We have three push buttons-PB1, PB2, and PB3-to control the simple pneumatic circuit shown below. PB1 is used to unlock access to the solenoids. PB2 is used to energize solenoid A, therefore extending cylinder A. PB3 is used to extend cylinder B by energizing solenoid B. In other words, PB1 and PB2 are required to operate Cyl A, and PB1 and PB3 are required for Cyl B. However, we desire that only one cylinder is able to move at a time, so if all three buttons are pushed, nothing should happen. Complete the ladder diagram that would control this system.
