VSI CONTROLLER
The electronic controller is what you use to operate your Go-Chair. It takes the battery voltage and sends it to the appropriate system. The electronic controller enables you to move the Go-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 Go-Chair are contained in one module. See figure 22. Typically, the VSI is mounted to one of the armrests and is connected to the motors and batteries on the power base.
The VSI consists of:
1.joystick
2.keypad
3.off-board charger socket
4.controller connector
Joystick
The joystick controls the direction and speed of your Go-Chair. When you move the joystick from the neutral (center) position, the electromagnetic brakes release and allow your Go-Chair to move. The farther you push the joystick from its neutral position, the faster your Go-Chair moves. When you release the joystick and allow it to return to the neutral position, you engage the electromagnetic brakes. This causes your Go-Chair to decelerate and come to a complete stop.
WARNING! If your Go-Chair begins to move in an unexpected manner, imme- diately release the joystick. Unless the joystick is damaged, this action should stop your Go-Chair.
Keypad
The keypad is located in front of the joystick. It contains keys necessary to operate your Go-Chair. See figure 23.
