JLG LSS Scissors - Manual (Page 38)

SECTION 5 - SERVICE - (LE, MRT, RTS, ES, RT)
5-2 – JLG Lift – 3124288
5.2 CALIBRATION
Procedure
1. Plug the JLG Analyzer into the LSS Module on the
LE, MRT and RTS or the Host Control System on the
ES and RT and enter the Access Level 1 Password.
Do not confuse the Host Control System and LSS
Module’s Analyzer Connections. Proceed to the
ACCESS LEVEL menu and enter the Access Level 1
Password (33271).
2. Park the vehicle on a level surface. The platform
should be fully stowed and level within ± 5° (both
directions).
3. Configure the LSS Module for the proper model and
Desired Units. On LE, MRT and RTS, proceed to the
LSS Module’s MACHINE SETUP, MODEL sub-menu
and select “MODEL=4069LE, 3369LE, 500RTS, or
260MRT”. 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.
EARLY RT’S REQUIRE A CONFIGURATION TO THE LSS MODULE.
PLUG THE JLG ANALYZER INTO THE MODULE’S CONNECTION
BENEATH THE DECKAND ENTER THE ACCESS LEVEL 1 PASS-
W O R D ( 3 3 2 7 1 ) . U N D E R M A C H I N E S E T U P E N S U R E T H A T
MODEL=260MRT.
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. Once determined, the contributions of all
permanently-fixed JLG Accessories mounted in the
platform 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 (LE,
MRT and RTS) or the Host Control System (ES and
RT).
2. Park the vehicle on a level surface. The platform
should be fully stowed and level within ± 5° (both
directions).
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).
4. Use the Technician’s Weight to Evaluate. The techni-
cian should enter the platform and record the PLT-
LOAD reading while standing in the center of the
platform, and then each corner. The average of the
readings should be the estimated weight of the tech-
nician. The range of the readings should be no more
than 40lbs (18kg) (max PLTLOAD reading – min PLT-
LOAD reading).
