Adding an NVR (No-Volt Release) switch with an emergency stop to a Titan drill press is a beneficial safety upgrade. Here’s a step-by-step guide to help you with the installation:
Benefits of the Modification:
- Improved Safety: The emergency stop button allows for an immediate power cutoff in case of emergencies.
- No-Volt Release Functionality: This prevents the drill press from restarting automatically after a power interruption, reducing the risk of accidental operation.
- Better Accessibility: The new switch can be mounted in a more convenient location, making it easier to operate.
Installation Steps:
1. Select the Appropriate NVR Switch with Emergency Stop
Choose an NVR switch that matches the electrical specifications of your Titan drill press. Ensure it includes both no-volt release and emergency stop features.
2. Fabricate a Mounting Bracket
You may need to create or modify a bracket to securely attach the switch to the drill press. Ensure the bracket is sturdy and can hold the switch in an accessible position.
3. Wiring the Switch
Follow these wiring instructions:
- Disconnect Power: Ensure the drill press is unplugged from the power source.
- Power Input Connections:
- Connect the live (hot) wire from the power source to terminal 2 on the emergency stop button side.
- Connect the neutral wire from the power source to terminal 13 on the switch side.
- Bridge Terminals:
- Bridge terminal 1 on the emergency stop button to terminal 23 on the switch side.
- Motor Connections:
- Connect the motor’s live wire to terminal 24 on the switch side.
- Connect the motor’s neutral wire to terminal 14 on the switch side.
- Grounding: Ensure all grounding connections are secure and meet local electrical codes.
4. Mount the Switch
Secure the switch to the drill press using the fabricated bracket. Make sure the switch is firmly in place and easily accessible.
5. Test the Switch
Perform the following tests to ensure proper functionality:
- Emergency Stop: Press the emergency stop button to verify it cuts off the power immediately.
- No-Volt Release: Simulate a power interruption and ensure the drill press does not restart automatically when power is restored.
Safety and Professional Assistance:
- Safety First: Always follow proper electrical safety protocols when working with electrical components.
- Consult a Professional: If you are not confident in your electrical skills, consider consulting a qualified electrician to perform the installation.
By following these steps, you can enhance the safety and functionality of your Titan drill press with an NVR switch and emergency stop button.
