If you are a physics nerd, you already would be well aware of the start-stop circuits. These circuits have a huge significance for the fine performance of electrical devices and industrial machines. A slight fault in the start-stop circuit can create a negative impact on the equipment leading it to proper failure.
Hard to believe, right? The role of such a circuit is to start and stop a device. In this post, we are going to decipher the start-stop circuits in detail for you. Consider it a refresher or new information as per your situation. Start-stop circuits, here we go!
What Is A Start-stop Diagram?
You can define a start-stop circuit as one of the types of regular electrical circuits that enable you to start and stop several devices, systems, and machinery. In fact, you can use them in motors as well. These circuits are useful for the standard performance of such equipment that commands it to start and stop at a particular time. Or else it can undergo complete damage due to dysfunctioning.
These circuits consist of several small and large components and wiring networks. The circuit might also act as a relay, contractor, or even an entire motor in some cases. Pretty amazing, no? The ultimate goal is to seamlessly command a device so that it can function properly. Now don’t think that there are no options when it comes to these circuits. These are available in different sizes, types, and features as per your requirements.
It’s time that we spare no effort to learn about the critical parts of these circuits!
Components of Start-stop diagram
· Buttons/Contacts
These buttons are actually “push buttons” that pair up with contacts in a start-stop circuit. These components are responsible for powering the circuit and breaking this power as well. These can start and top the switches on the same phenomenon as well.
· Relay/Contactor
It turns for relays and contactors. It is another duo of important circuit components. Now these components are basically the managers of other parts located on a start-stop circuit. After all, you need something to manage other components and their functioning as well, right? Let’s take the example of a motor. When you start the power, the coil present in the contactor will ultimately charge the motor by producing voltage.
· Motor
The motor is also a part of the start-stop circuit. The control offered by these circuits is necessary for the industrial conveyor belts and factory machinery that are always moving from one area to another. The motors that use start-stop circuits are efficient in producing kinetic energy by recycling electrical energy in seconds.
· Overload
Overloads, aka protection devices, are for pricing security to the sensitive wires and components of these circuits. These are the guards of a start-stop circuit that stabilize the system. Also, these prevent all the potential risks of failure and abrasive damage to the circuit. Sometimes the circuit can undergo overvoltage and overcurrent, for which overloads come in handy.
Requirement of Electricity Supply For Start-stop Diagram
As you know, no circuit can work without an appropriate electrical supply. For start-stop circuits, there is also a special electrical supply system that you need to know. One common system is 24V DC, aka control voltage suitable for the start-stop circuits. You can change the voltage as per your circuit and its components. Now here’s something important:
- If you’re going with a 24V supply, then you need to seaport the motor’s own supply and the control voltage.
- It will help you lower the voltage on all accounts.
- You need to do this step so that there will be a seamless connection between the motor and the voltage supply.
- The start-stop circuit will guide the contactor for releasing and stopping the power to the motor as well.
Working on a Start-stop diagram
It’s time to learn about the working of a start-stop circuit system. In this section, we will see how each and every component of this circuit contributes to its performance. You can use the voltage within 24V-400V+. It is recommendable to use 24V on a regular basis.
· Other Start-stop Circuits
Remember we told you that these circuits are of different types? Let’s see one of them below:
· Start-stop Jog Circuit
If you press the start button, it will allow the current to make its way through the push button. It will reach the contact where the contact’s copper coil will generate power for the device. After this, you can leave the start button, and the current flow will remain the same as well. Now if you need to stop the motor’s coil from producing energy, you simply need to learn about some common methods.
Yes, there are multiple ways that you can do this step. In case the motor is overlading, it will cause the contacts to open quickly. When you press the stop button, it will automatically stop the power from going toward the contact. It means now you have successfully de-energized the coil. You can also use a jog state for the same purpose. It influences the lock to stop generating power that will cease the power to the contact.
Summary
Today, several industries are handling rigorous electrical and mechanical operations that need safety and quality control. Not only this, the producers need to ensure the protection of expensive high-end machinery and of the workers.
For this, always rely on a controlled, systematic pipeline of the workflow so that there would be little or no chances of any mishaps.
A little start-stop circuit can save you from a huge problem later. Since the domain of automation is progressing at a rapid pace, these circuits are also undergoing productive changes.
Therefore using automated circuits for your future projects will not only promise quality performance, but it will also save you precious time as well. So was this post intriguing enough for you to switch to start-stop circuits? If yes, then don’t delay to stun your clients by using start-stop circuits in your next inventions!
