FAULT FINDING
HELPFUL HINTS
Should the charger appear to be malfunctioning we suggest the
following to eliminate any external problems.
1. Turn the charger OFF by disconnecting the AC plug and switching
the circuit breaker OFF to disconnect from the batteries.
2. Disconnect all DC battery leads. Clean all terminals by removing all
grease/corrosion on both leads and battery terminals.
3. Reconnect all leads and terminals and ensure all connections are
tight.
4. Turn the charger ON via the AC plug and DC circuit breaker on the
front panel. Observe the lights on the front panel for status and
mode of operation. Refer to charger operation section for full
explanation of indicators.
- If battery voltage is below 6V for 12V Charger or below
12V for 24V Charger, this will show as battery fault condition and
will not charge.
Note
* Make sure Green led comes ON when AC plug is connected and
turned ON. If Led is OFF check AC fuse.
* When the DC Circuit Breaker is turned ON, check that neither of
the Battery fault or reverse polarity indicators are flashing.
* Make sure terminals and leads are not corroded or faulty in
any way.

BATTERY SIZING
SAFETY
To ensure optimum performance, it is important to match the charger size
according to the capacity of your batteries. Use this formula as a general
guide:
Approx. Charger Size = Battery AH capacity ÷ 10
e.g. 300 AH ÷ 10 = 30A Charger
Minimum Battery size = 100 AH
Battery terminals require frequent care and maintenance. We recommend an
inspection of the batteries and the interconnecting cable connections once
every 1-3 months or as recommended by the battery manufacturer.
1. Regularly check all connections; make sure they are always tight.
Battery terminals are made of soft lead which will slowly compress over
time eventually causing loose connections.
2. Check all connections are free of corrosion. Remove any corrosion
the terminals with Vaseline or grease to help prevent future
corrosion.
3. Take specific gravity or SG readings of each cell using a hydrometer to
check the level and performance of each battery. Alternatively a
battery voltage reading for each cell will suffice but may not be
accurate for multiple batteries connected in parallel. Report any serious
imbalance to your system installer or battery supplier for corrective
action.
When working on batteries protective clothing and eye wear should be worn.
Extreme care should be taken not to short circuit any battery terminals
especially with tools. If in doubt have the work carried out by qualified
personnel.
