5.3 Acoustic error messages
The following table describes the errors occurring most frequently and are mainly due to faulty handling of the e-motion wheel. They mean:
Short signal tone, duration approx. 0.2 seconds
Long signal tone, duration approx. 0.8 seconds

Error description What to do
every 8 seconds
Overvoltage in the battery pack; a forced shut-
down is immediately pending.
The error occurs especially when driving down
slopes with fully charged battery pack. Drive at a
slower speed.
every 10 seconds
Overvoltage of the battery pack, the drive was
shut down by force.
The error occurs especially when driving down
slopes with fully charged battery pack. Drive at a
slower speed.
every 10 seconds
The charging process was terminated because
the ambient temperature
is below 0 °C
or
above 0 °C.
Charge the battery packs only at temperatures
above 0 °C
and
below 40 °C.
every 5 minutes
Voltage of the battery pack < 20 % remaining
capacity
Charge the battery pack as soon as possible.
every 60 seconds
Undervoltage of the battery pack (< 10 %
remaining capacity), a forced shut-down is
immediately pending.
Charge the battery pack immediately.
every 10 seconds
Undervoltage of the battery pack (< 5 %
remaining capacity), a forced shut-down is
immediately pending.
Complete a ride down a slope. Charge the battery
pack immediately.
every 5 seconds
The charger plug is inserted in the charger
socket but no charge current is flowing.
Check the operational readiness of the charger.
Possible defect on the charger or wheel; repair is
then required.
Each time when
switching on the
e-motion 1 time
The battery pack has less than 60 % capacity
of a new battery.
The achievable range is significantly reduced.
Replace the battery pack against a new one.
every 10 seconds
The battery pack was charged longer than 12
hours but is not completely charged.
The charger is defective is both battery packs are
charged at the same time and the error messages
is indicated for both battery packs.
If both battery packs are charged at the same
time and the error message is indicated for only
one battery pack, this battery pack is defective.
Repair is required in both cases.
every 10 seconds
The voltage in the battery pack is no longer
sufficient for operation, the drive was shut
down by force.
Charge the battery pack immediately.
