The vertical lines on an elementary diagram represent:

• time intervals

• data points

• axes

• grid lines

How are internal wiring diagrams of subassemblies, furnished on separate sheets, shown on an elementary diagram?

• They are shown as a single line.

• They are not shown at all.

• They are shown in detail.

• They are shown as a block.

The order in which control devices are shown on an elementary diagram is:

• Input, Process, Output

• Output, Process, Input

• Process, Input, Output

How can you simplify a complex schematic?

• By adding more components

• By removing unnecessary components

• By making it more complex

• By ignoring it

On a schematic, control relays are usually numbered as:

• sequential numbers

• random numbers

• based on voltage rating

• based on color codes

What is the meaning of an arrow next to the symbol for a switch if the arrow points downward and has the number 12 beneath it?

• It indicates a voltage rating of 12 volts.

• It shows the switch is rated for 12 amperes.

• It signifies a 12-degree angle of operation.

• It means the switch should be installed 12 inches below the panel.

What does underlining tell you about the contacts of relays on following lines of a schematic?

• It indicates normally open contacts.

• It indicates normally closed contacts.

• It indicates a fault in the relay.

• It indicates the relay is not used.

A control-panel layout shows:

• the arrangement of controls and displays

• the color scheme of the panel

• the size of the panel

• the material used for the panel

Where is all the information necessary for ordering replacement electrical and electronic parts given?

• In the user manual

• On the manufacturer's website

• In the product packaging

• On the warranty card

What indicates the progression of operation for all the devices shown on the elementary diagram?

• The sequence of numbers

• The color coding

• The labels on the devices

• The direction of arrows
