End of normal charge: when the above-mentioned time has elapsed, the green L3 LED, indicating
“BATTERY OK”, lights up.
Then an equalizing charge, if enabled (CEQ jumper), takes place.
Pause: 60min-long charge interruption which separates the end of normal charge and the beginning of the
equalizing charge.
Equalizing charge:
After the normal charge a pause will take place (T.Pause = 60 min) after which Equalizing will be performed
(for a Teq time = 45h).
Equalizing is made up of a certain amount (Np=3) of pulse (Neq=5) packages, each of which consists of
charges (T.ON=12min) and pauses (T. OFF=48min).
The above mentioned pulse packages alternate with pauses (Ts = 15h).
These pulses are performed during the Active cycle (=45h), followed by a Stop cycle (=120h).
This equalizing system has no time limits and stops on battery disconnection.
The system is very useful during holidays and week-ends, since it makes it possible to keep battery charged
while preventing overcharging, overheating, and/or water consumption.
FLOATING CHARGE
At the end of a complete equalized charge cycle ( 45 hours ) if the battery remains connected (during holidays
for instance ) the equalization cycles are repeated every 120 hours (5 day )
This cycle of charge, that compensates the battery self–discharge , is repeated until the user remove the
battery.
Warning :
• Before disconnecting the battery, check whether the charging process has been completed. If the
charging process is still being performed and needs being interrupted, press the ON-OFF button.
• Never disconnect the battery connector before interrupting the charging process !
The charging process can be interrupted without disconnecting battery by pressing the ON-OFF button; in this
way charging times are stored and by pressing the ON button again, the charging process is resumed from the
point of interruption.
If battery is disconnected during a pause of the equalizing charge or after entering the OFF status by pressing
the relevant push-button, the battery charger will reset and it will begin a new charge on connecting the new
battery.
