STARTING
Connect the charger to the net (check the charger lable) and to the
battery (the charger switches on after battery connection only): a
few second later the charge begins automatically. The micropro-
cessor on the electronic card resets the charger and shows the set
charge cycle (see PAN.1). To change the cycle, open the charger and
move the jumper on the electronic card.
“IU” CHARGE CYCLE
The charge begins in “I-phase” (constant current) to let battery volt-
age increase (see PAN.2a). When the battery voltage reaches Vu
(see charger lable) the electronic card activates “U-phase”. In case
the battery voltage doesn’t reach Vu by 10 hours, the chargers will
STOP. During “U-phase” Vu (battery voltage) keeps constant, while
the output current of the chargers decreases down to small values.
“U-phase” lasts 5 hours, after that the chargers STOPs (battery to-
tally recharged)
“IUoU” CHARGE CYCLE
The charge begins in “I-phase” (constant current) to let battery volt-
age increase (see PAN.2b). When the battery voltage reaches Vu
(see charger lable) the electronic card activates “U-phase”. During
“U-phase” Vu (battery voltage) keeps constant while the output cur-
rent of the charger decreases up to 1/3 of the nominal value. At that
time begins “oU-phase”: constant value of battery voltage (Vou -
lower level than Vu) and decreasing output current. In IUoU charge
cycle there are no timers. The battery is substantally recharged be-
fore “oU-phase” begins, however in this case it’s necessary to push
STOP before disconnecting the battery from the charger
“IUIa” CHARGE CYCLE
The charge begins in “I-phase” (contasnt current) to let battery volt-
age increase (see PAN.2c). When the battery voltage reaches Vu
(see charger lable) the electronic card activates “U-phase”. In case
the battery voltage doesn’t reach Vu by 10 hours, the chargers will
STOP. During “U-phase” Vu (battery voltage) keeps constant, while
the output current of the chargers decreases down to 3-4% of the
nominal value (“U-phase” lasts maximum 5 hours). At that time the
card activates “Ia-phase”: output current keeps constant at 3-4% of
the nominal value while the battery voltage increases. “Ia-phase”
lasts 4 hours
SPECIAL FUNCTIONS
There are electronic protections against battery overvoltage, over-
current and inside overtemperature: in these case the micropro-
cessor stops the charge (see drawing n°3 and n°5). If it happenes
it’s neccery to disconnect the battery for 1 minutes before starting
again, anyway in these cases its better to call a technician. In case
there are no LED’s switched on, have a look on the following points:
battery connection, net connection, fuses (see drawing n°4). In case
it’s necessary to stop the charge before the right time, push STOP
for 4 seconds before disconneting the battery
