In all of the tables in this document, both the pre-2009 NQF Level and the NQF Level is shown. In the text (purpose statements, qualification rules, etc), any references to NQF Levels are to the pre-2009 levels unless specifically stated otherwise.  

This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
Learners who demonstrate competence as described in the outcomes of this unit standard will be able to use a variety of process control techniques to control a process.

A person credited with this unit standard is able to:
  • Explain the purpose of using different process control techniques.
  • Explain the operating principles of different process control techniques.
  • Describe the operation of all process control techniques used in a process.
  • Use process control techniques to control a process.

    This will ensure that the process control of a processing operation is performed in accordance with procedures and accepted work practices. This competence will enhance the learner's employability and career options in all occupations where knowledge of advanced methods of process control in a process environment is needed. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    Description of required skills:
  • National Certificate Chemical Operations NQF Level 3 or equivalent, including communication and mathematical literacy, NQF Level 3. 

  • UNIT STANDARD RANGE 
    The range of this unit standard includes the following process controls and process control techniques:
  • Split ranges and trims.
  • Cascade control.
  • Quality analysers.
  • Ratio/mass flow controls.
  • Interlocks and logics.
  • Trips and alarms.
  • Overrides.

    The context of this unit standard includes a complete process, from the point of receiving a commodity raw material to the point of supplying a commercially saleable product.

    The level assigned to this unit standard is appropriate because the process requires a wide range of cognitive skills and offers a considerable choice of solutions. A broad knowledge base incorporating some theoretical concepts, analytical interpretation of information, informed judgement and a range of sometime innovative responses to concrete but often unfamiliar problems are employed. 

  • Specific Outcomes and Assessment Criteria: 

    SPECIFIC OUTCOME 1 
    Explain the purpose of using different process control techniques. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    The purpose of using each of the control techniques is explained in accordance with workplace procedures. 

    ASSESSMENT CRITERION 2 
    The advantages of using each of the process control techniques are explained in terms of own workplace and the processing industry. 

    ASSESSMENT CRITERION 3 
    The disadvantages of using each of the process control techniques are explained in terms of own workplace and the processing industry. 

    ASSESSMENT CRITERION 4 
    The concept of "advanced process control" (APC) is explained in terms of own workplace and the applications in the processing industry. 

    SPECIFIC OUTCOME 2 
    Explain the operating principles of different process control techniques. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    The operating principle of each of the different process control techniques is explained in accordance with workplace procedures. 

    ASSESSMENT CRITERION 2 
    Process examples are used to illustrate the operating principle of each of the different process control techniques. 

    ASSESSMENT CRITERION 3 
    Alternative process control methods are indicated for each of the process examples. 

    ASSESSMENT CRITERION 4 
    Advantages and disadvantages of using the alternative process control methods are discussed in terms of own workplace and the processing industry. 

    SPECIFIC OUTCOME 3 
    Describe the operation of all process control techniques used in a process. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    All the applications for each of the process control techniques in a process are identified in accordance with own workplace. 

    ASSESSMENT CRITERION 2 
    Freehand process and instrumentation diagrams are drawn of each of the process control techniques and their interconnection with the rest of process. 

    ASSESSMENT CRITERION 3 
    The specific purpose for each process control technique is explained in accordance with workplace procedures. 

    ASSESSMENT CRITERION 4 
    The logic used in each of the process control techniques is explained in accordance with workplace procedures. 

    SPECIFIC OUTCOME 4 
    Use process control techniques to control a process. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    Process controls are set and optimised in accordance to the requirements of the process and current process conditions. 

    ASSESSMENT CRITERION 2 
    The impact of different process control settings on the rest of the process is explained in terms of own workplace. 

    ASSESSMENT CRITERION 3 
    Process control settings are changed to compensate for both process and raw material changes. 

    ASSESSMENT CRITERION 4 
    The ability of the process controls to automatically compensate for process changes is demonstrated by using actual process examples. 

    ASSESSMENT CRITERION 5 
    The ability of these process controls to automatically compensate for raw material changes is demonstrated by using actual process examples. 


    UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS 
  • An assessor, accredited with a relevant NQF Level 4 or higher qualification, will assess the learner's competency.
  • Anyone assessing a learner or moderating the assessment of a learner against this Qualification must be registered as an Assessor with the relevant ETQA. 

  • UNIT STANDARD ESSENTIAL EMBEDDED KNOWLEDGE 
    Embedded knowledge is reflected within the assessment criteria of each specific outcome.
