Demonstrate the principle of process
control by using everyday and
workplace examples in a group
discussion
The assessor will observe and confirm
that learners:
Use a workplace example of changing
from a manual system to an automatic
control loop
• Understand a simple control system
HOW
Group Discussions
Sketch
Case studies
Use checklists
Develop
recommendations
Job assignment
Make presentation
Complete documents
Draft a report
Complete a
test/questionnaire
1. Interpret the process control principles
(feedback loop) using a person setting the
water temperature for the shower
2. List process variables often controlled
and a typical feedback loops used for the
control
3. Cite workplace examples where accurate
measurement is important in order to
control efficiently
4. List a possible workplace example where
manual process control could be changed
to an automatic system and give reasons
for this recommendation
5. Sketch (with captions) open and closed
control loop systems
6. Compile all the documents into a
document for assessment
Commissioned by PAMSA
Topic assessment criteria

variables
• Understand the role of measurement in
process control
• Understand the difference between
manual an automatic control systems
• Are able to explain the difference
between open and closed loop control
systems assisted by sketches
