Safety Manual (AADvance Controller)
System Installation Environment
The installation environment is a potential source of common cause
failure, therefore it is vital that compatibility of the equipment with the
environment is known. The environment for these purposes includes the
prevailing climatic, 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.
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, NFPA72 and
ISA 84.00.01,
depending on the 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.
