1. General Information
!
With actively powered wheelchairs, only the optimal adjustment allows for greatest possible mobility of the user. e-motion
offers many options for tuning according to the individual demand. The following functions and properties permit you, individually or in combination, to make individual adjustments for the wheelchair driver:
Variable attachment of the wheels
The fully integrated placement of the motors and functional elements in the wheel hubs permit realizing variable wheel
positions depending on the wheelchair frame. For example, a greater angle of seat can be offered when first mobilizing the
patient. On the other hand, different body proportions can be compensated for; this is important for an economic drive movement and good seating.
Examples:
2
Large angle of seat -
for mobilization
You can take advantage of the entire bandwidth of the "active" wheelchair adaptation and are still free to choose the suitable
wheelchair model. The following sections shall help you configure the optimal adjustment of the e-motion using an incremental approach.
First read the operating instructions
Familiarize yourself with the functional elements and safety instructions!

2. Adjustment options
You must insert the battery packs in the wheel hubs before you can begin programming the e-motion
wheels. Please follow the e-motion operating instructions included in the information and comments of
Chapter 4.6.
Overview
[0] = Button 0
[1] = Button 1
[2] = Button 2
[3] = RESET button
[4] = Info button
[5] = Magnetic key
It does not matter for programming to which power stage (1 or 2) the wheels are currently set.

2.1 Adjusting the remote control to the e-motion wheels
To be able to proceed with programming, the remote control must first be configured for the two emotion wheels. Perform the following steps in sequence.
• First, switch off the two e-motion wheels at the wheel hubs (see operating instructions, chapter 2.4).
• Switch on the remote control by pressing the Info button once [4]. All display elements will light up
for one second.
• Press buttons [0] and [2] and hold them down. A countdown (from 5 to 0) will be displayed.
• Hold down buttons [0] and [2] until the countdown from 5 to 0 has finished and then release them
for one second.
• Then press down buttons [0] and [2] at the same time again. A countdown (from 4 to 0) will be dis-
played this time.
• Hold down buttons [0] and [2] until the countdown from 4 to 0 has finished and then release them.
• Five flashing battery bars will now be flashing on the right side of the display.
• Switch on the right e-motion wheel at its wheel hub. After a short signal has sounded, press button
[1].
• Five battery bars will now be flashing on the left side of the display.
• Switch on the left e-motion wheel at its wheel hub. After a short signal has sounded, press button
[1].
The remote control and the e-motion wheels will now be synchronised. In the display you will see the
numbers 1 and 0 rapidly interchanging. Once the synchronisation is complete, only the number 1 will
be displayed. Now complete the following steps to set both e-motion wheels to the same drive parameters (factory setting with remote control):
• Take a sharp object and use it to press the RESET button [3] for five seconds. A magnetic key is not
required for this.
• A short acoustic signal tells you the adjustment was successful.
• To conclude the process, switch off the e-motion wheels by pressing the [0] button on your remote
control.
• Now switch the e-motion wheels back on by pressing the Info button [4].
Both wheels are now set to the factory setting (with remote control) and can be set to
the respective user driving parameters again (see chapter 2.2).
2.2 Programming the e-motion wheels with the remote control
!!!
• Switch on the remote control by pushing the Info button [1]. All indicators now appear briefly in the
display.
• Switch on the two e-motion wheels (see operating instructions, Chapter 2.3).
• Insert the magnetic key into the recess on the bottom of the remote control.
5
• The first parameter ("0"), its current programming status (symbolized by the bar) and the tool symbol
(as visual verification for the activated programming mode) are shown in the display.
• Push the Info button [4] if the respectively shown parameter shall not be changed.
Programming advances to the next parameter [1, 2, 3, ...] each time you press the Info button [4].
4
• On the remote control push the following if the parameter shown shall be changed:
- button [1] to reduce the parameter (symbolized by the reduction
of the associated bar display)
- button [2] to enlarge the parameter (symbolized by the enlargement
of the associated bar display)
• Each push on the buttons [1] or [2] decreases or increases the parameter to be set by one increment
each. The respective current status is symbolized in the associated bar display.
• Push the button [0] if you want to accept the selected value. Now push the Info button [4] to reach
the next parameter.
• Push the Info button [4] only to get to the next parameter if you do not want to accept the value
and leave the parameter unchanged.
• You can close the programming mode after you have set all parameters according to the preferences
of the wheelchair driver. Pull the magnetic key from the bottom of the remote control [5] to complete
the process.
• The programming mode is closed automatically if no button is pushed for more than 15 seconds.
The programming mode can be closed at any time and regardless of the parameter
shown in the display. Please remember that changed parameter settings are only
accepted if the button "0" was pushed.
The "Exclamation mark" symbol appears in the display when a parameter value is
changed. It only goes off after the set value was accepted or the next parameter was
selected.
We recommend changing only one parameter if you program an e-motion wheel for
the first time. This helps you to better learn the effects of the change on the driving behaviour.
Always perform a test run with the e-motion first after you have changed parameters and before handing
the wheelchair to the wheelchair driver. Become familiar thereby with the changed parameter values and
their effects on the driving behaviour and verify their correct setting at the same time.
Pay special attention to the driving behaviour when changing parameters 5 and 8 (follow-up time in
power stage 1 or 2). The motors of the e-motion wheels may run after longer than you may expect.
Perform test drives only in a safe area free from obstacles and traffic.
Once all parameters have been set correctly and as desired, the wheelchair driver should perform a test
drive according to your instructions. This will give the driver the opportunity to become familiar with the
new driving behaviour; you can modify undesired parameter values once more, if necessary.
3
2.3 Parameter Reset
All parameters can be set back to the original factory settings at any time.
Take a sharp object and use it to press the RESET button [3] for five seconds. After a short signal has
sounded switch off the e-motion wheels by pressing the [0] button on your remote control.
Now switch the e-motion wheels back on by pressing the Info button [4].
The e-motion wheels have now gone back to their original parameters (see chapter 2.6).
2.4 Parameter sets
The values of 10 parameters can be changed in 5 increments each and thus adapted to the individual
preferences of the wheelchair driver. The respectively set parameter value is thereby always indicated in
the display of the remote control.
Example:
The current parameter (in the adjacent example "0" = sensitivity of the push rim) is indicated in the
center of the display.
Each of the parameter values set (level 1 to level 5) is shown at the left or right side of the display via
the bar indicator (1 to 5 bars). The following applies hereby:
5
• For the parameter "0", the symbol is shown at the left side of the display (for the e-motion wheel
mounted to the left side of the wheelchair).
• For the parameter "1", the symbol is shown at the right side of the display (for the e-motion wheel
mounted to the right side of the wheelchair).
• With parameters "2" to "9", the bar symbols appear on the left and right side of the display since
these parameters affect both wheels.

