Category Failure Description
MINOR Thermal protection sensor reading
out of range.
MAJOR FPA temperature sensor reading
out of range. Failed to read valid
temperature from the FPA of the IR
sensor.
MINOR Defective memory on DCE card.
Category Failure Description
MAJOR Internal gimbal temperature is too
hot for the EON sensor to operate.
MINOR Focus elements failed to reach a
specific position in a specific time.
MAJOR Focus servo loop of EON sensor
not responding properly.
No focus control available for EON
sensor.
MINOR Failed to communicate with EON
sensor.
MINOR The lens temperature sensor is
defective.
MINOR The filter mechanism was unable to
reach or sustain a commanded

Recommended Action
Check turret temperature in the
Gimbal Menu. If gimbal temperature
is <70°C (<158°F) and IR camera is
still operational, continue to use
system. If gimbal temperature is
>70°C (>158°F), turn off turret and
allow system to cool for at least 1
hour before operating.
No action. Contact L-3 Wescam.
Image may still be available.
No action. Contact L-3 Wescam.
Replace Turret.
Recommended Action
Turn turret off and allow to cool.
Verify that EON sensor focus can still
be adjusted. If focus control loss
impacts mission, replace turret.
Execute a BIT from the Level 2 EON
Menu. If failure persists, replace
turret.
Camera Failure. The recommended
action indicates to verify if video is
lost. This is not necessarily the case.
Camera Failure can occur if
communication control is lost. The
video may still be present but control
of camera is impacted.
The temperature sensor source may
be a sensor located somewhere
other then the lens.
Warning only.
No action. Contact L-3 Wescam.
