Because today, bringing the industrial PLC.. Utilization that technology . This is the key to on the production. That can react to every Manufacture physical process. And write a program that can control the measuring instrument . Utilized in industrial applications. This is demanded in manufacture today. It must be readied to move to the engineering diligence . It's now lots .
2. The structure of the system .
Projects mixer liquid is controlled by PLC consists of the power supply is separated into two parts : ALTERNATING CURRENT 110 ATOMIC NUMBER 23 paid solenoid Grand piano valves and ALTERNATING ELECTRIC CURRENT 220 V earnings pumps, motors, and P. Chelsea PLC to command the working fluid integrating all By entering the command to go the PLC physical process. Pent coating to pay when a tank hit head start. Pump mathematical function to provide liquid tank top tank top human activities to keep the liquid before adding liquid intermixture storage tank is equipped with liquid grade detective work . To obtain the fluid degree as set apart. When the liquid grade as set apart. Liquid Motors will work to tank after storage tank mixing the liqu.
2.1 power supplying tours and control valves.
Powerfulness supplying circuit control valve When Sapoana¿ the open circuit. Remembering map and powerfulness off both 220 V and 110 V electrical circuit employs a powerfulness transformer 110 V.
YARD & C takes valve circuit. Each valve will work. When it has the Holy Order from the PLC over electrical relays. The valve, each will do differently are as follows : Relay K1 will add to the valve 1 opened up to furnish liquid to tank relay K2 to order the valve 2 opened to furnish liquid to storage tank the storage tank filled up at a relay K3 to order the valve 3 spreads out to dole out liquid into storage tank from the storage tank filling two relay K4 to order the valve 4 opened to furnish liquid to tank from the tank fill three relay races K5 to order the valve 5 unfolds to fill the liquid into tank Fill the pail to pay a relay K6 to order the valve 6. Open to fill a liquid into tank top 2 of storage tank payment electrical relay K7 to order the valve 7 spreads to fill the liquid into tank top 3 of tank payment relay K8 is to order the pump function .
