The power supply is shown at the top and the earth at the bottom to facilitate understanding of the current flow.
Basics 9 416 kV Pump Schematic. A circuit dia- gram merely makes use of some standardized symbols that represent various radio and electri- cal components or devices. A schematic diagram is the road map of the circuit.
Do the signals on the schematic flow and can they be followed easily. Circuit you must be able to read the schematic diagram of that circuit. Reading Schematic Diagrams Product Data 11 Across-the-Line Reversing Starters L1 Stop For.
How to Read Schematic Diagram Part 2. Basics 6 72 kV 3-Line Diagram. ELECTRONIC DIAGRAMS PRINTS AND SCHEMATICS To read and understand an electronic diagram or electronic schematic the basic symbols and conventions must be understood.
In order to get from one point to another you must be able to follow the appropriate route and understand the meanings of the various symbols found along the way. Try recognizing which sections are which and following the flow of circuit from input to output. EO 11 IDENTIFY the symbols used on engineering electronic block diagrams prints and schematics for the following components.
Just as the road map uses symbols to represent the. L2 2 F 3 Rev. Drawing of pneumatic circuit diagrams in accordance with standards Representation of motion sequences and operating statuses.
There might be a section for power input and voltage regulation or a microcontroller section or a section devoted to connectors. Variable resistor p. In addition to the screen presentation which can be made in any order the contents can be printed.
This USA Standard is one of nearly 3000 standards approved as American Stan. Furthermore the actual com-. In addition to the symbol each component on a schematic should.
A-4 HOW TO READ THE WIRING DIAGRAMS - How to Read Circuit Diagrams HOW TO READ CIRCUIT DIAGRAMS The circuit of each system from fuse or fusible link to earth is shown. Schematic diagrams are like road maps of electronic highway net-works. Schematic diagrams show the con-nections of the components in a clear easily readable format.
The first step toward learning the basic theory of this series is to understand circuit diagrams the a road maps that allow us to build or repair equipment. Understanding circuit symbols and components is another one of the basic building blocks needed to become an electrician. No doubt there are many circuit symbols left off this list but those above should have you 90 literate in schematic reading.
I start having problems when. Cially in older schematic diagrams. If an electrician misinterprets a.

A drawing of an electrical or electronic circuit is known as a circuit diagram but can also be called a schematic diagram or just schematic.
R 6 F OL. Schematic diagrams well drawn and clearly portrayed can help you to design build maintain trouble-shoot and repair electronic equipment. In general symbols should share a fair amount in common with the real-life components they model.
Basics 7 416 kV 3-Line Diagram. Basics 8 AOV Elementary Block Diagram. These drawings can help you find your way through the elements of simple circuits complex devices and massive systems.
This isnt a universal practice but its a good way to begin your analysis of the schematic. Or do they cross over and loop back to where it is a challenge to figure out. Basics 14 AOV Schematic with Block included.
