3. OPERATION
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 specifacations, 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 Multi Control panel.
The Multi 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.
