TOMZN TOQ3/2P Automatic Transfer Switch User Manual

1. บทนำ

This manual provides essential information for the safe and efficient installation, operation, and maintenance of the TOMZN TOQ3/2P MCB type Dual Power Automatic Transfer Switch (ATS). The ATS is designed to automatically switch between two power sources, such as a main utility supply and a backup generator or solar power system, ensuring continuous power to your load.

The TOQ3/2P is a voltage relay-based automatic transfer switch with integrated circuit breakers for protection. It supports both automatic and manual operation modes.

2. ข้อมูลด้านความปลอดภัย

คำเตือน: อันตรายจากไฟฟ้าช็อต การติดตั้งและบำรุงรักษาควรดำเนินการโดยบุคลากรผู้เชี่ยวชาญเท่านั้น

• Always disconnect power from both main and backup sources before installation or maintenance.
• ตรวจสอบให้แน่ใจว่าการเชื่อมต่อสายไฟทั้งหมดมีความปลอดภัยและเป็นไปตามกฎหมายไฟฟ้าในท้องถิ่น
• ห้ามใช้งานสวิตช์หากพบว่ามีความเสียหาย
• ตรวจสอบปริมาณtage and current ratings of the ATS match your application requirements.
• The device is designed for AC power sources.

5. การติดตั้ง

The TOMZN TOQ3/2P ATS is designed for fixed mounting. It does not fit standard DIN rails but has a mounting plate with holes at the corners for secure installation.

5.1 แผนผังการเดินสายไฟ

Refer to the following diagram for proper connection of the main power, backup power, and load.

1. Common Power Supply (Main): Connect the Live (L) and Neutral (N) wires from your primary power source to the terminals labeled 'L' and 'N' on the 'Common power supply' side (left side of the diagram).
2. แหล่งจ่ายไฟสำรอง: Connect the Live (L) and Neutral (N) wires from your secondary power source (e.g., generator, solar inverter) to the terminals labeled 'L' and 'N' on the 'Backup power' side (right side of the diagram).
3. โหลด: Connect your electrical load (appliances, circuits) to the output terminals labeled 'load' at the bottom of the switch.
4. Control Terminals (Green Block): The green terminal block in the middle is typically for control signals or status indicators. While it's possible to leave them unconnected for basic automatic transfer functionality, consult a qualified electrician for specific control wiring needs if you intend to integrate with other systems.

5.2 ฉบับtage ข้อควรพิจารณา

This ATS is designed for 220V (L+N 220V) systems. It may not work properly with 110V or 120V systems due to its internal motor and coils being rated for 220V. Ensure your power sources match the device's rated voltage.

6. การดำเนินการ

The TOQ3/2P ATS offers both automatic and manual modes of operation.

6.1 โหมดอัตโนมัติ

In automatic mode, the switch will detect the presence of voltage on the primary power source. If the primary source fails, it will automatically switch to the backup source. When the primary source is restored, the switch will automatically transfer back to the primary source. The transfer time is typically very fast, often within 1 second, making the transition unnoticeable for most equipment.

The ATS prioritizes the main input. If both main and reserve supplies are available, it will connect to the main supply.

6.2 โหมดแมนนวล

The device features a manual operation lever. In special circumstances, or for testing purposes, you can use this lever to manually switch between the common and standby power sources. Ensure the system is de-energized before attempting manual operation if you are unsure of the procedure.

7. การบำรุงรักษา

• Regularly inspect the ATS for any signs of physical damage, loose connections, or overheating.
• Ensure the area around the switch is clean and free from dust and debris to prevent overheating.
• The plastic housing is designed to withstand normal operating conditions and should not melt with proper installation and within specified ratings.
• For any internal repairs or complex issues, contact a qualified electrician.

8 การแก้ไขปัญหา

• Device not switching:
  • Check if both power sources (main and backup) are providing the correct voltage.
  • ตรวจสอบให้แน่ใจว่าการเชื่อมต่อสายไฟทั้งหมดมีความปลอดภัย
  • Verify the ATS is in 'Auto' mode if automatic switching is desired.
• Overheating or melting plastic:
  • This indicates an overload or improper installation. Immediately disconnect power.
  • Ensure the total load current does not exceed the 63A rating of the switch.
  • Verify proper wire gauge for the current load.
• เล่มที่เข้ากันไม่ได้tage:
  • The ATS is designed for 220V. Using it with 110V/120V may result in improper function or damage. Ensure your system voltage matches the ATS specifications.

9. เคล็ดลับผู้ใช้

• This switch is ideal for homes or small businesses with a backup generator or solar system, providing automatic power transfer during outagใช่
• It can be used to switch between two different main power sources, not just a main and a generator, provided the wiring diagram is respected.
• Users have reported reliable operation with fast switching times (within 1 second) during daily power outagใช่
• While the green terminal block can be left unconnected for basic functionality, it offers potential for advanced control or status indication if integrated by a professional.
