2 ප්රධාන ලක්ෂණ

• Automatic Triple Reclosing: The device attempts to reclose three times with delays of 10 seconds, 60 seconds, and 300 seconds after a trip. If a successful reclosure occurs (stable operation for over 15 minutes), the fault is considered cleared, and the reclosing counter resets. Three consecutive reclosing failures result in a permanent lockout, requiring manual intervention.
• Type A Protection: Provides comprehensive protection against both AC sinusoidal residual currents and pulsating DC residual currents, enhancing safety in modern electrical installations.
• Manual and Automatic Mode Switching: Supports easy switching between automatic and manual recloser modes, offering flexibility in operation and maintenance.
• Manual Lockout Function: Allows for manual locking of the recloser function, which is crucial for safety during maintenance or when a persistent fault requires investigation.
• නායකත්වය විදහා: An integrated LED display provides real-time visual feedback on the device's operational status, including countdowns during reclosing attempts and fault indicators.
• Dry Contact Control: Features 6 contacts for external control, including Normally Closed (CLOSE), Normally Open (OPEN), Common (COM), L pole, and N pole connections. These contacts support a nominal voltagAC 100-240V හි ඊ.
• පුළුල් යෙදුම: Specifically designed for diverse environments, making it suitable for use in residential homes, commercial establishments, specialized industrial settings, and integrated smart home systems.

4. මෙහෙයුම් උපදෙස්

4.1 බල ගැන්වීම සක්‍රිය / අක්‍රිය කිරීම

To power on the device, ensure the main switch or lever is in the 'ON' position. To power off, move the switch or lever to the 'OFF' position. Always ensure the load is disconnected before powering off for safety.

4.2 Automatic Reclosing Function

In automatic mode, if an electrical fault causes the device to trip, it will initiate a sequence of up to three reclosing attempts. These attempts occur with specific staggered delays:

• First Attempt: තත්පර 10 කට පසුව.
• Second Attempt: After 60 seconds (if the first failed).
• Third Attempt: After 300 seconds (if the second failed).

If a reclosure is successful and the device operates stably for more than 15 minutes, the system determines that the fault has been cleared. The reclosing counter will then reset, and the device will return to its initial operational state.

If three consecutive reclosing attempts fail (either the device is unable to reclose or it trips again immediately after reclosing), the device will interpret this as a permanent fault. In this scenario, the automatic reclosing function will be locked out, and manual intervention will be required to reset the device after the fault has been addressed.

4.3 Mode Selection (Manual/Auto)

The device allows users to switch between automatic and manual recloser modes. Use the designated switch or button on the device to select the desired mode. In manual mode, the automatic reclosing function is disabled, providing direct control over the circuit breaker's state.

4.4 Manual Lockout

A manual lockout function is available to intentionally prevent automatic reclosing. This feature is particularly useful during maintenance procedures or when a persistent fault requires thorough investigation, ensuring the circuit remains open until manually reset. Consult the device's physical controls for engaging this function.

4.5 LED සංදර්ශකය

The integrated LED display provides clear visual feedback on the device's operational status. Observe the display for indicators such as countdowns during reclosing attempts, fault codes, or the current status (e.g., 'ON' or 'OFF').

5. නඩත්තු කිරීම

The TONGOU TOSAR-RD4A-2-40-003 is engineered for reliable operation with minimal maintenance requirements. However, periodic checks are highly recommended to ensure optimal performance and continued safety.

• දෘශ්‍ය පරීක්ෂාව: Regularly inspect the device for any signs of physical damage, such as cracks, discoloration, or loose connections. Ensure all wiring terminals are secure.
• පරීක්ෂණ බොත්තම: Periodically press the 'TEST' button (usually labeled 'T' or 'TEST') to verify the RCD's tripping mechanism. The device should trip immediately upon pressing the button. If it does not, the device may be faulty and requires professional inspection or replacement.
• පිරිසිදු කිරීම: Keep the device free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquid cleaners, solvents, or abrasive materials, as these can damage the device.

Always disconnect power to the circuit before performing any maintenance, inspection, or cleaning to prevent electric shock.

6. දෝශ නිරාකරණය

If the TONGOU TOSAR-RD4A-2-40-003 trips frequently or fails to reclose as expected, consider the following troubleshooting steps:

• නිතර පැකිලීම:
  • Temporary Faults: The auto-reclosing function is specifically designed to manage temporary or transient faults. If the device recloses successfully after a short delay, the fault was likely momentary and has cleared itself.
  • Persistent Faults: If the device trips and fails to reclose after three attempts (leading to a lockout), this strongly indicates a persistent electrical fault. This situation requires immediate investigation by a qualified electrician to identify and rectify the underlying cause, such as a faulty appliance, damaged wiring, or insulation breakdown.
• Failure to Reclose:
  • Check the LED display for any error codes or specific indicators that might provide clues about the failure.
  • Ensure the device is not inadvertently in manual lockout mode.
  • If the device is locked out after three reclosing failures, a manual reset will be required once the electrical fault has been completely cleared and verified safe.
• බලය නැත:
  • Verify that the main power supply to the RCD is active and not interrupted.
  • Check any upstream circuit breakers or fuses in your electrical panel to ensure they have not tripped.

Do not attempt to repair the device yourself. For any issues beyond basic troubleshooting, or if you are unsure about the cause of a fault, contact a qualified electrician for professional assistance.
