The BIG motor by Dieffematic is a reliable, versatile solution for automating roller shutters. Although installation is straightforward for anyone familiar with mechanical work, it requires precision and attention to detail. In this article, we will guide you through the motor installation process step by step, with practical tips to help you get the best performance.
1. Preparing for Installation
Before starting the installation, make sure you have the BIG motor and all its accessories, including:
- Electric brake for locking the roller shutter.
- Components for securing the motor to the roller.
- Adapters for the roller and shaft (if required).
Tools required:
- Drill with 10 mm bits.
- Screwdriver.
- Set of spanners for bolts.
- Spirit level for precise installation.
2. Mounting the Motor on the Roller
-
Preparing the roller:
- Identify the type of existing shaft and roller. If the roller is not compatible, use the supplied adapter.
- Open the motor’s “housing” to access the fixing screws.
-
Securing the motor:
- Insert the motor into the roller, ensuring they are correctly aligned.
- Use a 10 mm drill bit to drill a through-hole in the roller for the main bolt.
- Insert the bolt into the hole you have just drilled to secure the motor in position.
- Fit the second screw, which must not go all the way through, to prevent unwanted motor movement.
-
Preventing movement:
- Check that the motor is securely anchored to the roller and that there is no free play or wobble.
3. Motor Orientation
The BIG motor is designed to offer maximum flexibility during installation:
- It can be mounted on the right or left.
- It can also be installed in reverse, rotated by 180 degrees.
Tip: Make sure the electric brake and mechanical limit switch are easily accessible for subsequent adjustment.
4. Connecting the Electric Brake and Adjusting the Limit Switch
-
Positioning the electric brake:
- Install the motor so that the electric brake is clearly visible and accessible.
-
Adjusting the limit switch:
- Make sure the roller shutter is fully closed during installation.
- Position the mechanical limit switch close to the closed position. This allows you to use the full slider travel for opening, ensuring smooth movement between the open and closed positions.
Note: The limit switch slider moves along a lead screw, ensuring precise adjustment that remains stable over time.
5. Cable Routing
-
Drilling cable entry holes:
- Identify which side of the tube the cables will pass through.
- Drill holes in the tube for the cables, making sure they are well protected and exit from the side.
-
Cable management:
- Connect the cables to the power supply and control system.
- Make sure the cables are not bent or damaged during installation.
6. Practical Tips for Perfect Installation
- Work with the shutter closed: Installing the motor with the shutter closed makes it easier to adjust the limit switch and ensures the system is correctly calibrated.
- Using adapters: If the rollers are non-standard, use the supplied adapters to ensure optimal compatibility.
- Check the motor is secure: After securing the motor, make sure it is firmly in place and there is no play or unusual movement.
- Final test: Before completing the installation, test the motor to verify that it works correctly in both automatic and manual modes.
