Maintaining a Barrier Gate System to Prevent System Breakdown
Slide 2: 1. Earthing Down Conductors Resistance Value
- Fact: 90% of Barrier Gate Malfunction is due to poor Earthing System either lightning surges or an Electrostatic Discharge (ESD) occurs on PCB board. Proper earthing is crucial for system safety and stability, preventing electrical faults and ensuring system longevity.
- Prevention: Regularly measure and maintain low resistance values in the earthing down conductors to ensure effective fault current dissipation.
- Check Method: Use an earth resistance tester to measure the resistance value and ensure it remains within the acceptable range.
Slide 3: 2. Aging of Barrier Arm
- Fact: Over time, the barrier arm and its components, particularly the arm bracket, may weaken, leading to potential system failure or safety hazards.
- Prevention: Inspect the barrier arm regularly for signs of wear, particularly at the bracket position, and replace aging parts as needed.
- Check Method: Conduct visual inspections and manual testing of the barrier arm for any signs of deterioration or instability.
Slide 4: 3. Rubber Stopper Alignment
- Fact: The rubber stopper ensures the barrier arm stops at the correct position, indicating proper alignment and preventing mechanical strain.
- Prevention: Regularly inspect the rubber stopper for wear and ensure it is correctly positioned to align with the barrier arm.
- Check Method: Visually check the condition of the rubber stopper and test the barrier arm’s stopping point to ensure proper alignment.
Slide 5: 4. Spring Coils
- Fact: Spring coils are essential for smooth operation, absorbing shocks, and preventing the barrier arm from shaking during movement.
- Prevention: Inspect spring coils regularly for signs of fatigue or damage and replace them if they lose tension or become deformed.
- Check Method: Perform a visual and manual check of the spring coils to ensure they maintain proper tension and are free from rust or wear.
Slide 6: 5. Cable Management
- Fact: Proper cable management prevents short circuits and protects cables from exposure to moisture, which can cause system malfunctions.
- Prevention: Regularly organize and secure cables, ensuring they are not exposed to the elements or prone to damage.
- Check Method: Inspect cable routing and connections, looking for signs of wear, exposure, or potential for short circuits.
Slide 7: 6. Auto Close Function
- Fact: The auto-close function, controlled by loop detection sensors or traffic detectors, is crucial for smooth and automatic gate operation.
- Prevention: Regularly test the auto-close function to ensure sensors and detectors are functioning correctly, preventing unauthorized access.
- Check Method: Test the auto-close functionality by simulating vehicle presence and absence, ensuring the gate closes automatically and securely.
Slide 8: 7. Surge Protection Devices
- Fact: Surge protection devices safeguard the system from voltage spikes, either from push button signals or AC power cables, preventing system damage.
- Prevention: Ensure surge protection devices are installed and functioning to protect the system from electrical surges.
- Check Method: Inspect the surge protection devices regularly and test their functionality using appropriate testing equipment.
Slide 9: Summary and Regular Maintenance Checklist
- Routine Checks: Include these factors in your regular maintenance checklist to ensure the longevity and reliability of your barrier gate system.
- Preventative Maintenance: Address issues promptly to avoid costly breakdowns and ensure continuous operation.
This slide deck outlines the key factors in maintaining a barrier gate system, providing a structured approach to prevent breakdowns. Backing up each point with photographs will further reinforce the importance of these maintenance practices.
