Connecting the light barrier - step by step instructions with video tutorials

The principle of operation of the device

So, first let us consider how the twilight switch, you caughtespecially its connection, we give below.

photoelectric design includes three main elements: a photocell, a comparator and a relay.

As for the photocell (and mostly a photodiode, a phototransistor or photoresistor), its main purpose - the analysis of the intensity of light.If the street will darken or lighten the photocell will know about it, on the basis of what will happen on / off light.Comparator - the so-called threshold system.If the voltage supplied by photocell exceeds the set point, the comparator will activate the relay, and thus the lamp.Relay (or triac) is an output device that switches the load (in this case, light).

Simply put, the principle works as follows: when the level of illumination is changed to photoresisto resistance, resulting in increased voltage and relay operation occurs.Result - a lamp, which is connected to the device is turned so far until it starts to get light.

connection diagrams

Before proceeding to install svetokontroliruyuschego switch (another popular name) instead of conventional light switch, you need toto deal with how you want to connect the wires to the terminals of the lamp and the sensor.Thus, the photoelectric wiring diagram for street lighting can be presented in two versions: with and without junction box applications.The first option is common to use when there is a replacement of wiring in the house, becausein this case you will need to display a new line of the back box.

Looks wiring lived follows:

As you can see, the connection of light barrier to the lamp is virtually identical to connect a light switch.As in the normal version, the phase is conducted in the gap, and a zero directly to the lantern.The only difference is that the neutral wire must be got also in itself a photosensor.

If you have already made repairs in the house and did not want to Stroebe wall under a new line, you can use the second option to connect a light barrier with their hands - directly:

In this case, all three wires: phase zero and the ground get turned into the housing and are pressed terminals.Both the first and second mounting method is correct.Choosing the appropriate option you can go further - to install photoelectric their own hands.

Step by Step Installation

Immediately I would like a little bit away from the subject and advise you to simultaneously connect a light barrier and motion sensor lighting.The pair the two devices will include light when it is dark, only if the man appeared detection zone.If anyone will not plot, the light bulb will not light up, which will greatly save energy.

installation method depends on what class of protection and type of mounting twilight switch you purchased.

Today there are a variety of manufacturing options, namely:

• to mount on DIN-rail, on a wall or on a horizontal surface;
• outdoor or indoor use case (depending on the IP protection class);
• photocell built-in or external.

The instructions we give as an example the installation of light barrier for street lighting with the wall mount.Connection is made to stand for the convenience, especially since this is only an example.

So, in order to connect to a light barrier to the lamp, you should do the following points:

1. Turning off the electricity at the introductory panel and check the presence of current in the junction box, which will be carried out by the wire.
2. stretching power cord to the place of installation of light barrier (next to a lighting device).We recommend you to connect a twilight switch to use a three-conductor wire PVA, which has established itself as a reliable and not too expensive option conductor.
3. We clean the wires insulation from 10-12 mm in order to connect them to the terminals.
4. create openings in the cabinet under the institution lived in order to connect to the network and photoelectric lamp.
5. to improve leakproofness, fasten to cut a hole special rubber seals to protect against dust and moisture inside.Incidentally, the twilight switch must be placed so that the bottom openings are input, which prevents the penetration of moisture into the lid.
6. are connecting a light barrier for street lighting in accordance with the wiring diagram, which we have provided above.As you can see in the photo, the introductory phase is connected to the terminal L, and an introduction to neutral N. For ground is a separate screw terminal with the corresponding symbol.
7. Cut the required length of wire to connect the light barrier to the lamp (in reality, it may even be LED spotlight).We clean the isolation and 10-12 mm and is connected to terminals N 'and L', respectively.The second end of the conductor is supplied to the light source and the accession to the cartridge terminals.If the lamp housing is not conductive, grounding is not necessary to connect.
8. Installation and connection is finished, move on to setting the photorelay own hands.There is nothing complicated, complete present special black bag, which is necessary in order to simulate night.regulator (signed by the acronym LUX) can be seen in the light sensor housing, which is used to select the light intensity at which the relay operation occurs.If you want to save energy, turn the dial to the minimum (marked "-").In this case, the signal will be fed for inclusion in the dark outside.Typically, the controller is next to the screw terminals, a little to the left and above (as shown in photo).
9. last step of connecting a light barrier - mounting the protective cover and switch on the electricity board.Once you do this, you can move on to the testing device.

That's all that I wanted to tell you how to install and connect the light barrier with their hands.Also we recommend that you view the graphic video lesson in which the whole essence of the wiring is shown in detail.

Finally it should be noted that some manufacturers twilight switches are the highest quality.To date, it is recommended to give preference to products from companies such as Legrand (Legrand), ABB, Schneider electric and IEK.By the way, the latter company has a pretty robust model - DF-601, which has a lot of positive feedback on the forums.
