Hartig+Helling BL 506 Bedienungsanleitung Seite 5

It is suitable to charge AAA-
sized and AA-sized NiCd and
NiMH accumulators. The
accumulators can be charged in
pairs (2 or 4).
In addition to the discharging,
high-rate charging and trickle
charging functions, the charger
is also provided with a voltage
control monitoring function
(∆U) to prevent the accumu-
lators from over-charging.
BL 506 consists of the charger,
a mains adapter and the car
adapter for connection to the
cigarette lighter in your car.
During the initial charging
operations the charger may
smell due to heat development
when charging. This is not a
fault of the device but a quite
normal phenomenon which
disappears after a few charging
operations.
Please note to simultaneously
charge accumulators of the
same size and same capacity
only. Simultaneous charging of
accumulators of different
capacities would result in an
over-charge of the accumulators
with the lower capacity.

Discharging and charging
1. Connect BL 506 with the mains
adapter and then with the mains
(230 V AC).
2. The yellow LED at the right will
light up for a short period of
time.
3. Select two or four accumulators
for charging. If you want to
charge two accumulators, set
the switch to "2", if you want to
charge four accumulators, put
the switch in the "4" position.
4. Now insert your accumulators in
the compartment provided for
this purpose (CH1–CH 4).
The red LED will light up.
5. If the accumulators are to be
discharged prior to charging,
press the discharging button to
start discharging. Discharging is
displayed by the yellow LED
which will light up. On
completion of discharging the
charger will change over to
high-rate charging automatically.
Charging is displayed by the red
LED which lights up.
6. If you do not want to discharge
the accumulators prior to
charging, insert them into the
compartments provided for this
purpose (CH1- CH 4). Charging
is displayed by the red LED.
7. As soon as the accumulators
have been charged, the charger
changes over to floating. The
green charging/discharging LED
signals floating.
"Refresh" function
A special feature of the BL 506
charger is the refresh function for
round accumulators. This function
allows to regenerate accumulators
with capacity losses (refer to "What
is the memory effect?") so that they
can form themselves again. This
function should be used, above all,
for older accumulators or those
which have not been in use for a
longer period of time.
Prior to refreshing, connect BL 506
with the mains
(230 V AC or the cigarette lighter
jack of your car/12 V DC).
1. As soon as the charger is
connected with the mains, the
yellow LED at the right will light
up for a short period of time.
2. Now set the switch to the
" REFRESH " central position.
3. Insert the accumulators onto the
compartment provided for this
purpose (CH1–CH 4), do not
press the discharging button.
4. As soon as the accumulators
have been inserted, the yellow
LED will light up and signal that
the accumulators are discharged.
This function will discharge your
accumulators completely by a
very low discharging current.
5. On completion of discharging,
the yellow LED flashes.
6. Now proceed as described in
section "Charging and
discharging".
Important: If the capacity of your
accumulators is not increased after
refreshing, it is possible that your
accumulators are damaged and
have to be replaced.
Safety notes
Caution: Never try to charge
alkaline batteries or RAM cells
(re-chargeable batteries).
Danger of explosion!
