The equalization current "I
–
This current is indirectly computed from the programmed bulk Charge Current. As
recommended under the Setting mode for the bulk charge current, the bulk
charge current "Io" is expected to be set at 10% to 20% of the Ah capacity of the
battery. hence, the Equalization current "I
the set bulk Charge Current "Io" which will effectively amount to 5% to 10% of the Ah
capacity of the battery. for example, the Equalization Current "I
battery will be 10 A - 20A. The bulk Charge current "Io" for a 200 Ah capacity at 10% -
20% will be set at 20 A - 40A. The firmware will compute the Equalization Current "I
50% of 20 A (i.e. 10A) or at 50% of 40A (i.e. 20A).
At the end of Equalization Stage, the charger transitions to the programmed float Voltage
–
(see programmable range and defaults at Table 5.1). this stage is displayed as"float"
in the charging mode screens in remote control evo-rc (Please refer to Section
3.6.1 at Appendix A).
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 "fLOATING EXIT". Please see Table 6.2 and Section 4.4 of Appendix A)
- If the charger remains in the float Mode for 10 days.
5.9 Switching on AnD Switching off of eQuAliZAtion moDe
(4 StAge chArging)
The unit comes preset for charging in Normal Charging Profile (3 Stage Charging Profile).
Equalization Profile (4 Stage Charging Profile) is required to be selected manually as follows:
using on/off Push button on the front Panel: When the unit is in Charging Mode (qualified
Grid / Generator Input is available), the Green LED "Status" will be flashing once per second.
Press the ON/Off button for 1 second. The ongoing Normal Charging Mode will be terminated
and Equalization Mode will be initiated. The Green "Status" LED will start flashing 2 times per sec
to show that Equalization Mode is active. The unit will complete Equalization Cycle and terminate
in float Stage. At the same time, the Charge Mode Setting will again reset to Normal Mode
and the Green LED "Status" will return to 1 flash per second. To terminate Equalization Mode
prematurely before its completion, press the ON/Off Push button for 1 second.
If the unit was in Inverting Mode (Green LED "Status" steady) and the Mode is set to
Equalization as above by pressing the ON/Off Push button for 1 second, the unit will
undergo Equalization Mode whenever qualified AC input is available from Grid / Generator
and the unit enters Charging Mode. To terminate Equalization Mode prematurely before its
completion, press the ON/Off Push button for 1 second.
note: Procedure described above is to be used when the optional remote
Control EVO-rC has NOT been plugged into the rJ-45 remote Control
Jack. Please note if the remote Control has been plugged into the rJ-
45 Jack, the above procedure cannot be activated and the ON/Off of
Equalization Mode will be controlled by the remote Control EVO-rC.
using optional remote control evo-rc: Please refer to the attached manual for
EVO-rC at Appendix A.
