Installationsvejledning
Professional installation is recommended. Ensure the power is disconnected before beginning installation. This controller is designed for DC brushed motors only.
Ledningsforbindelser
- Connect the two thicker wires from the controller (blue and yellow) to the motor. The blue wire connects to the motor's red wire, and the yellow wire connects to the motor's black wire.
- Connect the two thicker wires from the controller (red and black) to the battery. The red wire connects to the positive (+) terminal of the battery, and the black wire connects to the negative (-) terminal.
- Connect the throttle connector. The throttle typically has three wires; ensure the red wire connects to red and the black wire connects to black.
- Connect the ignition switch.
- After all connections are secure, turn on the ignition switch. The motor should now be ready for operation.
Important Note: Carefully verify all wire connections. Incorrect wiring, especially for the power cord, can cause damage to the controller.

Operation
Once installed and powered, the controller provides steady and sensitive control of speed. Use the connected throttle (speed governor 1-4V) to regulate motor speed.
Opretholdelse
The controller's rugged aluminum housing with integrated cooling fins helps dissipate heat. Rubber grommets protect sensitive electronics from environmental elements. Regularly inspect all connections for tightness and signs of wear. Keep the controller clean and free from excessive dust or moisture.
Fejlfinding
- If the motor does not run after installation, first check all power and signal connections for correct polarity and secure fit.
- Ensure the battery is adequately charged and providing the correct voltage (36V).
- Verify the ignition switch is in the "ON" position.
- If issues persist, consult a professional for diagnosis. Avoid attempting repairs if you are not qualified, as this may void any warranty and cause further damage.
