The weight of all the system is 100 kg (220.5 lbs) for A330, A340-200 and A340-300, and 120 kg (264.6 lbs) for A340-500/600. On the left hand side of the air conditioning Pack 1, there is the Inert Gas Generating System (IGGS) pallet. The IGGS contains Air Separation Modules (ASMs), different valves and sensors for the temperature, pressure, and oxygen concentration. The primary function of the IGGS pallet is to separate the oxygen and the nitrogen. On the right hand side, there is the Cooled Service Air System (CSAS). The system uses the ram air which is first used for the air conditioning system. The system has a small heat exchanger installed upstream of the classical heat exchanger, a bypass shut-off valve, pressure and temperature sensors. The two systems are part of different ATA chapters: - IGGS is ATA 47 and is supplied by PARKER, - CSAS is ATA 21-58 and is supplied by LIEBHERR.

It prevents damage caused to the ASMs by an over-temperature condition. If the temperature is higher than the pre-determined detection threshold, the IGGS Control Unit (ICU) isolates the system. T2 also supplies a temperature reading in support of the system health monitoring. To do this, it uses a sampling from the oxygen sensor. T2 has two probes to measure the temperature of the airflow that comes from the CSAS. Temperature measurements from one probe are monitored by the analog controller part and measurements from the second probe are managed in the digital controller part. These two probes can control the system to close if an over-temperature is detected. PRESSURE SENSOR (P2) The IGGS pressure sensor (P2) is installed between T2 and the ASMs inlet. This sensor monitors the IGGS and detects over-pressure and under-pressure conditions.

The ASM is a semi-permeable hollow-fiber membrane bundle contained in a pressure containment canister. This canister is a cylinder with 3 ports. The fibers are parallel to the axis of the cylinder, and connect the air inlet with the Nitrogen Enriched Air (NEA) outlet. The outer side of the fiber communicates with the Oxygen Enriched Air (OEA) outlet. Thus, the gases go through the fiber bundle and then go out of the canister through the OEA outlet. Most of these gases are oxygen, carbon dioxide and vapors of water. Nitrogen molecules will flow directly from the air inlet to the NEA outlet because they are bigger than the permeable fiber walls. NOTE: There are 2 ASMs on the A330 and A340-200/300, and 3 on the A340-500/600.

The oxygen sensor also measures the NEA pressure. The sensor sends the signals to the ICU, which then sends fault data to the Centralized Maintenance System (CMS). The oxygen sensor is started one time in each flight during the cruise flight phase. During the warm-up period, the unit does an automatic Power-up Built-In Test Equipment (P-BITE) test. Fault indications are inhibited before the end of the warm-up period.

The DFSOV is closed when the FTIS is not in operation. In operation, the DFSOV closes if: - The NEA flow pressure becomes less than 15 psi (1.0342 bar), - The NEA flow pressure becomes more than 60 psi (4.1369 bar), - And/or the NEA flow temperature becomes more than 85°C (185.00°F). The ICU supplies 28V DC power to the two DFSOV solenoids. Each solenoid operates a DFSOV poppet which causes the ICU to open the DFSOV and to adjust the NEA flow to the fuel tank. The valve includes position indication switches (one for each poppet). The switches are used by the ICU to supply DFSOV status information for system monitoring and fault detection. The valve also has a mechanical visual position indicator on each poppet to help line maintenance during the troubleshooting of system anomalies when the valve is installed on the aircraft. The valve is failsafe in the closed position. In normal operation, it closes when there is low upstream pressure or a defective solenoid. When closed, the valve prevents all upstream fuel leakage with a maximum of 20 psig back-pressure. GCL13151 - GEHT0M0 - FM47D2000000001 There are four operational modes: - Closed position => A/C on ground, - Low-flow position => During climb and cruise, - Mid-flow position => During approach, - And high-flow position => During descent.
