Unit Descriptor

Unit descriptor	This unit covers the skills and knowledge required to identify low voltage electronic faults on textile machinery including looms and other weaving related equipment, spinning, tufting, carding, knitting, sewing and finishing equipment. It includes the repair or replacement of the faulty component or to refer the repair on to other personnel.

Application of the Unit

Application of the Unit	This unit applies to the diagnosis and rectification of low voltage electrical problems in textile manufacturing machinery. It requires a knowledge of yarns and fabrics and the ability to check samples and part or fully finished textile products against samples and specifications and to determine faults that are caused by electronic equipment such as control systems and sensors. It does not include 240 volt or higher equipment and circuits. Work covered by restricted electrical licenses will require additional training to meet license requirements. Discretion and judgement may be required, for both self and others, in planning and selecting processes, procedures or outcomes. Work may be conducted in a variety of environments, such as operational workplace activities, restricted space, hazardous, controlled or exposed conditions. The application of this unit is according to OHS practices of the enterprise and workplace practices, which may include: requirements prescribed by legislation, awards, agreements and conditions of employment standard operating procedures work instructions oral, written and visual communication quality practices, including responsibility for maintenance of own work quality and contribution to quality improvement of team or section output housekeeping tasks related to environmental protection, waste disposal, pollution control and recycling This unit requires the application of skills associated with planning and organising of resources and machinery for the required work, as well as applying skills and knowledge of machines and equipment to ensure production outcomes are met. Initiative and enterprise, and problem solving are key skills required to ensure operational efficiency of machines. This unit also requires and ability to communicate in writing and verbally with others.

Evidence Guide

The Evidence Guide provides advice on assessment and must be read in conjunction with the Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment Guidelines for the Training Package.
Critical aspects of evidence to be considered	Demonstrates skills and knowledge to: correctly interpret production specifications, schematics and manufacturer instructions set and operate textile machinery safely and correctly perform sample runs and analyse results identify and make appropriate readjustments to electronic controls and systems determine root cause of operational problems solve operational problems apply workplace health and safety policies in production operations maintain accurate records
Consistency in performance	Consistently applies skills and knowledge when: organising work completing tasks identifying improvements using workplace practices using OHS practices recording and reporting accidents and incidents assessing operational readiness of equipment used and work processes recognising and adapting to cultural differences in the workplace, including modes of behaviour and interactions completing work systematically with attention to detail without damage to goods and equipment
Resource implications	Access is required to real or appropriately simulated situations, including work areas, materials and equipment, and to information on workplace practices and OHS practices.
Context for assessment	Assessment may occur on the job or in an appropriately simulated environment.
Interdependent Assessment	This unit may be assessed independently or in combination with other relevant units.
