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 left panel 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 on the right of the page or restart the device.
Hold down both buttons on the front panel (SELECT
and SETUP/ENTER) for more than 10 seconds (less
than 20 seconds!). All LEDs on the left column shall now
flash. By using these two 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 change. The chosen profile LED
shall then flash. The unit shall then restart and go
through the starting cycle again.
Note
- if you can only see LEDs on the right column the
chances are you are in an error mode. This could be
down to: Very low output voltages (<5V), no output
connection, reverse polarity or the device is not
detecting a valid operational mode as the connector
wire is either not connected or the connection
configuration is wrong. Please refer to previous page.
Left and right meter readings.
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 30 and let go. The LED
columns shall alternatively flash. To confirm factory
default press BOTH buttons again for 2 seconds. Once
confirmed, 3 green LEDs on both columns shall flash.
Then, LEDs on the front panel shall light up in a clockwise
pattern. The unit should then reboot with the default
settings. To reject factory default settings, simply let the
LED columns continue alternatively flashing.
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.
After unit has gone through its startup sequence the
LEDs displayed should be the input voltage on the left
column and the output voltage on the right column.
Also, the top left LED (number 12) should be on solid
which is the fast charge (bulk) LED.

Remember
it is the voltages which are more important
than our battery types. After installation test the voltage
from the unit 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, simply hold down the SETUP
and SELECT buttons for 10-20 seconds and let go. The
LEDs on the left column shall light up. The procedure
hereafter is the same as above.
*Lithium profile has reverse polarity protection
disabled. **All voltages shall be 0.1V higher for the
first 3 minutes of the chargers operation.
