Issue: The message "Stabilizer Disconnected!" appears on the video screen during OSD Pro startup.
Solution: This message indicates that the Guardian Expander is not detected by the system. Check your connections on the Guardian expander, and read further
troubleshooting steps below.
Issue: Guardian does not seem to be working correctly and the Guardian’s status LED IS flashing rapidly.
Solution: Make sure you have updated the OSD Pro, eLogger and Guardian firmware as described above.
Issue: Guardian does not seem to be working correctly and the Guardian’s status LED IS NOT flashing rapidly.
Solution: Make sure that the Guardian is connected correctly to the LCD/TX line on your eLogger and that your eLogger is powered. If the Guardian’s status LED is
blinking three times in a repeating fashion, then your unit has likely been damaged.
Issue: Servo deflections are limited, compared to when Stabilization is disabled.
Solution: Run the Servo Analysis Wizard under the Configure Radio Control menu. Make sure to assert full stick deflections when asked to turn and climb during the
wizard. See the section on the Servo Analysis Wizard under Guardian Stabilization.
Issue: Elevator or ailerons are unresponsive to radio commands
Solution: Make sure you have run the Servo Analysis Wizard after installing Guardian.
Issue: Servos are responding to control inputs, but not to movements of the airplane.
Solution: Ensure that the Guardian’s 4 pin cable is connected as described in the Connection and Mounting section above. Check that “Stabilizaton/Elevn Mixing On?”
is set to “YES” under the Configure Radio Control menu. Confirm that the Pitch, Roll and Overall Gains are set to their default values. If you are using the Aux2 input
for Overall Gain adjustment, ensure that your knob, switch, or slider is positioned to enable stabilization.
Issue: Heading Hold does not appear to be working or is drifting more than a few degrees per second.
Solution: If you have trimmed your airplane recently, you may need to execute the “Reset Cruise Sticks/Throtl” command under “Configure Radio Control.” The
Heading Hold feature only engages when your Roll command is very close to level flight. (Less than ~15% stick deflection)
