5 Operation

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

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.

Operation 5

Page 13

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

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.

Installation and Testing 6

Page 17

No. 60025, Issue 5. January 1999

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.

The DXBUS cables are available in the following standard lengths:

DXBUS Cable, Straight, 0.12 M Part/Order Number GSM 630012 DXBUS Cable, Straight, 0.3 M Part/Order Number GSM 63003 DXBUS Cable, Straight, 0.5 M Part/Order Number GSM 63005 DXBUS Cable, Straight, 1.0 M Part/Order Number GSM 63010 DXBUS Cable, Straight, 1.5 M Part/Order Number GSM 63015

The DXBUS is also available with a ferrite.

DXBUS Cable, Ferrite, 2.0 M Part/Order Number GSM 63020F

Other cable lengths in multiples of 0.1 m are available on request.

Warning: Any protruding screws should be either plastic or plastic coated to prevent short circuits occurring with the DXBUS Cable pins.

6 Installation and Testing

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.

7 Batteries 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.

7 Batteries and Charging

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.

7 Batteries and Charging

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.

8 Programming

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

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 8

Page 25

No. 60025, Issue 5. January 1999

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 :

OEM Generally used by the wheelchair manufacturer. Able to

program a wide range of parameters.

DEALER Similar 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.

ENHANCED As above but with the ability to edit parameters that relate DEALER directly to wheelchair accessories (e.g. actuators).

FACTORY Can 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.

Dolphin DXBUS Pins

8 Programming

Page 26

No. 60025, Issue 5. January 1999

HHP

The DX Hand Held Programmer (HHP) is the normal programming tool used by dealers, allowing easy adjustment of all commonly adjusted Drive Program parameters.

Warning : The DX HHP is for use only by wheelchair manufacturers, their authorised dealers and support personnel. It is not intended for use by the wheelchair user.

The DX HHP Manual should be read and understood before attempting to use it.

Wizard High Volume Programming.

Programming in the factory environment is normally done using the Wizard.

With the Wizard’s Create a new Chair Program option, you can set up the standard parameters for the Dolphin and any other modules used for a particular wheelchair. This Chair Program is then saved to disk under a name such as "SuperChair, Deluxe, with lights" and can be down-loaded to a Dolphin at the push of a button.

Example

Modify/Edit the "SuperChair, Deluxe, with Lights” Chair Program as follows.

1. Enter the Wizard’s Main Menu screen as described in the Wizard Installation Sheet.

2. Use the keyboard or the mouse, to select the File, Open menu option.

3. Select the “SuperChair, Deluxe” program from the dialog box.

4. Select the ‘Edit Module Parameters’ menu option.

6. Select ‘UCM Remote’ or the required group of parameters.

7. Scroll through the list of Dolphin parameters and adjust as necessary.

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.

Max Forward Speed * Range : 10 - 100% Default : 100 OEM Access: Read / Write Dealer Access: Read / Write

Sets the maximum speed obtainable for maximum forward joystick deflection.

Forward Acceleration * Range : 10 - 70% Default : 40 OEM Access: Read / Write Dealer Access: Read / Write

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.

Forward Deceleration * Range : 15 - 100% Default : 70 OEM Access: Read / Write Dealer Access: Read / Write

Sets the maximum braking effect (linear deceleration) for large joystick deflection back towards neutral, where 100% provides maximum braking effect.

No. 60025, Issue 5. January 1999

Damping Point * Range : 10 - 100% Default : 40 OEM Access: Read / Write Dealer Access: Read / Write

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.

Joystick Source * State : Local / Remote Default : Local OEM Access: Read / Write Dealer Access: Read / Write

Selects whether the Drive Program will use the Dolphin's built in joystick or an external RJM based input control device.

Reverse J/S - Fwd/Rev State : Normal / Reverse Default : Normal OEM Access: Read / Write Dealer Access: Read only

Reverses the direction of the Dolphin’s inbuilt joystick, This can be set for each profile.

If set to ‘Normal’, forward and reverse joystick deflection causes forward and reverse motion respectively.

9 Diagnostics 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.

DX System Status LED Flash Code

Likely Cause of Condition and Possible Action

DX Module Fault (see Limp Mode below) Cause: An Auto Download has occurred. Action < Turn the Dolphin off then on again. Cause: The Dolphin is not correctly programmed. Action < Try reprogramming the Dolphin. Cause: Connection between DX Modules may be faulty,

or there may be an internal fault in a Module.

Action < Check DXBUS connections and replace where

necessary.

< If the Status LED on another Module is

flashing, replace the Module.

< An expected module may not be present (e.g.

the DX Lighting Module).

Likely Cause of Condition and Possible Action

CANH Fault (see Limp Mode below) Cause: 1. An invalid voltage has been detected on the

DXBUS CANH line.

2. Communication is not possible using the CANH wire, or the CANH and CANL wires are shorted together.

3. Hazard lights were turned on when the DX System was turned on.

4. The CANH is used to generate a Kill signal by any DX Module which detects an unsafe condition, or by an external device such as an emergency stop switch. The CANH wire is pulled to either Battery + or Battery - and causes the DX System to shut down.

Action < Check the continuity of the DXBUS cable.

< Check for shorts between DXBUS pins. An

open or short circuit on another DX Module can cause this fault.

< If the Hazard Lights were already switched on

when the DX System was turned on, Flash Code 10 and Limp Mode (slow driving) may result. To clear this fault, turn the Hazard Lights off, then turn the DX System off then on again.

< If generated by a Kill signal, the cause of the

fault is severe.

Stall Timeout Fault

Cause: The motor current has been at, or close to, current

limit for longer than the Stall Timeout parameter value.

Action < Turn the DX System off then on again.

10 Product Disclaimer

Dynamic Controls Ltd. products built today allow our customer’s vehicles to conform to national and international requirements.

In particular to: ISO7176-9 Climatic Tests for Electric Wheelchairs.

ISO7176-14 Power and Control Systems for Electric

Wheelchairs.

ISO7176-21 Requirements 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.

Product Disclaimer 10

Page 57

No. 60025, Issue 5. January 1999

11 Electromagnetic 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.

13 Safety 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

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.

18 Anhang 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 korrodierte Buchsen und Stecker sowie beschädigte Kabel sollten ausgetauscht werden.
