Introduction
WHEN INSTALLING A NEW POWER MODULE CONTROLLER ON
THE MACHINE, IT WILL BE NECESSARY TO PROGRAM THE CON-
TROLLER FOR THE PROPER MACHINE CONFIGURATION, INCLUD-
ING OPTIONS.
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 48 volt based
motor control 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 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 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
programmed into the motor controller. The motor control-
ler also features an adjustable time limit for positive trac-
tion.
