Bosch Drive Unit Speed Manual Original página 292

English–3
The drive is activated as soon as you step into the pedals (ex-
cept when in start-assistance mode, see "Switching Start-as-
sistance On/Off", page English–4). The motor output de-
pends on the settings of the drive HMI.
As soon as you stop pedaling when in normal operation, or as
soon as you have reached a speed of 45 km/h, the assistance
from the eBike drive is switched off. The drive is automatically
re-activated as soon you start pedaling again and the speed is
below 45 km/h.
Options for switching off the eBike system:
– Press the On/Off button 5 of the drive HMI.
– Switch the battery pack off by its On/Off button (see bat-
tery pack operating instructions.)
– Remove the drive HMI out of its holder.
When no power output of the drive is requested for approx.
10 minutes (e. g., because the eBike is parked) and no button
of the drive HMI or operating unit is pressed, the battery pack
automatically switches off to save energy.
Indications and Settings of the Drive HMI
Power Supply of the Drive HMI
When the drive HMI is inserted in holder 4, a sufficiently
charged battery pack is inserted in the eBike and the eBike
system is switched on, power is supplied to the drive HMI via
the eBike's battery pack.
When the drive HMI is removed from holder 4, it is supplied
with power via an internal battery pack. If the internal battery
pack is low when switching on the drive HMI, "Attach to bike"
is displayed for 3 s in text indication c. Afterwards, the drive
HMI switches off again.
To recharge the internal battery pack, insert the drive HMI in-
to the holder 4 (a battery pack must be inserted in the eBike).
Switch the eBike battery pack off by its On/Off button (see
battery pack operating instructions).
The drive HMI can also be charged via USB connection. Open
protective cap 8 for this. Using a matching USB cable, con-
nect the USB port 7 of the drive HMI to a commercially availa-
ble USB charger or to the USB port of a computer; (5 V charg-
ing voltage; max. 500 mA charging current). "USB
connected" is displayed in text indication c of the drive HMI.
Switching the drive HMI On/Off
To switch on the drive HMI, briefly press the On/Off button 5.
When the internal battery pack is sufficiently charged, the
drive HMI can also be switched on when not inserted in the
holder.
To switch off the drive HMI, press the On/Off button 5.
When the drive HMI is not inserted in the holder and no button
is pressed, it automatically switches off after 1 min to save en-
ergy.

Battery Charge-control Indicator
The battery-pack charge-control indicator f indicates the
charge condition of the eBike's battery pack, and not the
charge condition of the drive HMI's internal battery pack. The
charge condition of the eBike's battery pack can also be read
from the battery pack's LEDs.
On indicator f, each bar of the battery pack symbol is equiva-
lent to a capacity of approx. 20 %:
100 % to 80 % capacity
20 % to 5 % capacity; the battery pack should be
recharged.
Less than 5 % capacity; drive assistance is no long-
er possible. The LEDs of the charge-control indica-
tor on the battery pack go out.
When the eBike lighting is powered via the battery pack
(country-specific), the capacity upon first indication of the
empty battery pack symbol will be sufficient for approx.
2 hours of lighting. When the symbol begins to flash, the light-
ing will continue to operate only for a short period.
When the drive HMI is removed from holder 4, the last indicat-
ed battery pack charge condition is stored.
Setting the Assistance Level
The level of assistance of the eBike drive when pedaling can
be adjusted via the drive HMI. The assistance level can be
changed anytime, even during riding.
Note: For individual versions, it is possible that the the assis-
tance level is pre-set and cannot be changed. It is also possi-
ble that less assistance levels are available for selection than
listed here.
The following assistance levels (max.) are available:
– "OFF": The drive is switched off, the eBike can be operated
as a normal bicycle through pedaling.
– "ECO": Effective assistance at maximum efficiency for
maximum cruising range
– "TOUR": Uniform assistance, for touring with long cruising
range
– "SPORT": Powerful assistance for sportive riding off road
as well as for urban traffic
– "TURBO": Maximum assistance, supporting highest ca-
dence for sportive riding
To increase the assistance level, press the "+" button 13 on
the operating unit until the desired assistance level is dis-
played in indicator b; to decrease the assistance level, press
the " –" button 12.
The requested motor output is displayed in indicator a. The
maximum motor output depends on the selected assistance
level.
