The PVL time delay attachment is used in relay automation devices where a time delay is needed. It is used less and less, but in electronic devices time delays (on-off delays) are very similar - both the principle and the designations on the diagrams.

The time is set manually using the rotary control at the top of the console. The color of the regulator can be blue (as in the photo on the left) and black. Why this is important - read the article further.

Naturally, there can be no talk of any accuracy of the established time. Maybe that's why intermediate times are marked with letters. Where else is time indicated in Russian letters? Isn’t this a sign that nothing can be guaranteed?

It is worth saying right away that such a relay is currently practically not used in new devices. Basically, for the listed purposes in industrial automation, electronic time relays or controllers are used.

Information on the Internet is scarce and scattered, I hope this article will be informative, since I am posting everything that I have dug up and systematized on this topic. As always, there will be photographs, diagrams, and practical recommendations.

Due to the principle of operation of the PVL attachment, it is also commonly called pneumatic attachments, pneumatic attachments, pneumatic timers, pneumatic time relays, pneumatic delays, etc.

Application of time delay attachments PVL

The set-top box acts as a timer, providing the necessary delay according to technological process or the principle of operation of a relay circuit.

Here are the areas of application of PVL that I can list offhand:

• Star/Delta motor connection diagram. In this case, the PVL acts as a starting relay, turning on the motor in the “Star” circuit, and after a while - in the “Triangle” circuit.
• Filtering of contact bounce of limit switches and sensors, response delay
• Watchdog timer - if some function is not performed within the required time, then emergency protection is activated, stopping the technological process.
• Work in cyclic systems – time “there”, time “back”, pause between cycles

Symbol

In the name of pneumatic attachments, the first digit is the operating principle of the delay: 1 – delay after switching on, 2 – delay after switching off. Therefore, in the future in the article I will call such relays PVL-1 (on delay) and PVL-2 (off delay)

The second digit is the delay time: 1 – 0.1…30 s., 2 – 10…180 s., 3 – 0.1…15 s., 4 – 10…100 s. Depending on the manufacturer, with the same name, the range of exposure time may be different.

Most famous models pneumatic time relays – PVL-2104 (on delay), PVL-1104 (off delay).

Here is an example - the side of the console, which is given at the beginning of the article:

PVL-12 04 - side view of the label

For comparison, the PVL-2 label:

PVL-2104 - side view of the label

Consoles PVL-1 are blue adjustment knob (see photo at the beginning of the article), this is a standard for all manufacturers.

Consoles PVL-2 with a delay after shutdown have black adjustment knob.

Design and principle of operation of the PVL pneumatic attachment

For PVL attachments, the operating principle is based on mechanics and pneumatics. That is, when the attachment is cocked (activated), the contactor acts so that air comes out of the rubber reservoir. Then the countdown begins as the tank fills with air. When a certain amount of air is drawn, a lever is pressed, which acts on the contacts.

Below are photos of disassembled PVL consoles.

Contacts and designation on electrical diagrams

Now - the most interesting thing, what is as close as possible to practical application.

There are always two contacts in such set-top boxes - Normally closed And Normally open(NC and NO). This applies to both PVL-1 and PVL-2. The normal state is the initial state, the state of the circuit without power.

I wrote more about the types and principles of operation of contacts in the article about.

What follows must be clearly understood if you encounter such prefixes in your work.

PVL-1 – designation of contacts with a delay when switched on electrical diagrams

PVL-2 – designation of contacts with a delay when disconnected on electrical circuits

Do you see arcs that seem to activate contacts? In “blue” relays (on delay), the ends of the arc are turned to the right, like the letter “ WITH“.

In “black” relays (switch-off delay), the ends of the arc are turned to the left, like the letter “ E“.

These symbols are often used on electrical circuit diagrams, including to designate electronic relay contacts.

I came up with a mnemonic rule for myself that helps to easily remember the functions of PVL prefixes:

Power-on delay: 1-C-blue

Power-on delay: 2-E-black

Here is a summary diagram-table-poster for PVL attachments (time relays), which I recommend printing out and hanging in your workplace:

Poster PVL. Designation and functions

Operation of the pneumatic attachment with a delay when turned on.

Let's take a closer look at the operation of a pneumatic time relay with a delay when turned off. PVL, as well as PKI, always work only in tandem with a contactor; they do not have their own drive.

Let me remind you that PKI consoles look like this:

PKI. From below

And although in the photo there are IEK KO1 DN22 attachments, PKI is a common noun, like Xerox is for a copy machine.

I also wrote about PKI in an article about.

The attachment has mechanical contact with the contactor on which it is installed. When power is supplied to the contactor, it is actuated (retracted), and the attachment is actuated (retracted). If this were a regular PKI-type contact attachment, then the contacts would immediately go from normal to active state.

But in set-top boxes with a delay when turned on, the countdown begins, and only after that they go into the active state. That is, normally open contacts close, normally closed contacts open.

In other words, after power is applied, the contacts are activated (transition to the active state) not immediately, but after set time.

Operation of the pneumatic attachment with a delay when switching off.

Here the situation is different - after power is applied, the contacts go into the active state immediately, like with a regular PKI set-top box. But after turning off the power, the contacts do not return to normal immediately, but after a while. The delay time starts counting immediately after the power is turned off.

Timing diagram of PVL-2

You don’t have to assemble the circuit, but check the operation in a quiet room. To do this, you need to put the PVL on the contactor and press the lever on the side (right). After the set time, the PVL will click, it will be clearly audible. And before pressing and after the click, you can measure the resistance of the contacts, which should be no more than 2 ohms in the closed state.

PVL repair

There is an opinion among electricians that such set-top boxes cannot be repaired. This is only true for the mechanism, which consists mainly of plastic parts. And the contacts can be easily cleaned, as in conventional relays or PKIs. You just have to carefully unscrew the four self-tapping screws with a thin cross-head screwdriver, and access to the contacts will be excellent, as in the photo where the PVL device is shown.

It is also worth saying that when working in dusty rooms, the consoles quickly break down - the mechanics and pneumatics work poorly (time flies too much), the contacts become clogged.

Electronic platform scales PVE, mod. PVE-500, PEV-1T

The product is registered in the State Register under number 16983-98

Purpose and scope

Scales are designed for static weighing of various cargoes during accounting and technological operations at industrial, agricultural and commercial enterprises.

Description

The principle of operation of the scales is based on measuring the deformation of the elastic element that occurs under the influence of the mass of the load being weighed, with subsequent processing and indication of the weighing result.

The scales have a load receiving device consisting of a frame, a lever mechanism, a stand with a control and display unit and a network cable with a power supply. An elastic element is installed in the rack - a strain gauge load cell, connected to the lever mechanism through a rod.

The scales are produced in two modifications: PVE-500, PVE-1T, differing in the highest weighing limits and values ​​of standardized metrological characteristics.

Scales are optionally supplied with an output connector for communication with a computer, with a function for calculating the number of products in pieces, as well as with autonomous source power supply (battery) in any combination.
