3.4 Installation Approval
The TXA201 Triaxial Accelerometer requires FAA approval for installation on an N-
registered, type-certificated aircraft. Installation is not authorized by this manual.
4 TESTING
4.1 Fault Indication
This accelerometer does not include any fault indication features.
4.2 Pre-Installation Check
Each accelerometer completes an acceptance test prior to delivery. Unless damage
during shipment or storage is suspected, a pre-installation test should not be
required.
4.3 Functional Test Procedure
If damage or troubleshooting suggests that the performance of the acceleromter
may be suspect, a function test may be performed using the following procedure:
Requirements
•
28VDC Power Supply
•
DC Voltmeter
•
Tooling, fixtures, or other items that will allow the accelerometer to be rested
on each of its six faces in a flat and level orientation.
•
A test harness may be constructed to interface with the pinouts listed in
Section 2.2.1
Connect the accelerometer to power and ground and connect to the output pins as
shown in Section 2.2.1
Place the accelerometer flat and level on each of its six sides as shown in Table 2
below.
Record the voltage output on the pins indicated in Table 4 and ensure they are
within the listed range.
Repeat the test for the remaining positions of the accelerometer.
If any recorded voltages are out of range, please see the contact information listed
in Section 6.
4.4 Post-Installation Check
After installation, the accelerometer data provided to the receiving FDR or other
equipment should be verified using a compatible data download and analysis tool
