Pressing the speed, acceleration button will set the speed at the faster setting.
Pressing the speed deceleration button will slow down the speed.
The controller sets the reverse speed, acceleration and deceleration proportionally and
automatically for your safety.
3.1.5 Joystick
The joystick controls the direction, speed of your power wheelchair. Push the joystick
in the direction you want to go.
Pointing the joystick away from the center position will move the power wheelchair in
the direction where the joystick is pointing.
The forward of the joystick point from the center position, the faster the vehicle will go.
Returning the joystick to its center position will reduce the speed and stop the vehicle
by automatically applying the electromagnetic brakes.
The right or left the joystick is pointing, the power wheelchair will turn the direction
sharply.
After pressing the ON/OFF buttons, allow two seconds to elapse before engaging the
joystick. This is a safety feature to prevent sudden starts.
Gentle operation of the joystick will result in smoother transitions in speed and
direction, while sharp operation of the joystick will result in drastic transitions in
direction and velocity.
3.2 Manual Mode
The motors are designed to engage the electromagnetic brakes when the power
wheelchair is not in use or when the power is OFF. It has a feature to allow the power
wheelchair in manual mode.
Manual mode: the latch mechanism has a gap from the central plane.

3.3 Electromagnetic Brakes
Your power wheelchair comes with an Electromagnetic Brakes., i.e. an automatic
magnetic disc safety brake which is also known as Fail-Safe brake.
The Electromagnetic Brakes are automatic and work when the power wheelchairs is ON
but in a steady state (i.e. Joystick is released to the center position), even when the
power wheelchair is on a slope. The Electromagnetic Brakes will also be set whenever
the power wheelchair is OFF, but the motor release levers are in the engaged (vertical)
position.
3.4 Thermal Protection
Your power wheelchair controller is equipped with a safety system called thermal
rollback. A built-in circuit monitors the temperature of the controller and motors, the
controller reduces the motor voltage and the speed of the power wheelchair. The
reduction of the speed allows the electrical components to cool down. Although your
power wheelchair will resume its normal speed when the temperature returns to a safe
level, we recommend that you turn the power off and wait for 30 seconds before
restarting to allow the components to cool down if you find that you have lost speed
suddenly.
4. Battery and Charger
4.1 Charger
The charger is an AC to DC switching-circuit designed Li-ion used charger. Best apply to
24V Li-ion battery. Pre-charge, constant current and constant voltage charging mode
designed with this charger.
Warning! Do not operate your power wheelchair in manual
mode on a slope.
