JLG SMART System Multiplex Control Unit.
•E3 Scissor all sizes scissors function, and 3246E2 with Proportional motor control
•The JLG designed SMART System™ is a 24 Volt multiplex motor control unit installed on the electric scissor lift models 1532E3, 1932E3, 2033E3,
2046E3, 2646E3 and 2658E3.
•Emergency Stop Switch - A two-position, red, mushroom-shaped emergency stop switch functions to provide power to the platform control station
and also to turn off power to the platform function controls in the event of an emergency. 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.
•Lift Switch - The lift switch, when used in conjunction with the joystick, provides for raising and lowering the platform. Lift is activated by pressing
the lift switch and moving the joystick forward (lift up) or backward (lift down). Lift up speed is determined by the distance the joystick is moved
forward. Lift down speed is non-adjustable, and lift down is attained by moving the joystick fully backward. The lift switch is part of the enable circuit,
which provides power to the joystick and the lift function for 3 seconds when the lift switch is pressed. If the joystick is not activated within 3
seconds, the lift switch must be pressed again before activating the joystick. When the joystick is returned to the center off position, the operator
has 3 seconds to re-activate the joystick or select another function before power is removed by the enable circuit. Do not try to operate the drive,
lift, and powered deck extension functions simultaneously. If the drive, lift, and powered deck extension functions are selected simultaneously, no
function will operate. If this occurs, pause, then press only one of the function switches to activate the function.
•Drive Switch - The drive switch, when used in conjunction with the joystick, provides for driving the machine in forward or reverse. Drive is activated
by pressing the drive switch, in conjunction with the trigger switch, and moving the joystick forward (forward) or backward (reverse). Drive speed is
determined by the distance the joystick is moved forward or backward. Increased drive speed is possible when the high drive speed switch is pressed
either simultaneously with the drive switch or while operating the drive function. The drive switch is part of the enable circuit, which provides power
to the joystick and the drive function for 3 seconds when the drive switch is pressed. If the joystick is not activated within 3 seconds, the drive
switch must be pressed again before activating the joystick. When the joystick is returned to the center off position, the operator has 3 seconds to
re-activate the joystick or select another function before power is removed by the enable circuit. In addition, the posi-trac switch can be engaged
while operating the drive function to give a more evenly distributed oil flow to each drive motor.
