Start-up and use
Contents of this chapter
This chapter contains the start-up and acceptance test procedure for the Safe torque off
function and gives instructions for its use.
Start-up and 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.
 Competence
The acceptance test of the safety function must be carried out by a competent person with
adequate expertise and knowledge of the safety function as well as functional safety, as
required by IEC 61508-1 clause 6. The test procedures and report must be documented
and signed by this person.
