PROGRAMMING
Before any use, make sure the correct battery type is set! This is a list of common batteries from the lead-acid
chemistry family;
Conventional wet flooded cell. Also simply known as “Lead Acid”. This type will have screw-out vents
for maintenance and topping up with distilled water. For this type use the
AGM/Wet
setting.
Sealed Maintenance Free (SMF). This type still has a liquid acid inside (if you rock it from side to side
you will hear it ‘slosh’ and move) but is not able to be opened for topping up. This type commonly has a
“Magic Eye” for telling the state of charge too. Use the
Calcium
setting for this battery type.
Absorbed Glass Mat (AGM). A common type of fully sealed and maintenance free battery used in a lot
of camper-vans, caravans, motorhomes & boats as they emit no toxic fumes during normal use. Use
the
AGM/Wet
setting for this type of battery.
Gel. The original sealed battery type uses silica-dioxide to fix the acid in place. They can be difficult to
identify and can be easily mistaken for an AGM battery. Use the
GEL
setting for this type.
IMPORTANT! If you are unsure of your battery type, check with your battery supplier or the battery
manufacturer. Using the wrong setting can damage your battery and will not be covered under
warranty.
AUTOMATIC POWER-SUPPLY MODE
This charger will automatically become a power supply in the event there is no battery connected or there has
been a total battery failure. This allows you to use critical loads such as a water-pump in a remote area where
no replacement may be available.
If there has never been a battery installed in your camper-trailer, caravan, etc you must have this unit plugged
into AC mains to be able to operate the lights, TV, etc.
If you decide to install a battery at a later stage, you do not need to purchase another charger. Simply have a
suitable battery installed by a professional automotive-electrician and check the
Battery Type
is set correctly.
If you have a battery installed and suspect there has been a battery failure of any kind, this feature will allow
you to still be able to operate your DC loads such as lights and TV because the charger will still turn on when
the battery has been disconnected and/or removed.
If this happens, disconnect the AC mains and have an automotive-electrician to disconnect the battery
Negative terminal and then secure and insulate the cable so it cannot short-circuit or make contact with
anything.
When AC mains is re-applied with no battery connected, the charger will automatically restart as a Power
Supply. This is shown by the
Float/PS
LED coming on.
When the problem is fixed or faulty battery is replaced, it will automatically restart as a Battery Charger.
USE WITH OTHER CHARGING SOURCES
It is quite common in installations where this charger will be used to have other methods of charging the
batteries also connected (and possibly in use) at the same time. Because this charger is has been designed as
a voltage regulated product, there is little chance of this being a problem. Most alternators, solar controllers,
DC-DC chargers, etc will not cause any ill-effect if used at the same time. However, we recommend that you
check with the other equipment suppliers if you are not sure.
STORAGE
This charger has been designed to be left permanently connected.
We therefore recommend that you plug the charger into AC mains when your camper-trailer, caravan, boat, etc
is in storage so that the battery is always maintained at 100% state of charge and always ready for use.
If you don’t have access to permanent AC mains power, consider solar panels and a suitable regulator (such
as the Ozcharge OCSR30) to keep the battery fully charged.
Keep in mind that all batteries have a certain rate of “self discharge” and will eventually go flat by themselves,
so we recommend the charger be left connected to AC mains when not in use.
