Internal fault, the system is defective. Contact your specialist dealer.
If any fault indications other than those listed are indicated, there is a serious system malfunction. In this case
the twion wheel cannot be used and must be sent to Ulrich Alber GmbH via your specialist dealer for testing.
6. Automatic shut-down
If a wheel that has been switched off does not move for longer than 15 minutes, it is automatically turned off to save energy.
7. Replacing the fuse
As with all electrical and electronic devices, your twion is equipped with a fuse system. In the event of a defect, the fuse reacts and
thereby protects the electronics from sustained and expensive damage.
The fuse of the twion wheel is located within the electronics housed in the wheel hub. Any fuse replacement required, combined with a full
diagnosis of the entire electronic system, may only be performed by Alber.
