Introduction
WHEN INSTALLING A NEW POWER MODULE CONTROLLER ON THE MACHINE, IT
WILL BE NECESSARY TO PROGRAM THE CONTROLLER FOR THE PROPER
MACHINE CONFIGURATION, INCLUDING OPTIONS.
IT IS A GOOD PRACTICE TO AVOID PRESSURE-WASHING ELECTRICAL/ELEC-
TRONIC COMPONENTS. SHOULD PRESSURE-WASHING BE UTILIZED TO WASH
AREAS CONTAINING ELECTRICAL/ELECTRONIC COMPONENTS, JLG INDUS-
TRIES, INC. RECOMMENDS A MAXIMUM PRESSURE OF 750 PSI (52 BAR) AT A
MINIMUM DISTANCE OF 12 INCHES (30.5 CM) AWAY FROM THESE COMPO-
NENTS. IF ELECTRICAL/ELECTRONIC COMPONENTS ARE SPRAYED, SPRAYING
MUST NOT BE DIRECT AND BE FOR BRIEF TIME PERIODS TO AVOID HEAVY SAT-
URATION.
The JLG designed Control System is a 48 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 and max.-
speed for all boom, drive, and steering functions.
The main lift, swing, and drive are controlled by individual joy-
sticks, 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 motor controller will control current output, as pro-
grammed for smooth operation and maximum cycle time.
Ground control speeds for all boom functions can also be pro-
grammed into the motor controller. The motor controller also
features an adjustable time limit for positive traction.
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 an
hour meter, beacon light, function cutout, and ground alarm.
These options may be added later but must be programmed
into the motor controller when installed.
The Control System may be accessed in one of two ways: Uti-
lizing 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.
NOTE: Each module has a label with the JLG part number and a
serial number which contains a date code.
The following instructions are for using the hand held ana-
lyzer.
