Figure 3: Diagram of the charging process
Initial charging
The device charges using an initial charge current until the battery voltage rises to the initial charge voltage. The
voltage is then maintained for a specified period until the main charge starts. During the initial charging phase, the
"Initial/Bulk" indicator will flash.
Bulk charging
The device charges using the bulk charge current until the battery voltage rises to the bulk charge voltage. It then
maintains this voltage for a specified period before it starts the absorption charge. During the bulk charging phase,
the "Initial/Bulk" indicator will be steady on.
Absorption charging
In the absorption charging phase, the device charges at the absorption charging current until the absorption charg-
ing voltage is reached. Once this voltage has been achieved, the device monitors the change rate of the charging
current in accordance with the setting for the transition from absorption to trickle charging.
When the set transition limit from absorption to trickle charge is achieved, the device switches to trickle charging
mode. A connected generator is then automatically stopped in this process.
If regenerative charging is present, this is then carried out.
The "Absorption" indicator will be steady on during the absorption phase.
Trickle charging (FLOAT)
The device maintains the battery voltage at the trickle level and feeds up to the trickle current to maintain the trickle
voltage. The device remains in this charging phase, until the battery voltage drops below the level for the return to
initial charging.
If the device is still connected to an AC source after 24 hours of trickle charging, the charging unit changes to long-
term trickle voltage. The long-term trickle voltage allows the batteries to remain at a lower voltage level for an
unlimited time, reducing battery losses.
Regenerative charging (EQUALISE)
The device carries out Regenerative charging at regular intervals where the battery is kept at a higher voltage for a
period specified in the EQUALISE window. This ensures that all cells in the battery have the same charge volume.
The "Equalise" indicator will be steady on in regenerative charging and flashes when a regenerative charge is pres-
ent; this means that the charging unit implements a regenerative charge after the trickle phase is complete.
