4 Operating
Power Up
1. Turn on the DX System by pressing the On button of the DX Master Remote that is being used, e.g. Dolphin, Europa or Master Switch Interface. The Driving Scanner’s Module Status LED will come On to show that it is in Standby mode and ready to be used.
1. To use the Driving Scanner, press the Select Switch once.
This activates the scanner – all three Mode LED’s will light.
When all three lights first come on the Scanning Speed can be reset, (see section “Adjusting Scanning Speed”).
Select Mode
1. After 1 – 2 seconds the unit will start scanning through the 3 modes – Driving, Seating and Environmental. The LED for each mode will turn On in sequence.
2. When the LED is On for the mode you wish to use, press the Select Switch.
This selects the desired mode – Driving, Seating or Environmental. The Driving Scanner will cycle through each mode LED 5 times before returning to the Standby mode.
Driving
Once the Drive Mode has been selected, the Driving Scanner then begins to scan the driving directions.
A special scanning pattern has been developed to enable faster selection of the driving direction. This has been developed in conjunction with users of the DX Driving Scanner.
Improved features are:
• Special Scanning Pattern
• Automatic return to Forward direction LED after any wheelchair movement
➨ Pressing and holding down the switch in one of these positions will drive the wheelchair in that direction.
The Driving Mode will exit when the Scanner completes three circuits without the Select Switch being pressed.
Seating
When the Seating Mode has been selected, the Driving Scanner then begins to scan clockwise around the seating commands.
The Up and then the Down commands are available for each of the Seat Positioning Actuators, 1 to 4. If the first LED (forward), is selected, Actuator 1 will move Up. The
next LED (forward / right) would move Actuator 1 Down if the Select Switch was pressed.
➨ Pressing and holding down the switch in one of these positions will move the actuator in that direction.
The Seating Mode will exit when the Scanner completes three circuits without the Select Switch being pressed.
If the 5th Seat Actuator is also required the first two positions of the Environmental Mode operate can optionally be used, (see section
“Configuration”). The first position operates Actuator 5 Up and the second position moves it Down.
Note: For these functions to operate a DX Actuator Module, (e.g. CLAM, TAM), must be installed in the DX System. The Master Remote must also be
programmed correctly, (see section Programming).
Environmental
If the third Mode LED is selected the unit begins scanning in the Environmental Mode. The scanning is clockwise starting from the top LED.
There are two types of operation in the Environmental Mode – momentary and latching. The standard Driving Scanner is supplied with the first 4 LED’s being momentary selections and last 4 LED’s are latching selections.
Different configurations can be supplied if required.
When the Select Switch is pressed the attached Environmental Control or Communication Device is operated until the button is released.
➨ Pressing the switch in one of these positions will operate the attached Environmental Control or Communication Device.
Momentary Operation
With the momentary selections the unit will continue scanning as soon as the Select Switch has been released.
The momentary operation is ideal for use with simple external devices that need to be turned On or Off and then the user will want to perform a different type of function.
Momentary
Latching
Latching Operation
For the latching selections the unit will not continue scanning until the Select Switch is pressed continuously for 5 seconds. The Driving Scanner will remain in the selected function for the user to send the next signal to attached
Communication Device or Environmental Control or until the Select Switch is pressed continuously for 5 seconds.
➨ To exit from a Latched function press and hold down the switch for 5 seconds.
This is ideal for use with more sophisticated Communication Devices or Environmental Controls that have their own built in scanning systems.
The Environmental Mode will exit when the Driving Scanner completes three circuits without the Select Switch being pressed.
Note: For these functions to operate an external device (e.g. a Communication Device or an Environmental Control), needs to be connected to the Driving Scanner’s Environmental Socket, (see section Installation & Testing - Environment Controls).
It is possible to configure the first two Environmental Mode LED’s to operate the 5th Seat Actuator. (see sections Seating and Configuration).
Adjusting Scanning Speed
The Scanning Speed is the amount of time any LED is On, until the Scanner moves to the next LED.
This Scanning Speed can be adjusted every time the Driving Scanner is turned on. After the Select Switch is first pressed to turn the Scanner on – all three Mode LED’s will light.
When all three lights first come on the Scanning Speed is reset if the Select Switch is pressed and held down. The Scanning Speed then becomes the same as the length of time that the switch is pressed for.
➨ Press and hold down the Select Switch when all three Mode LED’s are On, to adjust the Scanning Speed.
If the Scanning Speed is adjusted, the Driving Scanner will use this new delay until the wheelchair is next turned off.
5 Installation & Testing
The Driving Scanner is a DX Module that can be connected to any wheelchair that has a DX control system.
Mounting
Mounting is carried out using 3 x M4 tapped holes on the base of the Scanner unit. A bracket needs to be produced to suit individual needs in order to accommodate this.
If a Flexible Arm Bracket is required, it is available on request from Dynamic.
If there is already a DX Master Remote on the wheelchair that the Driving Scanner is being fitted to – this can be mounted on the back of the wheelchair for the carer to operate.

