5 O PERATION
Compatibility with Power Wheelchairs
The model DX Series power wheelchair controller will function on those wheelchairs equipped with the following specifications:
C Motor resistance from 0 to 0.5 ohms;
C Motor voltage from 20V to 30V;
C Batteries greater than 20Ah lead acid;
C Peak motor current 60A - 80A maximum per motor output (model dependant);
C 12V or 24V Park Brake;
(Note: 12V motors can be used if the controller is programmed to half speed).
On/Off and Key Lock system
The On/Off switch toggles the system power on or off.
Warning: Do not attempt to drive the RemG80 until there is a number visible on the Drive Program Display e.g.
The Key Lock system uses a magnetic key to power the wheelchair down in such a way to prevent subsequent unauthorised driving. This function is required for TÜV approval and operates as follows :
Arming/Disarming the locking system
To arm the locking system, swipe the magnetic key across 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 wheelchair back on, press the On/Off switch. This will cause the system to power up but the wheelchair needs to be disarmed before it can be driven - this waiting to be disarmed state is indicated by the flashing key symbol LED.
To disarm the lock, swipe the magnetic key across the key symbol - this will cause the LED to stop flashing and the wheelchair may now be driven normally. If the wheelchair
5 Operation GBK60022, Issue 3. January 1999
Using the system without the lock
If locking the wheelchair is not required, power down by pressing the On/Off switch.
All indicators will go out.
To turn the system back on, press the On/Off switch. 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 or an inhibit condition is removed while the joystick is not in the neutral position, the System Status LED flashes rapidly for either as long as the condition persists, or for a maximum of 5 seconds. Removing an inhibit condition occurs in situations such as changing to a driving from a non-driving Drive Program, or removing a battery charger. If the condition persists, after 5 seconds a DX Module Fault (Flash Code 1) is signalled on the System Status LED, and the 7-segment display flashes. This is a latching fault and must be cleared by powering the system down and up again (with the joystick in neutral).
An OONAPU condition can also be generated by changing the joystick source. If the Drive Program is changed causing a joystick swap while the joystick is not in the neutral position a latching fault, as described above, will occur. If the Attendant / User switch on the DX-ACU is toggled while the joystick is not in the neutral position, the fault is non-latching and the system does not need to be powered down to clear the fault.
GBK60022, Issue 3. January 1999 5 Operation
Drive Program Selection and Display
The RemG80 can offer up to five different Driving Programs, depending on its configuration (see Programming section).
Drive Program Selection
Drive Programs 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 RemG80 to Drive Program 1 or Drive Program 0, depending on the setting of the ‘Allow Non-driving Profile’ Wizard parameter. If set to ‘yes’, Drive Program 0 appears between Drive Profiles 5 and 1. This must be set to ‘no’ for the RemG802 as it does not have an actuator mode. See the later Actuator Control section for details about actuator operation choices.
Drive Program 0
Drive Program 0 has all parameters set the same as Drive Program 1, but prevents the wheelchair from driving. This is a safety feature required by some regulatory authorities to prevent a sudden change in speed when progressing from Drive Program 5 (normally the fastest), to Drive Program 1 (normally the slowest).
Drive Program 0 can be used for its ability to inhibit driving, particularly when used for Actuator Mode (when actuators are enabled). When Drive Program 0 is enabled, the 7- segment LED displays a letter instead of a number. See the later Actuator Control section for details about actuator operation choices.
Drive Program Display
The current Drive Program number or actuator selected is displayed on the 7-segment Drive Program Display. Refer to the Actuator Control section for actuator display details. When the DX-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, some operation of actuators, active Stop Switch (CLAM or TAM).
5 Operation GBK60022, Issue 3. January 1999
Remote Status Display
The Remote Module Status is displayed by the 7-segment Drive Program display.
The currently displayed code 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 within 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. For Flash Code details, refer to the later Diagnostics and Fault Finding section.
Battery Gauge Display
Battery charge level is continuously indicated by a set of six LED's.
These are arranged in an arc from left to right as two red, two orange and two green.
The Battery Gauge provides true, useable battery capacity information, and indicates other related battery conditions. Full battery capacity is indicated by all six LEDs on.
