The BUOK-1 SVT667.13-111 block is an automated device required to control the power supply of the electric drive of the fire dampers.

In standby mode, the circuit of the BUOK-1 SVT667.13.111 unit is closed. When a special button is pressed or a signal is received about an unexpected fire, the circuit is opened, which activates the fire dampers.

The blocks of the type BUOK-1 SVT667.13-111 manufactured by SVIT allow to minimize the chance of an unforeseen fire in production, regardless of what caused the incident. The device itself is reliably protected by a metal case that can withstand high loads and mechanical damage.

On the front panel of the body there are three indicators that clearly demonstrate the state of the control unit: "standby mode", "valve is actively working", "control mode". On the upper side of the case there is a red button, pressing which brings the BUOK-1 control unit out of standby mode. Due to its design, the fire damper control unit can be attached to one of the walls or any other vertical surface.

Finally, in order for the control unit developed by SVIT to work smoothly, it is necessary to provide the device with 24V DC.

BUOK-4 ANALYSIS

Today we will tell about BUOK-4 production SPF "SWIT".

Interestingly, the production is certified by ISO9001.
Well, what else to add, there must be quite a decent production, there must ... be ....

I had the misfortune to get to know them at the lectures given to us by the specialists of SPF "SVIT", the lecture was immediately after the exhibition on fire safety.
And the devil pulled me there to go ...
No, of course they read lectures well, they loaded us in full.
Such eloquence would be for them, some time later ...

Realizing that time is the most valuable thing on this planet, I will still spend a little more by posting a description of this craft.

At the same time, by the way, we will touch on their shields. ShK-S.
But the shields, of course, were more fortunate, they are simpler, and the electricians who assembled them do not have the same flight of thoughts that the "engineers" have. NPF"SWEET", the creators of the" masterpiece " BUOK-4.
Okay, let's get started, let's start gutting this miracle of engineering ...

Divide our analysis into stages:
1. Electrical schematic diagram
2. Analysis of the electrical circuit diagram
3. Design features of the product
4. Analysis of the operation of the product in combat conditions
5. Recommendations
6. Overview of shields ShK-S

Let's start with the diagram of this "device", which the "engineers" stubbornly refused to give me the diagram. NPF"SWEET", arguing that it is KNOW-HOW.
And I see a complete goof, because I am not able to customize this wonderful work of art.
I had to spend a day sketching the diagram.

Frankly speaking, If I was given a diagram- then this article would not appear on the Internet.
But on the part of the "engineers" NPF"SWEET"there was absolutely complete indifference to my problems, which was superimposed on sarcasm, and this in relation to my desperate attempts to deliver the job on time.

There are two schemes, version 3 and 4, they are almost identical except for the little things, which one is more accurate, I don't remember, in principle the principle of operation is important, and the schemes are for convenience.

Scheme BUOK-4, (3rd version, click to enlarge)

ANALYSIS OF THE CIRCUIT OPERATION
Selection of element base, SMD resistors and capacitors, damping voltage, stabilized power supply, LEDs, statuses.

1. Let's start with the element base.

Usually, they try to unify the element base, that is, a decision is made about SMD elements or DIP and then work only with them is going on.
If a "Soviet" element base is used (well, this cannot be avoided), then they try to put it on less critical areas of work, these elements, and so on.
In BUOK there is a cross, and the logic of the use of certain components is completely incomprehensible.

This is what we see in BUOK - on Statuses(for example 1 channel: R1, R2, R3, C1, C2, C3)
Powerful SMD resistors are used there in total 19 Pieces, and high-voltage capacitors SMD in total 18 Pcs - these items are enough Expensive And I think they pull a total of about 20-30% of the cost of the product.
Why, for what purposes and tasks are such expensive components used ?!
Why aren't cheaper elements applied?
After all, there is a lot of space, and the site is not very important ...
Well this is a rhetorical question.

And right there, To a very important area, put a wonderful "Savetsky" button START", to whose" impeccable "work we will certainly devote a whole paragraph!

The original, let's say, technology for the selection of components!

We will come back to the power supply decoupling, but now let's see how this scheme is implemented.

