Safety Manager fault detection and response 3 Introduction The goal of fault detection and response is to detect and isolate any single fault that affects the safety of the process under control, within a time frame that is acceptable for the process. Note: There is always a diagnostic alarm available upon detection of a fault. Diagnostic Test Interval The Diagnostic Test interval (DTI) is the time in which detection and isolation of faults takes place. The DTI must be set to a value that is acceptable for the process, such as the Process Safety Time (PST). These values can be obtained from hazard analysis reports. FR state The Fault Reaction (FR) state of each IO point is the predetermined state or action the point assumes in case of faults. • For normally energized safety related applications, like ESD applications, the required predefined safe fault reaction state is de-energized or Low. • For normally de-energized safety related applications, like FGS applications, the required predefined safe fault reaction state for inputs is energized or High / Top Scale.
