Starting up the controller
Self Test
As soon as the controller is supplied with power from the battery, it starts a self test routine.
Then the display changes to normal operation.
System Voltage
The controller adjusts itself automatically to 12 V or 24 V system voltage. As soon as the voltage
at the time of start-up exceeds 18 V, the controller assumes a 24 V system. If the battery voltage
is not within the normal operation range at start-up, a status display according to the section
ERROR DESCRIPTION occurs.
Battery Type
The controller is preset to operate with lead-acid batteries with solid electrolyte (GEL type or
AGM type). If you intend to use a lead-acid battery with liquid electrolyte, you can adjust the
charging characteristics (see "Settings"). The equalization charge mode is then added. If you
intend to use a LiFePO4 battery, you also can adjust the charging characteristics (see "Settings").
In case of any doubts consult your local dealer.
Recommendations for Use
The controller warms up during normal operation.
The controller does not need any maintenance or service. Remove dust with a dry tissue.
It is important that the battery gets fully charged frequently (at least monthly). Otherwise the
battery will be permanently damaged.
If too much energy is being drawn during the charging process, a battery cannot be fully
charged. Keep that in mind, especially if you install additional loads.
