5Operation
On/Off and Key Lock system
The On/Off button toggles the system power on or off provided the DX
Remote is not locked.
The Key Lock system uses a magnetic key to power the wheelchair down in
such a way to prevent subsequent unauthorised power up and driving. This
function is required for TÜV approval and operates as follows :
Arming/Disarming the locking system
To arm the locking system hold the magnetic key on or near the key symbol
on the DX Remote front panel. The system will beep and automatically power
itself down and no LEDs should be lit.
To turn the chair back on press the On/Off button. This will cause the system
to power up but the chair needs to be disarmed before it can be driven - this
waiting to be disarmed state is indicated by the flashing key symbol.
To disarm the lock put the magnetic key on or near the key symbol - this will
cause the key to stop flashing and the chair may now be driven normally. If the
wheelchair is not disarmed within one minute, the Dolphin will automatically
turn itself off.
Using the system without the lock
If locking the chair is not required simply power the chair down by pressing the
On/Off button - all indicators will go out.
To turn the system back on press the On/Off button - the system is now able
to be driven without the use of the magnetic key.
Joystick OONAPU
All DX Remotes feature Out Of Neutral At Power Up (OONAPU) detection.
If the system is powered up while the joystick is not in the neutral position, or
an inhibit condition such as a battery charger is removed, the System Status
LED flashes rapidly for either as long as the condition persists or for a
maximum of 5 seconds.
If the condition persists, after 5 seconds a DX Module Fault (Flash Code 1) is
signalled on the System Status LED, and the Remote Status LED flashes. This
is a latching fault and must be cleared by powering the system down and up
again (with the joystick in neutral).
5 Operation
7
Page 12
No. 60025, Issue 5. January 1999
An OONAPU fault is also generated if the joystick source is changed. This
occurs when the Attendant / User switch on the DX-ACU is toggled or the
Drive Program is changed causing a joystick swap, while the joystick is not in
the neutral position. In these situations the fault is non-latching and the system
does not need to be powered down to clear the fault.
Drive Program Selection and Display
The Dolphin can offer up to five different Driving Programs, depending on its
configuration. (See Programming section.)
Profile Selection
Profiles can be selected using the Drive Program Select switch. Pressing this
switch will increment the Drive Program number up to the maximum
configured value. A further switch press will return the Dolphin to Profile 1.
Drive Program Display
The current Drive Program number is displayed on the 7-segment Drive
Program Display. When the ACU has control of the wheelchair, this display
is blank.
Drive Inhibit Display
A '-' is displayed on the Drive Program Display whenever the DX System is in
Drive Inhibit state, e.g. during battery charging, operation of actuators, active
Stop Switch (CLAM or TAM).
Remote Status Display
The Remote Module Status is displayed beside the 7-segment Drive Program
display. This LED will flash if there is an internal DX Remote fault, or if an
OONAPU fault has occurred.
System Status LED
The System Status LED is displayed above the On/Off switch. This LED is lit
if the system is turned on. It also flashes in groups called Flash Codes, to
indicate system faults.

