Have made the pressure switch wiring direct, and now your air compressor is not operating properly; you are not the only one out here making this mistake. Many beginners and even electric workers do this when wiring because of a lack of research and prior machine knowledge.
Now, when you are here, I must say better late than never realizing what’s going wrong and where to go for help. This article will prove a beneficial source for you once you will read it and implement it to rewire your pressure switch.
We will start with how to wire a pressure switch on an air compressor, and in the next section will discuss the safety measures one should take while wiring. Moving on, if you still don’t get the understanding, we have another section devised for you. Lots of information and lesser time, jumping straight into the first section now!
Step-by-Step Guide on How to Wire Pressure Switch on Air Compressor
Wiring a pressure switch or any other task related to an air compressor isn’t tough as we expect it too. The air compressor is a universally used device for thousands of purposes and is used by almost every person belonging to different professions.
Concerning so, more than 80% of air compressors are made by keeping this all in mind. If your air compressor is acting up, you can also be a pro with your device. Here’s how you can ace it:
The tools you’ll need to wire the pressure switch include Solderless ring terminals, screwdrivers, and wire strippers.
Step 01
The most important of all is turning the electricity of the air compressor off. You must always turn off the air compressor before starting the wiring as it can leave you in hazardous conditions, and you’ll not comfortably and efficiently do the task.
In another case, the pressure activates and deactivates the machine’s motor. It helps to manage the tank’s internal pressure. If you unplug the compressor without first disconnecting the switch, you could be injured.
Step 02
Now, you will locate four terminals, making two sets. These terminals are sometimes marked, but not all air compressor manufacturers do. Moving to the markings, they state as line and motor.
Before going further with it, let me clear a few things to you. There is a connection between the pressure controller terminal and the wall outlet through the power cord. A connection between the motor circuit and the pressure controller is made by the motor cord.
Step 03
In the next step, as I talked about the connection, there is also one thing there are markings of color green, black and white. Some experts recommend marking the wires, too, but if you don’t want to start by measuring the lengths.
In addition, it is recommended when wiring the switch that the black wire always connects to the left motor line contact and the white wire to the right. The green ground wire is on the left.
Step 04
Connect the power source’s cables to the pressure switch’s interface screws. Some cords are welded; others aren’t. So, connect the cord to the interface. You must fuse certain wires that aren’t easily separated.
Strip the wires using a wire stripper and reconnect them. Check contact markings and unscrew the screws. After that, connect the cords and screws.
Step 05
In the final step, you will need to reinstall the switch cover, turn on the circuit breaker, and activate the compressor. Check to see that you have properly reassembled everything and that all of the terminals are connected and in contact with one another.
Safety Tips to Wire Your Pressure Switch with an Air Compressor
- Always make sure to examine the functionality of the pressure switch on your air compressor so that you can anticipate whether or not it will need to be repaired.
- Before beginning the wiring process, you should give some thought to putting on protective clothes such as gloves.
- In order to prevent the risk of being shocked, you should make sure that your hands and the ground surrounding you are dry and free of water.
- Check that the wires you plan to join have the appropriate insulation before continuing.
- Verify that you are connecting the appropriate terminals by carefully rechecking the terminal markings and the wire colors before connecting any cables or ports.
- Before beginning any work, the primary source of electricity must have its switch turned off.
- If you are going to replace a pressure switch, you have to be sure that the new switch is compatible with the air compressor; otherwise, you will be wasting both money and time, in addition to perhaps putting yourself in serious trouble.
Working of a Pressure Switch in an Air Compressor
Your compressor’s pressure switch is vital and most important for running an air compressor. It stops the compressor until the right pressure is reached. Alongside this, it also ultimately stops the motor and prevents the equipment from being damaged.
The compressor’s tank contains the switch. To know about the location for operating, open the tank to observe the pressure gauge and you will find the pressure switch next to the gauge. On either side of the pressure regulator is a port where an airline can be attached, where one line is tank-fed.
Furthermore, here the supply line connects the tank and pressure controller. Your air compressor has a switch that cuts power to the unit if the pressure goes too high. This prevented the machine from breaking because the pressure was too high.
Moreover, the pressure control switch makes use of an electric control valve to turn on and off an electrical circuit in order to achieve the desired effect of controlling the flow of electricity. That’s pretty much all how it works.
Final words
Not all the parts of an air compressor are important to be well managed and maintained, but the pressure switch is an integral part on which major functioning and performance depend. You might require to do the wiring of the pressure switch again and again because of its excessive use in air compressors.
Other than that, I believe this information on how to wire a pressure switch on an air compressor is quite enough to perform the task. If you do, please leave your feedback!
