Details of the 5 programmable charging profiles are given in Table 5.2.
NOTE:
4-Stage Equalize Charging Profile is also available and can be activated anytime dur-
ing charging taking place under one of the 5 Charging Profile options given above.
Procedure to activate Equalize Charging Profile is described under programmable
Parameter "EQUALIZE-4STAGES" at Section 4.4.2.12.
!
CAUTION!
The Battery Management System (BMS) that comes with the type of Lithium Battery
being used will need to have control over charging and discharging of the battery.
For this, Pins 4 and 5 of the temperature Sensor Jack (6, Fig 4.1) may be used to
feed potential free contact closing signal from the BMS to “Stop Charging” or “Stop
Inverting” Refer to Section 5.12 of the EVO 1212F / 1212F-HW / 1224 / 1224-HW

Condition
0=3 Stage Adaptive
(Default)
1.
Bulk Stage:
Charge at constant current equal to
programmable parameter “BULK CURRENT”
• Transition to Absorption Stage when voltage rises to
programmable parameter “ABSORP VOLTAGE”.
2. Absorption Stage: Charge at constant voltage at
programmable parameter “ABSORP VOLTAGE”.
• Adaptive Time Algorithm: Time in Absorption
Stage is computed automatically based on time
in Bulk Stage. Transition to Float Stage thereafter.
3. Float Stage: Charge at constant voltage equal to
programmable parameter “ “FLOAT VOLTAGE”
• Reset to Bulk Stage under the following conditions:
ú After 10 days in Float Stage, or
ú Voltage drops to programmable voltage
parameter “RESET TO BULK”
• Lead Acid: Flooded
and sealed – AGM/
Gel Cell
• ENSURE that
there are no other
DC load(s) on the
batteries. Load(s)
on the battery may
drain full or part of
the charging current
and will upset the
“Adaptive Algo-
rithm” for Absorp-
tion Stage time
1 = 3 Stage Type 1 1. Bulk Stage: Charge at constant current equal to
programmable parameter “BULK CURRENT”
• Transition to Absorption Stage when voltage
rises to programmable parameter “ABSORP
VOLTAGE”.
2.
Absorption Stage:
Charge at constant voltage at
programmable parameter “ABSORP VOLTAGE”.
• Time in Absorption Stage is programmable
through parameter “ABSORP TIME”. Transition
to Float Stage thereafter
3.
Float Stage:
Charge at constant voltage equal to
programmable parameter “ “FLOAT VOLTAGE”
• Reset to Bulk Stage under the following conditions:
ú After 10 days in Float Stage, or
ú Voltage drops to programmable voltage
parameter “RESET TO BULK”
• Lead Acid: Flooded
and sealed – AGM/
Gel Cell
• Lithium
