how to wire pressure switch on air compressor

A pressure switch is an essential device employed in an air compressor system to properly and safely control its pressure. Reaching a predetermined level, it shuts off the system and creates a safe environment. In this informative article, we’ll learn how to wire a pressure switch on an air compressor to ensure that it runs smoothly and efficiently.

Understanding Pressure Switches

Pressure switches serve an important function in controlling the pressure levels of systems that rely on compressed air. Utilized for both safety and convenience, these devices operate to automatically shut off a system when a pre-set pressure is reached. Although most commonly found in air compressors, pressure switches can also be found in equipment such as water pumps and fuel pumps.

Unveiling the Functionality of a Pressure Switch

While the system is running, the pressure switch monitors pressure levels in the air. As soon as the pressure reaches either its highest or lowest limit, predetermined by the switch’s settings, it will activate and abruptly stop the system. Generally, a pressure switch will be set to a particular array of pressures which dictate when it will switch on or off.

Mastering the Basics: The Significance of Pressure Switch Wiring

It is imperative to wire a pressure switch correctly to guarantee that it functions optimally. When wired incorrectly, the pressure switch may not be able to detect the system’s pressure, potentially resulting in system overheating and extensive damage to the compressor and other parts.

Electric Current on the Move: Setting Up a Pressure Switch

Connecting a pressure switch correctly is an easy job to complete, yet prior to starting the task, it is essential that the wiring diagram is comprehended. The diagrams will demonstrate the linkage between the pressure switch and other components part of the system.

To get the pressure switch up and running, the initial move is to sever the power supply to the system. An easy way to do this is by switching off the circuit breaker or unplugging the compressor. Once the power source has been terminated, it’s appropriate to set up the wires with the pressure switch.

On a pressure switch, you’ll find four terminals. Two located on the outer side of the switch are labeled “L1” and “L2”, while the two located on the inner side have been given the designations “N” and “P”. The power for the device should be connected to the former pair, while the latter is typically where auxiliary components come into play.

The power source needs to be paired with the L1 as well as the L2 terminals. The air compressor requires being attached to the N terminal, while the pressure gauge and P terminal must also be joined. After the wires have been linked up, your pressure switch should functional and ready to use.

Consequently, installing a pressure switch on an air compressor shouldn’t be too difficult of a process. One should take the time to examine the wiring instructions thoroughly before attempting it and always double-check that the power source is off. Upon completion of the wiring, the pressure switch will be able to identify when the desired air pressure is reached, and shut down the system accordingly. In this way, it will safeguard against any unwanted or dangerous situations.

Electrical Connections for Air Compressor Pressure Sensors

Utilizing your air compressor to its fullest potential requires knowing how to wire a pressure switch correctly. A necessary aspect of all air compressors, the pressure switch takes on the task of regulating air pressure and automatically turning the compressor off at a certain limit. Identifying this process can seem daunting – so here we provide a helpful guide on how to wire a pressure switch for an air compressor.

Assemble Key Elements

Prior to attempting to wire up a pressure switch, it is important to be sure that all of the appropriate items are at your disposal. You’ll need the pressure switch itself, as well as a wrench, wire cutters, electrical tape, and last but not least, a screwdriver.

Cut the Juice: Disconnecting the Power

To prevent any dangerous shocks or accidents, your initial step when dealing with any type of electrical work should be to cut off the power supply to your air compressor. By simply unplugging the cord or flipping the circuit breaker switch, you can take the necessary precaution of disconnecting the energy source.

Prepping the Power Cords

After unhooking the energy source, it’s time to ready the cables. You’ll need to recognize which cables will be tied to the pressure switch, typically indicated by color. The usual code is red for energy input, black for mission load, and white for ground.

Step 4: Joining the Circuits

With the wires identified, you can commence the process of connecting them to the pressure switch. First, join the red wire to the “L1” slot in the switch. Subsequently, connect the black wire to its corresponding “L2” port. And finally, affix the white wire to the terminal labeled “G”.

Attaching the Cables: The Final Step

After linking up the wires to the pressure switch, it is necessary to confirm that they are safe and secure. This can be achieved by utilizing electrical tape to firmly bind the wires around the connections.

Putting in the Pressure Switch – The Finishing Touch

The pressure switch installation must be the next step. Confirm that the component is switched to the “off” position before affixing it with a screwdriver to the machinery of the air compressor.

Final Step: Establishing the Pressurised Connection

The next step is to get that pressure switch connected to the air compressor. Utilize a wrench to attach the switch’s power source to that of the air compressor’s. You’ll also require the same wrench to then couple the switch’s load with the compressor’s. Finally, use the same device again to tie together the ground of your switch and air compressor.

8th Phase: Regain Electricity

Finishing the project, connecting power to your air compressor is the last task in line. To perform it, flick the switch on the circuit breaker or attach the electric cable.

It’s cause for celebration- you have finished wiring a pressure switch to your air compressor with great results! You are now equipped with the knowledge of how to utilize your air compressor to its fullest potential. While electrical work has the capacity to be precarious, always ensure appropriate measures for safety are taken.