35.5 mm 50 mm
7mm 7
35.5 mm Holes for M4 screws (This bracket will fit many of the Dynamic Specialty Controls.)
Connections
1. Turn the DX System Off and disconnect the DX Power Module from the batteries.
2. Using a DX BUS cable of a suitable length, the Driving Scanner can be connected into a spare DX BUS socket on another DX Module, (e.g. Power Module or Master Remote).
3. Plug the Select Switch into the Select Switch Socket on the lower end of the Driving Scanner. This switch can be the Buddy Button supplied with the Driving Scanner or an alternative momentary switch. The screw thread on the switch’s plug should be gently tightened to stop the plug falling out.
4. Reconnect the batteries to the DX Power Module.
5. Turn the DX system On.
6. If the DX Master Remote has not been programmed for use with the Driving Scanner, refer to the section Programming.
WARNING: Do not use the frame of a wheelchair or scooter as the earth return for any lights or actuators. Making any low resistance connection to the frame is regarded as a possible safety hazard and not allowed by international performance and safety standards for wheelchair and scooters.
Seating Controls
For electrically adjustable seating controls to be operated a DX Seat Actuator Module needs to be fitted to the DX System. This could be a DX–CLAM, (Combined Lighting and Actuator Module) or a DX–TAM, (Two Actuator Module).
If the fifth seat actuator needs to be used then the DX Driving Scanner needs to be configured for this. Before the Scanner is connected to the DX System it should be opened and 2 Header Jumper’s moved. This should be done by a competent technician or by Dynamic.
Jumpers on 1 & 2 (left positions) ➨ Actuator 5, Up & Down Jumpers on 3 & 4 (right positions) ➨ Environment Controls 1 & 2

6 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 Wizard 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
Two programming tools are available, the Wizard and the HHP.
HHP
The DX Hand Held Programmer (HHP) is the programming tool normally used by dealers, allowing easy adjustment of all commonly adjusted Drive Program parameters.
The DX HHP Manual should be read and understood before attempting to use it.
DYNAMIC WIZARD
The Wizard is a PC computer based tool, designed to program, configure and diagnose Dynamic Wheelchair Control Systems.
Note: As all program settings are stored in the Master Remote, replacement of the Master Remote in the DX System may result in a change in Drive Program values that may be substantially and dangerously different from those of the Master Remote it replaced. The Wizard may be used to up load and save the 'old' system settings for later reprogramming of the replacement unit.
Driving
The following parameters, need to be set in the “UCM Remote” using the Wizard programmer. Most remotes will already have these settings as standard.
Driving Parameters Comments
RJM Enable Yes
Reverse RJM Joystick Normal Reverse – swaps the forward and reverse driving directions.
Sleep Mode Enable Disable Enable – will put the DX System into Standby Mode in addition to the Driving Scanner’s Standby Mode.
Following are the settings for a DX system using a Driving Scanner on an average Indoor / Outdoor size rear wheel drive wheelchair. Settings will vary dependant on the driving performance of the wheelchair.
The following settings are suggested as a starting point.

The Driving Scanner will continue scanning as soon as the Select Switch has been released.
Adjusting Scanning Speed
When the Driving Scanner is activated by pressing Select Switch, the Scanning Speed is set to the length of time that the switch is pressed for. Pressing the switch for a longer time results in a slower scanning speed.
The Scanning Speed is set every time the Driving Scanner is turned on.
Appendix D: Product Disclaimer
Dynamic Controls 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.
The performance of controllers fitted to wheelchairs and scooters is very dependent on the design of the wheelchair or scooter. Final compliance must be obtained by the vehicle manufacturer for their particular vehicle. No component certificate issued by Dynamic Controls relieves a wheelchair or scooter
manufacturer from compliance testing their particular vehicle.
If Dynamic Controls 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.
Intended Use
The DX-ACC5 scanner control is an accessory of the DX system intended to enable the user to control driving, actuator and switch outputs, as present, by means of a single switch.

