If a component's status or parameter value represents a fault in some plant modes and not others, it should be alarmed only in the appropriate modes.
Additional Information:
The following is an example of mode dependent processing. The fact that a particular pump has shutdown may only have operational significance to the crew when the plant is operating in the power range. Mode dependent processing would allow this alarm message to be presented when the plant is in the power range but not when it is in other modes (e.g., hot standby). Strategies have also been described in which different alarm setpoints are in effect for some parameters depending on plant mode. When there may be mode-dependent changes in the alarm system's responses the cautions contained in Guideline 4.3.6-3 should be considered.
