Elements and Performance Criteria

1. Determine requirements
   • Pulse system component defect reports (removal tags) or customer order are correctly interpreted and matched by part and serial numbers
   • Circuitry is correctly prepared and connected to the applicable test equipment and is functionally tested or cycled through the prescribed test procedures in accordance with the maintenance documentation for evidence of serviceability or malfunction
   • Modification status is clearly established to assist in determining the overhaul requirements for the components
   • Extent of overhaul or repair is correctly identified and documented
2. Troubleshoot pulse system components
   • Available information from maintenance records and inspection and test results is used, where necessary, to assist in fault determination
   • Maintenance manual fault diagnosis guides and logic processes are used to ensure efficient and accurate troubleshooting
   • Faults are located and the causes of the faults are clearly identified and correctly recorded in maintenance documentation, where required
   • Fault rectification requirements are determined
3. Dismantle and inspect pulse system components
   • Component parts are dismantled in accordance with maintenance manuals while observing all relevant work health and safety (WHS) requirements
   • Component parts are assessed for serviceability in accordance with the relevant maintenance documentation
   • Parts requiring specialist repair are tagged and repair instructions are accurately specified
   • Parts lists are compiled and processed in accordance with standard enterprise procedures
4. Repair and/or modify pulse system components
   • Component parts are repaired or replaced in accordance with the relevant maintenance documentation
   • Modification of components or parts is undertaken, where required, by relevant manufacturers’ bulletins or procedures
5. Assemble, test and adjust pulse system components
   • Assembly of component parts is carried out in accordance with specified tolerances and the applicable maintenance documents
   • Assembled components are tested and adjusted/aligned in accordance with the applicable maintenance documentation using the appropriate test equipment
   • Required maintenance documentation and modification records are completed and processed in accordance with standard enterprise procedures

Performance Evidence

Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria under the specified conditions of assessment, and must include:

applying relevant WHS practices

using approved repair/overhaul manuals, procedures and processes relating to pulse system components

recognising the serviceability state and repair or overhaul requirements for pulse system components

applying logic processes, using test equipment and appropriate wiring diagrams and manuals to isolate component faults

performing component testing to isolate/confirm component fault and assess post-repair/overhaul serviceability

correctly aligning components listed above to operate within prescribed specifications.

It is essential that system testing and aligning procedures, cleanliness requirements and safety precautions applicable to the pulse system components being maintained are fully observed, understood and complied with. Ability to interpret inspection procedures and specifications (allowable limits) and apply them in practice across a range of inspection, testing, alignment and troubleshooting applications (including the timely involvement of supervisors or other trades) is critical.

Evidence of transferability of skills and knowledge related to testing, aligning and troubleshooting is essential. This may be demonstrated through application across a representative range of the components listed in the Assessment Conditions.
