N, rope (61) stops, rope (64) draws, does light sensor (344) expose? / Y, does light sensor (383) expose? Y, rope (64) stop rope (61) and draw, does light sensor (344) expose? / N, it is a bit of to delay time, and returns this starting point, EP (end of program); And

Flow process 29: program begins, and two end plates drop to minimum, does switch 2K select the straight waist (R) of straight lower limb (L)? R, change [515]/L, clutch (230) divides, round pin (219,271) between inside and outside, middle bed board changes counterclockwise, is limit switch (273) depressed? bed board changeed/Y counterclockwise during N returned, round pin (219,271) greater than the outside, pin (322) stretches out, and clutch (230) closes, EP (end of program)

[515]: clutch (230) divides, and back bed board changes clockwise, is limit switch (239) depressed? N, return the back bed board change clockwise/Y after bed board (210) stop, clutch (230) closes, and rope (61,103) is stopped, rope (72,129) open certainly, rope (61,103) stops EP (end of program);
