INSTRUCTION MANUAL
WARNING: BEFORE USING THE BATTERY CHARGER READ THE
INSTRUCTION MANUAL CAREFULLY.
1. GENERAL SAFETY RULES WHEN USING THIS BATTERY CHARGER
- During the charge the battery produces explosive gases, avoid the
formation of flames and sparkes. DO NOT SMOKE.
- Position the batteries to be charged in a well-ventilated place.
- Inexperience and untrained people should be properly instructed
before using the appliance.
- People (children included) whose physical, sensory or mental
capacities would prevent them from using the appliance correctly
must be supervised by a person who is responsible for their safety
while the appliance is in use.
- Children must be supervised to ensure that they do not play with
the appliance.
- Use the battery charger only indoors and make sure that you start it in
airy places. DO NOT SET IN THE RAIN OR SNOW.
- Disconnect the mains cable before connecting to or disconnecting the
charging cables from the battery.
- Do not connect or disconnect the clamps to or from the battery with
the battery charger operating.
- Never use the battery charger inside the car or in the bonnet.
- Substitute the mains cable only with an original one.
- Do not use the battery charger to charge batteries which are not
rechargeable.
- Make sure the available power supply voltage corresponds to that
shown on the battery charger rating plate.
- To avoid damaging the vehicle’s electronics, read, keep and take very
careful note of the information supplied by the vehicle manufacturer,
when using the battery charger either for charging or starting; the
same applies to the instructions supplied by the battery manufacturer.
- This battery charger has components such as switches and relays
which can cause arcs or sparks. Therefore when using it in a garage or
in a similar place set the battery charger in a suitable case.
- Repair or maintenance of the inside of the battery charger can be
executed only by skilled technicians.
- WARNING: ALWAYS DISCONNECT THE POWER SUPPLY CABLE
FROM THE MAINS BEFORE CARRYING OUT ANY SIMPLE
MAINTENANCE OPERATION ON THE BATTERY CHARGER.
- Make sure the power outlet is protected by an earth connection.
- For those models without one, connect a plug with suitable capacity in
relation to the fuse size shown on the data plate.
2. INTRODUCTION AND GENERAL DESCRIPTION
- This battery charger can be used to charge free electrolyte lead acid
batteries used on petrol and diesel engine vehicles, motor cycles,
boats etc.
- Rechargeable batteries according to the output voltage available: 6V /
3 cells; 12V / 6 cells; 24V / 12 cells.
- The charger case has a protection degree of IP 20 and is protected
against indirect contacts by an earth lead as required for class
equipment.
3. INSTALLATION
ASSEMBLY (FIG.A)
- Unpack the battery charger and assemble the separate parts contained
in the package.
- Models on wheels are to be set in a vertical position.
POSITIONING THE BATTERY CHARGER
- During operation, position the battery charger on a stable surface
and make sure that there is no obstruction to air passage through the
openings provided to ensure sufficient ventilation.
CONNECTION TO THE MAIN SUPPLY
- The battery charger should be connected only and exclusively to a
power source with the neutral lead connected to earth.
Check that the mains voltage is the same as the voltage of the
equipment.
- Check that the power supply is protected by systems such as fuses or
automatic switches, sufficient to support the maximum absorption of
the equipment.
- The connection to the main supply has to be made using a suitable
cable.
- If you put an extension to the primary cable, the section should be
adequate and, in any case, never less than that of the cable supplied.
- You always have to earth the equipment with the yellow/green wire
contained in the main cable, indicated by the label (
), while the
other two wires should be connected to the mains.
4. DESCRIPTION OF THE BATTERY CHARGER
This model is a battery charger / starter that is electronically controlled
by a microcontroller.
As regards adjustment and indicators there are (FIG. B):
1- Main switch 0/OFF - I/ON (lit).
2- Selector switch LOAD, STARTER
3- Positive sockets 12V / 24V.:
4- Direct negative output.
5- Potentiometer for adjusting charge current:
the setting is shown on the display for a few seconds, during charging,
every time the potentiometer knob is turned (during adjustment LED
“ I “ also flashes).
6- Key for selecting battery voltage 12V /24V.
7- Key for selecting I / V parameter to be shown on the display:
- V = voltage in volts
- I = current in amps.
8- Key for selecting operating mode - TEST, CHARGE, TRONIC:
- TEST charging off.
In this mode it is possible to check the voltage and state of the
battery (with alternating parameters shown on the display FIG.C).
The battery charger is also able to indicate whether the connection
with the 12V / 24V charging terminals is compatible with the
selection corresponding to the 12V / 24V key.
If there is an error in the connection or the setting the display will
show the flashing message “Err” until the problem has been solved.
NOTE: The user can exclude this protection (for details see the
section SAFEGUARDS).
- CHARGE charging on.
This is used to charge the battery or batteries at constant current
depending on the setting and in any case in relation to the battery
capacity (Ah).
When the battery has reached a set voltage level at the end of
charging this will be maintained over time.
Moreover, if the battery voltage is particularly low the charger
supplies a fixed current of about 2A until it reaches the safety
voltage of 1.5 volts per element. Under these operating conditions
the display shows the fixed current value alternating with “LCC”.
NOTE: The user can exclude this protection (for details see the
section SAFEGUARDS).
- TRONIC automatic charging on.
This is used to charge the battery or batteries automatically in the
same way as above but with preset voltage thresholds.
9- Display for showing the selected parameter. The display also shows a
number of abbreviations relating to the present status/mode (FIG. D).
5. OPERATION
BEFORE CHARGING
NB: Before charging check that the capacity of the battery (Ah) which
is to be charged, is not inferior to that reported on the data table.
(C min).
Follow the instructions, taking great care to respect the order given
below.
- Remove the caps of the battery charger (if foreseen) so as to let the gas
produced go out.
- Check that the level of the electrolyte covers the plates of the battery. If
these were not covered add distilled water and cover them up to 5 - 10
mm.
WARNING: USE THE MAXIMUM CAUTION DURING THIS
OPERATION AS THE ELECTROLYTE IS A HIGHLY CORROSIVE
ACID.
- Please remember that the exact charge status of the battery can only
be determined by using a densimeter which allows measurement
of the specific gravity of the electrolyte the following indicate
approximate density values for the solute (Kg/l at 20°c):
