5.3. Deep Discharging Protection
The regulator protects the connected battery against an excessive discharging. If the bat-
tery falls below a specified charge level (during SOC control) or battery voltage (during
the voltage-controlled function), the load output is disconnected and the discharge of
the battery is prevented. The display shows the early warning and disconnection during
deep discharging. The setpoints of the deep discharging protection are predefined and
cannot be reset.
6. Regulator Settings
The battery type, control type and night light function can be set in the regulator. Points
for the auto-test and the serial number query are also located within the menu. The set-
tings remain when the battery is disconnected.
6.1. Calling up and Modifying the Settings
Press the left button for at least 3 seconds to open the first setting window (control
type). Press the left button again to call up the various windows.
Press the right button to modify settings. The display begins to flash. Now, with the left
button select the settings options. The setting must be saved with the right button. The
display then stops flashing.
The normal window reappears after a 30 second waiting period or pressing the left but-
ton for 3 seconds. This applies to all windows.
6.2. SOC Setting / Voltage Control
The SOC control is the factory setting. This way, the charging procedure and the deep
discharging protection are controlled by the calculated SOC value for ideal battery
usage. If external loads are connected directly to the battery you can change to voltage
control. The bar
gauge can then be
enabled or disabled.
See chapter 10 for
voltage thresholds.
6.3. Gel / Liquid Battery Type Setting
The standard setting is “Li”. The setting
of the battery type influences the cutoff
voltage of the controller. If you use a Gel
or AGM battery, you have to change the
battery type to GEL.
Caution! An incorrect battery type setting can damage the battery!
