Range Statement

This section specifies work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. Bold italicised wording, if used in the performance criteria, is detailed below.

Safety requirements must include:

work health and safety (WHS) and occupational health and safety (OHS) requirements, including procedures for identifying hazards and controlling risks associated with wearing jewellery while working around high electrical currents.


Performance Evidence

Before competency can be determined, individuals must demonstrate they can perform the following according to the standard defined in this unit’s elements, performance criteria, range of conditions and foundation skills:

diagnose complex faults in the monitoring and protection systems of two different vehicles, vessels or machinery

the above diagnosis must involve two of the following types of complex faults:

an intermittent fault

a fault that affects more than one system

a fault introduced as a result of a system repair

an indirect fault caused by the influence of external systems


Knowledge Evidence

Individuals must be able to demonstrate knowledge of:

work health and safety (WHS) and occupational health and safety (OHS) requirements relating to diagnosing complex faults in vehicle monitoring and protection systems, including procedures for identifying hazards and controlling risks associated with wearing jewellery while working around high electrical currents
