Connecting electric roller shutters

What is the connection diagram for a roller shutter for a window?

It is not known what type of roller shutters was chosen and in what quantity. To connect electric roller shutters to a power source, use only double-insulated wires, preferably 4-core and with a cross-sectional area of at least 0.75 sq. mm. Be sure to use junction boxes to connect wires. Take into account the total power of electric drives when installing a large number of protective roller shutters. From the control unit to the general 220V power supply, use wires with a cross-section of 1.5-2 sq.mm, and the cable connecting all units should have a cross-section of 2.5 sq.mm. Automatic roller shutters are divided into groups and connected to the network using a separate cable from the general power supply panel. This is important to take into account, if power comes to one drive from another, then when turned on, a large total power may appear on the roller shutters, and on the rest the voltage will drop. Then instability in the operation of electric drives is guaranteed.

For each direction of a separate electric drive, one contact must be provided.

If you carefully read the roller shutter connection diagrams, you can handle this work yourself; if you have any doubts, it is better to contact specialists. Their services may not be cheap, but they will be done professionally and with a guarantee.

This diagram shows how to connect roller shutters through group control units to one switch.

For correct connection, it is necessary to provide one contact for each direction of each electric drive.

Here is a typical diagram for connecting an electrical wire to the electrical network, where

Common Installation Tips

Installation and configuration must be carried out in accordance with the connection diagram for electric roller shutters. The following recommendations must be followed:

Wires must be taken with a cross-section of at least 0.75-2.5 mm2, with 4 cores and double insulation.
The use of wires with polyethylene insulation is prohibited.
To connect cables, use distribution boxes and terminal connectors.
If there are more than one shutter, the wiring must take this into account. The connecting cable must be able to withstand the required power.
The electric drive needs to provide one contact for each direction of movement.

Remove the cover from the protective box.
We disconnect the mechanism for fastening the blade to the shaft (crossbar locking or spring-traction mechanisms.).
Remove the octagonal shaft.
If the seats for the new engine are not adapted, then we prepare the shaft and side covers for the installation of a new intrashaft engine.

1. Install the adapter and the end position ring on the electric drive. 2. We screw the mounting plate to the electric motor, which is necessary for attaching the shaft to the side covers. 3. Drill mounting holes for the mounting plate of the roller shutter motor. 2. We fasten the electric motor to the cover installed on the drive side with screws and nuts, having previously drilled the required number of holes in the cover and countersinked the head of the screws from the outside of the side cover. Install the bearing into the capsule.

Install the electric motor assembly with the cover into the shaft.
Pull the bearing capsule out of the shaft all the way into the cover and secure it with a rivet, having previously jointly drilled a hole for the rivet in the shaft and capsule.

blue - neutral
brown – rotation direction phase first (one way)
black – rotation direction phase two (in the other direction)
yellow-green – grounding

The switch must have a condition, mechanical or electrical phase blocking from simultaneous activation of opposite directions of rotation of the drive shaft.

If you look at the diagram in other words, terminals 2 and 3 should not intersect, since using a switch without a mechanical or electrical interlock will lead to a short circuit. The short circuit current is quite high, which causes failure of the roller shutter drive. You have installed the engine in the octagonal shaft, secured the blade and the last step remains to configure the engine. It is necessary to set the extreme adjustment positions (stopping positions of the roller shutter blade at the lower and upper points). The extreme limit positions are adjusted by adjusting the limit switch system. Sometimes these adjustments can go wrong due to voltage surges. In order not to repair the roller shutter, watch the adjustment of the end positions. Order engine tuning. Diagnostics of roller shutter motor operation. Roller shutter motor repair.

Setting the upper end position:

Turn on the drive to lift the blade, holding the key up and turning the corresponding adjusting screw in the direction “ “, move the blade to the desired upper position. As a result, the drive automatically turns off when the web reaches the required upper position.

Setting the lower end position:

Turn on the drive to lower the blade by holding the down key and at the same time turning the corresponding adjusting screw in the direction ““ move the blade to the desired upper position. As a result, the drive automatically turns off when the web reaches the required lower position.

Options for connecting power supply to electric curtain motors

There are several methods for connecting power:

Wireless automation : powered by batteries or a small solar panel. Recommended in case of renovation or for roller blinds, horizontal and fabric blinds.
Standard motorization: powered by electrical network. Recommended for new installations of curtains, large blinds and home theater screens.

Mains power supply

In this case, it is necessary to install electrical wiring during the construction/repair phase. The number of wires depends on the method of controlling the curtains:

when controlling curtains from a push-button switch, you need to lay a 4-core cable with a wire cross-section of 1 mm 2 or 1.5 mm 2 to the intended installation location of the electric drive. I will explain this point further in the electrical diagram.
when controlling curtains from a remote control, you need to lay a 3-core cable with a wire cross-section of 1 mm 2 or 1.5 mm 2.

