Sensor Alert Default Values

Until the card is fully characterized in a reference system environment, system integrators can
use values to set up sensor alarms.

It is proposed to use a smart sensor algorithm that collects data from the sensors, verifies
readings and calculates history, acts quickly on critical levels, and still does not overload the low
bandwidth of the interface. It should be noted that these types of sensors are not useful for
transient alarms. For example short voltage dips or current peaks. A three-level approach to
sensor alarms seems appropriate with the following strategy:

Minor: Readings in this range should be tracked (response time: minutes)

Major: Actions to reduce load should be taken/requested (response time: less than a
minute)

Critical: Emergency shutdown/store event to NVRAM (response time: few seconds)

Following are the values to set up sensor alarms:
