At the end of Absorption Stage, it transitions to the programmed "EQUALIZE VOLT-
AGE" (see programmable range and defaults at Table 6.2)
.
It remains in this stage for the
computed time T2.
This stage is displayed as"E-Equalization Stage" in the 2
nd
line of
Charging Mode screens in Remote Control EVO-RC-PLUS (Please refer to Table 3.2
at Section 3.6.4.2 of Owner's Manual for EVO-RC-PLUS).
The equalization current “
I
2
” is normally 5% to 10% of the Ah capacity of the battery.
This current is indirectly computed from the programmed "BULK CURRENT" ("Io").
As
recommended under the Setting Mode for the Bulk Charge Current, the "BULK
CURRENT" (“
I
o”) is
expected to be set at 10% to 20% of the Ah capacity of the
battery.
Hence, the Equalization Current “I
2
” will be automatically computed at 50% of
the set "BULK CURRENT" (“
I
o”) which will effectively amount to 5% to 10% of the Ah
capacity of the battery. For example, the Equalization Current “
I
2
” for a 200 Ah capacity
battery will be 10 A - 20A. The "BULK CURRENT" (“
I
o”) for a 200 Ah capacity at 10% -
20% will be set at 20 A - 40A. The firmware will compute the Equalization Current “
I
2
” at
50% of 20 A (i.e. 10A) or at 50% of 40A (i.e. 20A).
At the end of Adaptive Equalization Stage, the charger transitions to the programmed
"FLOAT VOLTAGE" (see programmable range and defaults at Table 6.2)
. This stage is dis-
played as"O-Float Stage" in the 2
nd
line of the Charging Mode screens in Remote
Control EVO-RC-PLUS (Please refer to Table 3.2 at Section 3.6.4 of Owner's Manual
for EVO-RC-PLUS).
Automatic Resetting of Charging Cycle
The charging cycle will be reset to the Bulk Stage of 3 Stage Charging Profile as follows:
If the AC is reconnected or the battery voltage drops below 12 VDC / 24 VDC (Default).
Programmable range for this voltage is 10 to 13V for 12V battery and 20 to 26V for 24V battery.
This parameter is called "RESET TO BULK". Please see Table 6.2 and Section 4.2.2.15 of the EVO-
RC-PLUS manual.
If the charger remains in the Float Mode for 10 days.
5.10 SWITCHING ON AND SWITCHING OFF OF EQUALIZATION
CHARGING PROFILE (4 STAGE CHARGING)
The default charging profile is 3 stage Adaptive Profile (See Table 5.2). Equalization Profile is
required to be selected manually as follows:
Using ON/OFF Push Button (11, Fig 2.1) on the Front Panel (only if the Remote
Control EVO-RC-PLUS is not available):
When the unit is in Charging Mode (qualified
Grid / Generator Input is available), the Blue LED “ON” (12, Fig 2.1) will be flashing once
per second. Press the ON/OFF Button for 1 second. The ongoing Charge Profile will be
terminated and Adaptive Equalization will be initiated. The Blue LED “ON” (12, Fig 2.1) will
start flashing 2 times per sec to show that Equalize "CHARGE MODE" is active. The unit will
complete Equalization and terminate in the last stage of the charging profile that was active
at the time the Equalize Profile was activated using the front panel On/Off Push Button (11,
Fig 2.1). Henceforth, charging will continue in the initial charging profile that was active
before equalization was initiated using the front panel On/Off Push Button (11, Fig 2.1). At
the same time, the Charging Profile Setting will again be reset to the original and the Blue
LED “ON” (12, Fig 2.1) will return to 1 flash per second.
To terminate Equalization Mode
prematurely before its completion, press the ON/OFF Push Button for 1 second.
