The Dieffematic BIG motor is a reliable and versatile solution for automating shutters and blinds. Its installation, although simple for those familiar with mechanical work, requires precision and attention to detail. In this article, we will explore the motor assembly steps step-by-step, providing practical advice for achieving the best performance.
1. Preparation for Installation
Before starting the installation, ensure you have the complete BIG motor with accessories, which includes:
- Electromagnetic brake for shutter locking.
- Components for securing to the roller.
- Adapters for the roller and shaft (if necessary).
Required tools:
- Drill with 10mm bits.
- Screwdriver.
- Set of bolt wrenches.
- Level to ensure precise installation.
2. Mounting the Motor on the Roller
- Roller preparation:
- Identify the type of existing shaft and roller. If the rollers are not compatible, use the provided adapter.
- Open the motor "shell" to access the fixing screws.
- Fixing the motor:
- Insert the motor inside the roller, coupling it correctly.
- Use a 10mm drill bit to create a through hole on the roller to secure the main bolt.
- Insert the bolt into the newly created hole to lock the motor in position.
- Secure the second screw, which should not be through, to prevent unwanted motor movements.
- Movement blocking:
- Ensure the motor is firmly anchored to the roller and that there are no free movements or oscillations.
3. Motor Orientation
The BIG motor is designed to offer maximum flexibility in installation:
- It can be mounted in either right or left orientation.
- It can also be installed in reverse mode, with a 180-degree rotation.
Tip: Ensure the electromagnetic brake and mechanical limit switch are easily accessible for subsequent adjustment.
4. Connecting the Electromagnetic Brake and Adjusting the Limit Switch
- Positioning the electromagnetic brake:
- Install the motor so that the brake part is clearly visible and accessible.
- Adjusting the limit switch:
- Ensure that the shutter is completely closed during installation.
- Place the mechanical limit switch near the closure. This will allow you to allocate the entire cursor range to opening, maintaining smooth movement between open and closed positions.
Note: The cursor of the limit switch moves on a worm drive, ensuring precise and stable adjustment over time.
5. Cable Routing
- Holes for threading:
- Identify the side of the tube from which to pass the cables.
- Drill holes in the tube for cable threading, ensuring they are well protected and exit sideways.
- Cable management:
- Connect the cables to the power and control system.
- Ensure there are no bends or damage to the cables during installation.
6. Practical Tips for a Perfect Installation
- Work with the shutter closed: Installing the motor with the shutter closed allows for easier limit switch adjustment and ensures proper system calibration.
- Use of adapters: For non-standard rollers, use the provided adapters to ensure optimal compatibility.
- Lock checking: After securing the motor, ensure it is perfectly locked and that there are no play or unusual movements.
- Final test: Before completing the installation, perform a test to ensure the motor functions correctly in both automatic and manual modes.
