4. End Position Adjustment: Once powered, use the control unit to set the upper and lower end positions. The electronic adjustment system simplifies this process via the connected cable. Follow the specific instructions in the detailed product manual for precise adjustment steps.
5. Testing: After adjustment, thoroughly test the motor's operation, including obstacle detection and overload protection, to ensure proper functionality.

4. Operating Instructions

The Selve SEL-PLUS 2/7 motor operates roller shutters by receiving commands from a connected switch or control system. Once installed and end positions are set:

• Up Command: Activates the motor to raise the roller shutter to its programmed upper end position.
• Down Command: Activates the motor to lower the roller shutter to its programmed lower end position.
• Stop Command: Interrupts the motor's movement, stopping the roller shutter at its current position.
• Automatic Functions: The motor's electronic system automatically manages end positions and reacts to obstacles or overloads as programmed during setup.

5. Maintenance

The Selve SEL-PLUS 2/7 tubular motor is designed for long-term, maintenance-free operation. However, periodic checks can help ensure its longevity:

• Cleaning: Keep the roller shutter and surrounding area clean from dust and debris that could impede movement. Do not clean the motor directly with liquids.
• Connection Check: Periodically inspect the electrical connections for any signs of wear or loosening. Ensure the cable is not pinched or damaged.
• No User Serviceable Parts: The motor unit itself contains no user-serviceable parts. Do not attempt to open or repair the motor.
• Professional Inspection: If you notice any unusual noises, erratic operation, or significant changes in performance, contact a qualified technician for inspection.

6. Troubleshooting

If you encounter issues with your Selve SEL-PLUS 2/7 tubular motor, consider the following common troubleshooting steps:

• Motor Not Responding:
  • Check the power supply to the motor. Ensure the circuit breaker is not tripped.
  • Verify all electrical connections are secure and correctly wired.
  • Test the control switch or system to ensure it is functioning correctly.
• Incorrect End Positions:
  • The end positions may need to be re-adjusted. Refer to the detailed adjustment procedure in the full product manual.
• Shutter Stops Unexpectedly:
  • This could indicate obstacle detection or overload protection activation. Check for any obstructions in the shutter's path or excessive resistance.
  • If the issue persists without visible cause, contact technical support.
• Unusual Noises:
  • Loud grinding or clicking noises may indicate a mechanical issue within the roller shutter system or the motor. Discontinue use and seek professional assistance.

For complex issues or if troubleshooting steps do not resolve the problem, contact Selve customer support or a certified technician.