Actuator Control
The DX Remote supports the control of up to five actuators if a correctly configured actuator control module is present. For example, a Combined Lighting Actuator Module (DX-CLAM) can drive five actuators and a Two Actuator Module (DX-TAM) can drive two actuators.
GBK60022, Issue 3. January 1999 5 Operation
There are four ways that RemG80 actuator control can be configured, using the Wizard.
Using Joystick to Select and Control Actuators Available to: RemG80
RemG805
The RemG80 enters actuator mode by pressing the Drive Program and Actuator Selection switch until the 7-segment displays ‘0'. The ‘Allow Non-driving Profile’
Wizard parameter must be set to ‘yes’ as Drive Program 0 can only be accessed if this is so. The wheelchair will not drive in this mode.
Selecting the Actuators
While in Drive Program 0, moving the joystick in the left and right turning directions will step through and select each of the available actuators. The symbols on the 7-segment display are used to indicate the currently selected actuator (a mixture of upper and lower case is used to avoid confusion between B and 8, and D and 0). The order of the letters follows the sequential order of the actuators, e.g. Actuator 1 is displayed as an ‘A’ and Actuator 5 as an ‘E’, if enabled.
A is also displayed for G805 lighting.
Controlling the Actuators
The actuator may then be adjusted up or down with the joystick, by deflecting it beyond half travel in the forward / reverse axis. The ‘Joystick Actuator’ parameter must be set to ‘on’. Refer to the ‘Num Actuator Button’ and
‘Joystick Actuator’ parameters in the Programming section.
To resume driving, select a Drive Program other than 0, using the Drive Program Selection switch.
If the user attempts to change between Drive Program 0 and a non-inhibited Drive Program 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.
5 Operation GBK60022, Issue 3. January 1999
Using Switches to select, Joystick to Control Actuators Available to: RemG80
RemG802
The two Actuator switches on the RemG80 can be used to select one of two available actuators. This option is only suitable if just two actuators are connected and enabled.
The ‘Allow Non-driving Profile’ parameter is set to ‘no’ and so Drive Program 0 is not available .
Selecting the Actuators
The left Actuator switch selects Actuator 1, the right Actuator switch selects Actuator 2. When an actuator is selected, the LED attached to that particular switch is lit, and the wheelchair will stop if it is driving (the ‘Actuator While Driving’
parameter is set to ‘no’ when the joystick is used to control actuators). When an actuator is selected, the Drive Inhibit is displayed. An actuator does not need to be deselected before the other is selected.
Controlling the Actuators
The actuator may then be adjusted up or down with the joystick, by deflecting it beyond half travel in the forward / reverse axis. The ‘Joystick Actuator’ parameter must be set to ‘on’. Refer to the ‘Num Actuator Button’ and
‘Joystick Actuator’ parameters in the Programming section.
To resume driving, the actuator may be de-selected, or a different Drive Program selected.
Using Switches to Select and Control Two Actuators Available to: RemG80
RemG802
The two Actuator switches on the RemG80 can be used to select and control one of two actuators. This option is only suitable if just two actuators are connected and enabled.
The ‘Allow Non-driving Profile’ parameter is set to ‘no’ and so Drive Program 0 is not available.
GBK60022, Issue 3. January 1999 5 Operation
Selecting and controlling the Actuators
Pressing the left Actuator switch both selects and extends Actuator 1. Each switch press toggles the actuator between extend and retract. The right Actuator switch similarly selects, extends and retracts Actuator 2. The Drive Inhibit is displayed only while the Actuator switch is pressed. Once it is released, the wheelchair will resume driving.
The ‘Joystick Actuator’ parameter must be set to ‘no’ and ‘Num Actuator Button’ set to ‘one’. Refer to the ‘Num Actuator Button’ and ‘Joystick Actuator’ parameters in the Programming section.
Using Switches to Control One Actuator Available to: RemG80
RemG802
If only one actuator is connected and enabled in the DX System, the two Actuator switches on the RemG80 can be used to control it. The ‘Allow Non-driving Profile’
parameter is set to ‘no’ and so Drive Program 0 is not available. Actuator 2 must be disabled.
Selecting the Actuator
With only one actuator available, no selection function is required.
