3. පිහිටුවීම සහ ස්ථාපනය
The ABB MCB-10 Contact Block is designed for front mounting onto compatible ABB control devices, such as contactors or pushbuttons. Follow these steps for proper installation:
- විදුලිය විසන්ධි කිරීම: Ensure all power to the main control device is disconnected and locked out according to safety procedures.
- සවි කිරීම: Align the MCB-10 Contact Block with the designated mounting slots on the front of the main control device. Gently push the contact block until it clicks securely into place. Verify that it is firmly attached and does not wobble.
- රැහැන් ඇදීම: Connect the control wires to the screw terminals of the MCB-10. The terminals are typically marked '3' and '4' for a Normally Open (NO) contact. Use appropriate wire gauges for the intended current. Ensure wires are stripped to the correct length and inserted fully into the terminals before tightening the screws firmly. Avoid overtightening.
- සත්යාපනය: After wiring, double-check all connections for tightness and correct polarity. Ensure no bare wires are exposed.

4. මෙහෙයුම් උපදෙස්
The MCB-10 is a passive component that functions as an auxiliary contact for a main control device. Its operation is directly linked to the state of the device it is mounted on.
- සාමාන්යයෙන් විවෘත (නැත) සම්බන්ධතාව: The 1 NO contact of the MCB-10 remains open when the main control device (e.g., contactor coil) is de-energized.
- සම්බන්ධතා වසා දැමීම: When the main control device is energized (e.g., contactor coil is activated), the mechanical action of the main device causes the MCB-10's NO contact to close, completing the auxiliary circuit.
- සම්බන්ධතා විවෘත කිරීම: When the main control device is de-energized, the NO contact of the MCB-10 returns to its open state.

5. නඩත්තු කිරීම
Regular maintenance helps ensure the longevity and reliable operation of the MCB-10 Contact Block. Always disconnect power before performing any maintenance.
- දෘශ්ය පරීක්ෂාව: Periodically inspect the contact block for any signs of physical damage, discoloration, or excessive wear.
- පර්යන්ත සම්බන්ධතා: Check all screw terminals for tightness. Loose connections can lead to overheating and intermittent operation.
- පිරිසිදුකම: Ensure the contact block is free from dust, dirt, and other debris that could interfere with its mechanical operation or electrical conductivity. Use a dry, soft cloth for cleaning. Do not use solvents.
- ක්රියාකාරීත්ව පරීක්ෂාව: If possible and safe to do so, verify the mechanical action of the contact block by observing its response to the main control device's operation.
Replace the contact block if any significant damage or malfunction is observed.
6. දෝශ නිරාකරණය
If you experience issues with the MCB-10 Contact Block, consider the following troubleshooting steps:
- Contact Not Closing/Opening:
- Verify that the main control device (e.g., contactor) is functioning correctly and actuating the contact block.
- Check for proper mounting of the MCB-10 onto the main device. Ensure it is securely seated.
- Inspect wiring for loose connections or breaks.
- අතරමැදි මෙහෙයුම:
- Tighten all terminal screws.
- Check for any debris obstructing the mechanical movement of the contact.
- Inspect for signs of arcing or pitting on the contact surfaces (only if safely accessible and power is off).
- අධික උනුසුම් වීම:
- Ensure the current flowing through the contact does not exceed its rated capacity (15 Amps).
- ප්රතිරෝධය සහ තාපය ඇති කළ හැකි ලිහිල් පර්යන්ත සම්බන්ධතා තිබේදැයි පරීක්ෂා කරන්න.
