- With models having more than one charge voltage, turn the deviator or
the switch to the selected charge voltage. If there is no deviator or switch,
suitably connect the red crocodile clip (+ symbol) to the specic battery
charger terminal in correspondence with the selected charge voltage.
- Connect the red charge clamp to the positive terminal of the battery ( +
symbol). If the symbols are indistinguishable remember that the positive
terminal is the one not connected to the vehicle chassis.
- Connect the black charge clamp to the vehicle chassis, at a safe distance
from the battery and the fuel pipe.
NOTE: if the battery is not installed in the vehicle, connect the clamp directly
to the negative terminal of the battery (- symbol).
6.3 MANUAL CHARGING AND AUTOMATIC CHARGING
NOTE: the Ah values, if given beside the pushbuttons, are purely indicative
(because the charging process depends on how at the battery is) and they
suggest the position for charging an initially at battery with capacity within
the indicated range, in under 15 hours. It is not advisable to go below the
minimum values that are indicated.
6.3.1 MANUAL CHARGE (
)
Recommended method for free electrolyte lead acid batteries (WET).
- Carefully follow the instructions given in paragraphs 6.1 and 6.2.
- Move the deviator (if present) to the BATTERY symbol.
- Turn the charge adjustment deviator/deviators or switch (if present) (FIG.
C) the normal charge position (BATTERY symbol) or fast charge position
(BOOST) as required (with some models the switch also acts as a power
switch).
- If the battery charger has a TIMER a maximum pre-set charge time can be
set (FIG. C).
- Power the battery charger by inserting the power supply cable into the
power outlet and turning the switch (if present) to ON.
- Monitor the ammeter as described in paragraph 4.
NOTE: Once the WET battery is charged, you may note the liquid inside
starting to “boil”. It is advisable to stop charging when this phenomenon
appears so as to prevent damage to the battery.
6.3.2 AUTOMATIC CHARGING (TRONIC)
We recommend using models with the TRONIC mode to charge sealed
batteries (GEL, AGM).
- Carefully follow the instructions given in paragraphs 6.1 and 6.2.
- Turn the deviator to TRONIC and the charge adjustment switch to the
normal charge position (BATTERY symbol) or fast charge position (BOOST)
as required (FIG. C).
- Power the battery charger by inserting the power cable into the mains
socket. The battery charger controls the voltage present at the battery
terminals, automatically interrupting the current being supplied when
the battery is charged (the ammeter indicator positions itself at zero)
and supplying it again automatically when the battery begins running
down. The TRONIC mode is ideal for automatically maintaining the battery
charged (AGM and WET) without the risk of damaging it.
6.4 SIMULTANEOUS CHARGING OF SEVERAL BATTERIES
WARNING; do not simultaneously charge dierent types of batteries or
batteries with dierent capacities or levels of discharge. If you have to
charge more than one battery at the same time you can connect them
“in series” or “in parallel” (FIG. D).
For “parallel” connection batteries must have the same nominal voltage
(Volt), which corresponds to the battery charger output voltage, and the
total of Ah must be within the charge range of the battery charger.
For “serial” connection batteries must have the same capacity (Ah) and the
sum of the nominal voltages of all the batteries must correspond to the
battery charger output voltage.
6.5 END OF CHARGE
- Remove the power supply from the battery charger by turning the switch
to OFF (if present) and/or removing the power supply cable from the
mains outlet.
- Disconnect the black charge clamp from the chassis of the vehicle or from
the negative terminal of the battery (- symbol).
- Disconnect the red charge clamp from the positive terminal of the battery
(+ symbol).
- Store the battery charger in a dry place.
- Close up the battery cells with the appropriate plugs (if present).
6.6 MAINTENANCE (enabled in TRONIC or PULSE TRONIC mode only)
- Leave the battery charger connected to the mains.
- Do not interrupt the charge process.
- Leave the charge clamps connected to the battery even after the charge
process has been completed.
The battery charger will automatically interrupt and reboot the charge phase
maintaining the battery voltage within the product default voltage range.
7. OPERATION DURING STARTING
WARNING: Before proceeding with starting follow the vehicle
manufacturer’s instructions carefully!
- Make sure the power line is protected by fuses or automatic circuit-
breakers with sizes as indicated on the rating plate by the (
)
symbol.
- To make starting easier, quickly charge for 10-15 minutes at the BOOST/
BOOST&GO position (see paragraph 6.3.1).
- In order to prevent overheating in the battery charger, ALWAYS carry
out the starting operation according to the duty cycle (work/pause) as
indicated on the appliance (e.g. START 3s ON 120s OFF-5 CYCLES). Do not
insist if the engine does not start: this could cause serious damage to the
battery or even to the electrical equipment in the vehicle. If the engine
does not start, wait a few minutes and then repeat the rapid charge
operation.
7.1 BATTERY CHARGER/BATTERY CONNECTION
- With the power cable disconnected from the mains, if necessary, turn the
deviator to 12V or 24V or suitably connect the red crocodile clip to the
specic battery charger terminal, according to the nominal voltage of the
battery of the vehicle to be started.
- Make sure the battery is connected properly to the respective (+ and -)
terminals, and that it is in good condition (not sulphated or dud). Never
ever start vehicles with the batteries disconnected from their respective
terminals; the presence of the battery is essential for the elimination of
possible overvoltage.
7.2 STARTING UP WITH START (FIG. E1)
- With the battery charger at OFF, plug in the power cable.
- Turn the switch, if present, to ON.
- Turn the switch to START and turn the ignition key to start up the engine.
7.3 STARTING UP WITH BOOST&GO (FIG. E2)
- Turn the switch to BOOST&GO.
- Power the battery charger by inserting the power cable into the mains
socket.
- Start up the vehicle by turning the ignition key.
7.4 END OF STARTING
- Disconnect the power to the battery charger by turning the switch (if
present) to OFF and remove the power cable from the mains.
- Disconnect the black crocodile clip from the negative battery terminal (-
symbol) and the red crocodile clip from the positive battery terminal (+
symbol).
- Store the battery charger in a dry place.
8. BATTERY CHARGER PROTECTION (FIG. F)
The battery charger protects itself from:
- Overcharge (too much current supplied to the battery).
- Short-circuit (loading clips placed in contact with each other).
- Polarity inversion on the battery clamps.
For appliances tted with fuses, if the fuses have to be replaced always use
the same kind of fuse with the same rated size.
WARNING: If the replacement fuse has a dierent size from that shown on
the rating plate it could cause damage to people or property. For the same
reason, never ever replace the fuse with a bridge in copper or other material.
The power supply cable should always be DISCONNECTED from the mains
supply while the fuse is being changed.
When replacing the ribbon fuse, if present, carefully fasten the nuts.
9. USEFUL ADVICE
- If the positive and negative terminals are incrusted with oxide, clean them
to ensure good contacts with the clamps.
- Never ever allow the two clamps to come into contact when the battery
charger is connected to the mains. In this case the fuse will blow.
- If the battery, to which this battery charger is to be connected,
is permanently installed in the vehicle, also consult the vehicle
manufacturer’s user’s and maintenance handbook under the “ELECTRICAL
SYSTEM” or “MAINTENANCE” section.
