Section 3
A joystick trip is indicated. Make sure that the joystick is in the center position before switching on the
control system. Check that the batteries are fully charged and in good condition, examine the joystick
for damage. This fault can also be caused by a joystick that fails to center itself due to being dirty,
bent or broken. If this is the case, replace the joystick module.
Note: If replacing the joystick does not resolve the issue, replace the cable connecting the joystick to
the controller.
Seven Bars - Possible Joystick Trip
The onboard batteries are being charged with the off-board charger. You will not be able to drive the
wheelchar until the charger is disconnected. You will have to reset the control system by switching
off the power and then powering up again. The On-Board charger has no indication that the chair
is charging, and the chair will not move until complete. If the condition still exists after the charger
has been diconnected, and the chair has been switched off and then powered up again, the Joystick
module may be defective.
