JLG LSS Boom - Manual (Page 30)

SECTION 2 - SERVICE - ENGINE POWERED BOOM LIFTS
2-8 – JLG Lift – 3124287
Enter the Access Level 1 Password (33271). Next,
proceed to the MACHINE SETUP, LOAD sub-menu
and select “2=CUTOUT PLT”. Press the RIGHT
ARROW to view the MACHINE SETUP, LOAD TYPE
sub-menu. Set it to “1=4 UNDER BASKET” to select
the Load Sensing System with four Shear Beam
Load Cells beneath the platform. At this point, it is
likely that the Host Control System’s Visual and
Audible Warnings for the Load Sensing System will
be active (since the LSS Module is un-calibrated).
12. Perform a Calibration of the Load Sensing System.
Refer to the Calibration procedure in this manual to
prepare the Load Sensing System for use.
2.3 CALIBRATION
Procedure
1. Plug the JLG Analyzer into the LSS Module and
enter the Access Level 1 Password. Do not confuse
the Host Control System and LSS Module’s Analyzer
Connections. The Host Control System’s connection
is mounted beneath the Platform Console Box, and
the LSS Module’s connection hangs from a short
harness near the module. Proceed to the ACCESS
LEVEL menu and enter the Access Level 1 Pass-
word (33271).
2. Level the Platform. The platform should be approxi-
mately level for calibration. Level the platform from
Ground Control (if necessary) to within +5 degrees.
3. Configure the LSS Module for Boom Lift mode and
Desired Units. Proceed to the LSS Module’s
MACHINE SETUP, MODEL sub-menu and select
“MODEL=BOOM LIFT”. Press the RIGHT ARROW to
view the Units Selection. Select “UNITS=LBS” for
platform load measurement in Pounds, and
“UNITS=KG” for measurement in Kilograms.
4. Remove everything except JLG Accessories from
the Platform. Empty the platform to allow the Load
Sensing System to record its weight during calibra-
tion. All tools, debris, and customer-installed devices
shall be removed. Permanently-fixed JLG Accesso-
ries shall remain and their contribution toward Rated
Load will be accounted for in the next step.
5. Configure the LSS Module for JLG Accessories. The
contribution of each permanently-fixed JLG Acces-
sory toward Rated Load must be determined. JLG
Accessories are decaled with their effective contribu-
tion toward Rated Load. If this decal is missing, ref-
erence the appropriate manual for the JLG
Accessory or consult the table within this manual.
Once determined, the contributions of all perma-
nently-fixed JLG Accessories mounted in the plat-
form of the vehicle shall be added together and
entered in the Analyzer’s PERSONALITIES, ACC’Y
display (using the proper units).
6. Execute a Calibration via the JLG Analyzer. Proceed
to the Analyzer’s CALIBRATION top level menu and
press ENTER. Press ESC to abort a calibration or
ENTER to calibrate (tare). If successful, the Analyzer
will display “COMPLETE”. If unsuccessful, a mes-
sage will be displayed that will help lead to a resolu-
tion (reference the Troubleshooting section of this
manual). Press ESC to return to the top level menu.
Testing & Evaluation
Refer to the Troubleshooting section of this manual if the
Load Sensing System fails to meet these guidelines.
1. Plug the JLG Analyzer into the LSS Module. Do not
confuse the Host Control System and LSS Module’s
Analyzer Connections. The Host Control System’s
connection is mounted beneath the Platform Con-
sole Box, and the LSS Module’s connection hangs
from a short harness near the module.
2. Level the Platform. The platform should be approxi-
mately level for analysis, or the guidelines below will
not be applicable. Level the platform from Ground
Control (if necessary) to within +5 degrees.
3. Observe the Empty Platform Weight. Proceed to the
DIAGNOSTICS, PLTLOAD sub-menu and observe
the measured platform load. All tools, debris, and
customer-installed devices shall be removed during
evaluation. Ideally, the PLTLOAD should be zero but
can vary +15lbs (± 7kg). Further, the reading
should be stable and should not vary by more than
+2lbs (±1kg) (unless there is heavy influence from
wind or vibration).
