4. Informació de seguretat
Please read and understand all safety instructions before installing or operating the linear actuator. Failure to follow these instructions may result in electric shock, fire, serious injury, or property damage.
- Seguretat elèctrica: Assegureu-vos que la font d'alimentació coincideixi amb el volum de l'actuadortage (DC 12V). Disconnect power before any installation, maintenance, or troubleshooting. Avoid exposing electrical connections to moisture.
- Seguretat mecànica: Keep hands, clothing, and other objects clear of moving parts during operation. Do not exceed the maximum load capacity of 900N (225lbs). Ensure the actuator is securely mounted to prevent accidental detachment.
- Ambiental: The actuator is IP54 rated, meaning it is protected against dust ingress and splashing water. However, it is not designed for submersion. Avoid operating in extreme temperatures outside the specified range (-20°C to +65°C).
- Nens i animals de companyia: Keep children and pets away from the actuator during operation to prevent injury.
5. Configuració i instal·lació
Proper installation is crucial for the safe and efficient operation of your linear actuator. Follow these general guidelines:
- Muntatge: Use the provided mounting brackets to securely attach the actuator to a stable surface. Ensure the mounting points can withstand the maximum force exerted by the actuator. The actuator can be mounted in any orientation.
- Alineació: Ensure the actuator is properly aligned with the load it will be moving. Misalignment can cause excessive wear, reduced performance, and potential damage.
- Connexió elèctrica: Connect the actuator to a DC 12V power source. The actuator typically has two wires; reversing the polarity will reverse the direction of motion. Consider using a control switch or relay for easy operation and safety.
- Interruptors de límit: The actuator has built-in, non-adjustable limit switches that automatically stop the rod at its fully retracted and fully extended positions. Do not attempt to bypass or modify these switches.

6. Instruccions de funcionament
Operating the linear actuator is straightforward:
- Encès: Connect the actuator to a stable DC 12V power supply.
- Estendre/Retreure: Apply DC 12V power to the actuator. The direction of the rod's movement (extend or retract) depends on the polarity of the voltage applied to the two wires.
- Parada: The actuator will automatically stop when it reaches its fully extended or fully retracted position due to the internal limit switches. To stop the actuator at an intermediate position, simply cut the power supply.
- Reversing Direction: To reverse the direction of motion, reverse the polarity of the DC 12V power supply. This can be achieved using a DPDT (Double Pole Double Throw) switch or a motor control circuit.

7. Manteniment
The Homend DC12V Linear Actuator is designed for minimal maintenance. However, periodic checks can help ensure its longevity and optimal performance:
- Neteja: Keep the actuator rod and housing clean from dust, dirt, and debris. Use a soft, dry cloth. Avoid using harsh chemicals or solvents.
- Lubricació: The internal components are pre-lubricated for life. Do not attempt to lubricate the internal mechanism.
- Inspecció: Regularly inspect the mounting points, wiring, and the actuator rod for any signs of wear, damage, or corrosion. Tighten any loose fasteners.
- Protecció del medi ambient: While IP54 rated, avoid prolonged exposure to direct heavy rain or harsh environmental conditions if possible, to maximize lifespan.
8. Solució De Problemes
Si teniu problemes amb el vostre actuador lineal, consulteu els següents problemes i solucions habituals:
| Problema | Causa possible | Solució |
|---|---|---|
| L'actuador no es mou | No power, incorrect voltage, loose wiring, overloaded, internal damage. | Check power supply (DC 12V), ensure secure connections, reduce load, inspect for damage. |
