Falcon Service Manual

Test: Once the
Start
button is selected (or the
Redo
button if the test is repeated), all Falcon pumps
become active, and start inflation to open air. The online instructions on the side guide the tester
to close the air output of each colored air tube ending with the finger according to a specific color
order. Once the tube ending is closed with the finger, pressure should be generated in that specific
channel and the instructions guide the tester to the next tube.
Pass/Fail: Pass is considered when all of the tubes generate pressure according to the instructed
order. If a a specific channel does not generate pressure when shutting the tube, then the tester
should press the Fail button on the right.
Troubleshooting:
a)
The external tube sub-assembly may be leaking. Replace PVC0064 and retest.
b)
One of the pneumatic elements: valves, pumps or internal tubes, may be responsible for
leaking. Follow the instructions in the section for leakage source identification to pinpoint the
leakage source.
4.2
Verify Calibration Test
Objective: This test verifies the calibration of the pressure sensors.
Setup: Connect the external pressure sensor (PVC0106) in parallel to one of the 2 free tube ends of
the pressure chamber (PVC0107) tubing. Turn PVC0106 on by pressing the power on button (top
left button).
Test: Connect the free tube ending of PVC0107 to the tested pressure channel tube of PVC0064,
and press Ok to start test. The corresponding pump should inflate to a set target pressure. Wait
until a window opens and type in the respective field the pressure shown on the external pressure
sensor device PVC0106. Press Ok and to complete the test for the current channel. Press NEXT to
continue with the test of the next channel.
Pass/Fail: Pass is defined as a relative error of less then 5% between the tested channel pressure
and the external measured pressure.
Troubleshooting:
If the Verify Calibration Test cannot be completed due to failure to build a steady pressure in the
pressure chamber, then one of the pneumatic elements: valves, pumps or internal tubes, may be
responsible for the failure. Follow the instructions in the section for leakage source identification
to pinpoint the leakage source, and repeat the calibration test.
If the Verify Calibration Test fails, then the failed channel name becomes active in the protocol list
on the left hand side for the next Calibrate test. The failed channel needs to be calibrated, and then
repeat the calibration verification test.
4.3 Calibration
Objective: This procedure is carried out only when the calibration test fails, in order to re-calibrate
the pressure sensors of the failed channels.
Setup: Maintain the same setup of the previous Verify Calibration test.
