An air compressor pressure switch is an important component of any air compressor. It monitors the pressure inside the tank and shuts off the motor when the set pressure is reached. To ensure the pressure switch is wired correctly, it is important to understand the wiring diagram. This article will provide an overview of the basics of a pressure switch and how to wire it correctly.
Understanding the Pressure Switch
The pressure switch is designed to turn the compressor motor on and off when the pressure in the tank reaches a certain level. It is usually connected to the pressure gauge, which is used to measure the pressure in the tank. To ensure the pressure switch works properly, it is important to understand the different settings. These include the cut-in pressure, which is the pressure at which the switch turns the motor on, and the cut-out pressure, which is the pressure at which the switch turns the motor off.
Wiring the Pressure Switch
When wiring the pressure switch, it is important to follow the wiring diagram provided in the manual. The diagram will show the different connections and their purpose. If the pressure switch is wired incorrectly, it may not work properly and could cause damage to the motor. A typical pressure switch wiring diagram will include a power source, a pressure switch, a pressure gauge, and the motor. The power source should be connected to the pressure switch, then the pressure switch should be connected to the pressure gauge, and finally the pressure gauge should be connected to the motor.
Conclusion
A wiring diagram for an air compressor pressure switch is a valuable tool when wiring the switch correctly. It is important to understand the different settings and to follow the wiring diagram provided in the manual. Doing so will ensure the pressure switch works properly and will help to prevent damage to the motor.
