5.7.3 Float Stage
Float Stage is a maintenance stage in which the output voltage is reduced to a lower level, typically
about 13.5 volts, (27 volts for 24V models) to maintain the battery’s charge without losing electrolyte
through gassing and also prevent corrosion of Positive plate by maintaining proper Positive Plate
Polarization Voltage. Programmable range of values of "FLOAT VOLTAGE" are shown in Table 6.2.
Default value is 13.5V for EVO-1212F / EVO-1212F-HW and 27.0V for EVO-1224F / EVO-1224F-HW.
For programming refer to Section 4.4.2.3 of EVO-RC-PLUS Manual.
This stage is displayed as "Float" "X-Float Stage" in the 2
nd
line of the in the Charging
Mode screens in the Remote Control EVO-RC-PLUS. Character "x" denotes code for one
of 6 Charging Proles that is active. (For details, please see Table 3.2 at Section 3.6.4.2
of Owner's Manual for EVO-RC-PLUS).
5.7.4 Automatic Resetting of Charging Cycle in 3 Stage Charging Prole
The charging cycle will be reset to the Bulk Stage as follows:
-
If the AC input from the Grid / Generator is disconnected and is reconnected or the bat
-
tery 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 "RE-
SET TO BULK". For programming information for this parameter, refer to Section 4.4.2.15
of EVO-RC-PLUS manual).
- If the charger remains in the Float Mode for 10 days.
5.8 4 STAGE ADAPTIVE CHARGING PROFILE - EQUALIZE
!
CAUTION!
4 stage Adaptive Charging Prole - Equalize should be used only on vented,
ooded (non-sealed or “wet”) batteries and not on sealed AGM / Gel Cell Lithium
batteries and only as often as recommended by the battery manufacturer.
!
ATTENTION!
Étape 4 - Prol de charge adaptative égaliser ne doit être utilisé que sur l'évacuation, inondé
(non-étanches ou "humide") et non sur les batteries AGM scellées / Gel cellules au lithium batteries
et qu'aussi souvent que recommandé par le fabricant de la batterie.
4 Stage battery Charging Cycle is used in Adaptive Equalization Charging Prole (See Table
5.2). Equalization Prole is activated using optional Remote Control EVO-RC-PLUS [Refer to
parameter "EQUALIZE-4STAGES" at Section 4.4.2.12 of EVO-RC-PLUS Owner's Manual. The
"EQUALIZE-4STAGES" option is required to be set at 1=Equalize (4-stage)] If Remote Control
EVO-RC-PLUS is not available, Equalize Cycle may be activated by presenting the On/Off Push
Button on the front panel (11, Fig 2.1) for 1 sec. The cycle can be stopped prematurely by
pressing the Push Button for 1 sec. See Section 5.10 for more dertails.
Equalization of the batteries is carried out periodically - normally once per month for
battery under heavy duty service and every two to four months for battery under light duty
service. As equalization is a deliberate overcharge of the battery for a specied time period,
equalizing your ooded / wet cell batteries will reduce sulfation, stir up the electrolyte to
remove stratication, equalize voltages of individual cells and thus, help reach and maintain
the peak capacity of the battery.
