![]() ![]() Just as a switch can be used in a two wire control system to manually control a load, a control device that is used to sense a change of pressure or physical location can be an automatic two wire control system. When the switch is closed voltage is transmitted to the relay type device energizing the solenoid of the motor pulling in the armature which results in the main contacts of the pilot device providing full line voltage to the load being controlled. Two wire controls can be connected not only to turn on lights but they may be connected to control motors.Ĭonfiguration 1 illustrates a switch connected to a motor starter coil which turns on a motor or resistive load not shown in control diagrams. This type of control system cannot sufficiently handle large amounts of current nor control loads that require more than one set of contacts that is required for single phase 240V 208 V or 480/277 circuit. Two wire controls are generally designed to carry small amounts of current. ![]() Two-wire control, as seen in configuration 1, consists of a control device containing one set of contacts used to facilitate the on an off operation of a pilot device. ![]() Does not requireįriends, if you like this information, please comment and share it.The basic control circuits include two wire, three wire controls, manual /automatic, sequential control, stop/start, forward reverse, and jogging circuits. Power circuit has not been depicted in the picture in the circuit to run the direct direction from the direct direction to the direct direction to the direct direction. It is shown in the circuit picture, the power circuit of both types of circuits is the same. Contactor K2 NO connection leaving his magnetic quCL Keep current and the motor is provided in the L2 L1 元 in order to run in full straight direction from the opposite direction to run the circuit once the circuit is used in the lift train Toli Crane etc. It is necessary to turn off the motor in the opposite direction in the opposite direction, without off-off Contractor K1 NC Combination Contactor does not allow K2 to be prevalent, thus when the motor began to roam in the opposite direction, then the Contactor K2's NC Connection Contactor K1 does not allow it to be called Interlocking, after offering the motor from the off-push button, the motor can be run in the opposite direction by Push Button R. The motor runs in the direct direction by providing the Face in the direct direction by providing the Face in the direct direction of Contractor K1 but also leaving his magnetic quil. This circuit is depicted in the picture given further in the Contractor K1 Push Button F. It is enough to change, based on this, two types of circuits are created ![]() to change the direction of rotating a three-face motor. We have learned that the Face Face Motors I have great importance if the face sequence is not well, then it will start roaming in the opposite direction, i.e. ![]()
