Question 1

What type of recipe plant number 5 has further modified to include the actual lots of pigment and other chemicals to be used in paint batch 5445332?

A : general recipe, which is a recipe that contains the information and instructions required to produce a product family or product class.

B : A site recipe, which is a recipe that contains the information and instructions required to produce a specific product at a specific site.

C : A control recipe, which is a recipe that contains the information and instructions required to produce a specific batch of product on specific equipment.

D : None of the above.

Answer: A

Question 2

What sensor malfunction that causes values for a particular variable to be grossly out of range describes which process data?

A : Outliers

B : Noise

C : Drift

D : Bias

Answer: A

Question 3

What is the next best course of action after troubleshooting a system failure by replacing a suspected bad component with a known good component and finding that this does not correct the problem?

A : Replace another component that is related to the problem and test again

B : Consult a third person who has advanced knowledge about the system or the principles

C : Remove devices one at a time and test again

D : Insert faults into the system and observe the response

Answer: A

Question 4

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 5

What is a cost-effective method of mitigating the effects of deep voltage sags on programmable electronic devices and preventing power interruptions or shutdowns in critical industrial manufacturing processes?

A : Using a dynamic voltage restorer (DVR) to inject the required voltage to compensate for the voltage sag and maintain the load voltage

B : Using a static synchronous compensator (STATCOM) to regulate the reactive power and improve the power factor and voltage stability

C : Using a unified power quality conditioner (UPQC) to correct both voltage and current disturbances and provide a clean power supply

D : Using a superconducting magnetic energy storage (SMES) system to store and release energy quickly and efficiently

Answer: A
