Elements and Performance Criteria

Stream: Production Plant
Field: Maintenance
Equivalencies: This unit of competence is based on unit 9.2 of the Electrical Contractors
Industry Association Competency Standards (Instrumentation Stream)
Inspection should be planned with the appropriate parties to determine access, conditions and work requirements
Systems may include process control systems, PLCs, hydraulic control systems, turbine supervisory systems, water ingress protection system, flame surveillance systems, compressor surge control systems and fire detection/suppression systems
Wiring systems can refer to cords and cables such as flexible multi-core, thermocouple, coxial, ribbon and hook up cable, signal and data cable, ducts such as PVC and metal, trunking, condults and fittings such as PVC and metal (rigid and flexible) pipes, elbows, bends, tees, junction boxes, hose terminators, saddles, spacers, bushes, adaptors and locknuts, wire loom support, cable ties, unistrut, trays and ladder racks
Piping and tubing systems may refer to piping/tubing, piping/tubing enclosures, fittings and support systems
Components may include power supplies, relays, PLC input/output blocks, printed circuit boards, protection devices, switches, transformers, servo valves, positioners, converters, controllers, function cards and transmitters
Test and measurement instruments may include multimeter, standard gases, decade box, DC, I/V standard, potentiometer, radiation meter, hand-held communicator/programmer, frequency counter, function generator, CRO, LCR bridge, logic analyser and specialised test equipment
Fixed wiring tests can refer to polarity, loop impedance and continuity
Fixed piping and tubing tests can refer to leak and continuity
Monitoring equipment can refer to test recorder/data logger
Work may be performed with equipment 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

Critical aspects of evidence
