- 1.3 Identify work health and safety (WHS) and regulatory requirements with particular emphasis on automation safety, codes of practice, standards, risk management and organisational procedures
- 1.4 Identify stakeholders to be consulted on investigation task
- 1.5 Investigate software and software techniques required for basic analysis and graphics required for controller investigation task
- 1.6 Ensure appropriate support, including licensed electrical, technical and professional assistance is available
2 Review functions and features needed in controller application
- 2.1 Use analytical and graphical software, as required, to review controller application and function
- 2.2 Validate software results
- 2.3 Undertake instrument readings, as required
3 Program controllers and SCADA applications for required functions
- 3.1 Program controller as required for required sequencing and actuations for applications

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 apply controller principles to ensure safe practice, assist with systems development, component selection and maintenance and broadly evaluate electrical, electronic and controller features and functions.
This includes working individually and as part of a team and recognising and complying with normal control procedures on engineering projects.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
Assessors must be satisfied that the candidate can competently and consistently:
identify and apply WHS, regulatory and risk management procedures
review dangers and effects of electricity on humans
identify effects and dangers of electricity, automated systems and specialist requirements, such as licensing related to technical work
confirm personal functions and responsibilities and that of team and support functional group
review sustainability implications, functions and features of controllers and related devices, machines and systems
assess and apply basic electrical and electronic control principles, controller programming principles and techniques to simple machine control functions
ensure safe electrical working practice
ensure clear and logical process of analysis
report and document results.
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 then a simulated working environment 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.
Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.
Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.
Method of assessment
Assessment must satisfy the endorsed Assessment Guidelines of the MEM05 Metal and Engineering Training Package.
Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge.
Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure correct interpretation and application.
Assessment may be applied under project-related conditions (real or simulated) and require evidence of process.
Assessment must confirm a reasonable inference that competency is not only able to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.
Assessment may be in conjunction with assessment of other units of competency where required.
Guidance information for assessment
Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.
