6.1 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 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.
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 an hour meter, beacon light, function cut-
out, 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 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.
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.
