Sensor Types
Following subchapters just use the usual abbreviations for the different thresholds (LNR, LCR, LNC and UNC,
UCR, UNR).
5.5.2.1 Voltage Sensors
The input, standby and most payload power voltages are monitored by BMC.
All sensors use a hysteresis for the event generation. For all sensors, the hysteresis is 1.5% of the nominal
sensor voltage plus ripple from the voltage regulator.
