Troubleshooting

Error signals - Battery voltage indicator

Every time the wheelchair is started up, a check is performed on parts of the wheelchair’s electronics. If
any faults have arisen in these parts, this is shown on the control panel’s battery voltage indicator by one
or more blinking lights.

Constant light

Everything is in order. How many lights are lit, depends upon how much voltage there is in the batteries.
With fully charged batteries, all lights are lit.

Slowly blinking red lights

The batteries need to be charged immediately.

Rapidly blinking, 1 - 10 lights

Error signals, an error has arisen and the wheelchair can not be driven.

Error signals

The number of blinking lights indicate what the problem could be.

–  Note the number of blinking lights.

–  Turn off the wheelchair.

–  Turn the wheelchair back on again.

–  If the error persists, count the number of blinking lights, check possible causes and solutions in the

table on the adjoining page.

NB!

Possible error signals on the battery voltage indicator are not displayed while the wheelchair is

being driven, they only first appear the next time the wheelchair is restarted.

Warning!

The remedying of errors that are indicated via the battery voltage indicator must be performed

by a person with sufficient expertise to be able to perform such in a professional manner. Always contact
an authorized serviceman when in doubt.
