Deck 22: Installing Control Systems

Question 1

When connecting a circuit, what are some actions that can be taken to aid in the identification of all the components?

Answer 1

When making connections, wire numbers should be placed on the wire at any point of termination. This greatly aids in troubleshooting the circuit. Each component should also be labeled with a tag to identify the component.

Question 2

Figure 22-1

In the accompanying figure, two float switches are necessary in this circuit because the tank is to be ____________________.

Answer 2

pressurized

Question 3

One of the methods for installing control systems involves using a(n) ____________________ to terminate the different control components.

Answer 3

terminal strip

Question 4

The point-to-point method generally results in a saving of wire.

Question 5

Why are wiring drawings sometimes misleading?

Question 6

In the above figure, the normally open contact of float FS1 is used to prevent the ____________________ from energizing unless the tank is full of water.

Question 7

Although connecting components to a terminal strip generally involves using a greater amount of wire, it can be the less expensive method when it is necessary to ____________________ the circuit.

Question 8

Figure 22-1

In the accompanying figure, what do float switches FS1 and FS2 do?

Question 9

Components such as float switches and pressure switches will generally be located on tanks.

Question 10

In the ____________________ method, components are connected from one point to another depending on the proximity of one component to another.

Question 11

Connecting components to a terminal strip is the more expensive method when it is necessary to troubleshoot the circuit.

Question 12

In the point-to-point method, the connections made inside the MCC are shown with solid lines.

Question 13

In the accompanying figure, what happens when the water level begins to rise?

Question 14

In the accompanying figure, what happens when the water level drops sufficiently?

Question 15

When making connections, wire numbers should be placed on the wire at any point of termination.
