Service and repair electronic control and monitoring systems on land-based equipment

URN: LANLEO23
Business Sectors (Suites): Land-based Engineering Operations
Developed by: Lantra
Approved on: 2022

Overview

​

This standard covers the service and repair of electronic control and monitoring systems on land-based equipment. It includes the electrical and electronic components and systems used in the generation, processing and transmission of data for the control and monitoring of land-based equipment and its associated activities.

It also includes the fundamental skills and knowledge to enable the technician to understand the function and application of the components and systems used, the technology employed and how to verify system performance and diagnose and rectify system non-conformity to manufacturer’s specifications.

Any testing equipment used should be calibrated to manufacturer’s requirements. 

When working with machinery or equipment you should be trained and hold current certification, where required, in accordance with the relevant legislation.

When working on high voltage (hazardous voltage/HaV) electric vehicles, de-energising must be done by a person who has been trained in accordance with the manufacturer’s procedures.

This standard is for those who work in land-based engineering using their initiative in a customer-facing role. It may include mentoring a junior colleague to assist in aspects of service and repair.

Performance criteria

You must be able to:

​

  1. be aware of hazards and assess the risks associated with the activity and the location where it is to be carried out
  2. be aware of the potential environmental impact associated with the activity and ways in which this can be controlled
  3. select and wear suitable clothing and personal protective equipment (PPE)
  4. select, prepare, use, maintain and store the tools and equipment required to carry out the activity in accordance with the relevant legal requirements, manufacturer's instructions and company practices
  5. test and verify the integrity of diagnostic equipment
  6. check that the land-based equipment requiring service and repair is safe, prepared and isolated from power sources, where required
  7. take the correct precautions to prevent the escape of chemicals, gases and other substances and minimise the dangers from contamination and hazards, where required
  8. use a variety of methods to collect diagnostic information to identify defects and faults in land-based equipment’s electronic control and monitoring systems and components, including intermittent faults
  9. determine the requirements for service and repair
  10. identify and establish the availability of replacement components required for the activity
  11. service/repair and/or replace components to confirm reliable performance of the electronic control and monitoring systems
  12. retrieve/interpret/migrate stored information from electronic control and monitoring systems
  13. set parameters, calibrate, and verify the performance of electronic control and monitoring systems
  14. maintain electronic control and monitoring equipment to confirm its reliable performance
  15. recognise the characteristics of electromagnetic fields and the influence these have on associated circuits
  16. confirm that the equipment is correctly set or calibrated following service and repair
  17. use suitable testing methods to assess the performance of the reassembled system on completion of the activity and confirm that it performs to the operating specifications prior to returning the equipment to the customer
  18. recycle or sustainably dispose of the different types of waste, including hazardous and non-hazardous, caused by the activity, in accordance with the relevant legal and environmental requirements and company policies 
  19. complete records as required by the relevant legislation, warranty requirements and company procedures
