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. 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 Volume 2, Part 1. |
