CHARGE CURVE SELECTION
The digital electronics, based on an RSC microcontroller,
monitor the charging process by optimizing, the voltage,
current and recharging time parameters. This is based on
the initial charge level of the batteries, using the
exclusive “scanning charge” function.

13
The performance and usable life of batteries are thereby maximized.
By virtue of fully automated charging cycles, the batteries are protected against
surges, providing a permanent connection for the charger.
Selection of the charging Program takes place on installation using the
“CHARGE SELECT” dial on the charger board.
The position of the arrow indicates the number of the Program selected (e.g.:
Program No. 1 in the photograph above). Selection is made using a small flat-
head screwdriver.
CAUTION
It is important to note that the use of an inappropriate charging cycle for
the battery technology may extensively impair or even damage the
latter.
This is particularly true for cycles where charge voltages are higher than the
levels recommended by the battery manufacturers.
A serious risk of overheating the batteries and releasing gases that are
harmful to users’ health.
Curve no. 9 is compatible with a LiFeSo4 battery, provided that the battery is
equipped with BMS-type battery Protection (Battery Management System)
within the actual battery. In this case, refer to the battery manufacturer’s
recommendations for the choice of charging cycle.

OPERATION of BATTERY TEMPERATURE SENSOR
The temperature sensor allows the charging voltage to be
automatically adjusted depending on the battery and ambient
temperature.
This function increases battery life, by reducing output voltage and current
due to high ambient and/or battery temperature.
This sensor is screwed onto the main battery’s positive terminal (a
service/house battery as a general rule). The 2 wires are connected to the
“TEMP SENSOR” connector on the charger board (not polarity sensitive).
The compensation level is around
+/-25mV per °C for a 24V battery and between +/-12mV per °C for a 12V
battery (see curves below).
Reference voltage
Battery temperature in °C
The temperature sensor initially simulates a temperature of 77⁰F (25°C). The action of the
battery temperature sensor allows the charge to be adjusted, upwards or downwards,
depending on the battery temperature, i.e.:
+/- 15 mV per °C at 12 V
+/- 30 mV per °C at 24 V

17
LED DISPLAY
The Voyager Elite charger is equipped with a local multifunction LED display,
which, among other things, shows the details of the key stages of the battery
charging process.
BOOST phase: The battery is in its recharging phase, reaching a level of charge of
close to 80%. This recharging phase is limited to a period of
6 hours.
ABSORPTION phase: The voltage is maintained and the amperage is reduced
until the battery returns to a level of charge approaching 100%. This phase is
limited to a period between 30 minutes and 4 hours, depending on the
battery’s initial charge level.
FLOAT phase: The voltage and the amperage are reduced to maintain the
battery at 100% full charge. During the Floating phase, the charger only delivers
what the battery requires to prevent overcharging.
Fault Indicators: The Temperature (TEMP), Battery (BAT) and fuse (FUSE) fault
indicators are shown on the LED display.
