23.1 diagnostics R-Net LCD
When an error or a fault occurs in the wheelchair’s electronics, information on
it is displayed in
the control panel’s display. This information can then be used
to diagnose where the error/fault occurred and its cause.
Troubleshooting and repairs must always be performed by authorized
personnel
with good knowledge of the wheelchair’s electronics.
diagnostic screens
When the control system’s integrated protection circuits have been triggered
so that the control system can no longer operate the wheelchair, a diagnostic
screen is displayed in the control panel’s display.
This indicates a system fault, i.e. R-net has detected a problem somewhere in
the wheelchair’s electrical system.
Switch off the wheelchair and leave it off for a few minutes. Then restart the
wheelchair. If the fault persists, you must switch off the wheelchair and contact
your service contact. Write down the information displayed in plain text in the
control panel’s display and pass it on to your local authorized supplier's
service contact.
If the fault is in a module that is not currently being used, it may still be
possible to drive the wheelchair, but the diagnostic screen is displayed
occasionally.
Diagnostics should only be performed by authorized persons with sound
knowledge of the wheelchair’s electronic control system. Incorrect or
poorly performed repair works may make it dangerous to use the
wheelchair. Karma accepts no liability for any personal injury or damage to
the wheelchair and its surroundings that occurs on account of incorrect or
poorly performed repair work.