No. 60025, Issue 5. January 1999
Lighting Control
A set of four lighting control switches, with feedback LED's, are provided to
control the Lighting System. A lighting module must be installed and enabled.
Suitable modules include: DX Combined Lighting Actuator Module (CLAM);
a DX Lighting Module (LM); or a DX Servo Lighting Module (SLM).
The Light switch toggles on or off the Head/Tail/Sidelight output,
independently of any other switch (except the On / Off switch). The Light
switch LED is lit when the lights are activated.
The Left or Right Indicator switch flashes the appropriate indicator output.
These are turned off by either pressing the same Indicator switch again, or
pressing the other Indicator switch, or the Hazard switch. Each associated LED
is lit when its matching Indicator switch is active.
The Hazard switch flashes both indicator outputs concurrently. The Hazard
LED also flashes if the Hazard LED is enabled. (See Programming section.)
The Hazard Indication can only be cancelled by pressing the Hazard switch
again.
All lighting functions will only operate with the system power on. Refer to the
relevant Installation Manual (e.g. LM or CLAM) for further lighting details.
Actuator Control
The DX Remote supports the control of up to five actuators if a correctly
configured actuator control module is present (see Programming section). For
example, a Combined Lighting Actuator Module (CLAM) can drive five
actuators or a Two Actuator Module (TAM) can drive two actuators.
The Dolphin has a set of five Actuator Select switches. Pressing an Actuator
Select switch will inhibit driving and select the appropriate actuator output as
indicated by the adjacent LED. The actuator order assigned in the Wizard as
Actuator 1, 2, 3, 4 and 5 Enable, is arranged on the Dolphin keypad as follows:
5 Operation
9
Page 14
No. 60025, Issue 5. January 1999
The actuator may then be adjusted up or down with
the Joystick, by deflecting the Joystick beyond half
travel in the forward / reverse axis.
To resume driving, press the current Actuator Select
switch again to deselect. Alternatively another
actuator may be selected directly.
If the user attempts to change modes (e.g. from
driving to actuator mode) while the Joystick is
deflected, the current mode will be terminated and
the Joystick must be returned to neutral position
before the newly selected mode will operate.
The Joystick Actuator parameter must be set to ‘yes’ and the Actuator While
Drive parameter must be set to ‘no’ if actuators are to be controlled with the
Dolphin Joystick, (See Programming section). An Actuator Remote Control
(ARC) can be used to control the actuators. If an ARC is used to control the
actuators the Actuator Select switches on the Dolphin are disabled and the
Joystick Actuator parameter should be set to ‘no’.
The above information is for normal, intended operation of actuators by the
Dolphin. Other options for actuator operation are possible, dependant on
programming. See the TAM Installation Manual for full explanations.
Refer to the relevant DX Module Installation Manual for further actuator
details.
Battery Gauge Display
Battery charge level is continuously indicated by a set of ten LED's. These are
arranged in an arc from left to right as three red, four orange and three green.
The Battery Gauge provides true, useable battery capacity information, and
indicates other related battery conditions. Full battery capacity is indicated by
all ten LEDs on.

DX Dolphin Connection with the DX System
The Dolphin has two DXBUS connectors which
enables any DXBUS cable to be used to interconnect
it to the remainder of the DX system.
The Dolphin will normally be connected directly to
one of the two PM DXBUS connectors.
Two DXBUS
connectors
Note : If only one DXBUS connector is used on the Dolphin and the
remaining connector is accessible to the wheelchair user, a dummy connector
should be fitted to the unused connector. This will comply with ISO7176.

Page 18
No. 60025, Issue 5. January 1999
Testing
Ensure that all DX Modules used in your DX System have been installed as
specified in their Installation Manuals. The Dolphin needs to be correctly
programmed for the appropriate wheelchair prior to testing.
A DX Remote contains the complete wheelchair system set up, from which all
DX Modules download their relevant information when the DX System is first
turned on. Refer to the later Auto Download section.
Powering Up Method
Power up the Dolphin by pressing the On/Off switch.
Power Up Response
The power up response for the Dolphin is :
! The System Status LED will come on steady.
Note : The first time the Dolphin is turned on, the System Status LED will
flash a fault. This is because the Dolphin must download its information to the
DX Power Module . Turn the Dolphin off then on to clear this fault. Refer to
the later Auto Download section.
! At least one of the LEDs on the Battery gauge will be on.
! The Mode display will indicate a number from 1 - 5.
DX Dolphin Check Sequence
Perform the following Dolphin check sequence :
1. Press the On/Off switch again and check the Power LED turns off. Press
it again to turn it on.
2. Press the Drive Program select switch a number of times. Check that the
display changes as expected.
3. Check all Lighting Buttons operate correctly.
4. Check the Key Lock system operates correctly.
5. Perform the remainder of the tests as outlined in the Testing sections of the
Installation Manuals of all other DX Modules used on the wheelchair.

7Batteries and Charging
Battery Type
The DX System is designed to perform optimally with either Lead-Acid or Gel
Cell 24 V deep cycle batteries, rated at 20 - 120 Amp hours. The maximum
average discharge rate must not exceed half the rated capacity, in Amp hours.
High continuous discharge rates dramatically reduces the available battery
capacity. For example, at a discharge rate equal to the rated capacity, the
available capacity is 50 - 60 %. At a discharge rate of half the rated capacity,
the available capacity is 70 - 80 %..
A wheelchair that draws maximum average battery current of 20 A, requires
a battery of at least 40 Amp hours. A battery of only 20 Amp-hours, would
begin to suffer a drop in performance at about half of its available capacity.
The 40 Amp hour battery would have a full performance range of 4.5 times
greater than the 20 Amp hour battery; a 80 Amp hour battery would only
increase this range by 2.5 when compared to a 40 Amp hour battery.
Battery Charging
The battery charger socket is a 3 pin XLR type with pin configuration as
shown below. Ensure that the charger used is compatible with this pin out
before connection.

