EARUELETRIC EAATS-F-CS Dual Power Automatic Transfer Switch

1. Продукт бүтүп калдыview

The EARUELETRIC EAATS-F-CS is a PC class infrequent change-over switch designed for dual power systems. It features a two-station design, typically used for a common power supply (A) and a standby power supply (B). This switch is suitable for AC systems operating at 50-60Hz with a rated current of 6-80A.

Its primary function is to automatically switch to the backup power supply (B) when the main power supply (A) fails. This rapid conversion, occurring in less than 50 milliseconds, effectively mitigates disruptions caused by power outages, ensuring an uninterrupted power supply.

3. Коопсуздук маалыматы

Please read and understand all safety precautions before installation and operation to prevent damage to the device or personal injury.

• Тtage Шайкештик:
  • For 220V ATS units, do not use with a voltage 185V төмөн.
  • For 110V ATS units, do not use with a voltage 90V төмөн.
  Failure to observe these voltage limits may cause the coil to overheat and burn out.
• Кол менен иштөө: The switch cannot be manually operated when it is in automatic mode. Attempting to do so may cause the coil to burn out.
• Phase Sequence (4P ATS): For 4P ATS units, ensure the correct connection of the phase sequence. Incorrect phase sequence can lead to contact damage.
• Катушки коргоо: The control circuit ATS is immediately energized. After the changeover is completed, the internal switch will protect the coil in the control circuit. The coil is designed to operate normally at 85%~110% of the rated operating voltagд. Киргизүү томtage that is too low may cause the coil to overheat and burn out.

The EAATS-F-CS is designed for Din Rail mounting, utilizing a standard 35MM guide rail for easy installation in electrical panels.

Wiring Diagram and Component Identification

Refer to the diagram below for proper wiring connections and identification of components. Ensure all connections are secure and comply with local electrical codes.

• Common Power Supply (I): Connect your primary power source (e.g., city grid) to the terminals labeled 'I'. This includes the common power live wire and common power neutral wire.
• Backup Power Supply (II): Connect your secondary power source (e.g., PV energy, generator) to the terminals labeled 'II'. This includes the backup power live wire and backup power neutral wire.
• Жүктөө: Connect your electrical load to the 'LOAD' terminals. This includes the load closing indication and load output live wire.
• Electricity Indication: The device includes indicators for both common power supply and backup power supply to show which source is active.

5. Иштөө нускамалары

The automatic transfer switch offers two modes of operation: Manual and Automatic. The mode can be selected using the Manual/Automatic Changeover Switch on the device.

Автоматтык режим (AUTO)

• In 'AUTO' mode, the switch will automatically detect the presence of power from the common supply (I) and backup supply (II).
• If the common power supply (I) is active, the switch will connect the load to it.
• If the common power supply (I) fails, the switch will automatically transfer the load to the backup power supply (II) within 50 milliseconds, provided the backup supply is available.
• When the common power supply (I) is restored, the switch will automatically transfer the load back to the common supply.
• Маанилүү: Do not attempt to manually switch the grey button handle while in 'AUTO' mode.

Manual Mode (MANU)

• To operate the switch manually, first ensure the mode selection switch is set to 'MANU'.
• In manual mode, you can use the operation handle to switch between power sources I and II.
• Manual operation ensures the opening and closing performance of electrical operation, but there is no guarantee regarding the speed of operation, which could lead to excessive silver alloy loss over time.
• It is recommended to only use manual mode after all power has been cut off for inspection and maintenance. For normal operation, keep the selector switch in the 'AUTO' position.

6. Техникалык тейлөө

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

• Визуалдык текшерүү: Periodically inspect the switch for any signs of physical damage, loose connections, or discoloration due to overheating.
• Терминалдын тыгыздыгы: Ensure all wiring terminals are securely tightened. Loose connections can lead to arcing and overheating.
• Чаң жана сыныктар: Keep the switch free from dust and debris, which can interfere with its mechanical operation and heat dissipation. Use a dry, soft cloth or compressed air for cleaning.
• Кесиптик текшерүү: For critical applications, consider having a qualified electrician inspect the ATS annually to verify its functionality and safety.
• Электр энергиясын өчүрүү: Always disconnect all power sources before performing any maintenance or inspection on the switch.

7. Кыйынчылыктарды

If you encounter issues with your automatic transfer switch, refer to the following common troubleshooting steps:

• Switch Not Transferring:
  • Check if both common and backup power sources are active and within the specified voltage диапазону.
  • Ensure the switch is in 'AUTO' mode for automatic transfer.
  • Verify all wiring connections are correct and secure according to the installation diagram.
• Coil Overheating/Burnout:
  • Киргизилген том экенин ырастаңызtage for the ATS is within the acceptable range (e.g., not below 185V for 220V units or 90V for 110V units).
  • Avoid manual operation while the switch is in 'AUTO' mode.
• Жүктөө кубаттуулукту кабыл албай жатат:
  • Check the status indicators on the switch to see which power source is currently connected.
  • Inspect the load connections for any disconnections or faults.
  • Ensure the short circuit protection device (fuse) is intact and not tripped.
• адаттан тыш үндөр же жыттар: Immediately disconnect power to the unit and contact a qualified electrician for inspection. Do not attempt to operate the switch if you notice any unusual sounds or odors.

8. Колдонуучунун кеңештери

• Мезгил-мезгили менен тестирлөө: It's a good practice to periodically test the automatic transfer function by temporarily cutting off the main power to ensure the backup system engages correctly.
• Белгилөө: Clearly label your common and backup power sources at the breaker panel and near the ATS for easy identification during maintenance or troubleshooting.
• Кесиптик орнотуу: For optimal safety and performance, consider having the ATS installed by a certified electrician, especially if you are unfamiliar with electrical wiring.
