Learning Outcomes and Application
|
This unit involves the skills and knowledge required to diagnose and rectify faults in systems controlling starting, speed, torque, power output, and efficient running and braking of direct current (d.c.) motor drive systems.It includes applying safe working practices; interpreting technical data; applying knowledge of d.c motors operating parameters to logical fault-finding techniques; implementing fault rectification, safety and functional testing; and reporting work activities and outcomes.The skills and knowledge described in this unit require a licence or permit to practice in the workplace where work is carried out on electrical installations which are designed to operate at voltages greater than 50 volt (V) alternating current (a.c.) or 120 V d.c. Competency development activities in this unit are subject to regulations directly related to licensing. Where a licence or permit to practice is not held, skills and knowledge described in this unit require a relevant contract of training, such as an Australian Apprenticeship. Additional and/or other conditions may apply in some jurisdictions subject to regulations related to electrical work. Practice in the workplace and during training is also subject to work health and safety (WHS)/occupational health and safety (OHS) regulations.Permits may also be required for some work environments such as confined spaces, working aloft, near live electrical apparatus and site rehabilitationNo other licensing, legislative or certification requirements apply to this unit at the time of publication. |
Duration and Setting
|
X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting. Assessors must hold credentials specified within the Standards for Registered Training Organisations current at the time of assessment. Assessment must satisfy the Principles of Assessment and Rules of Evidence and all regulatory requirements included within the Standards for Registered Training Organisations current at the time of assessment. Assessment must occur in suitable workplace operational situations where it is appropriate to do so; where this is not appropriate, assessment must occur in simulated suitable workplace operational situations that replicate workplace conditions. 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. Resources for assessment must include access to: a range of relevant exercises, case studies and/or simulations relevant and appropriate materials, tools, facilities, equipment currently used in industry resources that reflect current industry practices in relation to diagnosing and rectifying faults in d.c. motor drive systems applicable documentation, including workplace procedures, equipment specifications, regulations, codes of practice and operation manuals. | |
