10) This relates to the competency standard unit as a whole providing the range of contexts and conditions to which the Performance Criteria apply. It allows for different work environments and situations that will affect performance. Inspection should be planned with the appropriate parties to determine access, conditions and work requirements. Systems can refer to furnace safeguard supervision system, gas turbine control system, water ingress protection system, ashing system, water treatment plant control system, conveyor systems, sootblower system, generator cooling system, generator excitation system, annunciator system and flame surveillance system, emergency shutdown systems, turbine compressor set control systems, compressor station control systems, gas engine alternator control systems, bore control systems, distributive control systems and complex fire/security systems. Materials may refer to fixings, lubricants, cleaning solvents, contact cleaners, emery paper, grease, oil, connectors, terminal blocks, lugs, solder, adhesives, insulation tape, heat shrink and sealants. Components may refer to transformers, switchboards, control panels, PLC’s, motor starters, motor operated valves, battery chargers, power supplies and annunciators. Test and measurement instruments may refer to multimeters, tong testers, insulation resistance/continuity tester, ductor tester, overload injection tester, cathode ray oscilloscope, variac, hand held programmer, logic probe and recorders. Fault finding and diagnostic techniques can refer to linear approach, half split rule, sensory detection, loop test, insulation/resistance and continuity tests. Fault indicators can refer to indication lamps LEDs, VDUs alarms and flag relays. Work may be performed with system on line. Work completion details may include plant and maintenance records, job cards, check sheets and on device labelling updates. Work site environment may be affected by nearby plant or processes, e.g. heat, noise, dust, oil, water and chemical. Isolations can refer to electrical/mechanical or other associated processes. Generic terms are used throughout this Training Package for vocational standard shall be regarded as part of the Range Statement in which competency is demonstrated. The definition of these and other terms are given in Section 2.1 Preliminary Information and Glossaries. |
