hazardous area, power, earthing and EMC conditions. In many cases, there will
not be a single installation environment. Elements of the system may be
installed in differing locations; in these cases, it is important to know the
environment for each location.
System Integration
The system integration stage shall integrate the application programs with the
AADvance controller. Where multiple systems are used to meet an overall
requirement, it is recommended that each sub-system undergoes application
program and target system integration and testing before commencing overall
system integration. To meet the requirements of the intended safety
requirements class, the system integration shall result in full compliance of the
software and hardware with the functional safety requirements.
System Commissioning
The commissioning stage is to prove the system installation and verify its
correct 'end-to-end' functionality, including the connection between the
AADvance controller and the requisite sensors and final elements. It is likely
that groups of functions are commissioned in stages rather than the system as a
whole, for example accommodation area functions before production
functions. It is important to define the commissioning sequence and the
measures to be taken to ensure safe operation during such periods of partial
commissioning. These measures shall be system specific and shall be defined
clearly before starting any commissioning. It is also important to define that
any temporary measures implemented for test purposes, or to allow partial
commissioning, are removed before the system, as a whole, goes live.
Records shall be maintained throughout the commissioning process. These
records shall include evidence of the tests completed, any problem reports and
the resolution of problems.
Safety System Validation
Safety system validation shall test the integrated system to ensure compliance
with the safety requirements specification at the intended safety requirements
class. The validation activities should include those necessary to prove that the
system implements the safety actions during normal start-up and shutdown
and under abnormal fault modes.
WARNING: You must use installation and commissioning procedures that
comply with applicable standards of the country of installation. The
applicable standards can include, for example, IEC 61511, NFPA 72 and ISA
84.00.01, depending on the location.
