E3 Scissor Platform
Control Measures

2
2.6.5 Duplicate controls: Location, accessibility, protection and selection
Duplicate controls for all powered functions that are necessary to retrieve the platform in an emergency shall be provided at the
base or ground level, and shall override control devices situated on the work platform.
Extracts from ASNZS 1418-10 2011
2.6.4 Work platform controls: Location, accessibility, protection
Control devices shall be situated on the work platform and shall be readily accessible to the operator. Platform control boxes not permanently
attached shall have their normal location and orientation clearly marked on the platform and the control box.
When released, all control devices shall automatically return to the ‘off’ or ‘neutral’ position, if used to control any movement of the MEWP.
All control devices shall be protected against activation other than that initiated by the operator.
NOTE: A separate control, which has to be continuously activated by the operator in order for any motion to take place, meets this
requirement.
Where a separate control is integral with a motion control, the control shall be mechanically protected against inadvertent actuation.
A guard shall be provided and located at least 50 mm above the highest point of the controls.
2.6.10 Overriding emergency system
Overriding of the platform emergency stop control and load-sensing system is allowed for rescuing a trapped or incapacitated operator on the
platform. Overriding is permitted only by the use of a safety device that is independent from the selection control device. The safety device shall be
operated by hold to run controls.
The overriding of the load-sensing system shall allow motion of the platform sufficient to rescue the operator. Features shall be provided to protect
against misuse of the overriding system.

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.
