Controller The controller is not receiving DC
power from the shelf. All Form-C relays
are de-energized to assert respective
alarms. N/A N/A x x x x x x
Very Low Float
Voltage The system DC output voltage has
reached a low voltage threshold
generally set below the BD threshold.
This alarm is used to indicate that the
battery reserve is depleting and the DC
voltage is approaching a critically low
output value. 46.0V
