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
Phoenix Multi 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.
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’.
