Starting up the Controller

Self Test
As soon as the controller is supplied with power either from the battery or the
solar array, it starts a self test routine. This is indicated first by running LCD bars
for approx. 0.5 seconds, and then the firmware version is displayed in coded
symbols for about another second (this is for service purposes only). 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 20.0 V, the controller
implies a 24 V system.
If the battery voltage is not within the normal operation range (approx. 12 to
15.5V or approx. 24 to 31 V) at start-up, a status display according to the section
