SECTION 6. JLG CONTROL SYSTEM
6.1 INTRODUCTION
WHEN INSTALLING ANY NEW MODULE CONTROLLER ON THE
MACHINE, IT WILL BE NECESSARY TO PROGRAM THE CONTROL-
LER FOR THE PROPER MACHINE CONFIGURATION, INCLUDING
OPTIONS AND PROPERLY CALIBRATE THE TILT SENSOR.
IT IS A GOOD PRACTICE TO AVOID PRESSURE-WASHING ELEC-
TRICAL/ELECTRONIC COMPONENTS. SHOULD PRESSURE-
WASHING BE UTILIZED TO WASH AREAS CONTAINING ELECTRI-
CAL/ELECTRONIC COMPONENTS, JLG INDUSTRIES, INC. REC-
OMMENDS A MAXIMUM PRESSURE OF 750 PSI (52 BAR) AT A
MINIMUM DISTANCE OF 12 INCHES (30.5 CM) AWAY FROM
THESE COMPONENTS. IF ELECTRICAL/ELECTRONIC COMPO-
NENTS ARE SPRAYED, SPRAYING MUST NOT BE DIRECT AND BE
FOR BRIEF TIME PERIODS TO AVOID HEAVY SATURATION.
The JLG designed Control System is a 12 volt based con-
trol unit installed on the boom lift.
The JLG Control System has reduced the need for
exposed terminal strips, diodes and trimpots and provides
simplicity in viewing and adjusting the various personality
settings for smooth control of: acceleration, deceleration,
creep, min speed, and max.-speed for all boom, drive,
and steering functions.
The control system will control the voltage output to the
valves and pump, as programmed for smooth operation
and maximum cycle time. Ground control speeds for all
boom functions can also be programmed into the control
system.
The JLG Control System controller has a built in LED to
indicate any faults. The system stores recent faults which
may be accessed for troubleshooting.
The Control System may be accessed utilizing a custom
designed, hand held analyzer (Analyzer Kit, JLG part no.
2901443) which will display two lines of information at a
time, by scrolling through the program.
