CAution!
For effective equalization to take place, it is desirable that the batteries undergo a
longer bulk Stage applicable to the deeply discharged condition of the battery.
Please ensure that before the batteries are equalized, they should be deeply
–
discharged to 20% of its capacity. the Standing Voltage (terminal Voltage after
disconnecting charging source[s] and load[s] for at least 3 hours) at 20% capacity
will be:
o
12V battery: Around 11.7V
o
24V battery: Around 23.4V
Do not equalize partially or fully charged batteries
–
!
Attention!
Pour une égalisation efficace, il faut que les batteries subissent à une étape majeure plus long en fonction de
la condition déchargée de la batterie.
Veuillez assurer que les batteries sont profondément déchargées (à 20% de sa capacité), avant de les
–
égaliser. La tension constante (la tension de la borne après avoir déconnecter toutes sources de charge
pour un minimum de 3 heures) quand elles sont déchargées à à 20% de sa capacité, serait:
o
Une batterie de 12V: Environ 11,7V
o
Une batterie de 24V: Environ 23,4V
N'égalisez pas des batteries qui sont partiellement ou complètement chargées

During the bulk Stage, the charger will charge at the programmed "bULK CUrrENT"
–
("Io") (see programmable range at Table 6.2. Default value is 40A). "bULK CUrrENT"
("Io") is normally limited to 10%-20% of the Ah capacity of the battery (20Hr rate).
Higher current may be used if permitted by the battery manufacturer in Equalization
Mode. the bulk Stage is displayed as "e-CC" in the Charging Mode screens of the
optional remote Control eVo-rC (Please refer to Section 3.6.1 of owner's Manual
for eVo-rC at Appendix A).
A Software Timer is used to measure the time taken from the time the unit transfers to the
–
Utility / Generator Mode / enters bulk Stage until the battery charger reaches 0.3V below
the Absorption Voltage, then registered this time as time To. The following times are com-
puted based on the time To:
Absorption Time T1' = To x 0.5
–
Equalization Time T2 is then computed based on the following logic:
–
T2 = T1' + 1 hr = 0.5 To + 1 hr ; if T1' < 2 hrs
T2 = T1' + 2 hrs = 0.5 To + 2 hrs ; if 2 < T1' < 4 hrs
T2 = T1' + 4 hrs = 0.5 To + 4 hrs ; if T1' > 4 hrs
When the battery reaches the programmed Absorption Voltage (see programmable
–
range and defaults at Table 6.2), it transitions to the Absorption Stage and remains in this
stage for the computed time T1'. this stage is displayed as "e-CVA" in the Charging
Mode screens in remote Control eVo-rC (Please refer to Section 3.6.1 of owner's
Manual for eVo-rC at Appendix A).
