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 26. Typically, the VSI is mounted to one of the armrests and is connected to the motors, batteries, and the onboard battery charger on the power base.

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, 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 authorised 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.

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 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 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 27.
