Simultaneous charging of more than one battery (FIG.
D)
Take very great care when carrying out this type of
operation: WARNING; do not carry out simultaneous
charging of batteries of different capacities or types, or if
their charge conditions differ.
Batteries that are to be charged simultaneously can be
connected in "series" or in "parallel". Of the two systems, we
recommend connecting in series because in this way it is
possible to monitor the current circulating in each battery,
which will be the same as that shown by the ammeter.
NOTE: If two batteries with rated voltages of 12V are
connected in series, the battery charger MUST be set to the
24V position.
END OF CHARGING
-It is possible to END charging by pressing the "OFF" key or
else the battery charger can be left to switch itself
automatically to "OFF" when the time runs out.
-Disconnect the power supply to the battery charger by
removing the power supply cable from the mains socket.
-Disconnect the black charge clamp from the vehicle chassis
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 the battery cells using the appropriate caps (if
present).
STARTING
Press the corresponding key to pass to "START" mode.
For starting set up the battery charger in the start position at
the correct voltage.
Within this mode the status of the charger is one of three
types:
- Pause status, countdown lasting "40 seconds"
- Waiting for user to start status, "GO";
- Starting status "4 seconds".
NOTE: For further details about the indicator see FIG. B.
Before turning the starter key, it is essential to make a
rapid charge of 5-10 minutes, which will greatly facilitate
starting.
Rapid charge should be carried out only and exclusively
with the battery charger in charge mode and not in start
mode.
If no alarms of any type have triggered, you may
proceed as follows.
Before starting the vehicle, make sure the battery
terminal is properly connected to the respective clamps
("+" and "-") and that the battery is in good condition
(not sulphated or failed).
Never ever start vehicles with the battery terminals
disconnected from their respective clamps; the
presence of the battery is essential for eliminating any
possible overvoltage that could be generated by the
energy accumulating in the connecting cables during
the starting phase.
Failure to observe these instructions may damage the
vehicle electronics.
_________________________________________________________________________________
WARNING:
- Before proceeding further read the vehicle manufacturer's
instructions carefully.
- Ensure that the power supply line is protected by fuses or
automatic switches with a capacity corresponding to that
shown on the rating plate with the symbol (
- To prevent overheating in the battery charger, carry out
the starting operation keeping STRICTLY to the
work/pause cycles indicated on the appliance. Do not
insist further if the vehicle engine does not start: this could
seriously damage the battery or even the electrical and
electronic equipment in the vehicle.
- It is absolutely necessary to allow the starting phase
of the battery charger, indicated by "RUN" on the
display, to conclude even if the vehicle engine does
not start to turn.
_________________________________________________________________________________
WARNING:
This battery charger/starter is a microprocessor-controlled
electronic appliance that is able to protect the vehicle
electronics from overvoltage that may be generated when
charging particularly flat or sulphated batteries. In this case
the protective capacity is demonstrated by blocking the
charge function every time the "ON" key is pressed: just a
fraction of a second is needed to evaluate the condition of
the battery and automatically interrupt charging on detection
of overvoltage risks that are a danger to vehicle appliances
which are connected electrically to the battery terminals.
WARNING: select the charge voltage to match the rated
voltage of the battery to be charged.
CHARGING VERY FLAT OR SULPHATED BATTERIES
WARNING: under these charge conditions the vehicle
electronics is not protected, therefore it is absolutely
necessary to disconnect the battery from the vehicle.
To be able to charge such batteries it is necessary to
override the intrinsic property of the battery charger, which
provides protection against overvoltage that could destroy
the vehicle electronics.
The user has the possibility of totally or partially removing
these safeguards (3 protection LEVELS) by adopting the
following procedure:
- In "TEST" mode press the "I / V / TIME" key for about 4
seconds until the current display disappears and either
"L1", "L2" or "L3" is displayed.
- Press the "HOURS" key to select the desired protection
level:
"L1" = maximum protection with detection of connection
and/or setting error enabled and limitation of actual
charge enabled;
"L2" = intermediate protection with only detection of
connection and/or setting error enabled, overvoltage and
ripple protection enabled;
"L3" = all safeguards disabled.
- Save the choice of protection level by pressing the "I / V /
TIME" key for about 4 seconds.
Every time the battery charger is switched on it
automatically returns to the maximum protection level
"L1".
STARTING VERY FLAT OR SULPHATED BATTERIES
(NOT RECOMMENDED)
To be able to start potentially sulphated or very flat
batteries it may be necessary to start the vehicle
without the support of the electronic safeguards (NOT
RECOMMENDED). In any case, in order to prevent
damage to on-board electronics (a possibility with
sulphated or very flat batteries) it is NECESSARY to
allow the starter to conclude the 4-second start cycle
even if the vehicle engine does not start to turn.
7. SAFEGUARDS (FIG. E)
The battery charger is fitted with safeguards that trigger in
the case of:
- over-charging (excess current output to the battery);
- overvoltage (battery or instant charging voltage too high);
- short circuit (charge clamps in contact with one another);
- reverse polarity on battery terminals;
If it is necessary to replace the fuses in appliances fitted with
).
them, use compatible replacements with the same rated
current value.

current values from those indicated on the rating plate
