WARNING: When handling the cables, make sure that the unit has been set to the "OFF" position indicated by an illuminated lED on the
front panel.
4.5
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.
4.6
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 generally the one that is not connected to the vehicle chassis.
4.7
Connect the red charge clamp to the positive terminal of the battery (+symbol).
4.8
Connect the black charge clamp to the vehicle chassis, far away from the battery and from the fuel system. NOTE: If the battery is not
installed in the vehicle, connect the black clamp directly to the negative terminal on the battery (-symbol).
4.9
Power the battery charger by inserting the power supply plug into the mains socket outlet. Position the switch on the back to the (I) position.
4.10
Set the operating mode to 'TEST'.
4.11
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 in "TEST" mode.
4.12
Set an appropriate current value using the potentiometer on the front panel.
5. OPERATION
5.1
CHARGING
5.1.1
Set the operating mode to "CHARGE" . Switch the battery charger to "ON" and confirm that the 'ON' led is illuminated.
5.1.2
monitor the battery voltage and charge current parameters using the "I/V/TImE" key next to the display. (See fig.1-6).
5.1.3
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.
5.2
AUTOMATIC CHARGING
Set the operating mode to "TRONIC". Switch the battery charger to "ON" and confirm that the 'ON' led is illuminated. In this mode the
battery charger constantly monitors the voltage over the battery terminals, automatically supplying or cutting off the charge current to
the battery as necessary. When it is cut off the display will show the message "END". Also in this case it is possible to monitor the
battery voltage and charge current on the display using the 'I/V/TImE"key. The charge current can also be set.
5.2.1
Simultaneous charging of more than one battery. 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.

PARALLEL
5.3
END OF CHARGING
It is possible to end charging by pressing the "OFF" key or 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).
