Packing List
Your package should include the following: Electric Expander (standard 100 amp, or larger 140 amp or 300 amp sensors), and a printed version of
this manual. Please check your box for printed addenda to this manual which may be included if changes were made after printing.
How the Electric Expander Works
The Electric Expander is compatible with our Flight Data Recorder V2/Pro, all Seagull systems, Car Data Recorder, and Boat Data Recorder
products. It is not compatible with our original Flight Data Recorder V1 product.
The Electric Expander works with your Data Recorder to
measure motor battery pack voltage and current. The Expander
measures current by means of a tiny, lightweight hall effects
current sensor ring. Battery pack voltage is measured by the
alligator clip attached to the expander. NOTE: a common
ground between your battery pack and the Recorder is required
for the voltage measurement to work correctly.
Connecting the Electric Expander to
the Recorder
Note: If you have a Secondary or Tertiary Electric Expander,
please refer to the Secondary Expander instructions for plugging
in your Expander to the Recorder.
Connect the polarized, 5 pin Electric Expander connector to the
recorder as shown in Figure 1a. NOTE: The plug is a tight fit
– slightly tilting the 5 pin connector back toward the center of
the Recorder can aid installation. If you still have problems
fitting it, you might need to lightly sand the top of the connector
(nearest the red wire) with sandpaper, but this should not be
necessary.
EXTREMELY IMPORTANT:
The
Electric Expander Connector **MUST** be connected correctly to your Recorder, or severe damage to the Recorder and
other equipment could occur, which will void the warranty. The Expander connects as shown in Figure 1A, to the right of
the USB connector, with the RED wire of the connector facing UP. If you are uncertain as to how to connect the expander,
don't hesitate to email us at support@eagletreesystems.com!
