Troubleshooting

Troubleshooting R-net

Rnet diagnostics

When an error or a fault occurs in the wheelchair’s electronics, information on it is displayed in the con-
trol 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. Rnet has detected a problem somewhere in the wheelchair’s electric-
al system.

NB!

If the fault is in a module that is not currently being used, it may still be possible to drive the wheel-

chair, but the diagnostic screen is displayed occasionally.

Switch off the wheelchair and leave it off for a few minutes. Then restart the wheelchair. If the fault per-
sists, you must switch off the wheelchair and get in touch with your service contact. Write down the infor-
mation 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 works may make it dangerous to use the wheelchair. Permobil cannot be held responsible for any
personal injury or damage to the wheelchair and its surroundings that occurs on account of incorrect or poorly performed repair
work.
