Question 1

What are the two main factors that affect the maximum number of devices that can be powered from the FOUNDATION Fieldbus H1 segment?

A : The length of the cable and the voltage drop along the cable

B : The current consumption of each device and the total current available on the segment

C : The data rate of the communication and the bandwidth of the cable

D : The type of physical media and the type of explosion protection

Answer: A

Question 2

A device failure goes undetected by internal diagnostics; it does not directly impact safety but it does impact the ability to detect a future fault in a diagnostic circuit. In a failure rate database, this event would be classified as:

A : safe failure, since it does not increase the risk of a hazardous event and can be corrected during routine maintenance.

B : A dangerous failure, since it reduces the availability and reliability of the device and increases the probability of a hazardous event.

C : A latent failure, since it is not detected by the device or the user and remains hidden until it causes a hazardous event.

D : A nuisance failure, since it does not affect the safety or availability of the device but may cause annoyance or inconvenience to the user.

Answer: A

Question 3

Cavitation is typically NOT caused by which of the following?

A : High flow velocity through the valve

B : Low pressure drop across the valve

C : High pressure recovery downstream of the valve

D : Low vapor pressure of the liquid

Answer: A

Question 4

Which of the following would be MOST likely to provide velocity control feedback for a hydraulic cylinder?

A : linear variable differential transformer (LVDT)

B : A pressure relief valve

C : A variable speed prime mover

D : A programmable valve

Answer: A

Question 5

Cavitation is typically NOT caused by which of the following?

A : High flow velocity through the valve

B : Low pressure drop across the valve

C : High pressure recovery downstream of the valve

D : Low vapor pressure of the liquid

Answer: A
