What are the five basic components 1. A power supply
to any schematic? 2. A path for the power
3. A load or component that operates from the
power.
4. A switch or component that interrupts the
power to the load.
5. A legend or key that explains what the various
symbols and abbreviations used in the schematic
mean.
What are the three basic types of 1. The ladder diagram
wiring diagrams used in the HVACR 2. The pictorial diagram
trade? 3. The installation diagram
Describe the characteristics of a 1. Provides the most helpful information for
ladder diagram electrical troubleshooting
2.The intention of the overall schematic is to show
how the circuit functions not how it actually
looks.
, Describe the characteristics of a 1. Usually includes drawings that more closely
pictorial diagram resemble the components themselves rather than
the symbols.
2. Provides the best indication of the actual
positions of the components in the equipment or
control panel.
Describe the characteristics of an 1. Used primarily By the person installing
installation diagram equipment
2. It normally only shows what the terminal board
connections are and may or may not include any
internal wiring of the unit
3. Field wiring Generally represented as Dashed
lines.
4. Thicker lines represent line voltage
wiring(120/240 V)
5. Thin lines represent low-voltage control wiring
What is a switch? A switch is a device that interrupts power to the
load. It may be manually or automatically
activated by pressure, temperature or it may be
an electrically controlled switch
What is a load? A load is a device that consumes power and
converts it into some other form of energy
Describe the side-by-side Usually arranges motors and other power
arrangement four wire diagrams consuming components on the right side of the
diagram called the "load" side. The switches and
other controllers are placed on the left side of
the diagram called the "line"side.
Describe the up and down This type of arrangement divides the schematic in
schematic arrangement to high-voltage and low-voltage sections.
Normally the high voltage section is placed on
the top and the low voltage is placed on the
bottom of the diagram.
