Things Covered In NVQ 2346-03 Level 3 Unit 115 Assignment

Task 1: Confirm that it is safe to begin diagnosing electrical faults.

Task 2: Notify all necessary individuals (e.g., people on-site, equipment users) before starting fault diagnosis.

Task 3: Safely isolate the electrical system before carrying out any diagnostic procedures.

Task 4: Identify and use suitable safety measures to protect yourself and others while diagnosing and fixing faults.

Task 5: Communicate clearly with key individuals (like customers or site managers) to understand the fault.

Task 6: Choose and interpret the correct documents (e.g., schematics, layout diagrams) relevant to the system in question.

Task 7: Review and communicate any possible disruption caused by the fault diagnosis and repair process to:

7.1 Team members or colleagues
7.2 Clients or end-users

Task 8: Conduct detailed inspections of electrical systems and analyze the results effectively.

Task 9: Ensure that all testing tools are appropriate for the job, functioning properly, and correctly calibrated.

Task 10: Use suitable tests, based on sound engineering judgment, to identify faults such as:

10.1 Power loss
10.2 Overloading
10.3 Short circuits
10.4 Ground faults
10.5 Incorrect phase sequencing
10.6 Loose connections or high resistance points
10.7 Equipment or component failure
10.8 Open circuits
10.9 Signal-related faults

Task 11: Apply effective fault-finding methods, which include:

11.1 Systematic problem-solving
11.2 Safe work practices

Task 13: Determine suitable actions for repair, replacement, or removal, and discuss the implications with:

13.1 Team members or technicians
13.2 Clients or customers

Task 14: Carry out repair work safely and correctly using the right tools and materials.

Task 15: Evaluate whether the new components:

15.1 Allow for future maintenance access
15.2 Meet applicable safety standards
15.3 Follow manufacturer or company guidelines

Task 16: Follow procedures to ensure electrical systems are left safe if immediate fault resolution is not possible.

Task 17: Set up and complete a final inspection and testing routine to confirm proper operation of equipment after repairs.

Task 18: Accurately document test results and key information, and report findings to:

18.1 Colleagues or coworkers
18.2 Clients or end-users
18.3 Other relevant service personnel

NVQ 2346-03 Level 3 Unit 115 Apply Fault Diagnosis and Rectification

Fault Diagnosis and Rectification is the identifying a problem and correcting it. It is an important part of maintaining the quality of a system and making sure it’s readable. Many techniques can be used for identifying a problem and rectifying it, but the choice of technique depends on the nature of a system and the type of error. Some Common techniques are:

Testing
Debugging
Tracing
Monitoring

Testing is a process of executing a system…with the intention of finding errors. There are two basic types of errors, functional and non-functional, and they can be used to identify both. Debugging is the process of identifying and correcting errors in a system. It usually starts with analyzing the system to identify the cause of an error and then rectifying it. Tracing is the process of following the flow of data to identify an error and Lastly Monitoring is the process of checking the state of a system and then recording it. All these techniques can be used to find both functional and Non-functional errors.
