SECTION 6. JLG CONTROL SYSTEM
6.1 INTRODUCTION
WHEN INSTALLING A NEW GROUND MODULE CONTROLLER IT IS NECESSARY
TO PROGRAM THE CONTROLLER FOR PROPER MACHINE CONFIGURATION,
INCLUDING OPTIONS.
AVOID PRESSURE-WASHING ELECTRICAL/ELECTRONIC COMPONENTS. IF
PRESSURE-WASHING IS USED TO WASH AREAS CONTAINING ELECTRICAL/
ELECTRONIC COMPONENTS, JLG INDUSTRIES, INC. RECOMMENDS A MAXIMUM
PRESSURE OF 750 PSI (52 BAR) AT A MINIMUM DISTANCE OF 12 INCHES (30.5
CM) FROM THESE COMPONENTS. IF ELECTRICAL/ELECTRONIC COMPONENTS
ARE SPRAYED, SPRAYING MUST NOT BE DIRECT AND FOR BRIEF TIME PERI-
ODS TO AVOID HEAVY SATURATION.
The JLG designed Control System is a 12 volt based motor con-
trol unit installed on the boom lift.
The JLG Control System has reduced the need for exposed ter-
minal 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 func-
tions.
Upper lift, swing, and drive are controlled by individual joy-
sticks. Steering is controlled by a rocker switch built in the top
of the drive joystick. To activate Drive, Lift, and Swing; pull up
the slide lock on the joystick and move the handle in the
desired direction.
The control system provides 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 in 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. Optional equipment includes a
soft touch system, head and tail lights, and ground alarm.
These options may be added later but must be programmed
into the control system when installed.
The Control System may be accessed with a custom designed,
direct connect hand held analyzer or wireless adapter using an
app on your Android or iPhone/iPad device. The analyzer or
wireless output displays two lines of information at a time, by
scrolling through the program.
Each module has a label with JLG part number and a serial number
containing a date code.
