Modify fluid power system operation

Assessment tool

Version 1.0
Issue Date: April 2024


Tasks undertaken are based on analysis of service / maintenance reports. Work is undertaken autonomously or in a team environment.

Using sound working knowledge and principles of fluid power systems, defective components, sub-assemblies and design faults are identified and appropriate redesign action is commissioned. This action may include replacement of components, sub-assemblies using equivalent parts lists in manufacturers' catalogues. Preparation for redesign specifications and associated drawing changes / modifications are personally undertaken or delegated to appropriate personnel and supervised.

Where the modification requires the knowledge of PLC program installation or commissioning, then Unit MEM10004B (Enter and change programmable controller operational parameters) and Unit MEM10005B (Commission programmable controller programs) should also be selected.

Band: B

Unit Weight: 8

This unit covers determining the requirements of the modification, undertaking the modification and evaluating the modified or repaired fluid power system.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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 modify fluid power system operation 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 modifying fluid power system operation 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.

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills

Look for evidence that confirms skills in:

obtaining, interpreting and analysing service/maintenance reports and system output information

planning and sequencing operations

checking and testing components/sub-assemblies for conformance to specification

confirming design faults

obtaining relevant information with respect to the modification requirements

developing an appropriate action plan to overcome system problems

undertaking modifications to fluid power systems where appropriate

delegating work to appropriate personnel where appropriate and supervising work

recording/reporting modifications to the fluid power system

checking the operation of the modified/repaired fluid power system for compliance with operational specifications

initiating and monitoring further corrective action, where applicable

confirming that desired outcomes are achieved

preparing evaluation reports on the modifications/repairs

Required knowledge

Look for evidence that confirms knowledge of:

fluid power system performance, faults history and variations from operational specification

faults attributable to poor design

defective components/sub-assemblies

appropriate test equipment and applications

techniques for verifying design faults

personnel to be consulted during the modification process

sources of information relevant to the modification requirements

the specifications pertaining to the selected modification/design option

the modification/design options available to overcome system faults

the cost and benefits associated with the available options

the most appropriate modification/design option

the procedures for undertaking the selected modification/design option

replacement components conforming to predetermined specifications from manufacturer's catalogues

the modifications to be undertaken

the requirements for recording/reporting modifications to fluid power systems

the revised operational specification of the fluid power system

the frequency of checks for compliance against operational specifications

the effectiveness and efficiency of the modifications/repairs

any variations from operational specifications

any further modifications/repairs that could improve the effectiveness and efficiency of the fluid power system

personnel to whom recommendations are to be made

the appropriate reporting requirements

hazards and control measures associated with modifying fluid power system operation, including housekeeping

safe work practices and procedures

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.

Modification

Modifications covered by this unit are changes to fluid power systems and equipment that lead to desired changes in system performance

Analysed

Interpretation and integration of data from process controls, instrumentation and condition monitoring systems and consultation with appropriate personnel

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