Sensitivity
The following diagram illustrates the force to be applied in relationship to the sensor setting of the push rim.
They mean:
Minimum effort: Parameter value 1 at parameter 0 respectively 1, see chapter 2.6
Medium effort: Parameter value 3 at parameter 0 respectively 1, see chapter 2.6
Maximum effort: Parameter value 5 at parameter 0 respectively 1, see chapter 2.6
Motor assistance (Nm) - Torque

Force applied at the push rim in Newton
With a person weighing approx. 80 kg, only roughly 500 grams (5 Newton) of force introduction is required on level ground to begin moving from the standstill state. Subsequently, even less force is required to remain in a continuous forward or backward movement.
The individual choice of the sensor setting also facilitates the support of therapeutic measures. The wheelchair driver can be gradually
guided to use a higher force to be exerted by him. This happens by reducing the sensor sensitivity at regular intervals.
Starting and follow-up time
Power assistance in
percent of the maximum
output
Time
Start Follow-up
Start:
Time between moving the push rim until reaching the desired motor output in seconds.
The longer the time period, the more sluggish the motor response to the impulse from the push rims. Higher settings are ideal for patients
who are generally strong but restricted in the coordination of their arms (e.g. spastics).
Power assistance:
What is the max. applied percentage of the possible motor output?
Max. torque: 30 Nm (=100 %).
Higher assistance = lower range
Lower assistance = higher range
Follow-up:
How long does the motor "run after" (follow-up) after the push rim was operated and released again?
Obstacles (e.g. curbs) can be overcome more easily, significantly fewer pushes are required when driving uphill.

2.7 Adjustment activities on the wheel
2.7.1 Setting the sensitivity of the push rim
• Push the On/Off button [6] on the e-motion wheel for approximately 5 seconds to activate the
service-mode.
• 3 signal tones will sound if the service mode is active and the green LED [7] comes on.
• Push the On/Off button [6] on the e-motion wheel again for approximately 5 seconds.
• 1 signal tone sounds after 5 seconds.
• Displace the push rim to set the desired sensitivity value (see table, Chapter 2.6).
6
Displacement in direction A increases the value to be set,
displacement in direction B reduces it.
• The LEDs indicate the set value as follows:
20 % sensitivity LED 7 comes on
40 % sensitivity: LED 8 comes on
60 % sensitivity: LED 9 comes on
80 % sensitivity: LED 10 comes on
100 % sensitivity: LED 11 comes on
• Once you have set the desired value, push the On/Off button [6] on the e-motion wheel again for
approximately 5 seconds.
• A signal tone sounds after 5 seconds and the programmed value is stored in the wheel.
• This completes the programming process and the wheel is switched off automatically.
9
With each of the steps described in Chapter 2.7.1, the wheel sensor transmits pulses to the wheel electronics.
The entire programming process is terminated if the wheel electronics does not
receive a pulse over a period of 30 seconds (regardless at which point in the process
you are currently positioned).
The programming process must then be started all over again.

