_______________________________________________________________
1. General
_______
The hydraulic pressure indicating system monitors the hydraulic pressure at different locations in the three hydraulic systems. Two types of detectors are used, pressure switches and pressure transmitters. The data is used for visual on the ECAM display unit and for FAULT action from the ECAM. Discrete signals are also sent to the overhead panel. Some data is sent to other aircraft systems.

__________________
R **ON A/C 001-049, 051-058, 101-101,
The hydraulic pressure indicating system uses two different types of pressure switch and a single type of pressure transmitter to get system pressure information. The system pressure is monitored:
-
downstream of each engine-driven pump (Yellow and Green systems),
-
downstream of the electric pump of the Blue system,
-
at the HP manifolds (Green, Blue and Yellow systems),
-
at the brake manifold (Yellow system).
Type 1 pressure switches are installed downstream of the engine-driven pumps. They monitor the output pressure of the pump.

Type 2 pressure switches are installed downstream of the Blue electric pump and on the three HP manifolds. The first one monitors the output from the Blue electric pump. Those on the HP manifolds monitor the HP of the individual systems downstream of the solenoid valves (1150GP, 2150GP, 3150GP).