Page 20
No. 60025, Issue 5. January 1999
The wheelchair is automatically disabled from driving whenever the battery
charger is plugged in. The Drive Program will show ‘’ to indicate that the
wheelchair is inhibited.
Connection of the battery charger will automatically power the wheelchair, if
the wheelchair was powered down at the time of connection. This allows the
progress of battery charging to be monitored on the Dolphin battery gauge. The
wheelchair can, if required, be subsequently powered down by pressing the
On/Off switch, and charging will still proceed normally.
Battery Gauge
The Battery Gauge provides true, useable battery capacity information. A full
battery with at least 85 % of rated capacity, is represented by all ten LED’s lit.
Some new batteries can start with as little as 80 % capacity, developing higher
capacity in their early life (sometimes up to 110 %), before slowly
deteriorating over their rated life.
As the battery voltage drops, the number of LEDs lit reduces from right to left.
When only the red LEDs are lit, the available battery capacity is typically less
than 10 %. At this level and below, the Battery Gauge flashes at 1 Hz to alert
the user that the wheelchair is running on reserve capacity. The battery
capacity will reduce more rapidly in the reserve capacity range.
Battery Saver
The Battery Saver is a feature programmed into the DX Remote. When the
battery capacity is in the reserve range (below 21V), the wheelchair
performance is reduced. This is to preserve the life of the battery by
encouraging the user to recharge the battery before it becomes harmfully flat.
Operating the wheelchair with more than two LEDs of the Battery Gauge lit
will generally give normal wheelchair performance. This is provided that the
battery size and the PM program settings are matched to the wheelchair.

Batteries and Charging 7
Page 21
No. 60025, Issue 5. January 1999
Battery Condition Warnings
A battery warning is shown by the Battery Gauge flashing its LEDs, the
number of which depends on what it currently has lit.
Battery High warning condition
This condition occurs when the battery voltage exceeds 28V, as measured by
the PM.
The cause can be :
!The wheelchair is still on charge and the batteries are full or faulty.
!The batteries are overcharged.
!The wheelchair is travelling down a slope and the batteries are full or
faulty.
The wheelchair will drive during this fault condition which will reset
automatically when the battery voltage drops below 28V.
Battery Low warning condition
This condition occurs when the battery voltage drops below 23.3V, when the
joystick is in neutral.
The cause can be :
If the Battery Gauge flashes with orange or green
LEDs lit, but the cause is not due to a Battery High
warning condition, the battery or battery wiring may
be faulty.
If the Battery Gauge flashes with just the left 3 or 4
LEDs after stopping the wheelchair, the battery may
be too small for the wheelchair type, or the battery
may be old or damaged.
The wheelchair will drive during this fault condition, but the flashing will
continue until the joystick is returned to neutral again.
A Battery Low warning normally coincides with a Low Capacity warning.

17
Page 22
No. 60025, Issue 5. January 1999
Low Capacity warning condition
When the calculated available battery capacity drops below 10% of full
capacity the two left most red LEDs flash.
The wheelchair will drive during this fault condition but it shows that the
battery is in the reserve capacity range and battery capacity will begin to
reduce rapidly. The Low Capacity warning will not stop until the batteries have
been recharged adequately.

