Post Installation Procedures
4.5.1 Wiring Inspection
1. Inspect all wiring and terminals to ensure security and attachment.
2. Check wiring for correct polarity and terminated to correct pins of the main connector.
4.5.2 Power-on Checks
1. Apply power to the unit and ensure the green POWER LED on top of the unit is on solid.
2. Ensure the amber STATUS LED on top of the unit is flashing steadily.
4.5.3 Configuration
1. If the modem is a RockAIR, carry out configuration of the RockAIR as per Section 5.5.
2. If the modem is a v2track, contact TracPlus to ensure the device is configured to communicate with the
AFDAU-T1.
3. If the modem is a DZMx, carry out configuration of the DZMx as per Section 5.6.
4. Check for the latest version of AFDAU-T1 firmware and, if required, carry out a firmware update per Section
5.3 (See Section 5 for PC Configuration Tool instructions).
5. Carry out configuration of AFDAU-T1 per Section 5.4.
4.5.4 Functional Checks
Discrete Sensors
1. While monitoring the AFDAU-T1 Diagnostics Tool, actuate each configured discrete sensor and ensure their
respective states are displayed.
2. If any states are actuating in reverse, invert the input in the Configuration Tool and try step 1 again.
Volume Sensors
3. Ensure that the volume readout of the AFDAU-T1 Diagnostics Tool matches the value on the volume gauging
system display.
a. For a Reabe Probe system move the ball up and down the length of the probe rod and ensure that the
Volume value on the Diagnostics Tool moves and matches the value on the Reabe cockpit and/or
remote gauge.
b. For a load cell type system either put a weight on the hook or temporarily disconnect the load cell at
the bulkhead connector and typically the weight value will start to move erratically or increase to a
large number. Ensure that any changes in weight are displaying on the Diagnostics Tool (negative
values on an MSI gauge will read as a zero in the Diagnostics Tool).
c. Bucket and tank equipped rotary-wing aircraft only: Select TANK on the Container Select Switch and
ensure the volume reading changes to follow the tank volume sensor. Actuate the tank controls such
as container door open and additive selects and pumps to ensure that the fields track the selected
container and operate correctly and in the correct sense.
Modem
4. Under the Modem heading in the Diagnostics Tool ensure a Latitude and Longitude are displayed and check
to ensure they make sense for your current location. (Expect large inaccuracies if carrying out checks inside a
hangar, a clear view of the sky may be required if unable to acquire position).
