4. Instruccions de funcionament

4.1 Speed Control Modes

The controller supports three methods for speed adjustment:

• On-board Knob Adjustment: Rotate the potentiometer knob on the controller for 0-100% smooth speed adjustment.
• 0.2-4.8V Analog Signal Control: Connect an external analog signal source for speed control.
• 1-4.2V Hall Handle Control: Use a Hall effect throttle handle for speed regulation.

4.2 Adjustable Overload Protection

The controller features adjustable overcurrent and delay protection to prevent damage from motor stalls or sudden current spikes.

• Current Levels: 6 levels from 5A to 30A (default 20A).
• Configuració del retard: Optional delay settings to prevent false triggers.

When an overload is detected, the output will be cut off, and the LED indicator will flash.

4.3 Setting Current Levels and LED Indicators

The controller uses LED indicators for status checking and button settings for current levels.

• To Enter Current Setting Mode: Press and hold the K2 button. The LED will start blinking.
• To Cycle Through Current Levels: Press K2 repeatedly to cycle through the 6 current levels (5A, 10A, 15A, 20A, 25A, 30A).
• To Confirm Setting: The LED will become solid when a level is selected and confirmed.
• Estat LED:
  • LED OFF / Solid Green: Normal Operation
  • LED Blinking Red: Overload Protection Triggered
  • LED Fast Flashing: Current Level Setting Mode Active

All custom settings are saved after power off, eliminating the need to reset them for daily use.

5. Manteniment

To ensure optimal performance and longevity of your RioRand PWM DC Motor Speed Controller, follow these maintenance guidelines:

• Mantenir net: Regularly clean the controller's exterior with a dry, soft cloth. Avoid using liquids or abrasive cleaners.
• Ventilació: Ensure the ventilation holes on the casing are not obstructed to allow for proper heat dissipation.
• Comprovacions de connexió: Periodically inspect all wiring connections for tightness and signs of wear or corrosion. Re-tighten if necessary.
• Condicions ambientals: Operate and store the controller in a dry environment, away from excessive dust, moisture, and extreme temperatures.
• Eviteu danys físics: Protect the unit from impacts or drops that could damage internal components.

6. Solució De Problemes

If you encounter issues with your speed controller, refer to the following common problems and solutions:

• El motor no respon:
  • Check power input: Ensure DC power (8-50V) is correctly connected and active.
  • Verify motor connections: Confirm motor wires are securely connected to M+ and M-.
  • Check compatibility: Ensure you are using a brushed DC motor. This controller does not work with brushless motors or AC power.
  • Inspect for damage: Look for any visible signs of damage to the controller or wiring.
• LED Blinking Red (Overload Protection):
  • This indicates an overcurrent event (e.g., motor stall, excessive load).
  • Reduce the load on the motor or check for obstructions.
  • Considera incrementasing the overcurrent protection level (refer to Section 4.3) if your motor's normal operating current is higher than the current setting, but do not exceed 30A.
  • Allow the unit to cool down if it feels hot.
• Control de velocitat inconsistent:
  • Ensure the control knob or external signal source is functioning correctly.
  • Check for loose connections in the control signal wiring.
• Sobreescalfament de la unitat:
  • Ensure adequate ventilation around the controller.
  • Verify that the motor's power requirements do not exceed the controller's maximum limits (Max 30A).
  • Redueix la càrrega del motor.

If problems persist after attempting these troubleshooting steps, contact customer support.
