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.
