As a proud air compressor owner, it is important to understand how the wiring of the air compressor pressure switch works. The air compressor pressure switch is an important component of the air compressor that controls how much pressure is allowed to build up in the air tank. The wiring diagram of the air compressor pressure switch is crucial in ensuring that the air compressor works efficiently and reliably. In this article, we will walk you through the wiring diagram for the air compressor pressure switch in simple and easy-to-understand terms.
What is an Air Compressor Pressure Switch?
An air compressor pressure switch is an essential component of any air compressor. It is designed to control and monitor the pressure inside the air compressor tank. The switch automatically turns on and off the air compressor motor as the pressure in the tank reaches a pre-set level. This pre-set level is adjustable and can be set using the pressure adjustment screw on the switch.
The air compressor pressure switch consists of two main parts: the switch mechanism and the pressure switch control. The switch mechanism is responsible for turning the air compressor on and off at the right pressure points. The pressure switch control, on the other hand, is responsible for monitoring the air tank pressure and turning the switch mechanism on and off as required.
The Wiring Diagram for Air Compressor Pressure Switch
Before we delve into the wiring diagram for the air compressor pressure switch, it is important to know the parts that make up the switch. The main parts of an air compressor pressure switch include:
| Part | Description |
|---|---|
| Pressure Switch | Controls the air compressor motor by turning it on and off as the pressure level in the tank rises and falls. |
| Pressure Gauge | Measures the pressure inside the air compressor tank and displays it on a gauge. |
| Pressure Relief Valve | Automatically releases excess pressure from the air compressor tank to prevent damage or explosion. |
Step-by-Step Guide to Wiring an Air Compressor Pressure Switch
Step 1: Turn off the power.
Before you start working on the air compressor pressure switch, ensure that the power is turned off. This will prevent any electrical accidents that may occur while working on the switch.
Step 2: Remove the cover of the pressure switch.
Locate the screws or clips that hold the cover of the pressure switch in place and carefully remove them. This will give you access to the inside of the switch.
Step 3: Identify the terminals on the pressure switch.
There are usually four terminals on an air compressor pressure switch. The terminals are labeled L1, L2, T1, and T2. L1 and L2 are the power supply terminals, while T1 and T2 are the motor terminals. The power supply terminals are used to connect the pressure switch to the power supply, while the motor terminals are used to connect the switch to the air compressor motor.
Step 4: Connect the power supply to the pressure switch.
Connect the power supply wires to the L1 and L2 terminals of the pressure switch. The power supply wires are usually black and white.
Step 5: Connect the motor to the pressure switch.
Connect the air compressor motor wires to the T1 and T2 terminals of the pressure switch. The motor wires are usually red and black.
Step 6: Reconnect the cover of the pressure switch.
After you have connected the wires to their respective terminals, carefully put the cover of the pressure switch back in place and secure it with screws or clips.
Frequently Asked Questions (FAQs)
What is the purpose of an air compressor pressure switch?
The main purpose of an air compressor pressure switch is to control and monitor the pressure inside the air compressor tank. The switch automatically turns on and off the air compressor motor as the pressure in the tank reaches a pre-set level.
How do I adjust the pressure on my air compressor pressure switch?
You can adjust the pressure on your air compressor pressure switch by using the pressure adjustment screw on the switch. To increase the pressure, turn the screw clockwise. To decrease the pressure, turn the screw counterclockwise.
Why is my air compressor not turning on?
If your air compressor is not turning on, it could be due to several reasons. One common reason is a faulty pressure switch. Check the wiring and connections on the pressure switch to ensure that they are secure and properly connected. If the problem persists, consider replacing the pressure switch.
How often should I replace my air compressor pressure switch?
There is no set time for replacing an air compressor pressure switch. It all depends on how often you use your air compressor and the condition of the switch. However, if you notice any signs of wear and tear or any malfunctioning, it is advisable to replace the pressure switch as soon as possible.
What safety precautions should I take when working on my air compressor pressure switch?
When working on your air compressor pressure switch, ensure that the power is turned off. Wear protective gloves and avoid working on the switch when the air compressor is pressurized. Always follow the manufacturer’s instructions and guidelines when working on the pressure switch.
In conclusion, understanding the wiring diagram for the air compressor pressure switch is crucial in ensuring that your air compressor works efficiently and reliably. Always follow the manufacturer’s instructions and guidelines when working on the switch to ensure your safety and that of the equipment. Following these simple steps will ensure that your air compressor pressure switch is working optimally for a long time.
