  • Page 7: Introduction

    1 Introduction 1.1 The DX system DX is a modular, expandable power wheelchair control system. This modularity allows the system to be expanded and customized to particular end-user needs and handles the requirements from basic driving to full environmental control. A power module and a master remote are required along with a DX BUS cable to form the base of any DX system.

  • Page 8: The Dx-Gb Gearless Brushless Controller

    1.2 The DX-GB Gearless Brushless controller The Dynamic DX Gearless Brushless Power Module (DX-GB) is a DX BUS compatible module that converts signals generated by a DX Remote into high current outputs. These outputs drive the motors that control the powerchair speed and direction. The combination of a DX-GB and DX Master Remote give an exceptionally smooth, powerful, and safe drive system.

    2 Installation and Testing 2.1 DX-GB Mounting M5 x 10mm or #10/32 x 0.39" (max) TYP x 3 74 mm 2.91" The DX-GB must be mounted with the lid-down and at a minimum incline of 5° from horizontal. 5° min, 90° max The position and orientation must give maximum mechanical protection to the DX-GB.

  • Page 11: Connections And Wiring

    For peak performance, locate the DX-GB so that air can flow over and around the case. Make sure that the mounting position minimizes bending and flexing stresses on the motor cables, especially with moving motor/wheel suspension. Use all three mounting points to attach the DX-GB. The use of M5 or #10/32 screws that engage up to 10mm/0.39"...

  • Page 13 The final connection to the Battery Positive (+) terminal must not be made until the powerchair is completely wired and ready for testing as described in the Testing section. The DX-GB has been designed to perform optimally with either Lead- Acid or Gel Cell 24 V deep cycle batteries. Ensure that the battery capacity and the battery charger rating are sufficient to not restrict the high performance needs of the system.

  • Page 14: Motor And Park Brake Connections

    2.2.3 Motor and Park Brake Connections The DX-GB has two motor cables (left and right) that plug directly into the motors. Programming note: You can program the DX-GB to swap the motor connections, if necessary. 2.2.4 DX BUS Connections The DX-GB communicates with the rest of the DX system through the DX BUS. The DX BUS also supplies power to every other DX Module.

  • Page 15: Drive Control Input (Dci) And Obc Connections

    2.3 Drive Control Input (DCI) and OBC Connections The DX-GB provides support for an On-board Battery Charger (OBC), an ‘inhibit’, and a ‘speed limit’ function (either digital or analog) through the Drive Control Input (DCI) socket as shown to the right. The On-board Battery Charger supports up to 12 Amperes (RMS) directly through the connector.

  • Page 16: Dci - Analog Mode

    2.3.1 DCI – Analog Mode When the Digital Input setting is set to ‘No’, the DCI will limit the drive speed of the chair to a value proportional (linear) to the resistance of the DCI Loop, typically through use of an analog potentiometer. A loop resistance of 220 ohms will have no effect on the chair speed, while a value of 56 ohms will cause the chair to slow down to the value set in Reduced Speed.
  • Page 17 Example 2 A powerchair has a seat raise function and an On-board Battery Charger (OBC). The DX-GB will automatically limit the speed by an amount proportional to the seat height, and inhibit drive when the OBC is plugged in. When plugged in, an internal switch in the OBC will activate causing a closed circuit (<10 ohms).

    3. Make the final connection to the Battery Positive (+) terminal and close the circuit breakers. Note: If the used master remote is not pre-programmed with the intended chair program, download the program for this chair with the Dynamic Wizard. : Issue 1 – June 2007 GBK64048...
  • Page 19 4. Press the Power button to turn the DX system on. Ensure it turns on correctly. Note: The first time the DX Master Remote is turned on, the System Status LED will flash a fault. This is because the DX Master Remote must download its information to the DX-GB.

  • Page 20: Programming

    3 Programming Warning: Performance adjustments should only be made by professionals in the health care field or by persons fully conversant with the adjustment process and the user’s capabilities. Incorrect settings, or programming in an unsafe location, can cause injury to the operator or bystanders, or damage to the vehicle or surrounding property.

  • Page 21: Description Of Parameters

    Note: The Wizard needs the DX-GB database update to recognize the DX- GB. Make sure you have the latest version of the Wizard database installed. The latest version is available for download on the Dynamic website: www.dynamiccontrols.com. Warning: Always test the vehicle after programming to ensure that the intended operation is achieved.

  • Page 23 Setting Description Drive Profiles Sets the maximum turning speed for the selected profile when the selected joystick is pushed fully left or fully right. Set to a low value Turning Speed @ for a slower controlled wheelchair drive performance particularly Maximum when driving indoors.

  • Page 24: Dx-Gb Specific Parameters

    3.2.2 DX-GB Specific Parameters Setting Description Joystick How non-linear the speed response is to the joystick position, Joystick Speed with 0 giving a linear response. This has no effect on the Progression maximum speed. Used to allow fine low-speed control. How non-linear the turning response is to the joystick position, Joystick Direction with 0 giving a linear response.
  • Page 25 Setting Description Drive Performance Sets the accuracy of the control loop response at higher speeds. Higher values give more precise control but may feel True-Track (Torque) harsh and require more power from the battery. Dampens (or softens) the chair reaction to joystick commands. Tremor Range Higher values give smoother but less responsive drive performance.
  • Page 26 Setting Description Battery Changes the battery level gauge display to use a voltmeter Voltmeter Battery style display rather than the standard battery gauge which tries Gauge to determine the battery capacity. When using the voltmeter-style battery gauge, enabling this Slow Batt Time Scale parameter will lessen the responsiveness of the gauge, Driving damping down any voltage ‘wavering’.
