6.1 INTRODUCTION
NOTE: All 800A and 800AJ machines from S/N 65534 incor-
porate ADE (JLG Control System). The following
machine serial numbers prior to S/N 65534 also uti-
lize ADE: 62045, 62797, 63013, 63665, 63975,
64000, 64007, 64009, 64015, 64017, 64390, 64392,
and 64411.
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 upper lift, swing, and drive are controlled by individual
joysticks, with steering being controlled by a rocker switch
built into the top the drive joystick. To activate Drive, Lift,
and Swing simply pull up on the slide lock location on the
joystick and move the handle into the direction desired.
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. Optional equip-
ment 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 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.
