Phocos CXN Bedienungsanleitung Seite 34

Be aware that theCXN is negative grounding and the negative terminals of the
CXN controller are connected internally and therefore have the same electrical
potential. If any grounding is required, always do this on the negative wires.
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
ERROR DESCRIPTION occurs.
Battery Type
The controller is preset to operate with lead acid batteries with liquid electrolyte.
If you intend to use a VRLA battery (GEL type) you can adjust the controller in
Programming Menu 1 (see back page). The equalization charge is deactivated
then. In case of any doubts consult your dealer.
