LSS SYSTEM
The JLG-designed Load Sensing System (LSS) measures plat-
form load via a sensor mounted in the platform support struc-
ture. 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 (plat-
form 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 plat-
form control position (optional - ground control func-
tions may be prevented).
4.
Further movement is permitted by:
a.
Removing the excess platform load until actual plat-
form 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 posi-
tion (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 Sensor removal or replacement
b.
Addition or removal of certain platform mounted
accessories. (Refer to Calibration)
c.
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 TEST-
ING & EVALUATION.
All calibration procedures are menu driven through the use of
a JLG Analyzer.
