An interlock is a control or safety mechanism that prevents a machine from operating unless certain conditions are met, such as a guard being closed or a previous step being complete. In risk assessments, electrical schematics, and lockout/tagout procedures, interlocks appear as safeguards that reduce hazardous access or sequence errors, and they can be mechanical, electrical, or software-based.
Safety manuals, risk assessment reports, and PLC program descriptions bring interlock terminology into localization projects. Translators must distinguish between hardware interlocks, safety interlocks, and logic interlocks, and keep the terminology aligned with functional safety documents and on-screen alarm messages. Miswording here can affect how emergency procedures are understood by machine operators.
A common mistake is translating interlock as “blocking” or “jamming,” which suggests an unwanted stoppage rather than a protective condition. This can make operators override a safeguard because the translated label does not convey that a guard must remain closed for safe operation. Another error is using the same term for mechanical and software interlocks when the source differentiates them.
The EU Machinery Directive requires documentation in the language of the destination market. Safety-related terms must map exactly to the wording of the governing standard.
Angel Translation locks terms like this into a project terminology base before expert review begins, so the same source term resolves to the same target term across every document in a submission — and stays consistent in the next revision. See the 8-step AI + expert workflow.
