SECTION 1 - OPERATION
3124287 – JLG Lift – 1-1
SECTION 1. OPERATION
NOTE: This manual is intended as a supplement to the indi-
vidual machine’s Operators and Safety Manual.
1.1 INTRODUCTION & OPERATION
NOTE: It is the responsibility of the owner/user/operator/les-
sor/lessee to read & understand this manual and the
machine Operators & Safety Manual and to prevent
overloading the platform. Do not operate a machine
with a disconnected or inoperative Load Sensing
System.
The JLG-designed Load Sensing System (LSS) measures
platform load via four sensors mounted between the plat-
form and support structure. If the actual platform load
exceeds the selected Rated Load, the following will occur:
1. The Overload Visual Warning Indicator
will flash at the selected control position
(platform or ground).
2. The Platform and Ground Alarms will
sound 5 seconds On, and 2 seconds Off.
3. All normal movement will be prevented from the
platform control position (optional - ground control
functions may be prevented).
4. Further movement is permitted by:
a. Removing the excess platform load until actual
platform load is less than Rated Load.
b. Operation of the overriding emergency system
(Auxiliary Power Unit).
c. By an authorized person at the ground control
position (optional - ground control functions
may be prevented).
THE LOAD SENSING SYSTEM MUST BE CALIBRATED WHEN ONE
OR MORE OF THE FOLLOWING CONDITIONS OCCUR:
a. LSS System initial installation
b. LSS Module replacement
c. LSS Sensor removal or replacement
d. Addition or removal of certain platform mounted
accessories. (Refer to Calibration in Section 2)
e. Platform is removed, replaced, repaired or
shows evidence of impact.
THE LOAD SENSING SYSTEM REQUIRES PERIODIC FUNCTION
VERIFICATION NOT TO EXCEED 6 MONTHS FROM PREVIOUS
VERIFICATION. REFER TO TESTING & EVALUATION IN SECTION
2.
Calibration of the Load Sensing System is performed by
connecting the JLG Analyzer (Analyzer Kit, JLG part no.
2901443), to the Load Sensing System Module. All cali-
bration procedures are menu driven through the use of
the Analyzer. Note that Load Sensing System has an inde-
pendent Analyzer connection located near the module.
1.2 CONNECTING THE JLG CONTROL
SYSTEM ANALYZER
1. Connect the cable supplied with the analyzer, to the
LSS control module located in the platform and con-
nect the remaining end of the cable to the analyzer.
NOTE: Do not confuse the Host Control System and LSS
Module’s Analyzer Connections.
The cable (shown below) has a four pin connector at
each end of the cable; the cable cannot be con-
nected backwards.
2. Power up the Control System by turning the key to
the platform or ground position and pulling both
emergency stop buttons on.
