Do the same on the other side with the green wires. The switch can turn on your compressor when tank air pressure levels drop and more air is needed. Pull the cover off of the switch (if i have to tell you to unplug it first, then you’ve got more problems than i can solve). Now you always have an high enough pressure in your compressed air system, and you made sure that the compressor stays healthy by not having it start and stop all the time. It is measured in Amperes (Amps), as well as can just flow when a voltage supply is connected. Discussion in 'Plumbing and Central Heating' started by Juliepowell, 29 Feb 2012. How to Video: Properly Wire your Air Compressor's Pressure Switch. Loosen (do not remove) the screws on the pressure switch terminal with a screwdriver by turning in a counterclockwise direction. Together with the pressure gauge, it determines whether there is a need to deliver pressure in the reservoir or receiving tank when the content gets too high or low. These are the fundamentals and may even appear evident or instinctive to you, such as the cables as well as if they are attached. We'd welcome it here!

Plug in the compressor plug and you have power flowing to the air compressor, through (perhaps) an ON/OFF switch and to the pressure switch, and if the pressure switch is closed, power will flow through it to the start capacitor on the air compressor motor. A wiring diagram is a simplified traditional pictorial depiction of an electric circuit. The name brand of the switch is Furnas electric co. Hello, and thank you very much for writing in. You will likewise learn concerning the numerous icons used for buttons, various other power materials, inductors, meters, lamps, LEDs, transistors, antennas, and also a lot extra. When the fan operates effectively and air is proved at the air pressure switch, the micro switch moves to the proved air flow position NO terminal. Locate these and wire the white from the wall to the moving contact and the white from the motor to the fixed contact. Rewire the pressure switch to the "coil" so that it can pilot the Mag. Our pressure switches are field adjustable. i did think i would … Those are the cord side, and the black wire and the white wire from the power cord side gets wired to  each of those. Electrical outlets in various other countries run at a different voltage, which is why you require a converter when taking a trip. This makes your air compressor pressure switch a part that gets used often, and so it may wear down sooner than others. First of all I’m quite sure there are SOME kind of schematics on a sticker or molded into the plastic, but if not, do this…. First get the wire colors right (Green is always Grd.) Each part should be set and connected with different parts in particular manner Literally, a circuit is the path that permits electrical power to flow. There was nothing wrong with the switch itself. Wiring & Adjustment Instructions.

It will likely be mounted on the outside of your pressure tank. If the image of the switch I saw is correct, you will have three wires coming to it from the power cord, and there will be 2 or three wires coming from the compressor motor. It shows the components of the circuit as streamlined shapes, as well as the power and also signal links between the devices. This differs from a schematic representation, where the plan of the components’ interconnections on the diagram usually does not represent the components’ physical locations in the finished tool. A pictorial diagram would show more information of the physical appearance, whereas a wiring diagram uses an extra symbolic notation to emphasize interconnections over physical look. This site also provides information about simple air compressor diagnostics through to more complex air compressor fixes. Resistance: Measured in Ohms (R or O), resistance specifies how conveniently electrons can move with a material. I’m not an expert, but this is pretty basic stuff…Hope this helps. The Pressure Sw. has 4 screws ....use only 2 of them (the 2 on the right OR the 2 on the left. The red wire from the 3 phase is only connected to the motor. We used a pressure switch by Square D part number 9013 FHG12MIX. On the other side of the switch the terminals may be marked “load” or “motor”, something to indicate that those are for the compressor motor.
