Polarity Protection
This allows the charger protection if there is a reverse connection or short circuit
and stops any sparking from the output leads.
Note: This feature is not available in Power Supply mode where a battery should not
be connected.
Over Temperature Protection
A three-phase temperature protection system has been installed for your safety.
These are:
a. if increased temperature is detected a cooling fan will be started;
b. if cooling fan fails to be sufficient, power output is reduced; and
c. if temperature is detected as too high due to an excessive ambient temperature
(greater than 50°C), the charger will shut down.
BC25 Battery Temperature Sensor
The temperature sensor monitors the temperature of the battery. Charging voltage
will adjust depending on the temperature of the battery. Place the sensor as close to
the battery as possible.
Cooling Fan
A cooling fan ensures that your charging unit is maintained at optimum performance
temperature and is automatically engaged should the internal temperature exceed
the required limit. Ensure there is adequate clearance and ventilation around
the unit so that heated air can escape and cool air can enter to ensure optimal
performance of the unit.
DISPLAY
The BC15 and BC25 have an informative LED interface.
The top row has 6 green LEDs indicating the stage of the charge cycle.
See “7 Stages of Charging”. The first LED may also be red if a fault condition is
present. See Fault Codes.
The second row, 4 green LEDs indicates the Battery Chemistry selected. See step 5
of “Charging Instructions” and “Battery Chemistry Selection” sections.
The third row, 3 green LEDs indicate the Battery Charge Rate selected. See Step 4
of “Charging Instructions” and “Adjustable Charge Rate” sections. In Power Supply
mode the 3rd LED is illuminated Orange. See “Power Supply” section.
