3. OPERATION
3.1 On/Off/Charger Only Switch
When sw itched to "on", the product is fully functional. The inverter w ill come into operation and the LED "inverter on" w ill light up.
An AC voltage connected to the "AC in" terminal w ill be sw itched through to the "AC out" terminal, if w ithin specifications. The inverter
w ill sw itch off, the "mains on" LED w ill light up and the charger commences charging. The "bulk", "absorption" or "float" LEDs w ill light
up, depending on the charger mode.
If the voltage at the "AC-in" terminal is rejected, the inverter w ill sw itch on.
When the sw itch is switched to "charger only", only the battery charger of the MultiPlus unit w ill operate (if mains voltage is present). In
this mode input voltage also is sw itched through to the "AC out" terminal.
NOTE: When only the charger function is required, ensure that the sw itch is switched to "charger only". This prevents the inverter from
being sw itched on if the mains voltage is lost, thus preventing your batteries from running flat.
3.2 Remote control
Remote control is possible w ith a 3-w ay switch or with a Multi Control panel.
The Multi Control panel has a simple rotary knob w ith which the maximum current of the AC input can be set: see Pow erControl and
Pow erAssist in Section 2.
3.3 Equalisation and forced absorption
3.3.1 Equalisation
Traction batteries require regular additional charging. In the equalisation mode, the MultiPlus w ill charge w ith increased voltage for one
hour (1V above the absorption voltage for a 12V battery, 2V for a 24V battery). The charging current is then limited to 1/4 of the set
value. The "bulk" and "absorption" LEDs flash intermittently.
Equalisation mode supplies a higher charging voltage than most DC consuming
devices can cope w ith. These devices must be disconnected before additional
charging takes place.
3.3.2 Forced absorption
Under certain circumstances, it can be desirable to charge the battery for a fixed time at absorption voltage level. In Forced Absorption
mode, the MultiPlus w ill charge at the normal absorption voltage level during the set maximum absorption time. The "absorption" LED
lights.
3.3.3 Activating equalisation or forced absorption
The MultiPlus can be put into both these states from the remote panel as w ell as w ith the front panel sw itch, provided that all sw itches
(front, remote and panel) are set to "on" and no sw itches are set to "charger only".
In order to put the MultiPlus in this state, the procedure below should be follow ed.
If the sw itch is not in the required position after following this procedure, it can be sw itched over quickly once. This w ill not change the
charging state.
NOTE: Sw itching from "on" to "charger only" and back, as described below , must be done quickly. The sw itch must be toggled such that
the intermediate position is 'skipped', as it w ere. If the sw itch 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 w hen using the front switch on
the Compact in particular. When using the remote panel, this is less critical.
Procedure:
1. Check w hether all sw itches (i.e. front switch, remote switch or remote panel sw itch 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. Sw itch rapidly from "on" to "charger only" and leave the sw itch in this position for ½ to 2 seconds.
b. Sw itch rapidly back from "charger only" to "on" and leave the sw itch in this position for ½ to 2 seconds.
c. Sw itch once more rapidly from "on" to "charger only" and leave the sw itch in this position.
4. On the MultiPlus (and, if connected, on the Multi Control panel) the three LEDs "Bulk", "Absorption" and "Float" w ill now flash 5 times.
5. Subsequently, the LEDs "Bulk", "Absorption" and "Float" w ill each light during 2 seconds.
a. If the sw itch is set to "on" w hile the "Bulk" LED lights, the charger w ill switch to equalisation.
b. If the sw itch is set to "on" w hile the "Absorption" LED lights, the charger w ill switch to forced absorption.
c. If the sw itch is set to "on" after the three LED sequence has finished, the charger w ill switch to "Float".
d. If the sw itch is has not been moved, the MultiPlus w ill remain in 'charger only' mode and sw itch to "Float".
