This unit of competency covers the skills and knowledge required to use an item of equipment which is operated with limited application of knowledge. This unit of competency applies to all persons who have the responsibility for using equipment where they are not required to have any significant understanding of the equipment or the process. Where greater levels of understanding and interaction are required, then the appropriate MSMOPS2# series operations unit of competency should be used. In a typical situation the operator may be using, for example, a packaged chilled water refrigeration unit to supply chilled water to the plant. The operator uses simple controls and responds to fault alarms built into the equipment. Even though the equipment may be very sophisticated (e.g. using high-speed compressors and computerised monitoring and control equipment) the operator interface is relatively simple. The operator is expected to simply regard this equipment as a black box - they may know what it does, but little detail on how it does it.This unit of competency has been written to apply to fluids as well as solids and may be applied wherever ‘black box’ equipment is used.This unit of competency applies to an individual working alone or as part of a team or group and working in liaison with other shift team members and the control room operator, as appropriate.No licensing, legislative or certification requirements apply to this unit at the time of publication.
