To help illustrate the differences between wiring diagrams and schematics, a basic control circuit will first be explained as a schematic and then shown as a wiring diagram. READING SCHEMATIC DIAGRAMS To read a schematic diagram, a few rules must first be learned. Commit the following rules to memory: 1. Reading a schematic diagram is similar to reading a book, ft is read from left to right and from top to bottom. 2. Electrical symbols are always shown in their off or deenergized Wiring diagrams are used to represent electric circuits and serve as a valuable tool for system evaluation and troubleshooting. Just as road maps This statement is only true, however, if the operator of the vehicle knows how to read the road map and the HVAC

technician.knows how to read the wiring diagram. Consider the Wiring diagrams are made up of symbols that represent various circuit components, instead of images that mimic the actual appearance of them. We will now output device, the name or symbol for each control component such as valve Vl, temperature sensor TS1, or damper actuator DA1, set points for each adjustable device, range and span for each sensor, range for each actuator, dampers schedule listing size, type, and normal positions, valve Electrical system ladder diagrams are stepbystep graphical representations used to depict the electrical control and interlock wiring for starting and stopping motors in the controlled system. clutch coil, terminate to ground. The vehicle

chassis,.body, and all metal parts are common (ground) in 12volt, directcurrent (DC) automotive electrical systems. A separate ground wire circuit is not required unless the car has fiberglass or other nonconducting body components. An electrical symbol (Figure 102) is used to indicate a ground connection. Examples of other wiring diagram symbols are shown in Figure 103. The schematic for a factoryinstalled heater/airconditioner When there are many different circuits, they look like the rungs on a ladder. A ladder diagram is very easy to read, but it does not tell you anything about the physical locations of the devices, or their physical locations relative to each other. Also, a ladder diagram uses symbols to represent various

devices,.rather than pictorial representations of the devices. Figure 114 shows some of the symbols that are used in wiring diagrams. They will be explained later, as each is encountered in a Acclaimed for its meticulous accuracy and easytounderstand presentation, this trusted text helps readers master the electrical principles and practices they need to succeed as professional installation and service technicians.Wiring Diagram Symbols These symbols are commonly used in most wiring diagrams. Study each symbol so that you can identify it by sight (Tables 61 to 64). Terminal Codes Terminal codes are found on all wiring diagrams. To help you identify the color codes, they are listed in Table 65. Relay (show device used) Coiloperated

Lamps.Incandescent Neon Heatoperated Doublepole Limit switch N.O. (Normally open) Miscellaneous N.C. (Normally closed) Circuit protectors The textbook introduces the basic theory and operation of the motors and controls found in airconditioning, heating and refrigeration systems, then provides examples of complete systems, along with diagrams, theory of operation and Use appropriate number of single line diagram symbols 7.3 Circuit breaker, other than covered by item 7.2. The symbol in the "complete" column is for a 3 pole breaker. On a power diagram, the symbol may be used without other Identification. On a composite drawing where confusion with I he general symbol (item 25) may result, add the Identifying letters CB inside
