INSTALLATION OF STERLING BATTERY CHARGER acid/traction batteries for standard marine use, as there ability to top up the liquid level
Position the charger in a cool dry well ventilated space, ensuring a reasonable airflow increases there charge rate and life expectancy and we strongly recommend you stay
around the charger. Do not install in a cupboard or sealed compartment. away from gel or A.G.M.as there charge rate is very limited.
This charger has many new features including the ability to compute the battery size
and state, so it is no longer necessary to program that information into the unit (as per

Before switching on the charger it is important to set up the battery type, please choose
a battery type from above. The highest charge rate (and voltage) will be the open lead
acid (set to a 14.8 volts on high charger) then gel (set at 14 .4 volts) then advanced glass
matt (set at 14.1 volts).
If the battery type requires to
be reprogrammed, then select the appropriate setting on the dip switch and ensure the
charger is switched off then on again for the settings to take effect (this is because the
internal software chip requires a re-boot to install the new settings). The settings have
not taken effect if the L.E.D has not changed to the correct colour. In the event of
different types of batteries then the lowest battery voltage type must be selected, never
charge a battery on a higher setting than it should, Sterling recommends open lead
This unit is fitted with an automatic 110/230 volt crossover as such the following
voltage may be used (90-125 or 190-260 volts at any frequency (40-400 Hz))
Always connect the cables to the charger first then run them to the batteries, never
connect to the batteries and run to the charger.
Warning, the charger case is earthed as per international regulations, on most boats the
A/C earth is connected to the bonding system and then to the negative of the battery,
this means that the case could be negative. If you touch the positive battery cables to
the case then you can set up a dead short to the battery negative via the earth cable and
melt the earth cable, this could start a fire. To avoid this, ensure the battery connectors
on the output studs do not touch the charger case, use insulated output connectors, it is
also recommended by A.B.Y.C. regulations that all the charger outputs have a fuse
connected. We recommend the Sterling gold range GMFB 4848, which offers a 4-bank
fuse block, which can be fused from 20-80 amps.
( the agm and gel voltage tends to vary with company to
company, so check which voltage your batteries require )

What information the L.E.D. display is giving you
:this L.E.D. is a 3 coloured L.E.D. which means it has 2 colours inside it (red and green). Either colour is used
separately or when both are on they look yellow. It is very important to ensure that the L.E.D. colour displayed conforms to your battery
type, if you have a mixture of lead acid and gel then the setting must be for the gel (the worst case, i.e. the gel can only handle 14.4 volts
but the lead acid can go to 14.8. so it is important not to exceed 14.4). This L.E.D. should be set as per the dipswitch instructions above.
this L.E.D. indicates that the charger has tripped out due to either the chargers own regulator has failed, or an
external source is over charging (such as a solar cell, or wind generator, or engine alternator) and the charger thinks it has failed.
High charger temp: This shows that the charger has tripped because the heat sink is to hot, check if the fans are working. The unit will
restart when the heat sink reduces in temp.
The charger has switched off because it has picked up a battery temperature in excess of 50 deg C, investigate
your batteries immediately, and check the water levels. There is a serious problem, do not restart the charger until a fault has been found.
On reset monitor the temperature either from the remote or by simply keeping an eye on the batteries for the first few days.
(This L.E.D. can look red but is in fact orange) this shows the unit is on constant current mode on start up,
and should remain on until the high charge cycle is complete (between 1 - 8 hrs max).
Time Control ( yellow ): This L.E.D. comes on between 6 minutes (minimum) and about 1 hr max, this indicates that the chargers timer
has started and the count down will be displayed on the remote control (if used). This timer light will remain on with the above orange
L.E.D until the end of the high charge cycle, when they both will go off and the lower green will come on.
This means its all over as far as the fast charging is concerned, however the unit is now in power pack mode,
and will remain at about 13.5 volts float and supply your system any power it required up to its maximum power.

Example, a boat could be moored all year and never leave the pontoon, or a stand by generator with the
charger on all the time. In these cases the de-sulphation cycle would only happen once and the batteries
would eventually sulphate causing premature destruction. However the Sterling software has a 7 day
timer which in the event of inactivity will automatically run a de-sulphation cycle keeping your plates
clean.
In order to meet C.E. requirements for Radio Frequency Interference a three-stage filter is used to ensure
that not only is the standard reached but also that we fall well above the standard legally required.
The Sterling Digital comes complete with a battery temperature sensor, which is automatically set to one
of the temperature compensation set by your battery type selector switch.
The larger battery charger range comes complete with 3 temperature
sensors, which monitor and display and react to the 3 different battery banks, including 3 high temp trips
This unit has a trip circuit which can be
connected to any trip device such as temperature trips or any trip which results in an open circuit. The
problem is that a charger could be attached to 10 batteries but only monitoring 3, however if you wish
you can put a standard temperature trip on every battery and link them together into a common trip
circuit, if any of these batteries exceed a pre determined value the charger will switch off.
Things do go wrong no matter how hard we try so in the event of the regulator control failing, then any
voltage above what the software is expecting will shut the battery charger down and display the fault.
It always amazes me how many companies sense battery temperature and compensate the charger
voltage against temperature, but in the extreme event of total battery failure and the battery is going to
boil the battery charger will not switch off the charger. The Sterling processor not only senses the
temperature but will shut down the charger in event of total failure and display the fault condition.
In the event of extreme temperature or cooling fan failure the battery charger will switch off at 70 deg C
Because it is best to get as much power as possible at high temperature, in extreme high temperature or
cooling fan failure, if the heat sink reaches 65 deg C then the output current of the unit will be
systematically reduced to prevent the high temperature trip being activated at 70 deg C, its better getting
something than nothing.

Because the largest market for our products is in the USA, it is important to conform to European and

some electricians were receiving electric shocks because they thought they were on the D/C negative
system when they were on the 110V A/C system (guaranteed to waken you up first thing in the morning)
.as a result international regulation bodies are attempting to change the colour of the D/C negative
cables (which have been black) to yellow, this is already the case in the U.S.A. for A.B.Y.C. and is under
review in the U.K. The negative cable in the new digital range comes as yellow and a gold fuse is
supplied.
The supplied fuse blocks offers a good reverse polarity protection system.
