1.4 Error Codes
In the event of a fault with the unit installation, either battery or solar panel, ALL
the LEDs on the unit will flash to indicate the fault type. Flashing sequences are
described in the table below.
LED State Description
1 flash (1 flash followed by 3.5 second off) Internal Hardware Fault
2 flash (2 flash followed by 3.5 second off) Reserved
3 flash (3 flash followed by 3.5 second off) Unit over temp fault
4 flash (4 flash followed by 3.5 second off) Output Battery Fault (Volts too high) /
Solar Panel connected reverse polarity
5 flash (5 flash followed by 3.5 second off) Input under voltage (Battery)
6 flash (6 flash followed by 3.5 second off) Input over voltage (Battery or Solar panel)
7 flash (7 flash followed by 3.5 second off) Reverse polarity
NOTE: The unit will operate optimally below 55°C with good airflow. At higher
temperatures the unit will de-rate output current.
NOTE: Appropriate connections must be made to the wires with a continuous current
rating of at least 25A for the BCDC1225(-LV) or 40A for the BCDC1240(-LV). Failure to
do so may cause damage to the unit and vehicle.
2 INSTALLATION
Mount the unit to a flat surface close to the auxiliary
battery and away from any heat sources. The
BCDC1225(-LV)/BCDC1240(-LV) has 6 wires and
should be installed as described over the following
pages.
2.1 RED wire - Input Source Positive
The RED wire should be connected to the positive input
from the source - this can be either from a vehicle’s
starter battery or from a solar panel.
Appropriate size fuses should be used as per the
specifications table on page 2.
