1EFF : 401-499, 1 32-43-51Page 413 1 1 Aug 01/05 1 1 1CES 1 ALTERNATE BRAKING WITHOUT ANTI SKID - DESCRIPTION AND OPERATION
_______________________________________________________________
1. General
_______ (Ref. Fig. 001) The ALTN/OFF mode is different from the mode identified above in that there is no anti skid regulation. The anti skid regulation can be disconnected:
-either electrically (A/SKID NOSE WHEEL switch in the OFF position or power
supply failure), - or hydraulically if the brake Yellow-pressure accumulator only supplies. the brakes (then the A/SKID NOSE WHEEL switch can be in any position). Hydraulic changes between the Yellow high-pressure system and the accumulator are automatic and reversible. The brake Yellow-pressure triple-indicator shows the pressure of the accumulator. The Yellow electric pump fills the accumulator. The accumulator can supply at least seven full brake applications. This braking mode uses the second set of pistons in the brake units.

A. Brake Yellow-Pressure Accumulator and Brake Yellow Pressure Relief Valve
(1) Accumulators (Ref. Fig. 006, 007) The accumulator is of the bladder type filled with nitrogen. Filling pressure.:
-114 bars at 60 deg.C (1653 psi at 140 deg.F),
-100 bars at 20 deg.C (1450 psi at 68 deg.F),

-86 bars at - 20 deg.C (1287 psi at -4 deg.F).
Volume of fluid given : 2700 cubic centimeter.
This accumulator is used only for braking. It is pressurized by
either the Yellow hydraulic system or an electrical pump.
Check valves isolate the supply lines.
A pressure transmitter is installed in the common supply line. It
transmits data on the hydraulic fluid pressure to the third input of
the brake Yellow-pressure triple-indicator.
(Ref. Fig. 008)
The brake Yellow-pressure accumulator supplies the system that a
thermal pressure-relief valve protects. This pressure relief valve
limits the pressure to 237 bars (3436 psi) if a thermal expansion
occurs, and is also used for manual pressure release.
