Troubleshooting and Maintenance Manual (AADvance
Controller)
 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 resultant
corrective action where applicable
Maintaining Functional Safety
Design changes will inevitably occur during the system life-cycle; to ensure that the system safety is
maintained, such changes shall be carefully managed. Procedures defining the measures for updating the
plant or system shall be defined and documented. These procedures are the responsibility of the end
user, but the system integrator shall provide sufficient guidance to so that the procedures maintain the
required level of functional safety during and after the changes.
Input Module Calibration
The Operation and Maintenance Plan shall include recommendations to check the calibration of
controller input modules.
The calibration of each analogue input module should be checked every two years; the calibration of
each digital input module should be checked every five years.
Product Level Module and Firmware Updates
Special consideration shall be given to procedures for product level module and firmware updates.
Updates to the system shall include the modification requirements for application changes and
firmware changes.
The procedures shall include the need to undertake impact analysis of any such changes, and the
measures to change the system and its application programs as a result of the the modification
requirements.
Specifically, the additional requirements defined here shall be applied, as well as the requirements
defined for the following items:
