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.
