5.5
MULTIPLE CHARGING
WARNING! DO NOT simultaneously charge different types of battery or batteries with different
capacities or levels of discharge.
5.5.1
Simultaneous multiple charging should be carried out in series, since this enables monitoring of
the current circulating in each battery. Refer to Fig.12.
NOTE:
If two batteries with rated voltages of 12V are connected in series, set the battery voltage
selection key on the front panel to 24V and move the positive cable to the 24V terminal, see Fg.3-3.
5.6
COMPLETION OF CHARGING
5.6.1
On the battery charger front panel, set the operating mode selection key to TEST. See 7 in Fig.4.
5.6.2
Set the battery charger mains switch to OFF.
5.6.3
Disconnect the BLACK clamp from the chassis, or from the battery negative terminal (- symbol).
5.6.4
Disconnect the RED clamp from the battery positive terminal (+ symbol).
5.6.5
Store the battery charger in a dry location.
5.7
STARTING
NOTE:
Never attempt to start a vehicle with the battery disconnected. The presence of the battery is
essential for the elimination of possible overvoltage that may be generated due to energy
accumulating in the connection cables at the starting stage.
5.7.1
On the battery charger front panel, set the CHARGER/STARTER selection switch to STARTER.
See 2 in Fig.3. The display will show the message 'Str', see Fig.13.
WARNING! Ensure that the power supply line is fused or has an automatic switch
corresponding to that shown in the data plate in the top of the control panel.
5.7.2
Set the mode switch to CHARGE (see 2 in Fig.3) and rapidly charge the battery for between 5
to
10 minutes, to ease starting. Switch back to START mode after rapid charging.
NOTE: The starting operation must strictly follow the WORK/PAUSE cycle (i.e. START, 3
seconds ON,120 seconds OFF, to a maximum of 5 cycles).
5.7.3
If the engine does not start, discontinue the operation, or the battery and/or the vehicle electrical
system will be damaged.
6. ALARMS AND SAFEGUARDS
6.1
The overheating safeguard is displayed as shown in Fig.14. It shows that the battery charger is
overheated. It will stay displayed, without supplying current, until it returns to normal temperature.
Reset is automatic.
6.2
The battery charger has three protection levels, shown in Figs.15, 16 and 17. L1 gives maximum
protection with connection and/or setting error detection and charge current limitation. L2 gives
intermediate protection with connection and/or setting error detection. L3 has ALL safeguards
disabled.
NOTE: The user has the option of totally or partially removing the safeguards (3 PROTECTION LEVELS)
by the following procedure:
A) In test mode press the I/V key for about 5 seconds until the current is no longer displayed and
either L1, L2 or L3 is displayed.
B) Turn the potentiometer to select the desired protection level
NOTE: The protection level shown initially depends on the actual position of the potentiometer.
Save the choice by pressing the I/V key.
NOTE: To enable the charging of very flat, or sulphated, batteries it may be necessary to disable all
safeguards. Each time the battery charger is switched on, it automatically returns to the maximum
protection level (L1)
