4.4.5.5 Self-Test
The Self-Test (see Figure 4-4) is used to check the status of WX-500 after power up.
1. Press the “Self-Test” button to start test.
2. During the test an “In Progress” message is shown.
3. The results of the test are Passed, Degraded, or Failed.
A “Passaged” message indicates that the WX-500 is operational and no errors are being
detected.
A “Degraded” message has amber text and indicates that information is missing.
Cycle power to the WX-500 and the NGT-9000 and check the startup self-test to see if the
degraded status has been cleared. If not note the fault code and description. Refer to the WX-
500 Installation Manual for fault isolation information.
A “Failed” message has red text and is followed by a “Fault Code” number and a display of the
problem.
Cycle power to the WX-500 and the NGT-9000 and check the startup self-test to see if the
failed status has been cleared. If not note the fault code and description. Refer to the WX-500
Installation Manual for fault isolation information. Also the MPC (MAT) can be used to view
fault data (see Installation Checkout section).
Errors 01 thru 15, 21, 25 thru 36, 40 thru 42 typically indicate an internal failure and that the
unit needs to be sent to the factory for repair.
4.5 USING THE MAINTENANCE PC
The Maintenance PC (MPC) and Lynx Maintenance Application Tool (MPC (MAT)) are used to interface
with the Lynx NGT-9000 to load software/firmware/databases, view factory / version data, retrieve fault /
event logs, data recording, and simulating live data.
These procedures assume the following:
Power is being supplied to the aircraft and unit and system components.
The correct MPC (MAT) software is being used to load software. See the General Information
section (Software Versions) for software details. Note - Each version of software for the Lynx NGT-
9000 requires a specific MAT software version that is compatible.
The software to be loaded is available on the MPC being used.
The MPC (MAT) is active on the MPC.
The MPC is interfaced to the unit.
The MPC and unit are communicating and the unit is in Maintenance Mode.
Additional instructions on using the MPC are given in the Installation Checkout section.
