• LiftUpState = PREVENTED
• PlatformHeightValue assumed
to be Full Elevation
• OverLoadState = TRUE if
{MACHINE SETUP->LOAD≠NO)
The input voltage from the Elevation Angle Sen-
sor that measures lower arm motion did not
increment/decrement properly while the vehicle
was lifting down or up. Check mounting, review
sensor wiring against the electrical schematic, or
replace the sensor to clear the message.
•
Elevation1RawValue is Stagnant (within 0.30
degrees) while lifting up or lifting down for
5000mS, or value is decrementing while lift-
ing up, or incrementing while lifting down.
Not applicable when the following conditions are
TRUE:
•
Lifting Down AND PlatformHeightValue <
PhysicalMinHeigh5%*Platform-
HeightRange
•
Lifting Up AND PlatformHeightValue> Physi-
calMinHeigh 95%*PlatformHeight-
Range
•
Lifting Up AND PumpCommand < {PERSON-
ALITIES->LIFT->UP MIN} + (40%* ({PER-
SONALITIES->LIFT->UP MAX}-
{PERSONALITIES->LIFT->UP MIN}))
•
Lifting Down AND CurrentCommand is <
{PERSONALITIES->LIFT->DOWN MIN}
+(40%*({PERSONALITIES->LIFT->DOWN
MAX}-{PERSONALITIES->LIFT->DOWN
MIN}))
Not applicable when the following faults are
active:
•

• LiftUpState = PREVENTED
• PlatformHeightValue assumed
to be Full Elevation for the pur-
poses of other interlocks
• OverLoadState = TRUE if
{MACHINE SETUP->LOAD≠NO)
Calibrate the Elevation Angle Sensor using the
calibration procedure to clear the message.
•
The Elevation Sensor’s Calibration EEPROM is
set to the signature implanted by the In-Cir-
cuit Test Fixture (has never been calibrated by
the factory). Retained until Calibration
EEPROM is over-written by a valid calibration.

Need to recheck this setting for the redundant
sensors as well if MACHINE SETUP-

The Ground Module's Application and Constant-
Data Versions do not match which could lead to
improper operation therefore machine shall not
