Step 3
: Input parameters according to your needs
(2) BULK CC (Constant current) charging voltage setting: to set the voltage where
BULK stage CC (constant current) mode turn to Absorption stage CV (Constant
Voltage) mode.
■ Available settings: (12V charger: 14 ~ 14.9V); (24V charger: 28 ~ 29.8V)
(3) Float voltage: to set the voltage where after Absorption (CV mode) turns to Float
stage.
■ Available settings: (12V charger: 13 ~ 13.9V); (24V charger: 26 ~ 27.8V)
(4) Return to BULK voltage: to set the voltage where Float turns to Bulk stage.
■ Available settings: (12V charger: 12 ~ 12.9V); (24V charger: 24 ~ 25.8V)
(5) Maximum output charging current: Maximum nominal output charging current.
■ The Maximum output charging current is a fixed value.
(6) Transit amps: to set the current threshold where Absorption 1 turns to Absorption 2.
It always shows as percentage of Nominal current.
■ Default setting: 6.25%
■ Available settings: 6.25%/12.5%/25%
(7) Bulk2 Timer: to set the time for Bulk 2 stage.
■ Default setting: 8 Hours
■ Available settings: 6~10 Hours
(8) Abs1 Timer: to set the time for Absorption 1 stage.
■ Default setting: 8 Hours
■ Available settings: 1~10 Hours
(9) Abs2 Timer: to set the time for Absorption 2 stage.
■ Default setting: 16 Hours
■ Available settings: 1~18 Hours
* Note1: Total 28 Hours max. for Absorption stage(Absorption1 + Absorption2).
* Note2: Battery charger will enter the float stage base on your Absorption time setting.
Warning! Absorption time below default setting, this may cause Battery NOT fully charged.
(10) Float Timer: to set the time for Float stage.
■ Default setting: 336 Hours
■ Available settings: 168~504 Hours
(11) Return amps current: Absorption 2 stage turn to Float current condition.
(12) “SEARCH” button: to search the device once the CX charger is connected.
(13) “PROG.” button: to write the parameters into CX charger.
(14) “READ” button: to read the current parameters from CX charger.
