CHAPTER 1 - OPERATION
SK77898/2
8 Control System Status indication
The battery gauge and maximum speed /profile indicator show the status of the
control system.
A number of supposedly defective control systems returned
to us are subsequently found to operate correctly. This
indicates that many reported faults are due to wheelchair
problems rather than the control system.
8.1 Battery Gauge is Steady
This indicates that all is well.
8.2 Battery Gauge Flashes Slowly
The control system 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 control
system off and on again.
8.4 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. Please follow this procedure:
• 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 cant find the problem, try using the self-help guide given in section
8.6.
• 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 service agent.
8.5 Self-Help Guide
If a system trip occurs, you can find out what has happened by counting the number
of bars on the battery gauge that are flashing.
