Application

This unit of competency defines the skills and knowledge required to test, diagnose and fault find electronic control systems associated with mobile and stationary plant and equipment.

It applies to whole of equipment diagnosis and rectification and complements diagnostic and rectification skills contained in individual system units of competency.

Where electronic systems associated with communication between the mobile or stationary plant and external communication sources such as those used for remote guidance or monitoring unit MEM27018 Test, diagnose and rectify mobile and stationary plant external monitoring and control systems should also be selected.

Where the repair of electronic circuitry associated with these systems. is required unit MEM18056 Diagnose and repair analog equipment and components and unit MEM18057 Maintain/service analog/digital electronic equipment, should also be selected as appropriate.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

What You'll Learn

Assessment Requirements

Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria on at least two (2) occasions and include:

following work instructions, standard operating procedures (SOPs) and safe work practices

identifying and interpreting specifications, manufacture/technical manuals and other applicable reference documents to diagnose and maintain electronic controlling systems on mobile plant

identifying applicable control unit and using fault codes correctly to access fault codes with indicators, meters or diagnostic tooling then clearing codes from memory and verifying using applicable procedures and manuals

tracing the root cause of faults

identifying and applying procedures to safeguard electronic components and systems when diagnosing and maintaining typical mobile electronic circuits

locating, identifying and testing applicable input and output components

repairing/replacing components and selecting replacement parts using manufacturer specifications and data

adjusting mechanical clearances and measured electrical and resistance values using appropriate tools and techniques

obtaining security codes using correct protocol from manufacturer, plant/equipment identification and using computer and relevant computer applications to download, enter and verify new specifications in accordance with manufacturer procedures.

Knowledge Evidence

Evidence required to demonstrate the required knowledge for this unit must be relevant to and satisfy the requirements of the elements and performance criteria and include knowledge of:

safe work practices and procedures and use of personal protective equipment (PPE)

applicable fault codes and their meanings and procedures to clear fault codes and verify clearance

sources of potential damage to typical mobile plant electronic systems when performing maintenance and diagnostic work and techniques and procedures to safeguard against damage

correct troubleshooting procedures, including identifying root causes of faults, including faults related to:

design

manufacturing

operator error (e.g. overload and over speed)

environment (e.g. contamination, interference and hazards)

previous service or maintenance error

procedures for:

removal and replacement of faulty components and techniques and procedures

obtaining security code

downloading, entering and verifying data

various types of input components

operation and principles of transducers used in control systems

relevant testing procedures

component types, functions and locations

techniques for repairing components

operation and principles of actuators used in control system

concepts of erasable programmable read-only memory (EPROM) and microprocessors.

Assessment Conditions

Assessors must:

have vocational competency in diagnosing and maintaining electronic controlling systems on mobile plant at least to the level being assessed with relevant industry knowledge and experience

satisfy the assessor requirements in the Standards for Registered Training Organisations 2015 or its replacement and comply with the National Vocational Education and Training Regulator Act 2011, its replacement or equivalent legislation covering VET regulation in a non-referring state/territory as the case requires

Where possible assessment must occur in operational workplace situations. Where this is not possible or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment that reflects realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills

Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications

Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
