DC motor armature connected in series with resistor to start reverse braking forward and reverse circuit 2

202. The circuit is shown in Figure 3-202. The performance of this circuit is similar to Figure 3-201, except that a button is used instead of the main switch
.
    In the figure, Ri and R2 are the starting resistors; R: is the reverse braking resistor; R is the discharge resistor ; SBi is the forward button;
SBz is the reverse button; SB3 is the stop button; KMi is the forward contactor; KMz is Reversing contactor; KM3 is a reverse
braking contactor; KMs and KM7 are accelerating contactors.
