1. Parameters
To meet the requirements of a diverse range of disabilities and customer requirements, the Esprit offers a wide range of user parameters
that can be modified. Programming can be performed as described in chapter 2, directly using the control unit without an additional
device.
The following parameters are stored in the system, user mode, attendant control and Opti-Box. Changes to these parameters can be made
directly using the control unit (see chapter 2), please refer to the table in chapter 3 for the possible settings.
Only the authorised specialist dealer can make any of the settings, under no circumstances can the wheelchair user do
this themselves. Similarly, the programming key included with this delivery must not be given to the wheelchair user.
1.1 “System” menu
Brake applied
•A time delay until the electromagnetic parking brakes deploy once the last drive command (joystick deflection) has been issued.
•In the factory setting the brakes are applied after 30 seconds. Continuous braking is avoided which means there is no unwanted annoy-
ing “clicking” noise.
•Immediately: if you need to come to a safe stop immediately, for example when approaching slightly inclined kerbs/steps.
Automatic cut-off
•The time it takes until the Esprit automatically cuts off to protect the battery pack.
Menu function
•Option of completely deactivating the menu function, i.e. all the setting options for the end customer.
Specialist dealer access is preserved.
Joystick deflection
•Reduces the required deflection to reach the maximum speed from 100% to 80%, 60% and 40%.
Joystick axle change
Various settings to change the four directions of travel.
If the “axle change” parameter has been changed, the Esprit may only be operated using the bumper bar for the control
unit (item no. 1565836).
Set factory settings
•Resets all functions of the Esprit to the delivery condition upon leaving the factory.
•All customised settings are deleted and the language will need to be reselected.
1.2 “User mode” menu
The settings made in this menu affect the driving characteristics with which the wheelchair user controls the Esprit themselves.
Maximum speed forwards
Specifies the maximum achievable speed going forwards.
•We recommend reducing the speed for beginners or when the wheelchair is being used exclusively indoors.
•It is also sensible to reduce the speed for elderly users.
Maximum speed backwards
Specifies the maximum achievable speed going backwards.
•For safety reasons this is a maximum of 70% of the forwards speed.
•Reduction if travel needs to be very slow (e.g. for wheelchair users with poor coordination, elderly users or when travelling indoors).
!
!

83
Acceleration
The time it takes to reach the maximum speed.
•The user may also refer to this as “reaction” (prompt/slow).
•Reduce in the event of tremor or ataxia and for children’s wheelchairs (generally when the wheelchair and wheelchair user are light-
weight).
•Increase to better overcome minor obstacles at low speeds e.g. indoor thresholds.
Delay
The time it takes to brake from the maximum speed to the required drive speed or to come to a stop.
•Reduce if very smooth wheelchair handling is required at low speeds, for example, for users with low upper body tone/core stability.
•Increase at low speeds if precise driving (e.g. in a narrow living room) or quick reaction is required.
Turning speed
Determines the maximum speed at which you can drive in a circle or around a bend.
•Reduction results in more stable straight-line driving at high speeds, slow/forgiving at low speeds, for example with attendant control.
•Increasing at low speeds (indoors) supports driving around tight corners, at high speeds the wheelchair is sensitive/quick to react.
Turning acceleration
The time it takes to reach the maximum turning speed.
•It is also generally described as sensitivity/reaction.
•Increasing this parameter results in quicker reaction/acceleration.
•Reduce to adapt to tremor or ataxia or for attendant control.
1.3 “Attendant control” menu
The settings made in this menu affect the intuitive attendant control, which is available as an optional accessory and which is operated by
the wheelchair user‘s attendant. It has the same parameters that have been described in chapter 1.2 (indep.user mode menu). In addition
the menu includes the sensor deflection parameter.
Sensor deflection
•Reduces the required deflection to reach the maximum turning speed from 100% to 80%, 60% and 40%.

2. Programming
The different menus are navigated in the same way as described in the Esprit opera-
ting manual. You also need the programming key (red) illustrated in the accompanying
diagram, which is included with every new Esprit delivery.
Parameters are selected and modified using the control unit joystick. Deflecting the
joystick up or down enables you to navigate through the menus, deflecting the joystick
sideways to the left or right makes settings to the different parameters, described in
detail in the following.
Buttons [22] to [24] enable you to select, save or test the modifications you have made
or leave a menu level.
The programming key must not be handed over to the user for safety
reasons. The driving parameters may only be modified by qualified
personnel (therapists, specialist dealers).
Adapting the various parameters should always be performed in the
presence of the wheelchair user because they can then test the modi-
fications immediately.
Should this not be possible, after reprogramming the user should take
a test drive under the supervision of specialist personnel to ensure
that the user can cope with the new driving characteristics.

(1) Note on the Driving Assistant parameter
The driving assistant supports the user while driving. If the gyro sensor in the control unit detects a slope, the software of the Esprit auto-
matically reduces the acceleration of the system to prevent tipping onto the anti-tippers. Only deactivate the driving assistant if the drive
system has been installed on a wheelchair that has a sufficiently long wheelbase and a fixed backrest that cannot be adjusted or folded
down. Only then is the tipping stability of the system still ensured. For this reason, anti-tippers must always be used in pairs. The system
must not be operated without anti-tippers.
If the driving assistant is deactivated, the gyro symbol at the top left of the status bar on the control unit disappears.
(2) Note on the Driving Assistant Calibration parameter
The driving assistant must be calibrated if a new swivel arm or a new bracket for the control unit is attached to the Esprit. For this pur-
pose, the Esprit must be placed on a flat, horizontally level surface.
The calibration is performed immediately when you confirm “Calibrate now”.

IMPORTANT
When the Esprit is initially delivered, the parameters visible in the table (bold and underlined) are predefined as the factory settings for
the drive modes ECO*, TOUR**, SPORT*** and SPEED****. However, when the Programming-Indep.user mode menu is called up, only the
factory settings for TOUR drive mode are displayed on the control unit’s display screen. The parameters for the SPEED mode are only for
info, it according to safety reasons not possible to set a CUSTOM drive mode with a max. speed of 8 km/h.
If one of the parameters is changed, it affects all the drive modes - ECO, TOUR, SPORT and Speed are then no longer available for selection.
Instead, the control unit’s display screen indicates CUSTOM mode, which comprises all the selected parameters in the
Programming-Indep.user mode menu.
ECO, TOUR, SPORT and Speed can be restored to the settings specified in the table at any time using Programming-System-Set factory set-
tings.
