3. OPERATION – inverter/charger
3.1 On/Off/Charger Only Switch
When switched to 'on', the product is fully functional. The inverter will come into operation and
the LED 'inverter on' will light up.
An AC voltage connected to the 'AC in' terminal will be switched through to the 'AC out'
terminal, if within specifications. The inverter will switch off, the 'mains on' LED will light up
and the charger commences charging. The 'bulk', 'absorption' or 'float' LEDs will light up,
depending on the charger mode.
If the voltage at the 'AC-in' terminal is not within specifications, the inverter will switch on.
When the switch is switched to 'charger only', only the battery charger of the MultiPlus will
operate (if mains voltage is present). In this mode input voltage also is switched through to the
'AC out' terminal.
NOTE: When only the charger function is required, ensure that the switch is switched to
'charger only'. This prevents the inverter from being switched on if the mains voltage is lost,
thus preventing your batteries from running flat.
3.2 Remote control
Remote control is possible with a 3-way switch or with a Digital Multi Control panel.
The Control panel has a simple rotary knob with which the maximum current of the AC input
can be set: see PowerControl and PowerAssist in Section 2.
For the appropriate DIP switch settings, see sect. 5.5.1.
3.3 Equalisation and forced absorption
3.3.1 Equalisation
Traction batteries may require regular equalisation charging. In the equalisation mode, the
MultiPlus will charge with 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 with. 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 will charge at the normal
absorption voltage level during the set maximum absorption time. The 'absorption' LED will be
'on'.
