  • How Do I Activate Equalisation or Forced Absorption Modes on MultiPlus-II?

    I need some guidance on activating the Equalisation or Forced Absorption modes on my MultiPlus-II. Can someone walk me through the steps, especially using the front panel switch and the remote panel?

    To activate the Equalisation or Forced Absorption modes on your MultiPlus-II, it’s important to follow a specific sequence, particularly with the front panel switch and the remote panel.

    Ensure that all switches, including any remote and front panel switches, are set to the ‘on’ position.

    Important – None of the switches should be in the ‘charger only’ mode.

    The key step involves a rapid toggling action:

    You need to quickly switch from ‘on’ to ‘charger only’ and back to ‘on’. This action must be performed swiftly enough to avoid lingering in the ‘off’ position, as this could inadvertently power down the unit, necessitating a restart of the procedure.

    This rapid toggling action is critical in signaling the unit to enter either Equalisation or Forced Absorption modes. The process might require some familiarity, especially with the front switch on the Compact version of the unit.

    The remote panel tends to be more forgiving in this regard, offering a somewhat more intuitive experience for this specific operation.

    To activate these modes on your MultiPlus-II, first, check that all switches (front, remote, and panel) are set to ‘on’. Remember, these modes only work after the normal charging cycle has finished and the charger is in ‘Float’.

    The do the following:

    • Quickly switch from ‘on’ to ‘charger only’ and hold for 0.5 to 2 seconds.

    • Rapidly switch back to ‘on’ and hold for another 0.5 to 2 seconds.

    • Finally, switch again to ‘charger only’ and leave it in that position.

    Observe the ‘Bulk’, ‘Absorption’, and ‘Float’ LEDs on the unit and the MultiControl panel (if connected). They will flash five times, followed by each lighting up sequentially for 2 seconds.

    The mode your charger enters depends on when you switch back to ‘on’:

    • During the ‘Bulk’ LED’s illumination: Equalization mode.

    • During the ‘Absorption’ LED’s illumination: Forced Absorption mode.

    • After the LED sequence completes: Returns to ‘Float’.

    • If you leave the switch in ‘charger only’ mode, it remains there and returns to ‘Float’.
