This unit describes the skills required to conduct fault finding and repairs to the simulator power distribution and control systems. This includes analysing fault reports, identifying and rectifying faults, conducting functional tests and the documentation and certification processes. In the context of this unit, simulator systems are used to replicate land, air, sea and undersea systems to facilitate training and development.Power distribution systems may but is not limited to include power distribution software interfaces, programmable logic controllers, uninterruptible power supplies and control systems, power distribution cabinets/units, circuit breakers, emergency power/communication systems, emergency stop circuits and fire protection systems.Simulator control systems include DC low voltage supplies, DC high voltage supplies, AC low voltage supplies (less than 600VAC), uninterrupted power supplies and control systems, power distribution cabinets/units, hydraulic systems and electric systems.The skills and knowledge described in this unit must be applied within the legislative, regulatory and policy environment in which they are carried out. Organisational policies and procedures must be consulted and adhered to.Those undertaking this unit would work independently, or as part of a team, with minimal supervision, while performing complex tasks, including complex problem solving, in a limited range of contexts. They would use discretion and judgement and take responsibility for the quality of their outputs.No licensing, legislative or certification requirements apply to this unit at the time of publication.
