4.2. Rail Assembly
Assemble the rail sections according to the diagrams provided in the detailed installation guide (not included in this general manual, refer to the manufacturer's full guide for specific steps). Ensure all connections are secure. The rail is supplied with a travel length suitable for doors up to 2.6 meters high. Track extensions are available as accessories if needed.

4.4. Electrical Connection
The system features easy electrical installation. No special ceiling outlet is required; it can be used with an existing standard outlet. Connect the motor unit to the control unit and then to a power source. Ensure all wiring is secure and protected. The control unit includes an integral radio receiver (FM 868.8 MHz) and 112 memory slots for transmitters.
4.5. Safety Feature Setup (DPS)
The Dynamic Power System (DPS) electronically measures the required force and adjusts to changing external conditions, ensuring high safety. During initial setup, the system will learn the door's travel limits and required force. Obstacle detection ensures the door reverses when meeting an obstacle. Test this feature as described in Section 2.
The system also features a controlled soft start and soft stop for smooth operation and reduced wear, contributing to its energy-efficient design.
5. Operating Instructions
5.1. Using the Handheld Transmitter (Remote Control)
The included Handheld Transmitter 4020 allows you to operate your garage door wirelessly. Press the designated button on the transmitter to open or close the garage door. Pressing it again during motion will stop the door. A third press will reverse the door's direction.
To program additional transmitters, refer to the detailed programming instructions in the full manufacturer's manual.
5.2. Using the Interior Push-Button
The separate control unit features an integrated push-button. Press this button to open or close the garage door from inside your garage. The integrated lighting will illuminate the garage when the door is operated.
5.3. Manual Release
In case of a power outage or malfunction, you can manually operate the garage door. Locate the manual release handle (usually a red cord) attached to the trolley on the rail. Pull the handle firmly to disengage the motor from the door. You can then open or close the door by hand. To re-engage, push the handle back into position or operate the opener once the power is restored.
6. Maintenance
Regular maintenance ensures the longevity and safe operation of your garage door motorization system.
- Monthly: Test the safety reverse system (refer to Section 2). Inspect the garage door for proper balance and smooth operation. Lubricate rollers, hinges, and bearings as recommended by your garage door manufacturer.
- Annually: Have a qualified technician inspect the entire garage door system, including springs, cables, and the opener.
- Keep the motor unit and control unit clean and free from dust and debris.
- Check the photocell sensors (if installed) for alignment and cleanliness.
Do not attempt to repair the motor unit or control unit yourself. Contact qualified service personnel for any repairs.
