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 your power chair, as well as monitor battery
charge, electronic controller functions, and the condition of your electrical system. Also, the VSI controller may be
used to control some optional systems such as power elevating seats and lights. 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 33. Typically, the VSI controller is mounted to one of the armrests and is connected to the motors, batteries,
and the onboard charger at the power base (i.e., at the electronics tray or a battery box).
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. 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.
The VSI consists of:
1. joystick
2. keypad
3. off-board charger/programming socket
4. actuator connector (optional)
5. controller connector
6. 3-pin charger inhibit connector
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 farther 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 position, the electromagnetic
brakes engage and the power chair comes 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 34.
