Commissioning, Operation, and Maintenance
‑84‑
The required SIL/PL level of an implemented system is verified by using the
specific safety calculator software.
● Verification program
Inovance ensures that all the required safety functions are properly verified and
confirmed.
● Never assume that the system is safe before verifying all the safety functions.
● Perform acceptance test for every safety function.
The acceptance test must be performed by using the following startup checklist at
the following stages:
■ Initial startup of the safety functions
■ After any changes related to safety functions (wiring, assembly, settings, or
other related operations)
■ After any maintenance work related to safety functions is completed
Acceptance testing must include the following steps at least:
1. Develop an acceptance test plan.
2. Test whether all the entrusted functions can operate properly.
3. Test whether all the inputs in use can operate properly.
4. Test whether all the outputs in use can operate properly.
5. Record all the executed acceptance tests.
6. Ask the testers to sign and archive the acceptance test report for further
reference.
● Acceptance test report
You must store the signed acceptance test report in the log of the equipment.
According to relevant standards, the report must contain the following items:
■ Safety program description (including one diagram)
■ Description and revision of safety components used in the safety program
■ List of all the safety functions used in the safety program
■ List of all safety‑related parameters and their values (list of all parameters not
related to safety functions if STO is enabled on the drive)
■ Documentation of startup activities, fault reports, and fault solutions
■ Confirmation of the test result, checksum, test date, and tester for each safety
function
● Safety function verification
