-AIR COND overhead panel,
-Electronic Control Box.
(c)
For analogic inputs:
-pressure transducers,
-temperature sensors,
- overheat detection loops.
(2) The interface systems are:
(a)
For the discrete outputs:
-Zone Controller,
-Environmental Control System.
(b)
For the ARINC inputs:
-Centralized Fault Display Interface Unit (CFDIU),
-Engine Interface Unit
(c)
For the ARINC outputs:
-Bleed Air Monitoring Computer (BMC) opposite,
-Centralized Fault Display interface Unit (CFDIU),
-System Data Aquisition Concentrator (SDAC). To indicate the system operation, the BMCs transmit digital outputs through the SDAC to the ECAM system. The digital outputs generate the system display. If an abnormal condition occurs, the ECAM system causes the single chime to sound and the MASTER CAUT light (amber) to flash. At the same time, the BMCs transmit discrete outputs to the AIR COND overhead panel, which causes the FAULT legend to come on amber. The BMCs are equipped with Built-In Test Equipment (BITE). They receive and transmit information from/to the CFDIU. This permits a self-test of the BMCs which is called up from the MCDU menu.
D. Fault Indicating
(1) With amber FAULT legend on ENG BLEED pushbutton switch, MASTER CAUT light and single chime:
-
after a 15 second delay when the pressure downstream of the bleed pressure regulator valve increases to 60 psig (Ref. Fig. 011)
-
after a 60 second delay when the temperature downstream of the bleed air precooler exchanger increases to 260 deg.C (Ref. Fig. 011)
