For connecng the wires with the blade connectors
insert each wire (without stripping) of the Sx2 Tuning-
Dongle cable into the one-sided openings of the blade
connectors (2).
The related wires of the speedsensor and the + wire
of the control unit Intuvia (6) are inserted into the
through-opening of the blade connectors. Now press
down with your hand the blade connectors (2) rmly.
Compress with a pliers as possible parallel.
Once the terminals are crimped, the speedsensor plug
(1) should be reconnected to the engine and the chain
applied to the chain wheel.
Now the pedal has to be turned up slowly by hand and
the speedometer should be checked for funcon. If the
speed is shown on the display repeat the procedure
with a plugged Sx2 Tuning-Dongle into stereo jack so-
cket (5). Unl the switch point is reached, the shown
speed jumps to the half speed.
Aer that, assemble the hood and the e-bike together.
The cablekit should be mounted in a way to protect
the connectors from splashing water and mechanical
damage.

FAQ
(further Help you can nd at support.maintronic.de)
I have done the installaon exactly like shown, but the
switchoverpoint is not percepble?
ANSWER:
Distance and Posion of the magnet aecng the
switching me of the speed sensor. The shorter the
switching me, the sooner is the switchoverpoint and
conversely. Try to turn up the pedal by hand while the
engine is turned o ll 50km/h and watch the speedo-
meter.
If the switchoverpoint is below 12km/h or over 28km/h
or not at all please contact your specialist dealer or the
Sx2 Support >>> [e-mail]
How can I inuence the switchoverpoint?
ANSWER:
If the speed sensor with the magnet is moved into the
axis direcon, the switching speed increase.
Conversely the speed sensor with the magnet is moved
outside to the re direcon, the switching me is shor-
ter and the switching speed is lower.
Manual >>> support.maintronic.de.
Is the cablekit connected correctly?
ANSWER:
Poor contacts may arise fail pulses with the Sx2 Tuning-
Dongle which causing the error 102. Check the ght-
ness of the Sx2 Tuning-Dongle and its contacts.
(Picture with stereo jack socket and measurement de-
vice)
For a further diagnose a bare 3,5mm stereo jack instead
of the Sx2 Tuning-Dongle are plugged. The measure-
ments must be +5V stable between ground(peak) to
ring, the magnet may not stay over the speedsensor.

For connecng the wires with the blade connectors
insert each wire (without stripping) of the Sx2 Tuning-
Dongle cable into the one-sided openings of the blade
connectors (2).
The related wires of the speedsensor and the + wire
of the control unit Intuvia (6) are inserted into the
through-opening of the blade connectors. Now press
down with your hand the blade connectors (2) rmly.
Compress with a pliers as possible parallel.
Once the terminals are crimped, the speedsensor plug
(1) should be reconnected to the engine and the chain
applied to the chain wheel.
Now the pedal has to be turned up slowly by hand and
the speedometer should be checked for funcon. If the
speed is shown on the display repeat the procedure
with a plugged Sx2 Tuning-Dongle into stereo jack so-
cket (5). Unl the switch point is reached, the shown
speed jumps to the half speed.
Aer that, assemble the hood and the e-bike together.
The cablekit should be mounted in a way to protect
the connectors from splashing water and mechanical
damage.

connected cablekit.
FAQ
(further Help you can nd at support.maintronic.de)
I have done the installaon exactly like shown, but the
switchoverpoint is not percepble?
ANSWER:
Distance and Posion of the magnet aecng the
switching me of the speed sensor. The shorter the
switching me, the sooner is the switchoverpoint and
conversely. Try to turn up the pedal by hand while the
engine is turned o ll 50km/h and watch the speedo-
meter.
If the switchoverpoint is below 12km/h or over 28km/h
or not at all please contact your specialist dealer or the
Sx2 Support >>> [email protected]
How can I inuence the switchoverpoint?
ANSWER:
If the speed sensor with the magnet is moved into the
axis direcon, the switching speed increase.
Conversely the speed sensor with the magnet is moved
outside to the re direcon, the switching me is shor-
ter and the switching speed is lower.
Manual >>> support.maintronic.de.
Is the cablekit connected correctly?
ANSWER:
Poor contacts may arise fail pulses with the Sx2 Tuning-
Dongle which causing the error 102. Check the ght-
ness of the Sx2 Tuning-Dongle and its contacts.
(Picture with stereo jack socket and measurement de-
vice)
For a further diagnose a bare 3,5mm stereo jack instead
of the Sx2 Tuning-Dongle are plugged. The measure-
ments must be +5V stable between ground(peak) to
ring, the magnet may not stay over the speedsensor.

Fehleranalyse
If the cablekit is connected but the dongle has no operaon,
it´s possible the cablekit does not have the right connecon or
the voltage is not enough.
To make sure the connecon is ok, the present voltage and cur-
rent can be checked with a measurement device.
Please note !!! The magnet of the speedsensor may not ex-
ceed over the Sensor during the measurement.
Voltage measurement:
Therefor is the best way to take a 3.5mm stereo jack with two
male connectors and measure according to the below connec-
on diagram.
Between the p and the front ring has to be +5VDC. The p of
the jack is Ground.

If your eBike with Bosch engine has already light ins-
talled and the light funcon on the control computer
is enabled, one of the two exisng light cables need to
be connected to our Sx2KB-Plus power switch cablekit.
To use the opon, the Sx2 Tuning-Dongle with the light
switch on and o.
For this purpose, the insulaon need to be removed
about 10-15 cm behind the plug from one of the two
light cables.
Please take care not to damage the single wired.
The insulaon of the two wires has to be removed ap-
prox. 1 cm.
Connect the twisted wires to the terminals on the termi-
nal block (terminal designaon 1).
Please observe polarity:
red = posive pole; black = minus;
Either the front or rear light can be connected. It is only
important to connect the light cable to the input with
the (1) (to the right of the speed sensor connecon (S).
To connect cables to the terminal block, use a screwdri-
ver to push the white lever, as shown in the picture
below, to the le in the direcon of the opening and
insert a stripped cable into the opening. Then push the
lever to the right again. Check cable for ghtness.
Both wires (+ red and - black) must be connected. If the
cable for the light is connected to the terminal block
(terminal designaon 1), the speed sensor with the in-
sulaon displacement terminal can be connected accor-
ding to the operang instrucons.
Finally, put the plug back into the engine compartment.
Kink the cables and
twist the wires.
