Diagnose and repair faults on Tram vehicle assets, components, equipment and systems

URN: UKTTE19
Business Sectors (Suites): Tram Engineering
Developed by: UK Tram
Approved on: 2021

Overview

This standard is about diagnosing and repairing faults on Tram vehicle assets, components, equipment and systems.  You will be able to use fault finding methods and techniques to locate, diagnose and repair faults that involve the following interactive technologies: mechanical, electrical, electronic, hydraulic, pneumatic, fixtures and fittings and ancillary systems.  The type and range of problems and faults could be complex and involve the interaction between two or more assets, components, equipment and systems.  Fault diagnosis could include continual and intermittent faults and be affected by factors such as environmental, ageing, human error and inherent design problems.  From the evidence gained, you will be expected to identify the fault and probable cause.  You will be able to confirm the repair activities to be undertaken and carry out these repairs within the limits of your own authority.

Your acquired underpinning knowledge will provide an understanding of your work and an informed approach when applying fault diagnosis procedures within an integrated system. You will understand the various fault diagnosis methods and techniques in use, and their application. You will know how to apply and interpret information obtained from the diagnostic aids and equipment, when carrying out the activities and identifying faults or conditions that are outside the required specification. You will know and understand the interaction of the other associated integrated technologies and will have sufficient knowledge to carry out effective fault diagnosis of the Integrated system.

You will understand the safety precautions required when undertaking fault diagnosis activities, especially when isolating the equipment and taking the necessary safeguards to protect yourself and others in the workplace.

This standard is for those who work in the Tram engineering environment at supervisor/technician level.