Controlling the Actuator
The actuator is extended by pressing the left Actuator switch and retracted by pressing the right Actuator switch. The ‘Joystick Actuator’ parameter must be set to ‘no’ and ‘Num Actuator Button’ set to ‘two’. Refer to the
‘Num Actuator Button’ and ‘Joystick Actuator’ parameters in the Programming section.
The above information is for normal, intended operation of actuators by the RemG80 and variants. Other options for actuator operation are possible, dependant on programming. See the DX-TAM Installation Manual for full explanations.
5 Operation GBK60022, Issue 3. January 1999
Lighting Control
The RemG805 supports the control of four lighting functions if a correctly configured lighting module is present. Suitable modules include: DX Combined Lighting Actuator Module (CLAM); a DX Lighting Module (LM); or a DX Servo Lighting Module (SLM).
There are two ways that the G805 can control lighting.
Using Switches to Control Lighting
The left and right actuator switches are used to control lighting functionality.
A single short press (less than 1 second) of the left or right actuator switch toggles the left and right indicators on and off. Each associated LED flashes when its matching Indicator switch is active.
A single long press (greater than a second) of the left actuator switch will toggle the side lights on and off. There is no LED feedback when the side lights are active.
A single long press (greater than 1 second) of the right actuator switch will toggle the hazard lights on and off. Both left and right LEDs will flash when the hazard lights are active.
Using Joystick to control Lighting
The joystick can also perform limited lighting functions. The G805 enters actuator mode by pressing the Drive Program and Actuator Selection switch until the 7-segment displays ‘0'. The ‘Allow Non-driving Profile’ Wizard parameter must be set to ‘yes’ as Drive Program 0 can only be accessed if this is so. The wheelchair will not drive in this mode.
Selecting Lighting
While in Drive Program 0, moving the joystick in the left and right turning directions will step through and select each of the available actuators. The symbols on the 7-segment display are used to indicate the currently selected actuator. Lighting is signified by the letter ‘L’.
GBK60022, Issue 3. January 1999 5 Operation
Side Lights
Hazard Lights Joystick Full Forward
Full Reverse
Controlling Lighting
Lighting may then be turned on and off with the joystick, by deflecting it beyond half travel in the forward / reverse axis. The ‘Joystick Actuator’ parameter must be set to ‘on’
and ‘Num Actuator Button’ set to ‘one’.
Forward deflection of the joystick will toggle the side lights on and off.
Reverse deflection of the joystick will toggle the hazard lights on and off. Both left and right actuator switch LEDs will flash when the hazard lights are active.
To resume driving, select a Drive Program other than 0, using the Drive Program Selection switch. If the user attempts to change between Drive Program 0 and a non- inhibited Drive Program 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.
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.
G80A and G80T Switches
The G80A has two 3.5mm phono sockets and the G80T has two momentary switches which can be used to duplicate the functions of the On/Off (labelled ) and Drive Program (labelled ) switches on the keypad. Any momentary switches can be plugged into the available sockets of the RemG80A.
Pressing a G80A switch or moving a G80T toggle switch in a downwards direction and allowing it to spring back to centre, will either toggle the system status on/off or step up a single Drive Program (depending on the switch used). Moving a G80T toggle switch in an upwards direction will have no effect.
The ‘Wrap Profiles’ parameter must be set to ‘Yes’.
Note : Insertion of the G80A On/Off external switch into the On/Off socket while powered down will cause the wheelchair to power up.
Warning : External switches must be clearly labelled as to their function. When looming for these switches, care must be taken to ensure they can not be transposed.
6 Installation and Testing GBK60022, Issue 3. January 1999
6 I NSTALLATION AND T ESTING
RemG80 Mounting
The RemG80 Remote can be mounted on either side of the wheelchair, in an upright position, using four Roll Tap Cap screws.
Warning: For safe installation, select a screw length that protrudes between 4mm and 10mm into the case.
Note : If the programmer socket needs to be accessible when the DX Remote is mounted, make allowance for this prior to fitting.
GBK60022, Issue 3. January 1999 6 Installation and Testing
RemG80 Connection with the DX System
The RemG80 has two DXBUS connectors which enables any DXBUS cable to be used to interconnect it to the remainder of the DX system.
The RemG80 will normally be connected directly to one of the two PM DXBUS connectors.
Note : If only one DXBUS connector is used on the RemG80 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.