The input voltage is extinguished across resistors and a capacitor (important section), which is then fed to Domestic assembly KTs407 and is stabilized by a zener diode coupled with a capacitor!

This circuit design is very dependent on the parameters Networks And parameters Components And the capacity of the extinguisher Capacitor(shamanism)
It is visible here " Care"about economy Products! - and this is after application Dear SMD high-voltage capacitors + Dear powerful SMD resistors!
And the setting! They beat the shaman tambourine when setting up the scheme, not otherwise.
Let's see what loads are not so small: 3 powerful gluttonous relays and a scattering of transistors who also want to eat.

As a result, circuit solutions for the stability of the unit " Acquitted"myself completely, I had to customize each product individually, in one word" Industrial"automation.

Another feature, the circuit has the ability to select power from 3 sources 220V, 24V, 12V, which " Wise"solution and savings!
Adjustment is carried out, without further ado, - jumpers!
Looks like an impulse power supply (transformer at worst) - the engineers of SPF SVIT have a redundant element
Indeed, why is it needed if there are resistors, capacitors and a zener diode.

By the way, one of these "power supplies" after a month of work, I just exploded - KTs407, and only charred legs remained from the resistors.

Absolutely incomprehensible economy, selection of elements and technology, in a rather serious product.

3. A very interesting approach to the applied LEDs in the status chain!
The LEDs are imported (price) and very sensitive (interference), they glow from a milliampere, and since we have the induced mains voltage on the statuses, it is absolutely impossible to get rid of it (one more Super feature Products) - that's why statuses turn into light and music.
It is rather difficult to explain to the customer why statuses (LEDs) work randomly.
Although in fairness it should be noted that if the valve hangs next to BUOK-4- well, 5 meters away, then the LEDs behave sanely.
But how often, on Real object, it happens, besides this BUOK-4 designed for connection 4 Valves, and 4 The valve is nearby ....

4. Even more original circuitry solution, used for the operation of the status relay K3-K5, I can't explain such a flight of thoughts (I'm not a shaman), I'd rather skip this point, there are no words - only interjections ...
look better for yourself ...
And think how THIS IS Customize, in real conditions, and not on the designer's desk ...

DESIGN FEATURES OF THE PRODUCT
Case quality, button Start, housing cover, access during routine maintenance, do not confuse zero and phase!

1. Frame BUOK- a rough stamped square iron box, covered with powder paint, with a glued picture showing the modes of operation of the product.
The board is mounted on four metal racks, which, by the way, break very easily and some blocks came with broken racks.

2. The funniest thing is that the BUOK power button is hidden inside the BUOK case! A! What is it!
To turn it off, you need to remove the lid, but do you think it's easy? Okay, more on that later.
By the way, I didn't immediately understand the whole brilliant idea of ​​the designer!
Remember we said that the circuit has no power decoupling!
Remember these 2 points !!!

3. We need to mount the product - Let's get started!
The design cannot be easily disassembled, first you need to unscrew 4 bolts at the edges, Attention, the stamp that is used to make the body BUOK-4, is terribly torn, therefore Label caps, they are individually adjusted for each box (a hammer helps, a wooden one is desirable).

4. Having removed and marked the cover, you will see our board, remember that the circuit does not have power decoupling, therefore For security Supply power through Separate knife switch (switch)!

And remember EVEN IF YOU TURN OFF THE POWER, on the board BUOK-4, Via local switch-off button - mains voltage EVERYTHING IS EQUALLY PRESENT ON THE BOARD! Therefore - an external switch!

But the switch is also inconvenient, because you will not bet on each BUOK by the knife switch?
After all, if there are 3 blocks hanging next to it, and in order to de-energize one, you need to cut off the power supply at all 3 or put 3 switches - Nice isn't it ?? Congenial!

5. The instructions state that IT IS FORBIDDEN Reverse phase and zero when connecting power BUOK-4.

I'll " I will calm", cling As you wish, all the same, the assemblers of this product connect the power wires from the power button to the board As they please so your efforts are in vain.

