3.5 CONTROLS AND INDICATORS FOR
PROPORTIONAL CONTROL
The machine is equipped with control panels that use
symbols instead of words to indicate control functions.
Refer to Symbols figure for these symbols and their corre-
sponding functions.
JLG SMART™ System
The machine is controlled by the JLG SMART™ System, a
24 volt, multiplex motor controller which works in conjunc-
tion with a joystick and several switches to operate all
machine functions.
Special operating characteristics of the JLG SMART™
System are noted where applicable. Special attention
should be paid to these operating characteristics, as they
may be somewhat different from those on previous JLG
machines.
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.
Ground Control Station
NOTE: Refer to the Ground Control Station for Non Propor-
tional Control machines.
Platform Control Station
1. Emergency Stop Switch
A two-position, red, mushroom-shaped emergency
stop switch functions to provide power to the plat-
form control station and also to turn off power to the
platform function controls in the event of an emer-
gency. With the power selector switch positioned to
platform, power is turned on by pulling the switch
out (on), and is turned off by pushing the switch in
(off). Turning the emergency stop switch off and
then on again will reset the smart system if a system
fault has occurred and the machine has shut down.
