3. Control and Adjustment
When the charger is installed correctly, the charger should be set up to suit the battery connected.
To set up the charger, apply mains power and enter the setup menu by pressing “SETUP” for three seconds.
The charger will enter a standby mode (no power applied to the battery terminals) and the user can set up the unit accordingly.
See the next table for all possible adjustments.
3.1. Monitor menu
The monitor menu is visible when power is applied to the charger.

After entering the setup menu, the user can scroll through the menu with the up/down keys.
With select a menu item is entered and the present value is shown. With the up/down keys the user can scroll through the available modes or increase/decrease the value.
By pressing select again the value/item is set.
Pressing setup shortly will return to the setup menu.
When setup is completed, exit the menu by pressing “SETUP” again three seconds.
3.3. Battery selection
The charge algorithm of the charger must fit the battery type connected to the charger. The following table shows all the predefined battery types available in the charge algorithm selection menu.

3.4. Power supply mode
The charger can be set to operate as a DC power supply.
In this mode, the charger functions as a constant voltage source:
an adjustable output voltage of 8.0 to 15.9 V (12 V type) resp. 16.0 to 31.8 Volt (24 V type)
a maximum output current of 60A (12 V type) resp. 30A (24 V type).
3.5. Temperature compensation (dV/dT)
The temperature sensor should be connected to the plus or negative pole of the battery.
The temperature compensation is a fixed setting, see table and fig. 4, and applies to all charge states.
The temperature sensor must be installed when:
ambient temperature of the battery is expected to regularly be lower than 15 °C or to regularly exceed 30 °C
charge current exceeds 15 A per 100 Ah battery capacity
Temperature compensation is not required for Li-Ion batteries.
3.6. Power Control – maximum use of limited shore current
A maximum mains current can be set in order to avoid interruption of an external fuse in the mains supply.
