On first start up all LEDs will light up. A beep should
sound. The fan shall then start running for around 5
seconds. If, after this, 2 red LEDs flash for 8 seconds
you may have a calibration issue and the unit should be
returned to Sterling. If 2 solid red LEDs are on at the top
or bottom then you either have high or low input voltage
(respectively) - check your voltages.

Changing charging profile during startup

After the initial start up an LED on the first column shall
light up for 5 seconds, this shall indicate the battery type
selected -

default is ‘Sealed’ lead acid

. This is your

window of opportunity to change the charging profile. If
you have missed the opportunity, you can wait for the
unit to go in to normal operation and follow the
instructions immediately below.

Left and right meter readings (BB larger model).

During normal operation

Out of range voltage values

If  voltage  exceeds  the  meter’s  range  the  upper  right
LED shall flash. If the voltage falls short of the meter’s
range  the  lower  LED  shall  flash.  If  two  neighbouring
LEDs, on the voltmeter, are on simultaneously then the
real  voltage  is  between  these  two  parameters.
Example, if LEDs at 14.6V and 14.2V were on then the
approximate voltage shall be ~14.4V.

Low or high output voltages

If the output voltage is below 1V (2V at 24V) or reverse
polarity  then  the  low  output  voltage  LED  will  flash
(number 23). Similarly, if the output voltage is above
15.5V (31.0V at 24V) the high voltage LED shall flash
(number  16).  To  resurrect  these  problems,  bring  the
voltage  above  1V  on  the  output  and  below  15.5V,
correct the polarity and then restart the device.

Return to factory default:

This shall irreversibly

erase all previously entered settings

. Press and hold

both buttons for 8+ flashes and let go. 3 green LEDs on
both columns shall flash. The unit should then reboot with
the default settings.

To view charger’s status:

Simply hold the SELECT button for 1 second and the right
LED should flash indicating the status of the charger. This
shall flash for 8 seconds. To return quickly, press the
SETUP/ENTER button once.

Remember

it is the voltages that are more important than

our battery types. After installation, test the voltage from
the BB is the desired voltage.

Ensure you remove at

least 1 wire from the battery temperature sensor as
the product voltage may be higher (if in cold climate)
or lower (if in warm climate) than the preconceived
voltage.

The voltage requirements of the battery

company will override our recommendations as it is them
who are supporting the battery warranty.

Changing charging profile during operation.

While the unit is running, hold down SETUP button for 10
flashes. All LEDs on the first column shall now flash. By
using both buttons toggle through the various profiles
(see below). The right button is up the column and the left
button takes you down the column. The LED shall light up
demonstrating which profile you have selected. When the
LED has illuminated at your desired profile simply hold
both buttons for a couple of seconds or simply just leave
the charger alone for 30 seconds and it will set the desired
profile. The corresponding LED shall flash to confirm. The
unit shall then restart and go through the starting cycle
again in this new charging profile.

*Lithium profiles have reverse polarity protection
disabled. **All voltages shall be 0.1V higher for the
first 3 minutes of the chargers operation.

If either lithium settings are selected AND the
temperature sensor is connected to the negative terminal
of the lithium battery, the BB shall trip at <0Deg at the
sensor. This can be adjusted in custom profile, or simply
remove temp sensor.
