ONE LINE OF THREE WIRE CONTROL CIRCUIT DIAGRAM
Basic control circuits:Three-Wire Control Circuits
Dec 09, 2015Three-Wire Control Circuits. Three-wire control circuits are characterized by the use of momentary contact devices such as push buttons. When push buttons control the operation of a motor, three wires are run from the push-button control station to the starter (Figure 18 – 6).
Control Wiring - 3 Wire Control - Start Stop Circuit
The most common use of 3 wire control is a Start/Stop control. See image below for an example of 3 wire control being used to pull in a contactor to start a 3 phase motor. When you press the start button and the stop button is not pressed, the 24VDC relay energizes and it pulls in the R1 contactor that feeds three phase power to the motor.

Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire control circuit and the 3-wire control circuit. The 2-wire control circuit uses maintained contact devices to control the magnetic motor starter.

control circuit shown in Figure 1–3. Notice that the stop pushbutton is in series with coil M, and that the start pushbutton is in parallel with M contacts 2–3. The entire control circuit in this example is in parallel between line 1 and line 2. These basic relationships can be found in many control circuits.

Line diagrams show circuits of the operation of the controller. Line diagrams, also called “schematic” or “elementary” diagrams, show the circuits which form the basic operation of the controller. They do not indicate the physical relationships of the various components in the controller.[PDF]

The control circuit is completed through the STOP button and also a “holding” contact (2-3) on the starter. When starter drops out, this contact opens, breaking the control circuit until the START button is pressed once again. L3 % T3 t Three Wires Three wjfes lead from the p/lot devtce to thestarter.
