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 vice versa, 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 the three LEDs “Inverter”, “Charger” and “Alarm” will now flash 5 times.
If a MultiControl panel is connected, on the panel the LEDs “bulk”, “absorption” and “float” will
also flash 5 times.
5. Subsequently, on the MultiPlus the LEDs “Bulk”, “Absorption” and “Float” will each light during
2 seconds.
If a MultiControl panel is connected, on the panel the LEDs “bulk”, “absorption” and “float” will
also each light during 2 seconds.
6. a. If the switch on the MultiPlus is set to “on” while the “Bulk” LED lights, the charger will switch
to equalisation.
Similarly, if the switch on the MultiControl panel is set to “on” while the “Bulk” LED lights, the
charger will switch to equalisation.
b. If the switch on the MultiPlus is set to “on” while the “Absorption” LED lights, the charger will
switch to forced absorption.
Similarly, if the switch on the MultiControl panel is set to “on” while the “Absorption” LED lights,
the charger will switch to forced absorption.
c. If the switch on the MultiPlus is set to “on” after the three LED sequence has finished, the
charger will switch to “Float”.
Similarly, if the switch on the MultiControl panel 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”.
