3.3. Configuration of the controller (see figure 1 and 2)
A four pin header is available to select one of three battery management options:
3.3.1. No bridge: BatteryLife algorithm (see 1.2.2.)
3.3.2. Bridge between pin 3 and pin 4: conventional (see 1.2.1.)
Low voltage load disconnect: 11,1V or 22,2V
Automatic load reconnect: 13,1V or 26,2V
3.3.3. Bridge between pin 2 and pin 3: conventional (see 1.2.1.)
Low voltage load disconnect: 12V or 24V
Automatic load reconnect: 14V or 28V
3.4 LED's
Green LED: will be on or blinking when the battery has been connected
On: one of the two conventional algorithms
Blinking: BatteryLife algorithm
Yellow LED: signals charge sequence
Off: no power from PV array (or PV array connected with reverse polarity)
Blinking fast: bulk charge (battery in partially charged state)
Blinking slow: absorption charge (battery charged to 80% or more)
On: float charge (battery fully charged)
3.5 Cable connection sequence (see figure 3)
First: connect the cables to the load, but ensure that all loads are switched off.
Second: connect the battery (this will allow the controller to recognize system voltage).
Third: connect the PV array (when connected with reverse polarity, the controller will heat
up but will not charge the the battery).
The system is now ready for use.
