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.
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 16.
The VSI consists of:
1. joystick
2. keypad (see figure 17)
3. off-board charger/programming socket
4. actuator connector
(optional)
5. controller connector
6. 3-pin charger inhibit

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.
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 further 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 17.
On/Off Key
The on/off key turns the VSI on and off. See figure 17.
WARNING! Unless faced with an emergency situation, do not use the on/off key to stop the chair.
This will cause the power chair to stop abruptly.
WARNING! Always turn the power off when you are stationary to prevent unexpected movement.
