Question:

How can the piston speed of cylinder 1A be greater during retraction than it is in extension for the control system shown below?

One Answer is correct

• By installation of a quick exhaust valve between valve 1V1 and 1V2
• By installation of a silencer in valve 1V1
• By installation of a flow control valve instead of the one-way flow control

valve 1V3

• By installation of an air reservoir between valve 1V3 and cylinder 1A
• By installation of a quick exhaust valve instead of the one-way flow control

valve 1V2

Answer: 1 / 4

-By installation of a quick exhaust valve instead of the one-way flow control valve 1V2

Question:

Which statement about detecting the advanced or retracted end position of a piston rod, as shown below, is correct?

One Answer is correct

• The contact reeds are opened by a magnetic field.
• The field of a magnet causes the two reeds to close, allowing current to

flow.

• Reed switches have a long service life but have a long switching time.
• In contrast to proximity switches, reed switches operate independently and

without an external mechanical actuating force.

• An electrostatic field causes the two reeds to close.

Answer:

-The field of a magnet causes the two reeds to close, allowing current to flow.

Which of the following statements about the operation of the cylinders 1A and 2A shown below is correct?

One Answer is correct

• The piston rod of cylinder 1A retracts unthrottled.
• The retracting movement of cylinder 2A is throttled.
• The exhaust air is throttled when cylinder 1A retracts.
• The piston rod of cylinder 2A advances unthrottled.
• The piston rods of both cylinders advance unthrottled and retract

throttled.

Answer:
