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 modus is added then. 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.
Display Functions in normal operation
The controller is equipped with 5 LEDs and an acoustic warning signal.
