 Validation of the safety functions
You must do an acceptance test (validation) to validate the correct operation of safety 
functions.
Validation procedure
You must do the acceptance test using the checklist given in sections Start-up and 
acceptance test:
• at initial start-up of the safety function
• after any changes related to the safety function (wiring, components, safety function 
related parameter settings etc.)
• after any maintenance action related to the safety function.
The acceptance test must include at least the following steps:
• having an acceptance test plan
• testing all commissioned functions for proper operation
• documenting all acceptance tests
• signing and storing the acceptance test report for further reference.
Acceptance test reports
You must store the signed acceptance test reports in the logbook of the machine and in 
the explosion protection document under the scope of the ATEX User Directive 1999/92/
EC. The report must include, as required by the referred standards:
• a description of the safety application (including a figure)
• a description and revisions of safety components that are used in the safety 
application
• a list of all safety functions that are used in the safety application
• a list of all safety related parameters and their values
• documentation of start-up activities, references to failure reports and resolution of 
failures
• the test results for each safety function, checksums, date of the tests and confirmation 
by the test personnel.
You must store any new acceptance test reports performed due to changes or 
maintenance in the logbook of the machine and in the explosion protection document 
under the scope of the ATEX User Directive 1999/92/EC.
Competence
The acceptance test of the safety function must be carried out by a competent person with 
expertise and knowledge of the safety function as well as functional safety, as required by 
IEC 61508-1 clause 6, and ATEX/Ex regulations. The test procedures and report must be 
documented and signed by this person.
 Ambient conditions
For the environmental limits for the safety functions and the drive, refer to the hardware 
manual.