DXBUS cables are available in the following lengths :
DXBUS CABLE, Straight, 0.3 M Part/Order Number GSM63003 DXBUS CABLE, Straight, 0.5 M Part/Order Number GSM63005 DXBUS CABLE, Straight, 1.0 M Part/Order Number GSM63010 DXBUS CABLE, Straight, 1.5 M Part/Order Number GSM63015 DXBUS CABLE, Straight, 2.0 M Part/Order Number GSM63020
DXBUS cables are also available fitted with a ferrite bead to improve Electromagnetic Compatibility (EMC).
DXBUS CABLE, Ferrite, 2.0 M Part/Order Number GSM63020F
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 GBK60022, Issue 3. January 1999
Testing
Ensure that all DX Modules used in your DX System have been installed as specified in their Installation Manuals. The RemG80 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.
Power Up Response
Power up the remote by pressing the On/Off switch.
The power up response for the RemG80 is :
! The System Status LED will come on steady.
Note : The first time the RemG80 is turned on, the System Status LED will flash a fault. This is because the RemG80 must download its information to the DX Power Module. Turn the RemG80 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.
RemG80 Check Sequence
Perform the following RemG80 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 (RemG805).
4. Check all other switches operate correctly.
5. Check the Key Lock system operates correctly.
6. 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.
GBK60022, Issue 3. January 1999 7 Batteries and Charging
7 B ATTERIES AND C HARGING
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 satisfactory performance of the DX system is critically dependent on the type and state of the batteries. The battery charger used must be correctly selected and adjusted according to the battery manufacturer’s instructions. Failure to do so may damage or destroy the batteries, give poor range, or be potentially dangerous. Batteries should not be abused (for example by deep discharging or overcharging) and must be operated and maintained according to the manufacturer's instructions.
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. The safety link between B- and the Inhibit pin must be fitted so that the wheelchair is prevented from driving when the batteries are being charged. The Drive Program will show ‘ ’ to indicate that the wheelchair is inhibited.
Warning : Do not disconnect batteries or open circuit the circuit breaker during charging. This is dangerous to both people and equipment.

Inhibit
Battery - Battery +
DX-RemG80 Battery Charger Plug
(front view)
Battery Charger
Note : The inhibit is shorted to B- external to the DX-RemG80.
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 RemG80 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 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 flash per second 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 drops below 21V to the reserve range (only two red LEDs lit), 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.
GBK60022, Issue 3. January 1999 7 Batteries and Charging
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.
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 warning 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 2 or 3 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.

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 P ROGRAMMING
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 DX-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 RemG80 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 RemG80 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.

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.
When a DX Module is replaced, it is likely that the replacement module is programmed differently from the one that it replaces. This could leave the wheelchair in a dangerous condition. 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 downloads 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 RemG80 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 RemG80 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 RemG80 using the Wizard.
The RemG80 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 :
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 Dealer As above but with the ability to edit parameters that relate 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 distribute the Wizard to dealers. Refer to Wizard Documentation for further details.
A RemG80 can be programmed with the Wizard using a 24V power supply and an optional PM. If the RemG80 is connected directly to the 24V power supply, then a DXBUS Cable can have one end modified to connect to the power supply.

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 RemG80 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 the RemG80 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.
5. Select ‘UCM Remote’ or the required group of parameters.
6. Scroll through the list of parameters and adjust as necessary.
7. Press «Enter» to accept the changes, or «Esc» to exit without saving. Select the File, Save menu option. These values will then be part of the Standard Chair Program for the “SuperChair, Deluxe”.
GBK60022, Issue 3. January 1999 8 Programming
Down-load the “SuperChair, Deluxe” to a RemG80 as follows.
1. Connect the Wizard serial communications cable to the RemG80 programmer socket and return to the main menu of the Wizard.
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 ‘Program Wheelchair’ option.
5. Choose if the Chair Program is to be down-loaded to the ‘Total System’ (to program a fully built up chair system) or just the ‘UCM Remote’ (to pre-program the RemG80 only).
6. Press «Enter» to write the Chair Program data.
7. Disconnect the RemG80 and repeat for as many RemG80's, or DX Systems, as required, by repeating steps 4 through 7.
DX RemG80 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 RemG80, 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.