Powered by solar panel

Yes, this is possible. Completely dispense with additional electrical wiring. In this case, the diagram will look like this:

Power supply technology:

Battery powered

The drive with a supply voltage of 12 volts and low power consumption (patented by Somfy) can be operated either from a solar panel or from batteries. In standby mode, the drive's power consumption is zero. The service life of the drive is more than 10 years.

How to install, connect and configure the electric drive?

Practice shows that most buyers who choose a mechanical drive to control their roller shutters eventually end up improving the device by installing an electric motor in it. This is not surprising, because an automatic drive means comfort, ease of control and additional opportunities for owners. With it you can control roller shutters from a distance, which is especially important in rain and cold. Garage doors that are operated using an electric drive provide maximum comfort to the motorist and save time that you could spend getting out of the car, opening the gate yourself, going back to the car and finally parking.

So, have you decided to install an electric drive on your roller shutters? This is the right decision, and in this case you can call the experts who will carry out the installation, or you can do everything yourself. What is more reliable and what is cheaper is clear without words.

If you decide to install an electric drive on your roller shutters yourself, you will need this information.

How do electric roller shutters work?

To begin with, let us recall the main components of automatic roller shutters and their interaction.

Connecting roller shutters with an electric motor

After you have finished installing the electric drive into the roller shutter body, it is time to connect it to the electrical network.

Four-wire electrical cables are used to connect the automatic drive. Each of the wires has its own purpose, determined by color coding, namely:

Blue – neutral
Brown – rotation direction phase in one direction
Black – phase of rotation direction in the other direction
Yellow-green - grounding

Diagram for connecting the electric roller shutter drive to the electrical network. As a switch that controls the operation of the electric roller shutter motor, only a device with phase blocking from simultaneous activation of two opposite directions of shaft movement can be used. Both mechanical and automatic phase blocking can be used

Setting up the electric drive

The moment has come that is very important to ensure the correct operation of roller shutters and extend their service life.

Setting up the electric drive involves setting the end positions at which the blade should stop at the top and bottom points. The end positions are set by adjusting the limit switches.

Even if you don’t change the electric drive in the future, you need to regularly inspect the crossbars and debug the roller shutter limit switches, as they can go astray due to power surges

How to adjust limit switches?

Lower the roller shutter, then locate the adjusting screw on the drive head. The designations “+” and “-” mean an increase and decrease in the stroke of the roller shutter blade, respectively.

In order to set the upper end position of the blade, turn on the lifting drive and, while holding the “up” button, use the adjusting screw to bring the blade to the desired upper position.

The lower end position is set in the same way as described above.

If all procedures were carried out without errors, in the future the automatic drive will raise and lower the blade to the specified positions, turning off at them.

Automatic roller shutters are very convenient

That’s probably all you need to know about installing and configuring an electric drive for roller shutters. It’s up to you to do it yourself or seek help from specialists.

The advantages of this choice include the following points:

Burglary protection. To open the aluminum sheet, you need to use cutting tools, and this will create a lot of noise.
Soundproofing. When the roller blinds are closed, the noise level in the room is reduced by up to 30%.
Possibility of adjusting the degree of illumination. Roller shutters partially open and close, and the direction of their slats is also adjustable.
Thermal insulation. The canvases may have insulation inside to reduce heat loss.
Aesthetics. Wide selection of colors and imitation textures.
Protection from prying eyes, atmospheric phenomena and glass damage.
Easy to use. The products are easy to clean, do not require special care, and last a long time.
Fire safety. Unlike metal bars, security shutters can be easily and quickly opened from the inside, allowing people to escape in an emergency.

Aluminum roller shutters

Modern steel roller shutters are a promising product that is in demand in ordinary homes, offices and secured facilities.

Steel roller shutters

You can close and secure any glass spaces, any window shapes, openings, gates and storage sections.

Roller shutters for windows

To protect your cottage, house and apartment, we recommend installing roller shutters on your windows - a reliable profile and a wide selection of colors.

Automatic roller shutters

The design of roller shutters uses a special mechanism that makes the system easy to operate.

7 steps to choosing roller shutters view

Remote control control

Controlling a window mechanism using a remote control is one of the simplest. Connecting such a movement scheme is very simple.

Connecting the remote control

To assemble the automatic blind control mechanism, you need to have the following:

drive unit;
infrared sensor;
remote;
control unit (controller).

Build process

Pay attention to the choice of drive. The greater its power, the better the system will work.

The drive is mounted in the cornice or at the location where the blinds are installed. A main controller is installed locally, which, using a motion sensor or timer, will transmit commands to the electric drive itself . The infrared sensor itself and the switch are mounted no more than 30 meters away.

