-
low fuel pump pressure occurs in the two wings (that is gravity fuel supply is in operation with the crossfeed valve open)
-
the surge-tank overflow sensor becomes 'wet'
-
the wing tank fuel-contents decreases to 280 kg (620 lb).
**ON A/C 301-399,
The FLSCU1 or FLSCU2 sends a signal to close the related FRV (through the FADEC) if one of these conditions occur:
-the fuel temperature sensor in the wing tank sends a high fuel temperature signal (52.5 deg.C (126.50 deg.F) approximately)
-
low fuel pump pressure occurs in a wing (Ref. 28-21-00) (that is gravity fuel supply is in operation with the crossfeed valve closed)
-
low fuel pump pressure occurs in the two wings (that is gravity fuel supply is in operation with the crossfeed valve open)
-
the surge-tank overflow sensor becomes 'wet'
-
the wing tank fuel-contents decreases to 280 kg (620 lb).
**ON A/C ALL
The FADEC closes its related FRV if the IDG oil temperature is not between certain limits (Ref. 73-20-00).
