Instrumentation I - Session 10

2. Session 10 – Objectives (Page 1)
1. Define terms associated with controllers:
auto/manual switch
local/remote switch
setpoint
tuning
direct acting
reverse acting
proportional band/gain
integral/reset
derivative/rate
2. Define “bumpless” transfer of auto to manual/manual to auto control.
3. Describe the process for switching from auto control to manual control on a local controller.
Instrumentation I - Session 10

3. Session 10 – Objectives (Page 2)
4. Describe the process for switching from manual control to automatic control on a local pneumatic controller without bumping the process.
5. Demonstrate various control skills, such as:
make setpoint adjustments on a local controller
operate a local controller in manual mode
make setpoint adjustments on a remote pneumatic controller
switch from manual to automatic control on a remote pneumatic controller without bumping the process.
6. Given a drawing or actual local pneumatic controller, read the chart and state the high and low range values.
7. 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.

4. Session 10 – Objectives (Page 3)
8. Given a drawing or actual device, identify and describe the operation of the following:
local controller
remote controller
split range controller
cascade/remote setpoint (RSP) controller
ratio controller
9. Provide an application requiring the following devices:
10. Describe the role of the final control element as it relates to the process and the control loop.
Instrumentation I - Session 10

5. Session 10 – Objectives (Page 4)
11. Describe three types of final control elements and provide an application for each type:
control valve – manipulates a process flow (liquid/gas) in response to a control signal
damper/louver – manipulates an air flow to control draft setting or temperature setting
motor – starts or stops in response to a control signal.
12. Given a drawing or actual instrument, identify and describe the operation of the following:
louver/damper final control element
variable speed motor used as a final control element
instrument air regulator
