Elements and Performance Criteria

Stream: Production Plant
Field: Maintenance
Equivalencies: This unit of competence is based on unit 9.1 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
Materials may include cables, solder/flux, lubricants, cleaning solvents, contact cleaners, connectors, adhesive and sealants
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, decade box, DC I/V standard, potentiometer, hand-held communicator/programmer, frequency counter, function generator, CRO, LCR bridge, logic analyser and specialised test equipment
Fault finding and diagnostic techniques may include linear approach, half split rule, sensory detection, insulation/resistance and continuity tests
Fault indicators may include indication lamps, LEDs, 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

Critical aspects of evidence
The knowledge and application of relevant sections of: Occupational, health and safety legislation; Statutory legislation; Enterprise/site safety procedures; Enterprise/site emergency procedures
Attainment of electrical licence, where appropriate, deeming competency associated with electrical work
Preparation and planning of work
Verification techniques
