Introduction to automation quiz

3 elements of an automated system?

• control system

• power supply

• pipe line system

• Control programming instructions

What is program of instructions in an automated system?

• process work flow

• the program defines the actions performed by an automated process

• Decision making system

• to run a machine with electric power?

Why the electric power is prefered in automated progress?

Which is not correct?

• can use to represent signal, information, data…

• readily converted to alternative energy forms

• can be stored in long-life batteries

• to run every actuators at lowest cost

Which one is not an element in a open-loop control system?

• controller

• feedback signal

• actuator

• output variable

When shoud we use the open loop control?

• Performed actions are simple

• Actuating function is reliable

• Any reaction forces opposing the actuator are small enough to have no effect on the actuation

• To ensure the process responses properly to control inputs

Why do we need safety monitoring?

• Protect human workers and equipment

• to avoid animals invasion

• because it's cheap and make the report better

• it makes the factory look more professional

What response should not be done to unsafe condition?

• stop the system with a procedure

• keep operating until end of shift and report to manager

• reducing operating speed

• taking corrective actions

What are main tasks of maintenance and repair works?

• Status monitoring

• Fairlure diagnostics

• Change the way to report

• Recommendation of repair procedure

• level 1

• level 2

• level 3

• can be in any level 1,2,3

production management system normally is at level?

• level 5

• level 4

• level 3

• level 2
