Diagnose and rectify faults in d.c. motor drive systems
KHU-ELT-0346
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
