ROTATING TRANSFORMER
The rotating transformer transmits the tire pressure
value from the wheel to the detection unit.
DETECTION UNIT
The detection unit comprises a microprocessor which
provides data processing and distribution of each tire
pressure including normal and abnormal pressure
signals for ECAM indication and CFDS monitoring.
The TPIS detection unit permanently performs a test
of the unit itself, the rotating mechanism and the
pressure transducer. The test is only stopped for data
processing and distribution.
INTERFACES
The signal from the Landing Gear Control and Interface
Unit (LGCIU) is used to change the tire pressure
threshold for on ground or in flight warnings.
Note that tire pressure warnings are only memorized
by the BITE when at least one engine is running to
prevent false warnings during wheel change.

SELF EXAMINATION
What signal is delivered by the pressure transducer?
A - A DC signal which depends on the tire
pressure.
B - A frequency signal which depends on the
tire pressure.
C - A pneumatic signal equal to the tire
pressure.
What is the rotating mechanism used for?
A - To change the pressure voltage into a
frequency signal.
B - To transmit the tire pressure signal
from the wheel to the axle.
C - To perform the permanent test of the
system.
