2.1 Settings – General
Settings may be changed with the aid of pushbuttons and dip switches (see Appendix A).
Dipswitches are used to activate set-up, and to determine the setting to be changed. The
value of this setting can be changed with the aid of the pushbuttons.
The value specified is shown on the LEDs. Sections 2.1.3 and 2.1.4 describe how the LEDs
can be read.
2.1.1 Default Settings
To restore the default settings, both pushbuttons should be held down for 3 seconds while
set-up is activated.

2.1.2 Reading LEDs – setting values (Multi/ MultiPlus only)
The value of a setting can be determined on the basis of the following formula:
Value set = setting number * scale + offset
The ‘offset’ and the ‘scale’ are specified for each setting.
The setting number is indicated as follows via the LEDs:
The LEDs are divided into 2 columns of 4 LEDs each.
Each column indicates the numbers 0 - 9.
These columns together indicate 2-digit numbers.
The left column indicates the left-hand digit. The right-hand column shows the
right-hand digit.
The digit in a column can be determined by adding the separate ‘LED values’.
A flashing LED counts as 1 and an illuminated LED as 2.
A special case is 4 flashing LEDs. This signifies a 9.
Symbol Meaning LED value
LED off 0
LED flashes 1
LED lit up 2
All LEDs in a
column are
flashing
9
Examples of setting numbers:
0 0 0 1 0
0 2 0 2 0
0 2 2 2 1
0 2 2 2 2
0 6 =6 4 7 =47 3 9 =39
The increments can be smaller than the reading (scale value). In that case, a pushbutton
should be pressed repeatedly before the LED indication changes.

8
2.1.3 Reading LEDs – on-off (Multi/ MultiPlus only)
In addition to the facility of setting a value, there is an on- off facility. This allows for
switching on/ off a particular setting, or for activating/ deactivating it. The left-hand column
offers possibility A and the right-hand column offers possibility B in the case of a dual choice
setting.

Charging Characteristics
The Phoenix Multi/ MultiPlus has 3 pre-programmed charging characteristics.
Fixed Charging Characteristic:
The absorption period is a fixed preset period. Following the absorption mode, the charger
switches to float. In order to “refresh” the battery, the charger periodically switches back to
absorption.
Adaptive Charging Characteristic:
The absorption period depends on the charge delivered during bulk. This is followed by float
phase lasting 24 hours, after which the voltage is reduced by an additional 0,8 V resp. 1,6 V
for 12 V resp. 24 V batteries. (reduced float). As with the Fixed-charging characteristic, the
charger will periodically switch back to absorption.
Adaptive Charging Characteristic with batterySafe mode (default setting):
If, in order to quickly charge a battery, a high charge current in combination with a high
absorption voltage has been chosen, the Phoenix charger will prevent damage due to
excessive gassing by automatically limiting the rate of voltage increase once the gassing
voltage has been reached

2.5 Special Settings
Bulk Protection On/ Off
If the charger has not reached the absorption voltage after 10 hours' charging in the bulk
phase, the battery may be defective. In order to prevent further damage, the charger will
automatically cut out after 10 hours' bulk. The “bulk” LED will start to flash.
This safety cut out can be switched off.

PowerControl – Dealing with limited generator or shore side power
The Multi is a very powerful battery charger. It will therefore draw a lot of current from the
generator or shore side supply (nearly 10 A per Multi at 230 VAC). With the Phoenix Multi
Control Panel (PMC) a maximum generator or shore current can be set. The Multi will then
take account of other AC loads and use whatever is extra for charging, thus preventing the
generator or shore supply from being overloaded.
It is also possible to set the max. generator/ shore current internally.
.
The generator/ shore current can be set at 1 - 30A.

PowerAssist – Boosting the capacity of shore or generator power
The feature that distinguishes the Phoenix MultiPlus from the standard Multi is PowerAssist.
This feature takes the principle of PowerControl to a further dimension allowing the
MultiPlus to supplement the capacity of the alternative source. Where peak power is so
often required only for a limited period, it is possible to reduce the size of generator needed
or conversely enable more to be achieved from the typically limited shore connection. When
the load reduces, the spare power is used to recharge the battery.
Note: minimum shore current 4 A or generator capacity 2,5 kW required per MultiPlus.
