How to Use Super Duty Actuators: Examples, Pinouts, and Specs

Super Duty Actuators, manufactured by Firgelli Automations (Part ID: F-SD-H-220-12v-XX), are robust devices designed to convert electrical energy into mechanical motion. These actuators are specifically engineered for heavy-duty applications requiring high torque, precision, and reliability. Their durable construction and high-performance capabilities make them ideal for use in industrial automation, robotics, agricultural machinery, and other demanding environments.

• Industrial automation systems
• Robotic arms and manipulators
• Agricultural equipment
• Heavy machinery and construction tools
• Adjustable platforms and lifting mechanisms

Below are the key technical details for the Super Duty Actuators:

The actuator typically comes with a 2-wire configuration for power and control. The pinout is as follows:

1. Power Supply: Ensure the actuator is powered by a 12V DC power source capable of supplying sufficient current for the load.
2. Polarity Control: The actuator's direction of motion is controlled by reversing the polarity of the power supply:
   • Positive voltage on the red wire and negative on the black wire will extend the actuator.
   • Reversing the polarity will retract the actuator.
3. Mounting: Securely mount the actuator using the provided brackets or custom mounting solutions. Ensure the actuator is aligned with the load to prevent binding or damage.
4. Control Options:
   • Use a DPDT (Double Pole Double Throw) switch for manual control.
   • For automated control, integrate the actuator with a microcontroller (e.g., Arduino UNO) and an H-bridge motor driver.

Below is an example of how to control the Super Duty Actuator using an Arduino UNO and an L298N H-bridge motor driver:

// Arduino UNO code to control the Super Duty Actuator
// Ensure the actuator is connected to the L298N motor driver
// IN1 and IN2 control the actuator's direction

const int IN1 = 7; // L298N IN1 pin connected to Arduino pin 7
const int IN2 = 8; // L298N IN2 pin connected to Arduino pin 8

void setup() {
  pinMode(IN1, OUTPUT); // Set IN1 as output
  pinMode(IN2, OUTPUT); // Set IN2 as output
}

void loop() {
  // Extend the actuator
  digitalWrite(IN1, HIGH); // Set IN1 high
  digitalWrite(IN2, LOW);  // Set IN2 low
  delay(5000);             // Extend for 5 seconds

  // Stop the actuator
  digitalWrite(IN1, LOW);  // Set IN1 low
  digitalWrite(IN2, LOW);  // Set IN2 low
  delay(2000);             // Pause for 2 seconds

  // Retract the actuator
  digitalWrite(IN1, LOW);  // Set IN1 low
  digitalWrite(IN2, HIGH); // Set IN2 high
  delay(5000);             // Retract for 5 seconds

  // Stop the actuator
  digitalWrite(IN1, LOW);  // Set IN1 low
  digitalWrite(IN2, LOW);  // Set IN2 low
  delay(2000);             // Pause for 2 seconds
}

• Current Rating: Ensure the power supply and motor driver can handle the actuator's current requirements under load.
• Duty Cycle: Operate the actuator within its 25% duty cycle to prevent overheating and damage.
• Alignment: Misalignment during installation can cause excessive wear or failure.
• Environmental Conditions: The IP66 rating ensures protection against dust and water, but avoid submerging the actuator.

1. Actuator Does Not Move:

   • Cause: Insufficient power supply or incorrect wiring.
   • Solution: Verify the power supply voltage and current. Check the wiring for proper connections.

2. Actuator Moves in One Direction Only:

   • Cause: Faulty polarity control or damaged motor driver.
   • Solution: Test the motor driver and ensure proper polarity switching.

3. Overheating:

   • Cause: Exceeding the duty cycle or operating under excessive load.
   • Solution: Reduce the load or operating time. Allow the actuator to cool down.

4. Unusual Noise or Vibration:

   • Cause: Misalignment or mechanical obstruction.
   • Solution: Inspect the mounting and ensure the actuator is aligned with the load.

• Can the actuator be used outdoors? Yes, the IP66 rating ensures it is suitable for outdoor use, but avoid prolonged submersion.

• What is the maximum stroke length available? The stroke length is customizable. Contact Firgelli Automations for specific options.

• Can I control the actuator with a PWM signal? Yes, you can use a PWM signal with a motor driver to control the speed and position of the actuator.

• What happens if I exceed the duty cycle? Exceeding the duty cycle may cause the actuator to overheat and reduce its lifespan. Always adhere to the specified duty cycle.
