Figure 26. VSI Controller

VII. OPERATION

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 electronic controller is an integral electronic controller. All of the electronics necessary to operate the power chair

are contained in one module. See figure 26. Typically, the VSI is mounted to one of the armrests and is connected to the

motors, batteries, and the onboard 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 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 program-

mer, also provided by the controller manufacturer.

WARNING! The controller program can affect speed, acceleration, deceleration, and braking. 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 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 electromagnetic brakes

release and allow your power chair to move. The far-

ther 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 com-

plete 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 27.
