ABSORPTION phase:
Starts when the voltage has reached the maximum BOOST level. The current level starts falling.
These two phases combined last a maximum of TBOOST+TABS (depending on setting). If the current falls
below 20% of rated current, the FLOATING phase automatically kicks in. Duration and current intensity
depend on how charged the battery is.
FLOATING phase:
Starts after TBOOST or if output current has reached 20% of the charger's rated current. The voltage
switches to the FLOATING value and the rated current continues to drop.
REFRESH phase:
It is an automatic weekly cycle in order to optimize the battery life duration.
It will occur only after a complete recharge cycle (BOOST, ABSORPTION and FLOATING). The charger will
generate automatically a safe timed voltage step every 7 days even if REFRESH phase is off (see section
3.3.1.2)
Phase REBOOST:
Automatic phase consisting in coming back to a BOOST voltage if the DC utilizations require it (i.e., after a
complete recharge cycle BOOST, ABSORPTION and FLOATING if some DC constant consumptions are
detected the charger will restart a new complete charge cycle including a BOOST phase).
This REBOOST phase will be authorized after measuring certain battery voltage during a determined time.
3.6.2 BOOST and REFRESH in OFF position
With this setting, the charger produces a single-stage UI type charge curve. It generates a
constant voltage VFloat, supplying the current required by the battery(ies). Recharging time depends on the
state of the battery, being longer than when the BOOST is in the ON position (see section 3.3.1.2 and
3.3.2.7).
3.6.3 BOOST in ON and REFRESH in OFF position
With this setting, the charger delivers the same charge curve IUoU as in chapter 3.6.1 but
without the REFRESH step.