6. During installation Especially carefully Get around the button " Start"if you accidentally hit her, check her work.
The peculiarity of this button is that its contacts are pressed into the body of the button and are held there solely by the force of friction.
Therefore - I draw your attention once again - carefully, and PUSH THE BUTTON AS FAST AND Smoothly as possible, DO NOT PUSH HARDLY !!!

I lost about 10% of the buttons, although they are easy to repair and quite cheap.
But, imagine my surprise, the first time when the block itself was triggered due to the failure of the button (contact fell out), On working supply machines and that nasty button blew up the air ducts before the differential pressure protection kicked in!
Are you having fun !? - Me too!

7.
But routine maintenance is not boring to carry out, you understand why you are paid money, but I strongly recommend buying rubber gloves.
I share a secret, electric gloves are rather rough and uncomfortable - I bought surgical ones, I liked them, although my hands are sweating.

And be sure to do Good Grounding, otherwise you never know what will happen with such a structure.

WORK IN COMBAT CONDITIONS.
What can be said about the operation of this product in combat conditions, so to speak - they work, but ...
But I pray for the time when the warranty expires.
Now the obvious problems are:
1. The "Start" button is buggy - but fortunately it is quite rare, basically these glitches are eliminated during the commissioning process, then it is normalized.
2. High-quality food is very important (again - there is no galvanic isolation and all the garbage that flies over the network - flies to BUOK).
There were cases of spontaneous operation of the BUOK, and for a long time could not understand what was happening, he cured it by supplying power from another input.
3. Very poor noise immunity, which manifests itself in the arbitrary glow of the led diodes, is difficult to treat, shielding will not help (see the diagram). How to treat? To be located as close to the valve as possible, which is understandably not always possible, and (or) replacing an imported LED with a domestic one. Grounding helps weakly.

BRIEF OVERVIEW OF SHIELDS ShK-S
1. Apply Only Domestic components, and the price is very decent, obvious Inconsistency Price quality!
2. The assembly is disgusting, Stretching EVERYTHING is mandatory!!!
3. Pay attention - Collectors save On ferrules, instead of using double ferrules, they insert Wires of different cross-sections in one terminal!!! VERY DANGEROUS!
I had equipment malfunctions because of this !!!
3. Half The shields did not turn on, the problems of the collectors - Collected shield does not match Electrical schematic diagram.
4. The wires are all Of one The colors are extremely uncomfortable!
They are so saving on us!

Conclusions: I do not work with SPF "SVIT".

P. s. By the way, the managers of the SPF "SVIT" are quite sane people, unlike the "constructors" they tried to help ...

Copy & Paste by 13th department

The unit consists of a housing with a push-button switch, a printed circuit board with an electronic executive part located on it, light indicators for monitoring the presence of supply voltage and the position of the damper flap, and a fuse.

In the standby mode of operation, two green indicators are on: "control" and "standby mode". The yellow color of the "control" indicator indicates an intermediate position of the valve. After the valve is triggered, the yellow indicator "valve triggered" lights up and the relay for signaling the operating position of the valve turns on (contacts 11-12 close, 13-14 open).

Power cables, valve electric drive, valve flap position sensors, automatic control signals and signaling of the operating position of the valve flap of the fire alarm system, control are connected to the block terminals (for example, ASPS02-33-0000 BSU, TU4371-023-23358046-99)

Control

Automatic (remote) control of the valve is carried out by supplying the unit with a command signal of 24V DC or 220V 50Hz (control current no more than 100 mA).

In manual mode, the valve is controlled by the SB1 button. The control units for solenoid valves use a push-button switch without fixing the position of the contacts, while the control units for valves with an electromechanical drive such as “Belimo” or “Polar Bear” use a push-button switch with fixing the position of the contacts. In valves with single-phase reversible drives ("DSRK"), a button with contact fixing is also used.

Installation

Install the blocks on the walls of the room, in accordance with the plan
placement of equipment. Mount to the wall with self-tapping screws 3x20.

Install units in a plastic housing on a DIN rail in an electrical cabinet.

Connection to the valve and power cables is made according to the external connection diagram.

Storage conditions

The BUOK unit, prior to commissioning, must be stored under conditions I in accordance with GOST 15150-69.
Under the specified storage conditions, the permissible shelf life before entering into
operation - 2 years.
