VSI CONTROLLER
The electronic controller is what you use to operate your power chair. It takes the battery voltage and sends
it to the appropriate system. The electronic controller enables you to move the power chair, as well as
monitor battery charge, electronic controller functions, and the condition of your electrical system. The
VSI controller is an integral electronic controller. All of the electronics necessary to operate the power chair
are contained in one module. See figure 26. Typically, the VSI is mounted to one of the armrests and is
connected to the motors, batteries, and the onboard battery charger on the power base.
The controller supplied with your power chair has been pre-programmed to meet your needs. The program
is set using either a personal computer with software provided by the controller manufacturer or with a
hand-held programmer, also provided by the controller manufacturer.
WARNING! The controller program can affect speed, acceleration, deceleration, and
braking, but if it is programmed incorrectly or outside of the safe limits as determined by
your healthcare professional, it can create a dangerous situation. Only the power chair
manufacturer, an authorised representative of the manufacturer, or a trained service
technician should program the controller.

Joystick
The joystick controls the direction and speed of your
power chair. When you move the joystick from the
neutral (center) position, the electromagnetic brakes
release and allow your power chair to move. The far-
ther you push the joystick from its neutral position,
the faster your power chair moves. When you release
the joystick and allow it to return to the neutral posi-
tion, you engage the electromagnetic brakes. This
causes your power chair to decelerate and come to a
complete stop.
WARNING! If your power chair begins to move in an unexpected manner, immediately
release the joystick. Unless the joystick is damaged, this action should stop your power
chair.
Keypad
The keypad is located in front of the joystick. It contains keys necessary to operate your power chair. See
figure 27.
