Connectors: Make sure that all connectors are securely mated.
Cables: Check the condition of all cables and connectors for damage.
Joystick gaiter: Check the thin rubber gaiter or boot, around the base of the joystick shaft, for damage or splitting. Check
visually only, do not handle the gaiter.
Mounting: Make sure that all the components of the controller are securely mounted. Do not overtighten any securing
screws.
7.3 Servicing
To ensure continued satisfactory service, we suggest you have your wheelchair and controller inspected by your service agent
after a period of 1 year from commencement of service. Contact your service agent for details when the inspection is due.
8 Control System Status Indication
The battery gauge and maximum speed /profile indicator show the status of the controller.
A number of supposedly defective controllers returned to us are subsequently found to operate
correctly. This indicates that many reported faults are due to wheelchair problems rather than the
controller.
8.1 Battery Gauge is Steady
This indicates that all is well.
8.2 First LED flashing slowly
The controller is functioning correctly, but you should charge the battery as soon as possible.
8.3 Battery Gauge Steps Up
The wheelchair batteries are being charged. You will not be able to drive the wheelchair until the charger is disconnected and
you have switched the controller off and on again.
8.4 All 5 LEDs in the battery display are flashing
The controller safety circuits have operated and the controller has been prevented from moving the wheelchair.
This indicates a system trip, i.e. the newVSI has detected a problem somewhere in the wheelchair’s electrical system. Please
follow this procedure:
•
Switch off the controller.
•
Make sure that all connectors on the wheelchair and the controller are mated securely.
•
Check the condition of the battery.
•
If you can’t find the problem, try using the self-help guide given in section 8.5.
•
Switch on the controller again and try to drive the wheelchair. If the safety circuits operate again, switch off and do not try
to use the wheelchair.
Contact your service agent.
8.5 Self-Help Guide
If a system trip occurs, you can find out what has happened by counting the number of flashes of the battery gauge.
