ELEV ANGLE SENSOR FAULTY – NOT MOUNTED OR VOLTAGE OUT OF
RANGE
Reported when the elevation rotary sensor voltage is outside the range of accept-
able values.
ELEV ANGLE SENSOR HAS NOT BEEN CALIBRATED Reported when the rotary calibration value does not exist.
ELEVATION PROX SWITCH PERMANENTLY CLOSED
Reported when the elevation rotary sensor is reporting above elevation and the
elevation proximity switch is still closed.
ELEVATION PROX SWITCH PERMANENTLY OPEN
Reported when the elevation rotary sensor is reporting stowed and the elevation
proximity switch is open.

REAR RIGHT LEVELING JACK PRESSURE TRANSDUCER FAILURE Reported when the rear right leveling jack pressure reading is well below 0PSI.
PLATFORM OVERLOAD
Reported when the overload is setup and the LSS is reading the platform is over-
loaded.
FRONT LEFT LEVELING JACK STOW SWITCH PERMANENTLY CLOSED
Reported when the FRONT LEFT Leveling Jack Stow Switch is closed and the
FRONT LEFT pressure transducer reads "Set" pressure.
FRONT RIGHT LEVELING JACK STOW SWITCH PERMANENTLY CLOSED
Reported when the FRONT RIGHT Leveling Jack Stow Switch is closed and FRONT
RIGHT pressure transducer reads "Set" pressure.
REAR LEFT LEVELING JACK STOW SWITCH PERMANENTLY CLOSED
Reported when the REAR LEFT Leveling Jack Stow Switch is closed and the REAR
LEFT pressure transducer reads "Set" pressure.
REAR RIGHT LEVELING JACK STOW SWITCH PERMANENTLY CLOSED
Reported when the REAR RIGHT Leveling Jack Stow Switch is closed and the REAR
RIGHT pressure transducer reads "Set" pressure.
ELEV ANGLE SENSOR HAS NOT BEEN CALIBRATED
Reported when elevation height calibration has not been performed or is not log-
ical (increasing voltages from stowed). Vehicle assumed to be at full height.
ELEV ANGLE SENSOR FAULTY - NOT MOUNTED OR VOLTAGE OUT OF
RANGE
Reported when elevation angle sensor is outside the 0.30V to 4.85V range. Vehi-
cle assumed to be at full height.
ELEV ANGLE SENSOR NOT DETECTING CHANGE
Reported when elevation angle sensor voltage does not change for 5 sec during
l if t u p > 20 %. Ve hicl e ass umed to be at fu ll he ight . Fa ul t c le are d o nl y in va li d
stowed position.
