Sinossi
From the logic of design to startup, operation and maintenance, this "user friendly" reference covers all aspects of wiring, relay logic, programmable logic controllers, and a host of electrical control applications and challenges you'll encounter on the job. Beginning with the basic principles of electrical logic, the author proceeds to guide the reader through each step of the design of a sequencing logic system, including developing the schematic diagram, making a bill of materials, and designing component wiring diagrams. You'll learn the fundamentals of programmable logic controllers (PLCs), including numbering systems, basic memory structure, system addressing, and the common instruction set. The easy-to-follow presentation takes you step by step through solving problems that require bailing circuits, sorting systems, and counting with relays, including encoding and decoding. The contrast between digital and analog control systems is also fully examined. Case histories complete with schematics and wiring diagrams are used to illustrate the principles covered, as well as to demonstrate specific troubleshooting techniques and experiences.
