3. Setup
3.1 Unpacking and Inspection
Carefully remove the linear actuator and its accessories from the packaging. Inspect for any visible damage. The package typically includes the linear actuator and two mounting brackets.
3.2 Mounting
Secure the linear actuator using the provided mounting brackets. Ensure the mounting points are stable and can support the actuator's weight and maximum load capacity. The brackets allow for pivot movement.
3.3 Wiring
Connect the actuator to a 12V DC power source. The actuator has two wires (typically red and black). Reversing the polarity of the DC input voltage will reverse the direction of the actuator's movement (extension or retraction).
3.4 Stroke Length Calculation
The actuator has built-in limit switches that automatically stop the movement at its fully extended and fully retracted positions. The minimum length (Lmin) and maximum length (Lmax) are calculated as follows:
- Lmin (Fully Closed Length): Lmin = 54.5mm + Stroke Length
- Lmax (Fully Open Length): Lmax = Lmin + Stroke Length = 54.5mm + (2 × Stroke Length)
Examples:
- For 30mm Stroke:
Lmin = 54.5mm + 30mm = 84.5mm
Lmax = 84.5mm + 30mm = 114.5mm - For 50mm Stroke:
Lmin = 54.5mm + 50mm = 104.5mm
Lmax = 104.5mm + 50mm = 154.5mm
Ensure your application's required travel falls within these limits.
4. Operating Instructions
To operate the linear actuator:
- Ensure the actuator is securely mounted and correctly wired to a 12V DC power source.
- Apply 12V DC power to the actuator. The rod will begin to extend or retract depending on the polarity.
- To reverse the direction of movement, reverse the polarity of the 12V DC power supply.
- The actuator will automatically stop when it reaches its fully extended or fully retracted position due to the internal limit switches.
- Do not attempt to force the actuator beyond its mechanical limits or after the limit switches have engaged, as this can cause damage.
5. Maintenance
The linear actuator is designed for low maintenance. Follow these guidelines to ensure longevity:
- Keep the actuator clean and free from dust, dirt, and debris.
- Periodically check all electrical connections to ensure they are secure and free from corrosion.
- Inspect mounting points for any signs of wear or loosening.
- Avoid exposing the actuator to extreme moisture or corrosive environments beyond its IP54 rating.
- Do not lubricate the internal mechanism unless specifically instructed by the manufacturer, as this can interfere with the built-in lubrication.
6. Troubleshooting
If you encounter issues with your linear actuator, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Actuator does not move | No power, incorrect wiring, overloaded, internal damage. | Check power supply (12V DC). Verify wiring polarity. Reduce load if exceeding max capacity. Contact support if internal damage is suspected. |
| Actuator moves in wrong direction | Incorrect power polarity. | Reverse the polarity of the 12V DC power supply. |
| Actuator stops prematurely | Obstruction, excessive load, faulty limit switch. | Check for obstructions. Ensure load is within limits. If problem persists, contact support. |
| Unusual noise during operation | Mechanical wear, foreign object, excessive load. | Inspect for foreign objects. Reduce load. If noise continues, contact support. |
7. User Tips
While no specific user tips from reviews or Q&A were provided, general best practices for linear actuators include:
- Always ensure your power supply matches the actuator's voltage (12V DC).
- Avoid continuous operation at maximum load for extended periods to prevent overheating and premature wear.
- Consider using a control circuit with a DPDT (Double Pole Double Throw) switch for easy polarity reversal and direction control.
- For outdoor or harsh environments, ensure additional protection beyond the IP54 rating if necessary.
8. Warranty and Support
For any technical assistance, warranty claims, or further inquiries, please contact the seller or manufacturer directly. Keep your purchase records handy when seeking support.
