5. การติดตั้งและเดินสายไฟ

The TOQ6-63PV is designed for Din Rail mounting. Follow these steps for safe and correct installation:

1. การติดตั้ง: Securely attach the device to a standard 35mm Din Rail within an appropriate electrical enclosure.
2. Power Source 1 (City Power) Connection: Connect the main utility power supply to the terminals labeled "City Power" (N2|A2). Ensure correct L (Live) and N (Neutral) connections.
3. Power Source 2 (PV Grid-connected) Connection: Connect the PV grid-connected power supply to the terminals labeled "PV Grid-connected" (N1|A1). Ensure correct L (Live) and N (Neutral) connections.
4. โหลดการเชื่อมต่อ: Connect the electrical load (devices to be powered) to the "LOAD" terminals at the bottom of the switch.
5. Phase Sequence: สำคัญ: The input power supply must be connected in the correct phase sequence. Refer to the diagram on the device for guidance.
6. ขันขั้วต่อให้แน่น: Use a screwdriver to securely tighten all screw-type terminals to prevent loose connections and potential arcing. Recommended torque: 2.5 N·m.

6. การดำเนินการ

The TOQ6-63PV offers both automatic and manual operation modes.

6.1. โหมดการทำงาน

• โหมดอัตโนมัติ: When the selector switch is set to "Auto", the device will automatically detect the presence and quality of both power sources (City Power and PV Grid-connected) and switch to the preferred or available source. Typically, it prioritizes one source (e.g., PV) and switches to the other (e.g., City Power) if the primary source fails or is out of specification.
• โหมดแมนนวล: When the selector switch is set to "Manual", you can manually select the desired power source using the toggle switch (I or II).
  • ตำแหน่งที่ฉัน: Selects Power Source 1 (PV Grid-connected).
  • ตำแหน่งที่สอง: Selects Power Source 2 (City Power).

6.2. ไฟแสดงสถานะ

• IU (Red LED): Indicates the status of Power Source 1 (PV Grid-connected). Lit when Power Source 1 is active.
• IIU (Green LED): Indicates the status of Power Source 2 (City Power). Lit when Power Source 2 is active.
• Load ON (Red LED): Indicates that power is being supplied to the load. Lit when the load is receiving power from either source.

7. การบำรุงรักษา

The TOMZN TOQ6-63PV is designed for minimal maintenance. However, periodic checks are recommended:

• การตรวจสอบภาพ: Annually inspect the device for any signs of physical damage, discoloration, or loose connections.
• ความแน่นที่ปลายสาย: Periodically check and re-tighten all terminal screws to ensure secure electrical contact.
• การทำความสะอาด: If necessary, gently clean the exterior of the device with a dry, soft cloth. Do not use liquids or abrasive cleaners.
• สภาพแวดล้อม : Ensure the operating environment remains within specified temperature and humidity ranges to prolong device life.

8 การแก้ไขปัญหา

If you encounter issues with your TOQ6-63PV, consider the following common troubleshooting steps:

• ไม่มีพลังงานในการโหลด:
  • Check if both input power sources (City Power, PV Grid-connected) are active and their respective indicator lights (IU, IIU) are lit.
  • Ensure the device is in "Auto" mode or manually switched to an active source in "Manual" mode.
  • ตรวจสอบว่าการเชื่อมต่อสายไฟทั้งหมดมีความปลอดภัยและถูกต้อง
  • Check for tripped circuit breakers upstream of the ATS.
• Device Not Switching Automatically:
  • Confirm the selector switch is firmly in the "Auto" position.
  • Check the status of both input power sources. The automatic transfer relies on the availability of both sources.
  • มั่นใจได้ถึงการควบคุมปริมาณtage (220V~) is present and stable.
• Overheating/Unusual Odors:
  • Immediately disconnect power to the device.
  • This indicates a serious fault. Do not attempt to operate the device. Contact a qualified electrician.

For issues not resolved by these steps, consult a qualified electrician or contact TOMZN customer support.
