8 Troubleshooting using the VR2 Hand Control
Always consult your Sunrise Medical authorised dealer when a
diagnostic fault has appeared on your hand control.
The battery gauge and maximum speed/profile indicator show the
status of the control system.
Battery Gauge is steady - This indicates that everything is OK.
Battery Gauge flashes slowly - The control system is functioning
correctly but the batteries need charging as soon as possible.
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 control system off and on
again.
Battery Gauge flashes rapidly (even with the joystick released)
The control system safety circuits have operated and the control
system has been prevented from moving the wheelchair.
This indicates a system trip. i.e. the VR2 has detected a problem
somewhere in the wheelchairs electrical system.
•
Switch off the control system
•
Make sure that all connectors on the wheelchair and the control
system are mated securely.
•
Check the condition of the battery
•
If you can't find the problem, try the self help guide given below
•
Switch on the control system 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 Sunrise Medical Authorised Dealer.
Self help guide
If a system trip occurs you can find out what has happened by counting
