Course Description
This unit covers finding and repairing faults in motors and associated controls in refrigeration and air conditioning systems. It encompasses working safely, applying knowledge of motor systems and their controls, reading circuit diagrams, sketching diagrams from traced circuits, applying logical fault finding procedures, conducting repairs and completing the necessary service documentation.
National Codes, Titles, Elements and Performance Criteria
National Element Code & Title: |
UEENEEJ153A Find and rectify faults in motors and associated controls in refrigeration and air conditioning syst |
Element: |
1. Prepare to find and rectify faults. 2. Find and repair faults. 3. Completion and report fault finding and repair activities. |
Performance Criteria: |
1.1 OHS procedures for a given work area are identified, obtained and understood 1.2 OHS risk control measures and procedures in preparation for the work are followed. 1.3 The likely extent of work to be undertaken is envisaged from fault/breakdown reports and/or discussions with appropriate person(s). 1.4 Advice is sought from the work supervisor to ensure the work is coordinated effectively with others. 1.5 Sources of materials that may be required for the work are accessed in accordance with established procedures. 1.6 Tools, equipment and testing devices needed to locate faults are obtained in accordance with established procedures and checked for correct operation and safety. 2.1 OHS risk control measures and procedures for carrying out the work are followed. 2.2 The need to test or measure live is determined in strict accordance with OHS requirements and when necessary conducted within established safety procedures 2.3 Equipment is checked as being correctly isolated where necessary in strict accordance OHS requirements and procedures 2.4 Safety hazards resulting from the fault or breakdown are documented and risk control measures devised and implemented in consultation with appropriate personnel. 2.5 Fault finding is approached methodically drawing on knowledge of refrigeration and air conditioning motors and their controls using measured and calculated values of circuit/motor parameters. 2.6 Equipment is dismantled where necessary and parts stored to protect them against loss or damage 2.7 Suspected faulty motor, component or circuit is rechecked and its fault status confirmed. 2.8 Replacement parts required to rectify faults are sourced and obtained in accordance with established procedures. 2.9 Effectiveness of the repair is tested in accordance with established procedures. 2.10 Apparatus is reassembled, finally tested and prepared for return to service. 2.11 Unexpected situations are dealt with safely and with the approval of an authorised person. 2.12 Fault finding and repair activities are carried out without damage to apparatus, circuits, the surrounding environment or services and using sustainable energy practices. 3.1 OHS work completion risk control measures and procedures are followed. 3.2 Reusable, faulty or worn components are tagged and dispatched for repair to maintain adequate spares inventory. |

Academic Misconduct
Students are reminded that cheating, whether by fabrication, falsification of data, or plagiarism, is an offence subject to University disciplinary procedures. Plagiarism in oral or written presentations is the presentation of the work, idea or creation of another person, without appropriate referencing, as though it is one’s own. Plagiarism is not acceptable.
The use of another person’s work or ideas must be acknowledged. Failure to do so may result in charges of academic misconduct which carry a range of penalties including cancellation of results and exclusion from your course.
Students are responsible for ensuring that their work is kept in a secure place. It is also a disciplinary offence for students to allow their work to be plagiarized by another student.
Students should be aware of their rights and responsibilities regarding the use of copyright material. It is strongly recommended that students refer to the Guidelines for Students at the RMIT University Homepage.