8Programming
Warning !!
Incorrect or inappropriate programming of a DX System can put the wheelchair into
a dangerous state. Dynamic Controls accept no responsibility or liability for
accidents caused by incorrect programming. This Programming section, the HHP
Manual, and the Dynamic Wizard Installation Sheet/Online Help must be read and
understood before attempting to program a DX System.
Ensure that the programmed wheelchair complies with all prevailing regulatory
requirements for your country and application.
Introduction
The driving performance of the DX System is dependant on its programming.
Different features can be selected and parameters fine tuned for a particular
application, or to suit the requirements of an individual.
The DX Remote and the DX Power Module are the modules most responsible
for defining the driving performance of the DX System. Software in the DX
Remote, processes the joystick movements according to its Drive Programs,
and sends direction and speed commands to the PM.
Default Programs
The Dolphin is programmed during manufacturing with a set of factory default
settings which are incorporated into a controlled document by Dynamic. The
default settings programmed into a Dolphin will not be suitable for all DX
Systems and must be checked and reprogrammed prior to connecting with a
DX System.
The optimum settings for all programmable DX Modules are determined by the
wheelchair manufacturer (OEM). If more than one type of wheelchair is to be
used by the customer, each wheelchair type may have its own set of optimum
settings.
Warning : If a wheelchair is programmed with settings other than default,
under some very rare fault conditions default settings could be automatically
restored, thereby changing driving characteristics. This in turn could lead to a
chair moving in a direction or speed that is not intended. Programmers should
consider this risk when programming settings other than default.
8 Programming
19
Page 24
No. 60025, Issue 5. January 1999
Auto Download
The DX System has a feature called Auto Download. It is designed to
minimise the programming requirements associated with Module servicing by
down loading the correct programming to a replacement DX Module.
A DX Module with a flashing System Status LED is considered faulty and,
when serviced, is replaced by a new one. The replacement module is likely to
be programmed differently to the one that it replaces, which could leave the
wheelchair in a dangerous state. The DX System automatically detects that a
DX Module swap has occurred, and the programmed data from the old module
is transferred to the replacement module.
Auto Download is achieved by the DX Remote containing both its own
programming and also a backup copy of the programmed data for all other DX
Modules. When a module swap is detected, or a checksum error found in a
module, the DX Remote automatically down loads its backup copy to the
module. The Auto Down load occurs immediately on power up after the
Module has been replaced. This applies to all DX Modules except a DX
Remote.
Warning : When a Dolphin is replaced it will perform an Auto Down load
to all DX Modules. This may result in incorrect and dangerous programming
for a particular wheelchair system if the wheelchair program installed in the
Dolphin is not suitable for that wheelchair system.
Do not attempt to drive or test the DX System before the correct and suitable
wheelchair program has been installed in the Dolphin using the Wizard.
The Dolphin can be programmed with the Wizard using a ‘dummy’ DX
System and / or a 24V power supply, or on the wheelchair provided driving is
prevented e.g. by disengaging the drive wheels.
After replacing any DX Module, turn the DX System off, then on again, to
initiate the Auto Down load of the DX Remote backup data. When a Auto
Down load has occurred, but the system needs to be cycled on and off, a
Module Fault (Flash Code 1) is displayed on the DX Remote’s System Status
LED and also the Status LED of the offending module. When the System if
turned off then on again, the fault is cleared and the Auto Down load is
correctly terminated.

Programming Tools
Two programming tools are available, the Dynamic Wizard and the HHP.
Dynamic Wizard
The Wizard is a PC based tool suited to programming production runs of
identical wheelchairs or modules, or individual highly customised wheelchairs.
The Wizard is available in several versions :
OEMGenerally used by the wheelchair manufacturer. Able to
program a wide range of parameters.
DEALERSimilar in function to above, but with a reduced range of
programmable options. This ensures that options that the
manufacturer wishes to keep control of cannot be
disturbed. Parameters that may cause hazards or require
special expertise to be set are not available to adjust.
ENHANCEDAs above but with the ability to edit parameters that relate
DEALERdirectly to wheelchair accessories (e.g. actuators).
FACTORYCan only replace Standard or Custom Wheelchair
Programs. No editing or diagnostics available.
Warning : The Wizard is a very powerful tool and as such requires well
trained operators and a disciplined approach to usage and distribution.
It is up to the wheelchair manufacturer to determine whether they will allow
distribution of the Wizard to dealers. Refer to the Wizard Documentation for
further details.
DXBUS +DXBUS -
A Dolphin can be programmed with the
Wizard using a 24V power supply and an
optional PM. If the Dolphin is connected
directly to the 24V power supply, then a
DXBUS Cable can have one end modified to
connect to the power supply.

DX Dolphin Wizard Programming
The Wizard accesses a set of parameters that are programmed to define the
configuration desired by a wheelchair manufacturer.
Some parameters can be both read and written to (edited) by an OEM and a
Dealer. Other parameters can only be read but not edited. Some parameters
available to an OEM are not displayed by a dealer.
The DX System, with the Dolphin, supports up to five user selectable Drive
Programs. The Drive Programs govern the performance of the wheelchair, as
suitable for different environmental and user conditions. Drive Programs are
also adjustable with the HHP.
Remaining parameters are related to other system functions and DX Modules
which may, or may not, be included in your DX System. Parameters that may
be accessed by the HHP are marked with an asterisk (*).
Drive Program Parameters
The five Drive Programs (or Profiles) can be set up as, for example, an Indoors
program, an Outdoors program or a Sports program. These settings are
originally factory set to the values defined in the Chair Program used by the
Wizard during the down-loading process.
The values of the Drive Programs can be altered for a particular wheelchair
user using an HHP if necessary (except Damping Point and Sleep Timeout).
Note: As all program settings are stored in the Dolphin, replacement of the
Dolphin in the DX System may result in a change in Drive Program values that
may be substantially and dangerously different from those of the Dolphin it
replaced. The Wizard may be used to up-load and save the 'old' system settings
for later reprogramming of the replacement Dolphin.
Program (Profile) 6 is a special program that is automatically selected when an
Attendant Control Unit (ACU) is connected and in the Attendant mode. Note
that Program 6 is not programmable using the HHP on standard Dolphins.
When the ACU is disconnected, or it returns to the 'User Mode', the wheelchair
automatically reverts to the Program that was selected prior the ACU
becoming active (see ACU User Manual for more details).

