Unit of competency
Modification History
Release 1. This is the first release of this unit of competency in the UEE Electrotechnology Training Package. |
Application
This unit involves the skills and knowledge required to diagnose and rectify faults in digital controls systems. It includes preparing, diagnosing and rectifying faults. It also includes completing and reporting fault diagnosis, interpreting diagrams and technical data, applying knowledge of digital systems to logical fault-finding processes, implementing fault rectification, and safety and functional testing. No licensing, legislative or certification requirements apply to this unit at the time of publication. |