Appendix E: Electromagnetic Compatibility (EMC)
Dynamic Electronic Controllers have been tested on typical vehicles to confirm compliance with the appropriate EMC standards:
National and international directives require confirmation of compliance on particular vehicles. Since EMC is dependent 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, 2kV 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 return 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 and modules are electrically connected.
Ensure speed setting potentiometers are electrically connected to the vehicle frame.
Do not leave connections unnecessarily exposed.
Appendix F: Maintenance
1. All vehicle components should be regularly checked for loose, damaged or corroded connectors, terminals, or cabling. All cables should be restrained to protect them from damage. Damaged components should be replaced.
2. All switchable functions at the Dynamic Electronics System should be regularly tested to ensure they function correctly.
3. All Dynamic Electronic Components should be kept free of dust, dirt and liquids. If necessary wipe with a cloth dampened with warm water or alcohol.

Appendix G: Safety and Misuse Warnings
Warnings to be included in the User Manual
The following warnings are applicable to both the installer and the user, and must be passed on to the end user before use of the product.
• Do not install, maintain or operate this equipment without reading,
understanding and following the proper instructions and manuals, otherwise injury or damage may result.
• A warning must be conveyed to the operator that they have the responsibility to ensure that the vehicle is kept in a good safe operating condition, and ensure that components, such as cables, are protected from damage be securing them in optimum positions.
• Users and suppliers of Assistive Mobility products should give consideration to the possibility of a failure to operate, or an incorrect operation, by the product. Should an operator be left with limited or no mobility due to an equipment failure, they should still be able to summon assistance from where ever they may be.
• A warning must be conveyed to the operator that the controller could cause the chair to come to sudden stop. In situations where this may affect the safety of the operator, 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 operators capabilities. Incorrect settings could cause injury to the operator or bystanders, or damage to the vehicle or surrounding property.
• Incorrect or inappropriate programming can put the wheelchair into a dangerous state. Dynamic Controls accepts no responsibility of liability for accidents caused by incorrect programming. This Programming section and the Dynamic Wizard Installation Sheet / Online Help must be read and understood before attempting to program the controller.
• 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 setting other than default.
• When the controller is replaced it will be loaded with default parameters.
This may result in incorrect and dangerous programming for a particular wheelchair system if the wheelchair program installed in the Commando is not suitable for that wheelchair system.
• Do not attempt to drive or test the controller before the correct and suitable wheelchair program has been installed using the Wizard.
• The user must turn the system off while getting in and out of the wheelchair.
• Ensure the vehicle is turned off when not in use.
• Do not operate the vehicle if it behaves erratically, or shows abnormal response, heating, smoke or arcing. Turn the system off at once and consult your Service Agent.
• Do not operate the vehicle if the battery is nearly flat as a dangerous situation may result due to loss of power in an inopportune place.
• The controller should not be operated when the temperature is below -25°C or above 50°C.
• The wheelchair must not be driven when the manual park brake release is operated.
• The manual park brake release should not be operated on a slope.
• If the wheelchair drives without demand, press the On/Off switch.
• No connector pins should be touched as contamination or damage due to electrostatic discharge may result.
• 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 Dynamic Controls 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, turn the vehicle off immediately. Leave off while
transmission is in progress. Turn your wheelchair of scooter off before using your cell phone or portable communication devices.
• In the event of a fault indicator flashing while driving (battery gauge and/or Status LED), the operator must insure that the system is behaving normally. If not, the system must be turned off and a service agent contacted.
• Report any malfunctions immediately to your Service Agent.
Service and Configuration Warnings
• The following warnings are applicable to the installation technician only.
• Ensure that the programmed wheelchair complies with all prevailing regulatory requirements for your country and application.
• The completed installation must be thoroughly checked and all
programmable options correctly adjusted for safe operation prior to use.
• After the vehicle has been configured, check to make sure the vehicle performs to the specifications entered in the programming procedure. If the vehicle does not perform to specifications, turn the vehicle off immediately and re-program. Repeat this procedure until the vehicle performs to specifications.
