Isometric Diagram - Shows the outline of a ship, airplane, or
piece of equipment. This diagram shows the components and the cable runs between
the components. This diagram is used to locate components in a system.
Block Diagram - Shows the components in block form. Block diagrams
are used in conjunction with text material. They are used to present a general description
of a system and its functions.
Single-Line Diagram - used for essentially the same purpose
as the block diagram-to show the basic functions of a circuit.
Schematic Diagram - Shows, through graphic symbols, the electrical
connections and functions of a specific circuit arrangement. It is used to trace
the circuit without regard to the physical size, shape, or location of the component
devices or parts. a schematic diagram shows the overall operation of a system. It
is used during troubleshooting to identify possible circuit malfunction locations.
Wiring Diagram - Is a detailed diagram of each circuit installation
showing all wiring, connectors, terminal boards, and the electrical or electronic
components of the circuit. It also identifies the wire-by- wire numbers or color
coding. This diagram must be used in conjunction with a schematic diagram to troubleshoot
a system in order to find the test point for voltage and resistance checks.
Terminal Diagram - Is used in connecting wiring to terminal
boards, relays, switches, and other
components of a circuit.
Safety - All individuals are responsible for understanding and
complying with safety standards and regulations established to prevent injury to
themselves and others and damage to property and equipment.
Having safe working habits and adhering to safety precautions protects YOU and
YOUR SHIPMATES. Follow safety precautions to the letter. DO NOT TAKE CHANCES. Carelessness
could cost you your life.
