2-wire, 3-wire, and 4-wire transmitters refer to the transmitters whose outputs are analog DC current signals. They have quite many differences in working principles and structures, not only limited to wiring forms of the transmitters.

The PTC (positive temperature coefficient) relay is directly connected in series with the secondary winding (start winding) and in parallel with the main winding of the motor. When AC 220V is applied to the two windings, a phase difference will be generated due to phase separation, thus forming an elliptical rotating magnetic field and generating a starting torque to drive the normal operation of the motor. After that, because the PTC relay is under a high resistance state, the starting circuit is nearly disconnected, and only the running winding drives the motor to run.

1. Main Circuit Wiring 1.1 Open the cover by squeezing the grooves on both sides of the VFD(variable frequency drive), remove the wire baffle, connect the terminals R, S, T to the power, connect the terminals U, V, W to the motor, and connect the earth wire at the ground symbol. 1.2 Connect the yellow, green and red power cables to the R, S and T in sequence.

When the current flows through the stator winding, the stator winding produces a vector magnetic field. The magnetic field will drive the rotor to rotate an angle, so that the direction of magnetic fields of the rotor is consistent with that of the stator. When the vector magnetic field of the stator rotates an angle, the rotor also rotates at an angle with this magnetic field. Every input of an electric pulse leads the motor to rotate at an angle to advance one step. The angular displacement of the output is proportional to the number of pulses input, and the speed is proportional to the pulse frequency.
