CONTROLLER INFORMATION
The controller supplied with your power chair has been preprogrammed by the manufacturer to meet the needs of the end
user. 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 programmed incorrectly or outside of the safe limits as determined by your healthcare
professional, 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.
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. Also, it may be used to control some optional
systems such as power elevating seats and lights.

Figure 22. VSI Controller
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 22.
The VSI consists of:
1. joystick
2. keypad (see figure 23)
3. off-board charger/programming socket
4. actuator connector (optional)
5. controller connector
Typically, the VSI is mounted to one of the armrests
and is connected to the motors and batteries on
the power base.
Joystick
The joystick controls the direction and speed of your power chair. When you move the joystick from the neutral (centre)
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, 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 23.
