Note: The nominal filling range indication is corrected for fluid temperature effect.
It is normally green. When temperature information is unavailable, it is no longer
corrected and the indication becomes white.
(2) Reservoir LO AIR PRESS
It is amber, and an associated caution appears on the ECAM, if the air pressure for the
indicated reservoir drops below normal.
(3) Reservoir OVHT
It is amber, and an associated caution appears on the ECAM, if the temperature of the
returning hydraulic fluid, at the inlet to its reservoir, is above normal.
(4) FIRE SHUTOFF VALVE
Crossline - Amber : The valve is fully closed.
In line - Green : The valve is partially closed.
(5) ENG PUMPS control and low pressure indication
In line - Green : The designated PUMP's pushbutton is on, and hydraulic pressure is
normal.
Crossline - Amber : The designated PUMP's pushbutton is off.
"LO" - Amber : The designated PUMP's pushbutton is on, and hydraulic pressure is
low.
(6) PUMP
It is white, and becomes amber when the corresponding engine’s N3 is below idle.
(7) ELEC
It is normally white. It becomes amber if the associated power supply fails, or if the pump is
commanded on and does not provide normal pressure.
(8) ELEC PUMP control
