Start-up including validation 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 a validation test.
The test must be performed
1. at initial start-up of the safety function
2. after any changes related to the safety function (circuit boards, wiring,
components, settings, replacement of inverter module, etc.)
3. after any maintenance work related to the safety function
4. after a drive firmware update
5. at the proof test of the safety function.
￭
Competence
The validation 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.
￭
Validation test reports
Signed validation 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 validation tests performed due
to changes or maintenance shall be logged into the logbook.
￭
Validation test procedure
After wiring the Safe torque off function, validate its operation as follows.
Note: If a CPTC-02 or an FSPS-21 module is installed, refer to its documentation.
Action
WARNING!
Obey the safety instructions. If you ignore them, injury or death, or damage to the equip-
ment can occur.
Make sure that the motor 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 motor
should not start.
• Close the STO circuit.
• Reset any active faults. Restart the drive and check that the motor runs normally.
