ELEV ANGLE SENSOR FAULTY – NOT MOUNTED OR
VOLTAGE OUT OF RANGE
Reported when the elevation rotary sensor voltage is outside
the range of acceptable 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.
FRONT LEFT LEVELING JACK PRESSURE TRANS-
DUCER FAILURE
Reported when the front left leveling jack pressure reading is
well below 0PSI.
FRONT RIGHT LEVELING JACK PRESSURE TRANS-
DUCER FAILURE
Reported when the front right leveling jack pressure reading is
well below 0PSI.
REAR LEFT LEVELING JACK PRESSURE TRANS-
DUCER FAILURE
Reported when the rear left leveling jack pressure reading is
well below 0PSI.
REAR RIGHT LEVELING JACK PRESSURE TRANS-
DUCER 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 overloaded.
FRONT LEFT LEVELING JACK STOW SWITCH PERMA-
NENTLY 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 PER-
MANENTLY 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 PERMA-
NENTLY 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 PERMA-
NENTLY 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 per-
formed or is not logical (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. Vehicle 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 lift up >20%. Vehicle assumed to be at
full height. Fault cleared only in valid stowed position.
