Below is a list of problems that may be encountered, and steps to remedy them. If your particular issue is not addressed by the
below, see the Support page on
http://eagletreesystems.com or email [email protected] . Include a full description of your
problem, your machine configuration, brands/models of receivers, transmitters and servos, application and Recorder firmware version
if possible (from Help->About in the app) and any other relevant
details.
Issue: I do not see motor voltage and/or current values changing after
using the Expander.
Solution:
•
Make sure that you have selected logging of voltage and/or
current in the “Choose What to Log” dialog box under the
Tools menu.
•
If voltage measurement is not working, but current is working,
see the “ESC’s with isolation between BEC/Throttle ground
and Main Battery Ground” section above.
•
If Current is not working correctly, please verify that the Ring
sensor is correctly installed on the Electric Expander harness.
Please see the figure below.
•
Ensure that you have selected motor voltage and/or current in the “Choose What to Display” dialog box under the Tools
menu.
•
Double check your connections to ensure that the Recorder is connected correctly to the Electric Expander, and the battery.
•
Ensure that you are operating within the ranges listed in the Specifications section below.
Issue: My Electric Expander seems to be out of calibration. The readings I receive for current and/or voltage are somewhat incorrect
or differ slightly from my favorite meter.
Solutions:
•
If you have a “High Voltage” recorder, or a “High Current” (140 or 300 amp) Electric Expander, ensure you have made the
“Custom Hardware Options” settings as described above.
•
If the current sensor appears to be reading incorrectly, make sure you’ve performed the steps in the “Zeroing the Current
Sensor for First Time Use” section above.
•
ADVANCED: If current and/or voltage seem to be reading slightly incorrectly, or you wish to calibrate the readings to a
particular meter you use, click “Tools, Calibrate Pack Voltage and Amperage Readings” in the windows application, and
follow the instructions.
