3.1 Contenu du paquet
Vérifiez que tous les composants sont présents avant de commencer l'installation :
- Somfy LT50 506S2 Tubular Motor
- Câble d'alimentation (attaché)
- Mounting Brackets (may be supplied separately with the application)
- Crown and Drive Wheel (may be supplied separately with the application)
3.2 Motor Overview

Figure 1 : Fin view of the Somfy LT50 506S2 motor, highlighting the round drive head where the crown and drive wheel attach.
The image above shows the drive head of the Somfy LT50 506S2 motor. This is where the crown and drive wheel are fitted to engage with the tube of your application (e.g., roller blind). The central opening is for the limit setting tool.
3.3 Montage du moteur
- Attach the crown and drive wheel to the motor head. Ensure they are seated correctly.
- Insert the motor into the tube of your application. The drive wheel should fit snugly inside the tube.
- Mount the assembly into the chosen location using appropriate brackets. Ensure the motor is level and securely supported.
- Verify that the tube rotates freely without obstruction.
3.4 Câblage électrique
The Somfy LT50 506S2 operates on 120V AC. Wiring must be performed by a qualified professional.
- Connect the motor's power cable to a suitable 120V AC power supply, typically through a wall switch or control system.
- Assurez une bonne mise à la terre.
- Refer to the wiring diagram provided with your specific control system or switch for exact connections (Live Up, Live Down, Neutral, Ground).
3.5 Fixer les limites
Limit settings define the upper and lower stopping points of your application. This motor uses mechanical limit switches, typically adjusted with a specialized tool (often a small hex key or screwdriver) inserted into the holes on the motor head.
- Mise sous tension : Appliquer la puissance au moteur.
- Identifier les vis de réglage : Locate the two adjustment screws on the motor head. One controls the upper limit, the other the lower limit. Consult your application's specific instructions to identify which screw corresponds to which limit.
- Définir la limite supérieure :
- Run the application upwards until it reaches the desired upper stopping point.
- Insert the adjustment tool into the corresponding screw and turn it slowly. Turning in one direction will extend the travel, the other will retract it. Adjust until the motor stops precisely at the desired upper position.
- Définir la limite inférieure :
- Run the application downwards until it reaches the desired lower stopping point.
- Insert the adjustment tool into the corresponding screw and adjust until the motor stops precisely at the desired lower position.
- Test Limits: Cycle the application up and down several times to ensure the limits are set correctly and consistently.
4. Mode d'emploi
The Somfy LT50 506S2 motor is typically controlled by a wall switch or a remote control system (sold separately).
4.1 Basic Operation (Wall Switch)
- Bouton HAUT : Press and hold to move the application upwards. Release to stop. If limits are set, a quick press may send it to the upper limit.
- Bouton BAS : Press and hold to move the application downwards. Release to stop. If limits are set, a quick press may send it to the lower limit.
- STOP Button (if available): Press to immediately stop the application at its current position.
4.2 Fonctionnement de la télécommande (le cas échéant)
If using a Somfy remote control, refer to the remote's specific instructions for pairing and operation. Generally, the remote will have dedicated buttons for Up, Down, and Stop functions, similar to a wall switch.
