Elements and Performance Criteria

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. Add any 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.
Where reference is made to industry codes of practice, and/or Australian/international standards, the latest version must be used.
Context
This competency unit includes all common equipment used in the manufacturing industry and should be able to be applied to all equipment using fluid power control systems.
This competency applies to all work environments and sectors within the manufacturing industry. It assumes an understanding of the operation of all relevant equipment and processes but does not necessarily require them to be used personally.
Procedures
All operations are performed in accordance with procedures.
Procedures include all relevant workplace procedures, work instructions, temporary instructions, manufacturer information and relevant industry and government codes and standards.
Tools and equipment
This competency includes use of equipment and tools such as:
pumps
pressure controls
DCVs (directional control valves)
flow control actuators
accumulators
filters
heat exchangers
proportional, servo and cartridge valves.
Hazards
Typical hazards include:
high pressures (hydraulic and pneumatic)
hot surfaces
hydraulic oil spills and leakage
noise.
Problems
Respond to/rectify 'non-routine problems' means 'apply known solutions to a variety of predictable problems'.
Distinguish between causes of faults such as:
control system failure
process condition
materials
component types.
Typical process and product problems may include:
loss of flow, power
power failure
oil leaks (internal and external)
component malfunction
poor maintenance procedures
regular maintenance
shutdown
using accumulator as emergency source
motor failure effect on cycle time
pressure loss
short shots
loss of clamp pressure
oil temperature.
Variables
Key variables to be monitored include:
oil levels
temperatures
cavitation/aeration/noise
cleanliness
poor performance
safety aspects.

The Evidence Guide provides advice on assessment and must be read in conjunction with the Performance Criteria, required skills and knowledge, the Range Statement and the Assessment Guidelines for this Training Package.
Overview of assessment
A holistic approach should be taken to the assessment.
Assessors must be satisfied that the person can consistently perform the unit as a whole, as defined by the Elements, Performance Criteria and skills and knowledge.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
It is essential that competence is demonstrated in the ability to:
recognise potential situations requiring action and then in implementing appropriate action.
Consistent performance should be demonstrated. For example, look to see that:
machine reliability is high.
Assessment method and context
It is preferred that assessment takes place on industrial equipment in a work environment.
Competence in this unit may be assessed:
on a processing plant allowing for operation under all normal, and a range of abnormal, conditions
in a situation allowing the generation of evidence of the ability to recognise, anticipate and solve problems
using a suitable simulation and/or a range of case studies/scenarios
through a combination of these techniques.
In all cases it is expected that practical assessment will be combined with targeted questioning to assess the underpinning knowledge and theoretical assessment will be combined with appropriate practical/simulation or similar assessment. Assessors need to be aware of any cultural issues that may affect responses to questions.
Assessment processes and techniques must be culturally appropriate and appropriate to the oracy, language and literacy capacity of the assessee and the work being performed.
Specific resources for assessment
This section should be read in conjunction with the Range Statement for this unit of competency. Resources required include suitable access to an operating plant or equipment that allows for appropriate and realistic simulation. A bank of case studies/scenarios and questions will also be required to the extent that they form part of the assessment method. Questioning may take place either in the workplace, or in an adjacent, quiet facility such as an office or lunchroom.
Additional resources might include the provision of equipment with known faults/problems to allow for assessment of the ability to identify problems.
