In the given conditions the materials that are available in the laboratory are allowed to be used. Also, before conducting the experiment it needs to be designed and simulated in the FluidSim and it should be checked by the instructor. The operation of the experiment 2.1. and 2.2. it consists of the selector switch and it’s push buttons. The selector will determine what specific cylinder will operate in a specific instance. For the design experiment 2.1, Three types of workpiece are used, blue, black, and silver. It is determined using Optical Proximity Sensor, Inductive Sensor, and Capacitive Sensor. A 5/2-way solenoid impulse valve were used in the problem. The circuit design will only operate when the workpiece that is placed is blue and silver. The push button was used in order for the sensor to detect if it’s blue or silver thus making the cylinder extend. For the design experiment 2.2, The push button and the selector are the control bulk of the material mixing system. The selector switch will select the proper silo for a specific operation, then pressing the push button opens the experiment and 2 indication lamps are added to indicate what cylinder is in operations in a given instance. Then the push button was used to retract the cylinder when the other cylinder reaches its maximum length when extended. For the design experiment 2.3, The sequence of the design experiment is A+A-B+B-. Twi 5/2-way solenoid valve 4 relays and 1 timer relays were used in the problem. When the B+ actuates after 3 seconds due to the offset timer the cylinder will retract. One push button is used to continue the cycle of operation of the experiment while the other one is to stop the cycle of operation of it. IV. D ESIGN AND I MPLEMENTATION In the design experiment 2.1, the group was assigned to design a circuit that will consists of optical, inductive and capacitive proximity sensor which will actuate a double acting cylinder when a push button is pressed and if detects a workpiece that is metal and a blue plastic. The group chose to have a design with the provision that the valve used is a 5/2- way solenoid impulse valve. The group decided to put a normally open push button with detent in order to isolate the 24V source to the circuit and satisfy the required conditions. The push button is connected in the inductive, optical, and capacitive proximity sensors. The sensors are then latched to relays and each sensor has a corresponding relay. With the use of logic and boolean algebra, the group have figured out the connections of the relays. Workpiece Optical Inductive Capacitive Metal 1 1 1 Blue 1 0 1
