VSI ELECTRONIC CONTROLLER

The electronic controller is what you use to operate your power chair. 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 is an integral electronic controller. All of the electronics necessary to operate the power chair are contained in one module. See figure 30. Typically, the VSI is mounted to one of the armrests and is connected to the motors, batteries, and the onboard battery charger at the power base. The VSI may be used to control some optional systems such as power elevating seats and lights.

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 authorized 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. 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 electro-
magnetic 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	Figure 30. VSI Controller
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 31.
