2. System Description
__________________
(Ref. Fig. 001A)
A. Direct Reading Pressure Gage A direct-reading pressure gage is installed on the oxygen cylinder to indicate the oxygen pressure. This gives an indication to the maintenance personnel when to fill the oxygen cylinder.
B. Filling Indicator The filling indicator is installed near the replenishing connector in the space provided between frame 13 and frame 15. The filling indicator permits to read the pressure inside the cylinder while filling: 0 -85 psig: RED 85-2000 psig: GREEN
**ON A/C 001-049, 051-099, 101-105, 151-199, 201-299, 301-302,
C. Cockpit Indications
(Ref. Fig. 002)
(1) On the lower ECAM DU, on the DOOR/OXY page, the oxygen pressure in the cylinder is indicated as follows:
(a) 0 to 27.5 bar (0 to 400 psig) in amber.
EFF : ALL
35-13-00Page 1
(c) An amber half frame appears when the oxygen pressure is lower than 1500 psig.
R **ON A/C 106-149, 303-399, 401-499,
C. Cockpit Indications
(Ref. Fig. 002)
(1) On the lower ECAM DU, on the DOOR/OXY page, the oxygen pressure in the cylinder is indicated as follows:
(a)
Less than 27.5 bar (400 psig) in amber.
(b)
From 27.5 to less than 55.2 bar (400 to less than 800 psig) pulses in green.
(c)
Equal to or more than 55.2 bar (800 psig) in green.
(d)
An amber half frame appears when the oxygen pressure is lower than 103.42 bar (1500 psig).
**ON A/C ALL
(2) If the oxygen pressure drops below the minimum operating pressure of
3.45 plus or minus 0.35 bar (50 plus or minus 5 psig), the indication REGUL LO PR is shown amber on the DOOR/OXY page.
