Explanation
Normal
When output current is between 30% and 100%, the
green lamps light in 15% increments (from bottom to
top) to indicate relative output value (This sample
display shows a value level of approximately 45% to
60% of available output current).
Overload
All green lamps light and one or two red lamps flash
once per second. Remove overload as quickly as
possible to prevent fault (fault timeouts vary
depending on overload condition).
Battery backup
During battery backup all green and all red lamps flash
once per second. As the batteries discharge, the green
lamps extinguish from bottom to top to indicate
remaining battery capacity (This sample display shows
a value level of approximately 55% to 70% of available
battery capacity).
Low battery
during battery
backup
All green lamps are off and one or two red lamps
continue to flash.