3. Replacing the battery of the remote control
Under normal use, the battery must be replaced after approx. 5 years. Proceed as follows:
• Loosen and remove the six screws accessible at the bottom of the housing.
• Remove the used up battery.
• Insert a new battery in the battery compartment in the top part of the housing (pay attention to cor-
rect polarity!).
• Make sure that the string, as shown in the graphic illustration, is routed around the pin of the top
section of the housing.
• Join the top and bottom section of the housing again. Make sure that the rubber seal has been cor-
rectly inserted between the two sections of the housing.
• Screw both halves of the housing together with the six screws accessible at the bottom of the hous-
ing.
(Attention: Tighten the screws hand-tight!)
• Dispose of the used up batteries properly according to the applicable regulations of your country.
10
-
You will come into contact with electronic components of the printed circuit
board when replacing the battery. Therefore pay attention to the ESD precautions
during battery replacement.
Use only batteries of the type CR123A (lithium battery, 3 Volt, at least
1500 mAh) to operate the remote control.
Using other batteries may damage the electronics.
4. Starting to drive
!
Make sure that the anti-tippers are installed on the wheelchair before beginning to drive; this is required
for safety reasons.
To start, choose a level floor with smooth surface such as stone, PVC or parquet and preferably no carpet
floor. This is necessary because the fibers of a carpet floor usually already define a direction and a slight
curve is therefore usually already driven. The curve effect is enhanced with high pile carpets.
Allow the user to drive a few meters straight ahead, stop and then accelerate again.
When driving straight ahead, pay attention that the user pushes the left and right
push rim uniformly.
Switching from a manual wheelchair to an active power assistance represents an initial
adjustment of the wheelchair driver.
Observe the following points to ensure the optimal use of the product properties:
- The push rim needs to operated relatively shortly and lightly - the drive takes care of the actual work
when required
- Do not "pull" on the push rim or guide it too long
- Operate the left and right push rim at the same time and uniformly when driving straight ahead
The following exercises will help in the initial phase when learning the new type of motion:
11
First exercise:
Driving straight ahead - push the
push rim at the same time with both
hands. Pushing and holding.
Once driving straight ahead and braking or decelerating has been mastered, driving through curves and
turning on the spot should be exercised.
Second exercise:
Driving through curves/turning
Third exercise:
Turning on the spot
STOP
When the push rim is manually delayed, the system also supports the braking process with the help of
the electric motor. This means for the occupant that less power is required even when braking the wheelchair.

+80%
5. Individual adjustment of the power assistance
Once the simple driving maneuvers are mastered safely, the power assistance can be increased from stage
1 to stage 2. The system now responds with much more assistance than in stage 1.
The programmed "follow-up" also increases with increasing power assistance. (follow-up is the time during which the motor continues to assist and drive after a drive movement). The more the motor follows
up after a drive movement, the less often must the wheelchair driver apply force via the push rim to
cover a given distance. The effect has a particularly great advantage when driving uphill. This promotes
a smooth motion sequence and saves the strength of the user.
Uniform pushing is particularly important in stage 2 to drive straight ahead in a precise manner. The
driver sometimes drives in a wiggly pattern especially when starting in stage 2. This has to do with the
follow-up of the wheel described above and also with the individual motion pattern of the driver. However, user tests have shown that novices securely master the function process after 1 - 2 days of getting
used to the new equipment.
Now allow the user to perform the driving exercises as described above also with power assistance in
stage 2.
6. Compensating for differences of force
To ensure uniform driving, the sensitivity [2], see page 4, must be adjusted between both e-motion
wheels so that possibly applied force differences of the driver are compensated. You can test this while
driving a straight course: If the driving patterns seems irregular and repeated pushing is required on one
side, more force is necessary on that side.
Increase or reduce the sensitivity of the one or other wheel to adjust the imbalance. The driver should
drive a short straight stretch after each adjustment process to be able to judge the effects of the adjustment.
If different settings of the sensitivity are chosen, the supplied labels "R" for the right wheel and "L"
for the left wheel must be affixed to the respective wheel to prevent them from being mixed up when
removing and re-installing them. If the setting is the same, the e-motion wheels can be installed at
either side.
7. Important information on the range
The greatest possible range can be achieved when driving on smooth, level ground and uniform speed.
Frequent acceleration and deceleration as well as constant steering correction can reduce the range
significantly. Rugged roads, wind conditions, hilly terrain but especially maneuvering with large power
assistance in tight spaces causes additional energy consumption which minimizes the range.
The energy consumption and thus the range also depend largely on the driving style of the user. Some
wheelchair drivers move with many short drive movements, allowing the push rims to slide permanently
slide through the palms of their hands thereby slowing them down again. The resulting displacement
of the sensor against the direction of travel feeds braking currents to the motor. The driver pushes and
brakes all the time but does not necessarily notice this. However, this driving patterns shortens the range
significantly.
The sensitivity should be markedly reduced for these user groups.
The impact of the rolling friction is also essential (e.g. in case of insufficient tire pressure of the steering
wheels of the wheelchair). For example, if the rolling friction is 6 % instead of only 3 %, this reduces the
range by one half. The range is also reduced by one half if 3 % uphill travel is added to a rolling friction
of 3 %. At an incline of 12 %, for example, the range is finally only 1/5 of the range on horizontal terrain.
Naturally, actual travel normally covers a mix of uphill driving, downhill slopes and level terrain which
have a combined impact on the range.
