9.16.3 LSI System Calibration
a. Standard Calibration
To calibrate the LSI, certain conditions must be met:
• The sensor must be installed according to Section
9.15.2, “LSI Sensor.”
• The machine control system must be powered on for
at least 10 minutes before calibration.
• The operator must remain in the cab.
• The calibration shall be conducted with the standard
carriage and forks attached and weights as
necessary ( a range of 60-80% of maximum weight
capacity).
• The machine must be on a level surface with the
wheels steered straight and park brake off, with
str aight drivin g over a distanc e of at le ast 2 m (6. 5 ft)
being the last mov eme nt before ente ri ng a
calibration point.
• While utilizing the LSI override button, 10 times lift
and lower the boom stopping suddenly to induce the
rear axle to bounce.
• Position the rear tires centrally on the scales.
• The calibration must be completed within 30 minutes
after starting procedure.
Calibration Procedure:
1. Start and position the machine to perform the
calibration procedure.
2. Remove the standard carriage and weight assembly.
3. Fully retract the boom and if equipped, lower the
outriggers. Shut the machine OF F.
4. With ignition key in OFF position, press and hold
SYSTEM CHECK button on LSI display and turn
ignition key to engine START position. Release the
igniti on key when engine start is achieved, but
continue to hold SYSTEM CHECK button on LSI
display until the orange LED on LSI display goes out
and buzzer sounds (approximately 3 seconds).
Release SYSTEM CHECK button.
5. The LEDs will perform a rolling sequence. When
only the third green LED illuminates, press the
SYSTEM CHECK button.
6. The first green LED then illuminates. With no
attachment, outriggers down (if equipped) and boom
retracted, lift boom to maximum boom angle.
7. Press the SYSTEM CHECK button on the LSI
display and release. The first 3 green LEDs will
illuminate. The third then second green LEDs will go
out as the calibration point is recorded.
8. The first green LED goes out and buzzer sounds
then the red LED illuminates.
9. Lower boom until level. If equipped, fully raise the
outriggers. Pressing the LMI Override button may be
required to lower the boom.
10. Attach the previously removed standard carriage,
forks and weight.
11. Slowly extend the boom until the rear axle weight in
the following table is achieved.
12. Press the SYSTEM CHECK button on the LSI
display and release. As the calibration point is
recorded, buzzer sounds and the LEDs will flash and
perform a sequence until all are flashing.
13. Turn the ignition key to OFF. LSI is now calibrated.
14. Perform the LSI-CAN PT Check. Refer to Section
9.16.4, “LSI-CAN Check PT.”
b. Field Calibration
To calibrate the LSI, certain conditions must be met:
• The sensor must be installed according to Section
9.15.2, “LSI Sensor.”
• The test weight matches the model being calibrated
in the table shown below.
• The calibration shall be conducted with standard
carriage and forks attached to the machine.
• While utilizing the LSI override button, 10 times lift
and lower the boom stopping suddenly to induce the
rear axle to bounce.
Note: If the test weight is not known, follow steps 1 & 2.
