Troubleshooting R-net

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 dis-
play. 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 wheel-
chair’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.

NOTE!

If the fault is in a module that is not currently being used, it may still be possible to drive the wheelchair, but the diag-
nostic screen is displayed occasionally.

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 service contact.

Do not use the wheelchair until the problem has been remedied or you have received other instructions from your
service contact.

L

WARNING!

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 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.

L

CAUTION!

If any part is replaced without Permobil’s approval, the wheelchair’s warranty lapses. Permobil accepts no liability
for any loss that occurs as a a result of a component of the R-net control system being opened, adjusted or modified
without permission.
