4.5 Charging process
During the charging process the sensors on the push rims are calibrated. For this reason
no pressure or tension must be exerted on the push rims [4] during the charging process.
Therefore, ensure with every charging process that the push rims are free from any load.
During charging, if the push rims are accidentally subjected to a load and the sensor
alignment adjustment has been affected, please proceed as follows:
•
Ensure that the push rims [4] are not subjected to any load, pressure or tension.
•
Charge again for about 10 minutes; this will readjust the sensors.
•
Finish the charging process.
The following describes how the charging process should be carried out on the twion
wheels.
•
The charger socket of the battery is integrated in the on/off button [2] on the twion
wheel.
•
Insert the plug of the battery charger [9] into the charger socket [2]. The connection
is locked automatically by a magnetic closure.
•
Then insert the power cable of the charger into a socket.
•
Depending on the residual capacity the batteries have, one or more LEDs on the wheel
light up, on the battery charger the LED display [10] flashes green
(see also chapter 5.2).
•
If the battery is fully charged, all five LEDs on the wheel illuminate and on the battery
charger the LED display [10] illuminates a continuous green.
•
Disconnect the mains plug of the battery charger from the mains socket.
•
Only now remove the plug of the battery charger [9] out of the charger socket [2].
Ensure that the charger plugs [9] and the sockets in the on/off but-
ton [2] of the twion wheel are clean and that there are no metallic
particles. If you detect such particles, use a dry and clean cloth to
remove them.
If the twion wheels are not used for a prolonged period (more than
one day), the battery charger needs to be disconnected first from
the mains socket and then from the wheel (battery). Before using
your twion, always check the charge status of the batteries. These
should be fully charged at the start of your trip.
If a fault occurs when charging the wheels, this is shown by the LED
display [1] and acoustic signals (see chapter 5.3).
If the twion wheels are on the wheelchair for charging, before star-
ting the charging process, switch off both wheels and secure the
wheelchair using its parking brakes against inadvertently rolling
away.
The magnetic plugs of the charger must not come near the sensor on
the wheel because it could affect the calibration of the sensor.
During the charging processing no pressure or tension must be
exerted on the push rims [4] because this can cause the charging
process to stop.
