Knowledge 1. True of False Controllers are usually placed in automatic mode during start up of the process or when process problems are encountered Match the following comments to the type of mode found in controllers: 2. Controller responds to the rate at which the variable changes Controller responds to an increasing input with a decreasing output Controller responds to reset the measurement back to the setpoint Controller responds to an increasing input with an increasing output Controller takes the full range of input to drive the output a. Direct b. Reverse c. Proportional d. Integral e. Derivative 3. True of False A bumpless transfer is achieved if the controller mode is changed from man- 4. True of False When switching the Foxboro Model 43 controller from manual control to ual to automatic, or vice versa, without the controller generating a change in output, automatic control, the auto/manual switch should be flipped first and then the regulator knob turned 5. True of False When switching the Foxboro Model 43 controller from automatic control to manual control, the regulator knob should be slowly moved so the indicator ball is within the central portion of the tube and then the auto/manual switch flipped.

Solution

There are too many questions, you can divide it into two different questions. However I\'m going to answer the ones that appear in the first page.

1) False.

If a problem is encountered, the controller is set to manual mode because it means a person controlling what the output signal is.

2)

First phrase: a) direct

Second phrase: e) Derivative

Third phrase: b) Reverse

Fourth  phrase: c) Proportional

Fifth  phrase: d) Integral

3) True.

Bumpless transfer allows the process to be changed from auto to manual without upsetting the process.

4) and 5) needs the Foxboro model 43 manual to be answered.
