1.6 MONITORING
In order to establish that the safety objectives have been met through the lifetime of
the system it is important to maintain records of the faults, failures and anomalies.
This requires the maintenance of records by both the end-user and the system
integrator. The records maintained by the end-user are outside the scope of this
document; however, it is highly recommended that the following information be
included:
•
Description of the fault, failure or anomaly
•
Details of the equipment involved, including module types and serial
numbers where appropriate
•
When the fault was experienced and any circumstances leading to its
occurrence
•
Any temporary measures implemented to correct or work around the
problem
•
Description of the resolution of the problem and reference to remedial
action plans and impact analysis
Each system integrator should define the field returns, repair and defect handling
procedure. The information requirements placed on the end user because of this
procedure should be clearly documented and provided to the end user. The defect
handling procedure shall include:
•
Method of detecting product related defects and the reporting of these to
the original designers.
•
Methods for detecting systematic failure that may affect other elements of
the system or other systems, and links to the satisfactory resolution of the
issues.
•
Procedures for tracking all reported anomalies, their work around and/or
resultant corrective action where applicable.
1.7 DIAGNOSTIC ACCESS
The TMR Processor supports comprehensive diagnostic facilities. Some of these
facilities have the capability of modifying the system’s operation and are therefore
password protected, to provide access protection in addition to that afforded by
physical access to the system.
The password is defined in the security section of the system.ini file. The password
is encoded and is not readily decodable from the system.ini text file.
A default password is implemented automatically, however it is
recommended that a specific password be defined within the system.ini file.
It is important that this password be made available only to personnel
requiring access to the additional diagnostic capabilities (typically only ICS
Triplex Technology Ltd. personnel). If this password is lost, there is no capability
of accessing these functions without reconfiguring the system.