The Wizard can be used to restrict the minimum and maximum limits for Drive
Program parameters adjustable with an HHP.
Sets the maximum output (linear) acceleration rate for large joystick
forward deflections, where 70% provides the quickest response.
Warning : Setting the Acceleration / Deceleration too low or too high can
result in an unsafe wheelchair. Test thoroughly after programming to ensure
that the wheelchair complies with regulatory requirements such as ISO7176
7176 and the GMD-TND Homologation Directive R04 for maximum allowable
braking distance.
The damping point defines the speed error size (of output speed verses
joystick demand speed) using progressive error reduction (ie acceleration
/ deceleration). Speed errors exceeding this value will be limited to the
programme maximum linear acceleration or deceleration rate. In other
words it sets the 'compromise' ratio between joystick directness /
responsiveness and chair controllability. Note: for most applications the
default value of 40% should not require adjusting. Achieving the desired
response is done by setting the appropriate acceleration / deceleration
values.
Warning : An unsuitably high or low value can make the wheelchair
unstable.

9Diagnostics and Fault Finding
DX Dolphin diagnostics can be examined from two platforms : from the Flash
Codes signalled with the System Status LED on the Dolphin (and on the HHP);
and from the Wizard which can provide more detailed information about the
fault.
Flash Code
Any fault condition on the DX system will cause the Dolphin’s System Status
LED to flash. Flashing occurs in bursts of flashes separated by a two second
pause. The number of flashes in each burst is referred to as the Flash Code and
indicates the nature of the fault. The title of the Flash Code fault is also
displayed by the HHP if connected to the faulty wheelchair.
Faults that affect the safety of the chair will cause the chair to stop while less
critical ones will be indicated but allow the chair to continue driving. Some
faults will automatically clear when the fault condition is removed, in which
case the System Status LED will become steady and the wheelchair may be
driven normally. Other faults are latched and must be cleared by turning the
DX System off, waiting for two seconds, turning it back on again.

10Product Disclaimer
Dynamic Controls Ltd. products built today allow our customer’s vehicles to
conform to national and international requirements.
In particular to: ISO7176-9Climatic Tests for Electric Wheelchairs.
ISO7176-14Power and Control Systems for Electric
Wheelchairs.
ISO7176-21Requirements and test Methods for
Electromagnetic Compatibility of Electric
Powered Wheelchairs and Scooters.
However the performance of controllers fitted to wheelchairs and scooters is
very dependant on the design of the scooter or wheelchair so final compliance
must be obtained by the vehicle manufacturer for their particular vehicle. No
component compliance certificate issued by Dynamic Controls Ltd. relieves a
wheelchair / scooter manufacturer from compliance testing their particular
vehicles.
If Dynamic Controls Ltd. controllers are fitted to vehicles or applications other
than wheelchairs and scooters, testing to appropriate standards for the
particular application must be completed as ISO7176 may be inappropriate.

11Electromagnetic Compatibility (EMC)
Dynamic Electronic Controllers have been tested on typical vehicles to confirm
compliance with the following appropriate EMC standards:
Emissions:CISPR22, class B
Susceptibility:IEC1000-4-3
ESD:IEC1000-4-2
Compliance levels and set-up as per ISO 7176, part 21.
National and international directives require confirmation of compliance on
particular vehicles. Since EMC is dependant on a particular installation, each
variation must be tested. The guidelines in this section are written to assist with
meeting EMC requirements.
Minimising Emissions
Motors :Motor brushes generate electromagnetic emissions. It may be
necessary to fit capacitors between the brush holders and motor
case. Ensure the leads are kept as short as possible.
A suitable capacitor is 4n7, 250V Ceramic.
Wiring :Keep wire lengths as short as practical for a tidy layout.
Minimise any wire loops, particularly loops of single wires as
opposed to wire pairs.
Endeavour to run wires in pairs or bunches.
Where practical, tie cables to wheelchair frame.
Immunity to Radiated Fields
Follow the wiring recommendations for minimising emissions.
Immunity to ESD
Follow the wiring recommendations for minimising emissions.
Ensure all vehicle sub-frames are electrically connected.
Ensure speed setting potentiometers are electrically connected to
the vehicle frame.
Do not leave connections unnecessarily exposed.

