Knob Installation Guide
Follow these steps to securely attach the knob to the potentiometer (pot) shaft:
- Remove the Plastic Cap:
- Gently pull off the plastic cap from the top of the knob to expose the screw inside.
- Attach the Knob:
- Slide the brass insert (inside the knob) onto the pot shaft.
- Ensure the knob is positioned with a small gap between it and the panel where the pot is mounted. This prevents the knob from touching the panel during rotation.
- Secure the Knob:
- Tighten the screw inside the knob to clamp the brass insert onto the pot shaft. This locks the knob in place.
- Replace the Cap:
- Press the plastic cap back onto the knob to complete installation.
Safety Notes
- Always disconnect power before installing or adjusting the controller.
- Ensure wiring connections (motor and power) are secure using the provided 4mm bullet connectors.
