 (2) Malfunction Detection OVERHEAT thermo-switches operate if the stator temperature of the recirculation fans 14HG (15HG) goes up to 160 DEG.C (320.00 DEG.F) +/- 8 DEG.C (46.40 DEG.F). They will remove the ground from the power relays 5HG (6HG), the fans will stop and the fan fault relays 10HG (9HG) will open. The fan fault relays signal the Centralized Fault Display System (CFDS) and the Electronic Centralized Aircraft Monitoring (ECAM) system. To start the cabin fans again you must push the CAB FANS switch twice, once to switch OFF and once to switch ON. You must find and repair the fault before you do this.

 B. Controls and Indications If a recirculation fan fails, the recirculation fan control circuit transmits signals to the Centralized Fault Display System (CFDS) and to the Electronic Centralized Aircraft Monitoring (ECAM) for display after flight. The ECAM will give an immediate display only if both fans fail.
