418 The Safe torque off function

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 equipment 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.
