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.
￭ 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.
￭ 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.
￭ Acceptance test procedure
After wiring the Safe torque off function, validate its operation as follows.
Note:
If the drive is equipped with safety Q950, +Q951, +Q952, +Q957, +Q963, +Q964,
+Q978 or +Q979, do the procedure shown in the documentation of the option.
Note:
If the drive is equipped with safety Q972 or +Q973, do the procedure shown in the
FSO module documentation.
Note:
All inverter modules of the inverter unit must be powered and connected to the STO circuit
during the acceptance test.
Action
WARNING!
Follow the safety instructions given in Safety instructions . Ignoring the instructions can cause
physical injury or death, or damage to the equipment.
Ensure that the drive can be run and stopped freely during start-up.
Stop the drive (if running), switch the input power off and isolate the drive from the power line by a
disconnector.
Check the Safe torque off circuit connections against the wiring diagram.
