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 L536, +L537, +Q950, +Q951, +Q952,
+Q957, +Q963, +Q964, +Q978 or +Q979, do the procedure shown in the documentation
of the option.
Action
WARNING!
Obey the safety instructions. If you ignore them, injury or death, or damage to the equipment
can occur.
Make sure 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 using a
disconnector.
Check the STO circuit connections against the wiring diagram.
Close the disconnector and switch the power on.
Test the operation of the STO function when the motor is stopped.
• Give a stop command for the drive (if running) and wait until the motor shaft is at a standstill.
Make sure that the drive operates as follows:
• Open the STO circuit. The drive generates an indication if one is defined for the 'stopped' state in
parameter
31.22
(see the firmware manual).
• Give a start command to verify that the STO function blocks the drive's operation. The drive generates
a warning. The motor should not start.
• Close the STO circuit.
• Reset any active faults. Restart the drive and check that the motor runs normally.
