Finding the right parts for your National Arrow Board can be tricky. This comprehensive guide aims to simplify the process, providing you with a detailed parts list and answering frequently asked questions. Whether you're repairing a damaged board or simply looking to upgrade components, this resource will help you navigate the world of National Arrow Board parts.
What are the common parts of a National Arrow Board?
National Arrow Boards, known for their robust construction and reliable performance, utilize a range of components. Common parts include:
- Arrow indicators: These are the most visible components, displaying the direction of traffic flow. They're typically highly visible LEDs or incandescent bulbs, and come in various colors and configurations. Replacing these is often the most common repair.
- Control box: This houses the circuitry that controls the arrow indicators, often including timers, relays, and power supplies. Problems with the control box can affect the entire board's functionality.
- Power supply: This provides the necessary voltage to operate the arrow indicators and control box. A failing power supply can render the entire board inoperable.
- Wiring harness: This connects all the components, from the power supply to the arrow indicators. Damage to the wiring harness can be a difficult problem to diagnose.
- Mounting brackets: These secure the arrow board to its supporting structure, ensuring stability and proper positioning.
- Lenses and housings: These protect the arrow indicators from damage and environmental factors, ensuring optimal visibility. Cracked or yellowed lenses can significantly reduce visibility.
Where can I find a National Arrow Board parts list?
Unfortunately, a single, universally available parts list for all National Arrow Board models is not readily accessible online. National's product line encompasses a wide variety of boards with varying specifications. The best approach is to:
- Identify your specific model number: This number is usually located on a label affixed to the board itself or in the accompanying documentation.
- Contact National directly: Reaching out to National's customer support or sales department with your model number will provide the most accurate and up-to-date parts list for your specific board.
- Check online retailers: Some online retailers specializing in traffic control equipment might have parts lists or catalogs available, but always verify compatibility with your model number.
What if I need to replace the arrow indicators?
Replacing arrow indicators usually involves unscrewing the old indicator and inserting the new one. However, the specific procedure varies slightly depending on the model. Consult your board's instruction manual or contact National for guidance if you're unsure. Ensure you purchase indicators with the correct voltage and wattage to avoid damaging the control box.
How can I troubleshoot a malfunctioning National Arrow Board?
Troubleshooting a malfunctioning board requires a systematic approach. Start by checking the power supply, then examine the wiring harness for any loose connections or damaged wires. If the problem persists, the control box or arrow indicators themselves may be faulty. Again, contacting National support can provide valuable troubleshooting assistance.
What are some common problems with National Arrow Boards?
Common problems include:
- Burnt-out arrow indicators: These are easily replaced, and preventative maintenance, such as regular cleaning, can extend their lifespan.
- Faulty wiring: Damaged or corroded wiring can cause intermittent or complete failure of the board.
- Control box malfunctions: These are more complex to repair and may require professional assistance.
- Power supply issues: A failing power supply will prevent the board from functioning entirely.
This guide provides a starting point for understanding National Arrow Board components and troubleshooting common issues. Remember that always contacting National directly with your specific model number is the most reliable way to obtain accurate parts information and support. Regular maintenance can significantly extend the life of your arrow board and prevent costly repairs.
