact. Operate the device manually many times and measure the contact resistance if necessary.
4. Insulation Resistance: If the ATS has been exposed to long-term moisture or suspension, dry it before use. After cleaning, use a 500V megohmmeter to measure the insulation resistance between the normal supply, alternating power supply, load side bar, live parts, and metal plate. The insulation resistance should not be less than 10MΩ.

7.3 Storage

The ATS should be stored in an environment equivalent to normal working conditions, with appropriate dust-proof, moisture-proof, and collision-proof measures.

8. Troubleshooting (eWeLink App & WiFi)

If you encounter issues with your ATS, particularly regarding its smart functions, refer to the following common problems and solutions.

8.1 Device Appears Offline After Successful Addition

After adding the device, it typically takes 1-2 minutes to connect to the network. If it remains offline:

• Check Wi-Fi Indicator Status:
  • Blinks quickly once per second: Device is not connected to your Wi-Fi.
    1. You may have entered an incorrect Wi-Fi password.
    2. The device might be too far from your router, the signal too weak, or there's interference. Move the device closer to the router.
    3. The device cannot recognize 5G Wi-Fi. Ensure you are using a 2.4G Wi-Fi network.
    4. Mac address filtering might be enabled on your router. Disable it.
    5. If issues persist, try using another phone to open a personal hotspot and attempt to re-add the device.
  • Blinks quickly twice per second: Device is connected to Wi-Fi but not to the Internet.
    • Confirm your Wi-Fi connection network is stable and normal. Frequent blinking indicates an unstable network, not a product malfunction.
    • If the network is normal, power off and restart the device.

8.2 Factory Reset

If you need to change to a new network or resolve persistent issues, perform a factory reset:

• Press and hold the pairing button for 5 seconds until the LED indicator blinks twice. This resets the device and enters Bluetooth pairing mode again.

Figure: eWeLink App Interface (for reference)

eWeLink has integrated with mainstream AI platforms. To ensure users can quickly identify compatible platforms/smart speakers, manufacturers may print a "Works with AI" eWeLink logo on packaging or in the user manual. Smart products supporting eWeLink APP need certification from corresponding platforms before using AI voice platform logos.

9. User Tips

• Power Supply Configuration: For a 3-phase system with 1P (127V) + 1P (127V) + 1P NEUTRAL (0V), you would typically need a 3P (Three Pole) ATS model. Ensure the voltage rating matches your system (e.g., 120V AC).
• Professional Installation: Given the high voltage and critical function of this device, professional installation by a certified electrician is highly recommended to ensure safety and compliance with electrical codes.
