    The star and mixed topologies both require the use of one or more DX BUS Expanders (DX-SKT-X3). The DX-SKT-X3 may be purchased from Dynamic Controls or a Dealer. For lowest cost and simplicity the in-line topology is generally preferred, provided the DX BUS length and voltage drop requirements described below can be met.

  • Page 21: Power Supply From The Battery

    GBK60027 DX-SLM Installation Manual Issue 5 5.4.4 Power Supply from the Battery When the servomotor and lighting require more current than the 12 A DX BUS has available, the SLM must be powered directly from the battery, and both battery negative terminals on the SLM must be used.

  • Page 22: Slm Connection To Lights

    The DX System is designed to perform optimally with either Lead-Acid or Gel Cell deep cycle batteries. Consult Dynamic Controls for other battery types. It is recommended that two 12 V batteries with capacity greater than 20 A hours be used.
  • Page 23 Note: If a DX2-PMAxxL is used, the lighting can be split between the Power Module and the DX-SLM. For example, the DX-SLM can drive the front indicators and side lights while the DX2-PMAxxL drives the rear indicators and side lights.

  • Page 26: Operation

    GBK60027 DX-SLM Installation Manual Issue 5 6 Operation 6.1 SLM Activation The SLM is operated by a DX Remote. Each DX Remote has different facilities and not all support a full lighting system. The operation of the lighting is therefore very dependent on what remote it is used with.

  • Page 27: Programming

    Incorrect or inappropriate programming of a DX System may put the wheelchair into a dangerous state. Dynamic Controls accept no responsibility or liability for accidents caused by incorrect programming. This chapter must be read and understood before attempting to program a DX System containing an SLM.
