9.10.3 LSI System Calibration
a. Standard Calibration
To calibrate the LSI, certain conditions must be met:
• The sensor must be installed according to Section
9.10.2, “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 straight driving
over a distance of at least 2 m (6.5 ft) being the last
movement before entering 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 lower the outriggers. Shut
the machine OFF.
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 ignition 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 and boom fully 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
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. Perform the LSI- CAN Check PT to finalize the
calibration. Refer to Section 9.10.4, “LSI-CAN Check PT.”