13Safety and Misuse Warnings
Do not install, maintain or operate this equipment without reading,
understanding and following the proper instructions and manuals, otherwise
injury or damage may result.
The completed installation must be thoroughly checked, and all programmable
options must be correctly adjusted for safe operation prior to use.
A warning must be conveyed to the wheelchair operator that the controller
could cause the chair to come to a sudden stop. In situations where this may
affect the safety of the user, this will require the fitting and wearing of a seat
belt.
Performance adjustments should only be made by professionals of the health
care field or persons fully conversant with this process and the driver’s
capabilities. Incorrect settings could cause injury to the driver, bystanders,
damage to the chair and surrounding property.
After the wheelchair has been set up, check to make sure that the wheelchair
performs to the specifications entered in the programming procedure. If the
wheelchair does not perform to specifications, turn the wheelchair off
immediately and re-program. Repeat procedure until the wheelchair performs
to specifications.
Do not operate the DX System if it behaves erratically, or shows abnormal
response, heating, smoke or arcing. Turn the system off, disconnect the battery
or open the battery overload switch, and consult your Service Agent.
Do not operate your DX System if the battery is nearly flat as a dangerous
situation may result due to loss of power in an inopportune place.
Ensure the controller is turned off when not in use.
No connector pins should be touched, as contamination or damage due to
electrostatic discharge may result. Dummy sockets in unused DXBUS
connectors should be left in place unless a new module is added to the system.
13 Safety and Misuse Warnings
55
Page 60
No. 60025, Issue 5. January 1999
Most electronic equipment is influenced by Radio Frequency Interference
(RFI). Caution should be exercised with regard to the use of portable
communications equipment in the area around such equipment. While the
manufacturer has made every effort to ensure that RFI does not cause
problems, very strong signals could still cause a problem. If RFI causes erratic
behaviour, shut the wheelchair off immediately. Leave off while transmission
is in progress.
In the event of a fault indicator flashing while driving (battery gauge and / or
status LED), the user must ensure that the system is behaving normally. If not,
the system must be turned off and a Service Agent called immediately.
Report any malfunctions immediately to your Service Agent.

18Anhang C:Deutschsprachige Warnhinweise
Der folgende Text muß in jedem Benutzerhandbuch erscheinen,
welches dieses DX-Modul verwendet.
Installations-Hinweise für die DX-Handbedienung, Type 1.
Der folgende Text muß in jedem Bedienungshandbuch abgedruckt werden,
welches die DX Handbedienung verwendet.
Das DX Installations-Handbuch ist ausschließlich für Rollstuhlhersteller
geschrieben worden. Sofern der Rollstuhlhersteller ein Bedienungshandbuch
zur Verfügung stellt, wird empfohlen zumindest die folgenden Auszüge an
passender Stelle mit in das Handbuch einzufügen. Die folgenden Auszüge sind
nicht geordnet und können je nach Zusammenhang in ein Handbuch eingefügt
werden.
Einleitung
Der Batterielade-Zustand wird dauernd an dem Batterieanzeiger angezeigt.
Wenn die vorletzte Stufe erreicht wird fängt der Anzeiger an zu blinken und
zeigt dem Fahrer damit an, daß die Batterien unverzüglich geladen werden
sollten. Die Steuereinheit arbeitet von dann an in einem 'Sparzustand' um die
verbleibende Batteriekapazität optimal auszunutzen - der Rollstuhl reagiert
dann langsamer und die Geschwindigkeit wird beschränkt.
Falls die Batterien soweit entladen werden, daß die Steuereinheit den Rollstuhl
nicht mehr sicher manövrieren kann, dann hält der Rollstuhl an und die
'POWER' Leuchtdiode zeigt die Störung 'Batterie-Entladung'
(7 Blinkzeichen, siehe Paragraph 8).
Wartungshinweise für die DX-Steuereinheit
a)Alle Anschlüsse zum DX-Steuersystem sollten regelmäßig auf ihre
Vollständigkeit hin überprüft werden. Lose, beschädigte oder