You can use a slightly different, simpler scheme.

Simplified remote control connection diagram

In this case, you only need to install the electric drive itself and the radio receiver. The drive is also mounted in the cornice. A radio receiver is installed locally and connected to the network via a power supply . With this assembly mechanism you will need:

drive unit;
radio;
power unit;
remote control.

What else attracts consumers with automatic roller shutters:

The user does not need to know the operating principle of the roller shutter lifting mechanism and the procedure for its maintenance. Even a child can press the corresponding button on the switch or control panel.
There is no need for physical effort to operate the roller shutters. This is an important advantage of the electric drive, given that modern roller shutters for garages and other large openings can weigh more than 500 kg.
Possibility to combine electric drives of all roller shutters with a common network. It is very convenient to manage the entire protective complex from one place.
The use of a radio remote control allows you to control from a distance, and the use of a smartphone allows you to control it in the absence of owners on site.
The control unit for all roller shutters of a certain complex can be combined with a security console or video surveillance room equipment.
The required height of raising and lowering the blade can be set by adjusting the limit switches. In extreme positions the drive will turn off.
Possibility of installing an automatic lock at the top of the structure.
Electrically driven roller shutters can be integrated into the smart home system.

Diagnostics of roller shutter faults with opening of the protective box

Any repair must begin with diagnostics. It is important not only to identify the malfunction, but also to understand the reasons for its occurrence. This does not apply to mechanical damage, when the cause of the defects is obvious. For example, bent slats as a result of burglary or vandalism.

Most faults are hidden from view under a protective box:

The roller shutter leaf is sagging, skewed or torn
The crossbar blockade on automatic roller shutters has stopped working
The manual cord has broken and the door cannot be opened/closed
The electric motor burned out, the cardan broke, the gearbox failed

As you can see, most of the problems occur with the drive and suspension of roller shutters. A visual inspection of these components cannot be performed without first opening the protective box. In these cases, it is necessary to dismantle the box cover in order to accurately determine the cause of the malfunction and then carry out repairs.

Drilling holes

Installation of roller shutters is impossible to imagine without a drill or hammer drill. You'll have to do a lot of drilling. Needed:

Holes on the back of the protective box. They are drilled into the sides of the box. Fasteners are installed in the drilled holes, which allows you to attach the box to the wall. For greater strength, it is recommended to drill 2 holes on each side for fasteners.
Holes in the side guides are made along the entire length of the tire in increments of 45-50 cm. Please note that the outer holes must be located at least 10 cm from the end of the tire.
Holes in the wall of a building. At this stage, it becomes clear why three people need to install roller shutters. The holes in the wall and the guides must match exactly. The easiest way to achieve this is if two people apply guides to the wall, and a third one marks where to drill.

In addition, if the roller shutters are controlled from the room, it is necessary to additionally drill a hole for the drive, whether manual or automatic. For these works, it is better to use extra-long drills and high-strength drills.

Necessary tool

The tool for installing roller shutters requires the most common one, which almost everyone has at home:

Roulette
Level
Drill with a set of drills of the required diameter
Rivets for sealing holes in guides and frames
Step ladder
Safety glasses and gloves

Some difficulties may arise with concrete walls. A regular drill will not take concrete, so in addition to the main list, you will need to add a hammer drill, dowels and a drill.

Installation algorithm

Installation of motorized blinds should only be carried out in accordance with the manufacturer's instructions. Therefore, before starting any such activities, you should study the official documentation.

The installation process can be divided into several successive steps:

Marking. At this stage, the mounting location is selected, and points for fastening systems are also marked. To simplify this operation, it is performed by several people.
Installation of brackets. To do this, holes are formed in the wall for an anchor or other similar element.
Cabling. Often it is located inside the wall, which requires preliminary formation of grooves. It is also important to choose the appropriate type of wire that will withstand the load.
Installation of cornice and slats. The technology for installing these elements depends on the type of fabric used in the blinds.
Installation and connection of the control system. This process involves connecting the motor to an electrical network. This step also includes setting up all the main controls. In some cases, they even resort to a little programming.

The installation procedure ends with a functionality check. If something is wrong, the serviceability of each element is checked and the problem is fixed. It is better to trust such operations to the specialists of the company from which you purchased automatic blinds. This will not only speed up the time, but also guarantee long-term and reliable operation of the entire system.

Finishing touches and performance check

The hardest part is over. Now all that remains is to connect the roller shutter control system (manual or automatic drive), install locks and limiters. Raise and lower the roller shutter several times to make sure it moves smoothly.

The canvas should not stick, cling or protrude, squeak or grind anywhere.
