Description
This unit covers determining and recording control loop characteristics, tuning control loops and completing service records.
Notes
Elements and Performance Criteria
1. Determine control loop characteristics
- 1.1. Engineering specifications, technical information and historical process, records and trends are examined for relevant data.
- 1.2. Consultation with system operators and other relevant plant personnel is carried out, and relevant data is extracted and documented to standard operating procedures.
- 1.3. Programmed maintenance/service reports are read and relevant data noted.
- 1.4. Data is analysed and control loop characteristics are ascertained.
2. Record control loop responses
- 2.1. Using chart recorders and data loggers, control loop responses are recorded in open and closed loop mode.
- 2.2. Unit is tested for tuning using appropriate diagnostic techniques.
- 2.3. Diagnostic results are analysed against specifications.
3. Tune control loops
- 3.1. Using knowledge of control loop device characteristics, controller mode principles and adjustment methods, tuning operations are performed using correct and appropriate techniques, procedures and equipment.
- 3.2. Recording equipment used for monitoring and adjustment of control loop components during controller tuning operations is corrected and tested.
- 3.3. Step response - open loop tuning calculations are applied to achieve specified loop characteristics.
- 3.4. Closed loop tuning methods using ultimate sensitivity and systematic trials are used to achieve specified loop characteristics.
- 3.5. Correct sequence of tuning is used on multi controllers and/or multi element systems to achieve specified characteristics.
- 3.6. Control loops are tuned to optimum mode settings utilising correct and appropriate techniques, tools, test equipment and procedures.
4. Complete service reports
- 4.1. Service reports are completed to standard operating procedures.
- 4.2. Appropriate follow up procedures are adopted.
- 4.3. Process control loop is recommissioned to specifications.
RANGE STATEMENT
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Historical process
SCADA, charts, chart recorders and data loggers, equipment condition monitoring etc.
Control loop
An opened and closed loop system includes final control elements, process measuring devices, converters, controllers, process signals and the like
Test equipment
Pneumatic, analogue and digital electronic test equipment for the monitoring and adjustment of control loop tuning

EVIDENCE GUIDE
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment
A person who demonstrates competency in this unit must be able to tune control loops - multi controller or multi element systems. Competency in this unit cannot be claimed until all prerequisites have been satisfied.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts.
Context of and specific resources for assessment
This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate.
This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with tuning control loops - multi controller or multi element systems, or other units requiring the exercise of the skills and knowledge covered by this unit.
Method of assessment
Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.
