202 Safe torque off function
Start-up including acceptance test
To ensure the safe operation of a safety function, validation is required. The final
assembler of the machine must validate the function by performing an acceptance
test. The acceptance test must be performed
• at initial start-up of the safety function
• after any changes related to the safety function (circuit boards, wiring,
components, settings, etc.)
• after any maintenance work related to the safety function.

Authorized person
The acceptance test of the safety function must be carried out by an authorized
person with expertise and knowledge of the safety function. The test must be
documented and signed by the authorized person.
An authorized person is an individual with authorization from the machine builder or
end user to carry out, report and sign off the safety function validation / acceptance
testing on behalf of the machine builder or end user.

Acceptance test reports
Signed acceptance test reports must be stored in the logbook of the machine. The
report shall include documentation of start-up activities and test results, references to
failure reports and resolution of failures. Any new acceptance tests performed due to
changes or maintenance shall be logged into the logbook.
