**ON A/C ALL
The pneumatic system has the subsequent subsystems:
-distribution (Ref. 36-10-00),
-
indicating (Ref. 36-20-00).
A.
Distribution The distribution system supplies the bleed air from the different bleed air sources to the user systems. The distribution system has the subsequent subsystems:
-
the engine bleed-air supply-system (Ref. 36-11-00),
-
the APU bleed-air supply and crossfeed system (Ref. 36-12-00),
-
the ground compressed-air supply-system (Ref 36-13-00),
-environment protection (Ref. 36-14-00).
B.
Indicating
The indicating system has the subsequent subsystems:
-pressure and temperature monitoring (Ref. 36-21-00),
-leak detection (Ref. 36-22-00).
The indicating system monitors:
-
the pressure and the temperature of the bleed air in the ducts,
-
the valve position of the different valves,
-
the overheat detection sensing-elements which are installed on or near to the ducts.

1 **ON A/C ALL
The pneumatic system gets electrical power from the DC system of the aircraft. The DC system supplies 28 V DC through the circuit breakers 2HA1, 2HA2, 3HA1 and 3HA2 to:
-
the Bleed Air Monitoring Computers,
-
the relays of the AIR COND overhead panel,
-
the FIRE overhead panel,
-
the pressure transducers.

R (Ref. Fig. 008, 009) The operation and control of the pneumatic system is usually automatic. The BMCs monitor and control the automatic operation. You can also control the system manually from the cockpit. The pushbutton and selector switches on the overhead panel 30VU control the manual function. You can monitor the operation of the pneumatic system on the BLEED page of the SD. The APU page of the SD also shows some information related to the APU bleed air. The pushbutton switches on the overhead panel 30VU have no indication when the system operates correctly. If there is a failure, the failure data are available on the ECAM Engine/Warning Display (EWD), the SD and the Centralized Fault Display System (CFDS). The pushbutton switches on the overhead panel 30VU can also show some failures. (Ref. 36-20-00).
