Troubleshooting
R-net diagnostics
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 competent personnel with good knowledge
of the wheelchair’s electronics. More information on troubleshooting and remedies can be found in the
Service Manual for this wheelchair model.
Diagnostic screens
Current diagnostic screen
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.
NB!
If the fault is in a module that is not currently being used, it will still be possible to drive the
wheelchair, but the diagnostic screen will be displayed occasionally.
Switch the wheelchair off 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 service contact.
Do not use the wheelchair until the problem has been remedied or you have received other instructions
from your service contact.
Diagnostics should only be performed by persons with sound knowledge of the wheelchair’s electronic control system. Incorrect
or poorly performed repair work may make it dangerous to use the wheelchair. Permobil accepts no liability for any personal
injury or damage to the wheelchair and its surroundings that may occur on account of incorrect or poorly performed repair work.
