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 23. Typically, the VSI is mounted to one of the armrests and is
connected to the motors, batteries, and the onboard charger on the power base.
The controller supplied with your power chair has been pre-programmed to meet the needs of the end user.
The program is set using either a personal computer with software provided bey the controller manufac-
turer or with a hand-held programmer, also provided by the controller manufacturer.
WARNING! The controller program can affect speed, acceleration, deceleration, and brak-
ing. 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 manu-
facturer, an authorised representative of the manufacturer, or a trained service techni-
cian should program the controller.
The VSI consists of:
1. joystick
2. keypad
3. off-board charger/programming socket
4. acutator connector
5. controller connector
6. charger inhibit connector
Joystick
The joystick controls the direction and speed
of your power chair. When you move the joy-
stick from the neutral (center) position, the elec-
tromagnetic 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 joy-
stick 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 24.
