VII. OPERATION
GC CONTROLLER SYSTEM
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 GC is a modular electronic controller system. The system consists of a joystick module and a power module. See
figure 22. Typically, the joystick module is mounted to one of the armrests and is connected to a power module located on
the power base.
The controller system 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 GC Controller system consists of:
1. joystick
2. control panel
3. joystick module
4. power module
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
farther you push the joystick from its neutral posi-
tion, the faster your power chair moves. When you
release the joystick and allow it to return to the neu-
tral 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.
NOTE: If you move the joystick before or just
after you switch on the power, the battery con-
dition meter will ripple side-to-side and the
power chair will not move. If you do not re-
lease the joystick within five seconds, the power
chair will not move until you turn the con-
troller off and on again.
