The three LED's indicate the condition of the battery by
reading its voltage. The top LED indicates a charged
battery, with a battery voltage reading greater than or
equal to the voltage setting. The middle LED indicates that
the battery is able to receive more current and, lastly, the
bottom LED indicates that the battery is flat.
NOTE: for further details about the indicator see FIG. B
6- (DISPLAY) Current/Voltage/Time indicator :
This key can be used to select 3 different indicators:
- "I", displays the output current in Amps, in both
"CHARGE", and "TRONIC" modes.
- "V", in this position the display shows the output voltage
over the battery terminals in Volts.
- "TIME", in this position the display indicates the length
of time that has elapsed during "CHARGE" mode, in
minutes.
- The display also shows a set of letters representing the
current condition /mode (FIG. B).
- In "START-PAUSE" mode the display shows the time
remaining during the forced pause, in seconds.
7- Selecting Charging Time:
This key is used to select the charging time for the
"CHARGE" function; the following times are available:
2/4/6/10 hours.
In "CHARGE" mode, if the preset time passes before the
end-of-charge voltage is reached, the battery charger will
automatically charge for 2 more hours and then switch off.
8- Potentiometer:
This potentiometer is used to set the charge current in
both "CHARGE" and "TRONIC" modes.
9- (OFF) Switching off:
This key switches the current to the battery/ies ON or OFF.
WARNING: the battery charger is still powered even
when the OFF LED is lit.
5. INSTALLATION
SETTING UP (FIG. C)
- Unpack the battery charger and assemble the separate
parts included in the package.
POSITIONING THE BATTERY CHARGER
- Position the battery charger for operation, making sure
that it is stable and that there is sufficient ventilation with
no obstructions to air passage through the vents provided
for this purpose.
- Install the battery charger on a horizontal surface with a
solid base.
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
W
by the label ( ), while the other two wires should be
connected to the mains.
6. 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):
1.28 = charged battery
1.21 = half-charged battery
1.14 = flat battery
_________________________________________________________________________________
WARNING: When handling the cables, make sure
that the "OFF" LED on the front panel is lit up.
_________________________________________________________________________________
- Check the battery voltage and make sure that the settings
on the battery charger panel are compatible with the
specifications for the battery being charged.
- Check the polarity of the battery terminals: positive for the
+ symbol and negative for the - symbol.
NOTE: if it is impossible to distinguish between the
symbols, bear in mind that the positive terminal is the one
that is not connected to the vehicle chassis.
- Connect the red charge clamp to the positive terminal of
the battery (+ symbol).
- Connect the black charge clamp to the vehicle chassis, far
away from the battery and from the fuel pipe.
NOTE: if the battery is not installed in the vehicle, connect
the black clamp directly to the negative terminal on the
battery (- symbol).
- Power the battery charger by inserting the power supply
cable into the mains outlet.
Position the switch on the back to the ( I ) position.
- Check the battery voltage and make sure that the settings
on the battery charger panel are compatible with the
specifications for the battery being charged. These
checks should be carried out with the corresponding key
in "TEST" mode.
- Set an appropriate current value using the potentiometer
on the front panel.
CHARGING
Press the corresponding key to pass to "CHARGE" mode.
Position the battery charger to "ON" by pressing the
corresponding key on the front panel.
Monitor the battery voltage and charge current parameters
on the display using the "V / I/ TIME" key (FIG.A-6).
The ammeter will show the charge current (in amps) for the
battery: at the end of this phase you will see that the value
shown on the ammeter will decrease slowly to very low
values, according to the capacity of the battery and its
condition.
AUTOMATIC CHARGING
Press the corresponding key to pass to "TRONIC" mode.
Position the battery charger to "ON" by pressing the
corresponding key on the front panel.
During this phase the battery charger constantly monitors
the voltage over the battery terminals, automatically
supplying or cutting off the charge current to the battery as
necessary.
Also in this case it is possible to monitor the battery voltage
and charge current on the display using the "V / I / TIME" key.
The charge current can be set as illustrated. When it is cut off
the display will show the message "END".
