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. 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.
Workplace health and safety (WHS) requirements:
are those prescribed under legislation, regulations, codes of practice, and workplace policies and procedures
may include:
protective clothing and equipment
use of tools and equipment
handling of material
use of fire-fighting equipment
first aid equipment
hazard control, including control of hazardous materials and toxic substances.
Faults may include:
indirect faults caused by the influence of external systems (electrical and electronic) which may or may not be faulty in their primary operations
direct faults in input sensors, output actuators, wiring harness, computer systems, calibration or adjustment specifications
component specifications, component assembly, component damage and system modifications
indirect mechanical faults
mechanical and hydraulic system faults
Tests may include:
wiring and connector integrity
operation and specification of input and output devices
controlling electronic components and computers
data interpretation and readings related to direct indirect and intermittent causes
hydraulic systems testing
electrical systems testing
mechanical systems testing
road test.
Testing equipment may include:
analogue and digital multimeters
lab oscilloscopes
scan tools
test lights and test LEDs
pulse generators
manufacturer and component supplier testing equipment
pressure gauges
Diagnostic processes may include:
analysing manufacturer and component supplier specifications, schematics and operational procedures related to mobile plant hydraulic systems
six-step troubleshooting plan
discover-investigate-fix methodology

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

Critical aspects for assessment and evidence required to demonstrate competency in this unit
The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy all of the requirements of the performance criteria and required skills and knowledge.
A person who demonstrates competency in this unit must be able to:
interpret workplace instructions and locate and apply information
apply safety requirements, including the use of personal protective equipment
identify and select appropriate diagnosis processes to be performed
complete diagnosis of complex faults on a minimum of three different mobile plant hydraulic systems with real or simulated faults
document and report outcomes and required actions of diagnosis of complex faults in mobile plant hydraulic systems.
Context of, and specific resources for assessment
Competency is to be assessed in the workplace or a simulated workplace environment that accurately reflects performance in a real workplace setting.
Assessment is to occur:
using standard workplace practices and procedures
following safety requirements
applying environmental constraints.
Assessment is to comply with relevant:
regulatory requirements
Australian standards
industry codes of practice.
The following resources must be made available for the assessment of this unit:
workplace location or simulated workplace
vehicles systems with real or simulated mobile plant hydraulic system faults
tools and equipment appropriate for the diagnosis of complex faults in mobile plant hydraulic systems
technical reference information and workplace instructions.
Method of assessment
Assessment must satisfy the endorsed Assessment Guidelines of this Training Package.
Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with the application of required skills and knowledge.
Assessment methods must be by direct observation of tasks and include questioning on required skills and knowledge to ensure correct interpretation and application.
Competence in this unit may be assessed in conjunction with other units which together form part of a holistic work role.
Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate the needs of diverse clients.
Assessment processes and techniques must be culturally sensitive and appropriate to the language, literacy and numeracy capacity of the candidate and the work being performed.
