5.12.8 Acceptance test and report
Acceptance test report for safety functions
To verify safety-related parameters, an acceptance test must be performed after initial
commissioning has been carried out and after the safety-related parameters have been
changed. The acceptance test must be documented in the form of a report. The acceptance
test reports are part of the machine documentation and must be archived accordingly.
The checksums (r9798 and r9898) ensure that subsequent changes to safety-related
parameters can be identified.
What must be carried out when an acceptance test is performed for safety functions?
1. Machine documentation
Document the machine, including its fail-safe functions.
– Description of the machine and overview/block diagram
– Fail-safe functions for each drive
– Description of the fail-safe equipment
An empty document is provided as an example following this section.
2. Function test
Check each individual fail-safe function. An empty document is provided as an example
following this section.
3. Complete the report
Document the commissioning period and sign the report.
– Check the parameters for fail-safe functions.
– Document the checksums.
– Provide evidence showing that the data has been backed up and archived.
– Sign the report.
An empty document is provided as an example following this section.
4. Enclosures with the report
Include records and printouts of measurements associated with the function test.
– Alarm reports
– Printouts of curve characteristics
– When required, you can create a list with all of the changed parameters of the inverter.
