Three wire start stop circuit. Depressing the stop button breaks the circuit de energizing. It uses three contactors an overload relay one auxiliary contact block a normally open start pushbutton a normally closed stop pushbutton an on delay timer of 0 20 seconds and a power supply with a fuse. The start stop and timing circuits could alternatively be controlled using a plc. Control circuits can be divided into two major types.

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. One of the jog circuit designs is the two circuit pushbutton. The wiring diagram for a three wire control circuit with additional start and stop push buttons added to the circuit is shown at the top of this figure and the ladder diagram of just the control circuit is shown at the bottom.

I zl ii i i ii i i fo 0. A two wire control circuit can be a simple switch that makes or breaks connection to a motor figure 18 1. The circuit will operate as a normal three wire circuit if the start stop pushbuttons are used. I operation depressing the start button energizes coil m hold in contacts m and maintains the circuit after the start button is released.

A three wire control circuit uses momentary contact start stop stations and a normally open seal in contact connected in parallel with the start button to maintain voltage to the coil. Two wire control circuits and three wire control circuits. The set up for the three wire sire control circuit is different from the two wire operation because there are less components needed to operate the load. 1 j start 2 3 stop i n o.
