Question 1

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

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

Which of the following PLC programming languages is based on a graphical representation of relay logic circuits?

A : Ladder Diagram (LD)

B : Function Block Diagram (FBD)

C : Structured Text (ST)

D : Instruction List (IL)

Answer: A

Question 4

Which of the following places the steps of the procedure model in the correct order?

A : Procedure, unit procedure, operation, phase, action, transition.

B : Procedure, operation, unit procedure, phase, transition, action.

C : Procedure, unit procedure, operation, transition, phase, action.

D : Procedure, unit procedure, operation, phase, transition, action.

Answer: A

Question 5

What are some of the systems that are typically included in the scope of building automation?

A : HVAC (heating, ventilation and air conditioning), electrical, lighting, shading, access control, security systems

B : HVAC (heating, ventilation and air conditioning), plumbing, fire protection, elevators, escalators, parking systems

C : HVAC (heating, ventilation and air conditioning), audiovisual, communication, network, data center, backup power systems

D : All of the above
