Equalize with Multipuls 12/3000 and Digital Multicontrol.

I have a Multiplus 12/3000 with the Digital Multicontrol display. Can I get the Multiplus to equalize somehow?

Hi @groger, from the manual:

3.3.3 Activating equalisation or forced absorption

The MultiPlus can be put into both these states from the remote panel as well as with the front panel switch, provided that all switches (front, remote and panel) are set to “on” and no switches are set to “charger only”.

In order to put the MultiPlus in this state, the procedure below should be followed.

If the switch is not in the required position after following this procedure, it can be switched over quickly once. This will not change the charging state.

NOTE: Switching from “on” to “charger only” and back, as described below, must be done quickly. The switch must be toggled such that the intermediate position is 'skipped', as it were. If the switch remains in the “off” position even for a short time, the device may be turned off. In that case, the procedure must be restarted at step 1. A certain degree of familiarisation is required when using the front switch on the Compact in particular. When using the remote panel, this is less critical.

Procedure:

1. Check whether all switches (i.e. front switch, remote switch or remote panel switch if present) are in the “on” position.

2. Activating equalisation or forced absorption is only meaningful if the normal charging cycle is completed (charger is in 'Float').

3. To activate:
a. Switch rapidly from “on” to “charger only” and leave the switch in this position for ½ to 2 seconds.
b. Switch rapidly back from “charger only” to “on” and leave the switch in this position for ½ to 2 seconds.
c. Switch once more rapidly from “on” to “charger only” and leave the switch in this position.

4. On the MultiPlus (and, if connected, on the MultiControl panel) the three LEDs “Bulk”, “Absorption” and “Float” will now flash 5 times.

5. Subsequently, the LEDs “Bulk”, “Absorption” and “Float” will each light during 2 seconds.
a. If the switch is set to “on” while the “Bulk” LED lights, the charger will switch to equalisation.
b. If the switch is set to “on” while the “Absorption” LED lights, the charger will switch to forced absorption.
c. If the switch is set to “on” after the three LED sequence has finished, the charger will switch to “Float”.
d. If the switch is has not been moved, the MultiPlus will remain in ‘charger only’ mode and switch to “Float”.
