Title: Module Blueprint 6
Course: Open PRO130 Instrumentation I > Section: Module 6: CONTROL LOOPS: CONTROLLERS & FINAL CONTROL ELEMENT OVERVIEW, CONTROL VALVES & REGULATORS

Module Overview | Module Learning Objectives
Face-to Face

At this meeting we will...

Online

1. First read through any of my "The Big Picture" pages.
2. Next familiarize yourself with the discussion questions so that you can be thinking of them while you read. Note posting deadlines.
3. Then for this mod you want to read and then answer the questions as described.
4. Work on the Your Calculations Corner well before the end of the mod so that you can get feedback from me before the quiz.
5. Take the quiz when you feel like you will do well.
6. Complete assignments before the due dates-remember, the "due" date is not the "do" date.
By the end of this module, you will be able to:

Chapter 10

- Define terms associated with controllers.
- Define bumpless transfer of auto to manual and manual to auto control.
- Describe the process for switching from auto control to manual control on a local controller.
- Describe the process for switching from manual control to automatic control on a local pneumatic controller without bumping the process.
- Demonstrate various control skills.
- Given a drawing or actual local pneumatic controller, read the chart and state the high and low-range values.
- Given a simulator or actual device, identify if a control loop is in control or out of control and identify the information used to make the decision.
- Given a drawing or actual device, identify and describe the operation of various controllers.

Chapter 11

- Given a drawing or actual device, identify the main components of a control valve.
- Given a drawing or actual device, identify and describe current-to-pneumatic transducer & indications of a sticking control valve
- Define terms associated with valves and other final control elements.
- Describe operating scenarios in which fail-open, fail-closed, and fail-last positions are desirable.
- Discuss the purpose of diaphragm valve actuators and piston valve actuators.
- Compare and contrast a spring and diaphragm actuator to a cylinder actuator.
- Explain why the action of a valve actuator may not correspond with the action of the valve.
- Describe a valve positioner and explain three of its uses.
- Explain the function of each of the three gauges located on a pneumatic valve positioner.
- Given a pressure indication for each of the three gauges on a valve positioner, predict what the control valve movement will be.
- Describe two ways a controller’s output signal can be reversed at the valve so the valve’s action is opposite of the controller output signal.
- Describe a control scheme that utilizes reversing a controller’s output signal at the valve.
