DISCHARGE-CHARGE IN MANUAL MODE REGE
NERATION MANUAL (REM)
Three discharge-/charge cycles are run through in this opera-
ting mode. This means that both the charge and discharge
current must be programmed manually in the "setting" display;
the discharge end voltage is automatically determined. The
process begins with discharging the battery. This is followed
by recharging. This cycle is run through three times. At the
end, a charged battery is available.
This procedure is applied to improve the condition of NiCd or
NiMH batteries. There is more capacity available subsequent
to this.
There are no improvements from this procedure with lithium-
ion batteries (LI), lithium polymer batteries (LP) and lead batte-
ries (Pb). The software therefore does not supply for these
types.

REGENERATION PROGRAM (D/C)
A regeneration program is made available for all battery types
with this program.
In this operating mode, the battery is discharged first.
Subsequently, the battery is recharged depending on the pre-
set battery capacity with a charge current C/5.
The discharge current, the capacity and the cell count must be
set manually.
Important:
The following settings are to be carried out depending on
the selected battery type to achieve correct disconnection
during a charging process:
Lead battery:
Additional entry of the charge current.
Explanation: The disconnection criterion for lead batteries is
coupled to the charge current on the Profi Homecharger. The
charge process is stopped if the charge current reaches 10%
of the set value.
However, this would lead to an unnecessarily long 2nd charge
phase as lead batteries have a very high leakage current. We
recommend you set the charge current to the maximal value
(5A).
Lithium-ion / lithium polymer batteries:
Additional entry of the charge current.
Explanation: The disconnection criterion for lithium batteries
is coupled to the charge current on the Profi Homecharger.
The charge process is stopped if the charge current reaches
10% of the set value.
We recommend you set the charge current to 1C.
The duration of the 2nd charge phase can be determined wit-
hin certain limits by an experienced user consciously setting a
higher or lower charge current than 1C with lithium cells.
Examples:
- Charge current smaller = about 0.5 C -> The 2nd charge
phase lasts longer because is it disconnected with a smal-
ler residual current.
- Charge current larger = about 2 C -> The 2nd charge
phase is shorter because is it disconnected with a higher
residual current. The battery is therefore not completely
charged.

ERROR MESSAGES
The Profi Homecharger is equipped with safety features to
guarantee safe charging or discharging processes. As soon as
an error occurs, a corresponding message appears in the dis-
play and a piezo buzzer sounds a shrill warning tone.
9.1 REVERSE BATTERY / SHORT-CIRCUIT OF AN OUTPUT
All Outputs of the Profi Homecharger are protected against
reverse polarity of connected batteries. If a battery is connec-
ted to an Output with the wrong polarity, then a loud constant
tone will sound as a warning, the Output LED lights up red and
the error is shown in the display.
The same applies if a short circuit occurs on one of the Out-
puts.
The following display shows the error display.
For reasons of safety, a charge or discharge current does not
flow in this condition.
As soon as the battery is unplugged or the short circuit has
been removed, the LED will go out, the warning tone will stop
and the previous display will appear again.
9.2
INTERRUPTION
If the charge cable or the battery have a loose contact and it
leads to an interruption in the charge or discharge current,
there will appear a corresponding error message in the display
and the buzzer will sound.
The corresponding Output is marked by a red, steady Output
LED.
The same warning signs are displayed optically and acousti-
cally if the battery is removed from the charge device without it
being fully charged.
One of the three keys must be pressed to delete these warning
signals.
NOTE:
The charge process will be restarted after re-establishing the
power supply if there is an interruption of the charge process
at the input point of the charge device, for example as a result
of power failure, or unintentionally pulling the mains supply
plug etc.
This means that the Profi Homecharger starts with the first
charge Output at which a battery is connected. All occupied
Outputs are executed one after each other.
Since the batteries at the already executed Outputs are full,
the charger will quickly get back to the Output which was
active at the time of power interruption and resume the charge
process.
Order No.
