FAULT DIAGNOSIS
Faults with the main speed controller are rare. Most faults on powered wheelchair are
associated with wiring or bad connections due to poor maintenance or incorrect installation
of connectors when assembling the wheelchair after transporting the wheelchair. If your
wheelchair fails to operate refer to the status fault codes on the following page for reference.
If in doubt, consult the dealer from whom you purchased your wheelchair.

SPEED CONTROLLER SETTINGS
Performance adjustments should not be made to the joystick which could
compromise the integrity of the speed controls and put the operator in serious
danger. Performance adjustments should only be made by an authorized
wheelchair technician fully trained and conversant with the programming and
capabilities of the wheelchair.
Incorrect settings could cause injury to the wheelchair operator and/or to
bystanders or damage to the wheelchair and/or surrounding property. If in
doubt, consult your authorized dealer.
FAULT DIAGNOSIS
The speed controller system incorporates a sophisticated microprocessor which continually
monitors the wheelchair systems to ensure safe and reliable operation. Safety conditions
monitored by the speed control are listed below:
Speed control system integrity
Internal voltages and circuits
Motor voltages and circuits
Freewheel speed limiting downhill
Battery voltage
When the battery voltage is low, the 'status' indicator light situated on power switch will
flash slowly as a warning for you to recharge your batteries. If the 'speed controller' detects a
fault, the light will flash more rapidly, with the number of flashes indicating the nature of the
fault. If your wheelchair is switched 'on' but not operated for a set period of time (5 minutes
approximately) the speed controller system will automatically turn itself 'off' to conserve
valuable battery energy. This fault can be cleared when you power off then power back on.
