DBM20A 12V/12V-System with Link Start Kit

Extra functions with Link Start Kit IBS-DBMLSK

  1. Link Start:
    Vehicle can be started from Aux battery by pushing Link-button.
  2. Automatic Winch support:
    the DBM20A recognises Winch usage and switches to Relay Support Mode for optimal load sharing on both batteries.
  3. Manual Winch support:
    30 minutes or 2 hours manual Relay Link can be activated by pushing the Link-Button once (for 30 minutes) respectively twice (for 2 hours) within 5 seconds. A reset of this mode can be done by pushing the Link-button for 10 seconds.
  4. Solar Charge:
    with installed solar panel on Aux battery the Main battery will be charged as well when Aux voltage is higher than 13.5V.
  5. Fast Charge:
    When the car is started the alternator first charges both Main and Aux battery (Fast Charge) and then the DBM20A switches to DC/DC Charge to get a 100% full Charge as configured.
  6. RBM Function:
    Relay Booster Module Function for Link Start when a low Main battery is detected.

For a better understanding of how the system is programmed read first the Programming the system steps on page 6. Otherwise it can be that the system has to be reinstalled.

Read aswell the notes for the mounting and wiring extension on page 8 before to start the installation.

Please read Instructions carefully prior to installation.

Choice of light blue connection IGN:   

 

  • With alternators (smart alternators) that cut off charge temporarily, connect IGN wire to Car Ignition (Terminal 15). When the alternator turns off, the DBM20A keeps charging until the Main voltage drops below 11.9V or the alternator kicks in again.
  • With all other alternators do not connect the light blue (IGN), DBM20A stops charging when the Main voltage drops below 12.7V. The DC/DC Charging automatically starts when Main voltage is higher than 13.3V.
  1. If needed connect the light blue IGN wire on Car Ignition (Terminal 15), otherwise leave unconnected.
  2. Connect the relay with the green wire (terminal 86) and a GND wire (terminal 85).
  3. Connect the power wires (minimal 25mm2) between plus battery main and relay and plus battery aux and relay.
  4. Connect all black GND wires.
  5. Connect now the red wire ((+) battery main) (ATTENTION: system is starting up -> refer to page 6 Programming the system). (Continue installation only after System has switched to Stand-By mode).
  6. With a IBS-DBMLSK connect the Link Push-Button to the yellow wire and make the GND connection as shown above.
  7. connect the blue wire ((+) battery aux) at last. 

If relay wasn’t found due to missing aux connection while programming follow the steps in Relay not found – what now?.

Notice

For a safe installation it is necessary to install the fuses in the red wire path ((+) battery main: 30A) and in the blue wire path (+) battery aux: 30A)!
