Cycles)

Prior to the beginning of Cycle 3, the AC source was lost. The battery voltage decreased below
the level of the
Re-
Bulk
set point. Whenever this occurs, the Absorption time
r resets to its
maximum amount.

In Figure 7, Cycle 3 begins when the AC source is restored again. The charger begins a new cycle
by entering B
ulk stage. When it enters Absorption, the timer runs until it is interrupted by a lo
ss of
AC power.

Following Cycle 3, the voltage does not decrease below
Re-Bulk
. The Absorption timer retains the
remai
ning time from Cycl
e 3.

Cycle 4 begins when the AC source is restored again. The charger enters Bulk stage and proceeds
to Absorption
. This stage does not last for the full duration of the
Absorb Time
se
tting. The timer
use
s up the remaining time from Cycle 3. Absorption ends when the timer expi
res.
In this examp
le, the duration was also longer than the
Float Time
setting. Because the Float ti
mer
bega
n running near the beginning of Cycle 3 and also Cycle 4 (when the batteries exceeded
the
Float Voltag
e
setting), the
Float Time
has also expired. The charger does no
t enter Refloat or Float
and go
es Sile
nt.
Duri
ng the Silent period, AC is lost again. The battery voltage decreases until it reaches the
Re-Bulk
set point, prompting a new charge cycle. The Absorption timer resets to its
maximum amount.

When Cycle 5 begins, the charger proceeds through the Bulk stage and then the Absorption stage.
At the end of Cycle 5, the
Float Time
h
as expired, so the charge
r goes Silent.
