Unit and batch traceability

What traceability means here

Traceability is the ability to start from a unit in service and find what it is, how it was configured, what it was made from and how it was verified. It is also the ability to start from a material or a production batch and find every unit it went into. Invitrona approaches it as a working tool for service and investigation, not as paperwork.

Identity of a unit

Each piece of cabinet equipment, transformer or rectifier carries a serial identity on its rating plate. The identity links to:

• The order and the agreed configuration, with its revision
• Key materials and components where they are tracked
• Inspection and test records
• Dispatch, commissioning and service records

Batches for high-volume products

Power supplies and LED drivers are produced in batches. Each unit carries batch or serial identification on its label, linking it to the approved configuration and the production records for that batch. For OEM programmes, private-label products keep an internal link to the Invitrona configuration and revision.

Why it matters

When a unit is reported faulty, its identity gives the service team the configuration it was built to, the conditions it was selected for, and the results of its final inspection. When a component is found to be faulty, the batch link shows which other units may be affected. Without that link, an investigation starts from guesswork.

Keeping identity intact

The rating plate is a controlled record of the physical unit. It should not be covered, removed or replaced during installation or maintenance. Service labels are placed beside it, not over it. When reporting a fault, the details on the rating plate are the fastest way to identify the unit; the service request form asks for the product identity and serial number for this reason.

Multi-site and project records

For programmes across many sites, the same identifiers are used in site records, commissioning reports and service requests, so that a unit can be located and its history compared with others in the same programme.

How long records are useful

Electrical equipment often stays in service for many years and may change hands between owners, contractors and facility managers. Records are most useful when they can be found long after commissioning. Keeping the unit identity visible, and the handover documents with the owner's asset records, means that the configuration and history of a unit can be retrieved when it is serviced, extended or replaced.

Questions you can ask

• Where is the serial or batch identity marked, and what does it link to?
• Which components or materials are traced to the unit?
• How are units identified across the sites of a programme?

What this means for a buyer

Keep the rating plate visible and the handover documents with the equipment. When you report an issue, the unit identity lets the facts be established quickly and accurately.
