6 – LEAKAGE SOURCE IDENTIFICATION
When there is a pneumatic problem identified during the performance diagnostic test, there are 3 potential
sources that can cause the problem: the valves, the pumps, or the tubes. This section guides to identify
the source of failure is identified.
6.1 Valve
Investigation
The valves are a potential source of leakage. There are 2 identical valves connected to each pressure
channel. One is the standard operational valve, and the second is a backup for fast pressure release. Each
valve is connected to the Falcon board with 2 screws, and to the pressure channel via a slightly wider
silicon tube. In order to isolate the pneumatic problem in a specific pressure channel, disconnect the
silicon tubes from the valves and instead connect 2 closed loop tubes (PVC0108) to the open pressure
channel tube ending that was previously connected to the valves.
