Critical low fuel level
alarm-engine shut down. To prevent loss of engine fuel prime
from air ingestion due to loss of day tank fuel level. When day
tank fuel level reaches imminent failure point, (approximately
1” above engine suction point) separate float switch in
day tank closes, providing signal to engine for shutdown, signal
for remote annunciator, activation of alarm light on day tank
control panel. |
