Types of wiring diagrams there are three basic types of wiring diagrams used in the hvac r industrytoday.

Hvac ladder diagram symbols. No more hard wired logic but memory locations instead. Most ladder diagrams show the following basic components. Ladder logic was designed to have the same look and feel as electrical ladder diagrams but with ladder logic the physical contacts and coils are replaced with memory bits. Let s take a look.

Electrical ladder drawings a standard set of symbols are used to represent devices. Prepare yourself to learn a new language. Diagrams are discussed extensively in fundamentals of hvac r in units 31 electrical components and wiring diagrams 32 controls and 33 control circuits and diagrams. Most hvac units have both types of.

For this program the relay logic s ladder diagram is duplicated with ladder logic. There is usually a legend on the side of the diagram to tell you for example that cc means compressor contactor efr means evaporator fan relay and hr means heating relay see figure 13 3. Since ladder logic is a graphical programming language the plc programs written in ladder logic are a combination of ladder logic symbols. The first and most common is the ladder diagram so called because it looks like the symbols that are used to represent the components in the system have been placed on the rungs of a.

Symbols are used to represent the de vices. There are some great exercises in myhvaclab to help students learn electrical diagrams including an interactive electrical symbol recognition activity and a virtual wiring. The ladder diagram gets its name from the fact that it looks like a ladder and each path the current takes through the apparatus looks like a rung on a ladder. Where the power supply is what path the power takes the load component the switch component and a legend for the symbols used in the diagram.

The language of automation. But those standards are quite expensive if you are just looking for the symbols used in ladder diagrams. Usually the electrical wiring diagram of any hvac equipment can be acquired from the manufacturer of this equipment who provides the electrical wiring diagram in the user s manual. Symbols and abbreviations used in the schematic mean.

Hvac ductwork symbols the following hvac ductwork symbols show the different ductworks and junctions such as straight duct miter bend miter bend 3 way junction y junction and transition. Take a look at the thermostat in figure 13 3. International society of automation isa formerly the instrument society of america adopted created the symbol convention. The y junction generally has 2 arms of equal size.

It is called ladder because the symbols that are used to represent the components in the system have been placed on the rungs of a ladder.
