Introduction to the topic
The first page of the menu »battery-loader« shows an overview of the parameters that you can adjust. You can navigate through the list of parameters using the panel’s arrow keys. Each menu item takes you to a sub-page where you can set the selected parameter between its specified min and max values.
Adjusting absorption voltage and maximum current
Adjusting the absorption voltage
 »Absorption voltage«: Constant charging voltage until the charging current has dropped to the minimum value (parameter »min. current«). |
- Call up the generator menu.
- Select »battery-loader« in the generator menu.
- Select »absorption-voltage«.
- Set the value for the »absorption-voltage« using the arrow keys and confirm with the start/stop key.
NOTE: The value for »absorption-voltage« is 28,4 V. |
- Complete the setting of the value for the »absorption-voltage« with »confirm«.
Adjusting the maximum current
»Maximum current«: Maximum charging current flowing to the battery. |
- Call up the generator menu.
- Select »battery-loader« in the generator menu.
- Select »maximum current«.
- Set the value for the »maximum current« using the arrow keys and confirm with the start/stop key.
NOTE: The value for »maximum current« is dependent on the generator type. |
- Complete the setting of the value for the »maximum current« with »confirm«.
Calibrating voltage and current
You can calibrate the panel displays of the DC generator for voltage and current to the measured values.
NOTE: The calibration of voltage and current for DC generators must be done in L2! |
- Start the generator.
- Call up the service menu.
- Enter admin password.
- Return to the panel menu with »back«.
- Call up the factory menu.
NOTE: If a current greater than »0 A« is displayed on the panel when idling, the value must be calibrated to »0 A« using the option »PH2: calibr. 0-curr« in the factory menu. |
- Select »calibrate 3PH« for the measurement unit.
- Select »PH2: calibr. 0-curr« and confirm.
- Select »voltage (L2)«.
- Measure the voltage.
- Set the value to the measured voltage using the arrow keys and confirm with the start/stop key.
- Select »current (L2)«.
- Set the current to the measured value using the arrow keys and confirm with the start/stop key.
Appendix
Controls
| Hardkey | Function |
 | “Increase parameter value” key. A long press on the button activates the rapid increase of the parameter value. |
 | “Decrease parameter value” key. A long press on the button activates the rapid decrease of the parameter value. |
 | “Confirm parameter value” key. |
Parameters
| min. voltage [V] | Battery voltage at which the battery charger is started automatically. |
| absorption voltage [V] | Constant charging voltage until the charging current has dropped to the minimum value (parameter min. current). |
| float-voltage [V] | After charging the battery, the float-voltage ensures that the fully charged state of the battery is maintained for the duration of the “float-timeout”. |
| min. current [A] | If the charging current goes below its minimum value, the battery is fully charged. At this point the hysteresis starts until the switchover to the float voltage. |
| max. current [A] | Maximum charging current flowing to the battery. |
| hysteresis [ms] | Time T, until the control switches from voltage to current control and vice versa, to prevent constant switching between voltage and current control. After this time is switched to the maintenance voltage. |
| battery guard [On/Off] | “On” – enable battery guard, automatic generator start / stop is enabled. The generator is started automatically when the battery voltage drops below its minimum (parameter min. voltage). “Off” – disable battery guard, automatic generator start / stop is disabled. |
| float-timeout [min] | After termination of the float-timeout, the generator is stopped automatically if the battery guard is activated. |
| mode | BMS, UIU |
| voltage droop [V] | the decrease in voltage output as the load (current draw) increases |
