AUTOMATIC CHARGER
Attention:
if the battery is being charged in the car, the positive cable may
not come into direct contact with the battery or the fuel line.
4.
Now connect the charger with your mains.
5.
Set the correct charging voltage according to your battery by pressing the
6 V/12 V button. The LED 6 V or 12 V will indicate the selected charging
voltage.
6.
The charging cycle will automatically start five seconds after the charging
voltage has been selected. The chosen mode will be locked to avoid an
accidental changing of the voltage. The LED
“Laden”
(charging) will light up.
A detailed information of the charging cycle is described under point 7.
7.
The battery is fully loaded when the green LED
“Fertig”
(finished) lights up
and the LED
“Laden”
switches itself off.
8.
After finishing the charging cycle disconnect charger from the mains first.
9.
Then disconnect the red terminal from the battery/vehicle body and finally
disconnect the black cable from the battery.
Please note:
if the charger does not automatically go into “maintenance
mode” after a longer period of charging the reasons might be:
– Due to the battery age there is a permanent leakage of 300 mA or larger.
– The battery is being charged in the vehicle and the connected electric
consumers are in sum using more than 300 mA.
7. CHARGING CYCLE AND LEDS
The charger has three basic charging faces:
– I-phase: the charging power is approximately 2 A
– U1-phase: (main charging phase) consent charging voltage of 14.3 V
– U2-phase: (maintenance charging phase) consent charging voltage of 13.8 V
The LEDs:
– LED
“Netz”
(power): indicates that the charger is connected to a 230 V/50
Hz power supply.
– LED
“Verpolt”
(incorrect polarity): after setting the voltage the charger will
go into test mode. If the battery is connected with the wrong polarity the
LED
”Verpolt”
will light up.
– LED
“Defekt”
(malfunction): if the voltage of the correctly connected battery is
over 14.3 V (with a 12 V battery) or over 7.15 V (with a 6 V battery) then the
LEDs
“Defekt”
and the 6/12 V LED will start blinking.
– LED
“Test”
: the battery is first charged with a constant current (I-phase) until
the charging voltage of 14.3 V/7.15 V is reached. Then the voltage is kept
constantly at this level (U1-phase) and charging current is adapted. The fuller
the battery, the lower the charging current. If the charging current is smaller
than 300 mA, charging is discontinued and the charger will automatically
switch to the test mode. The LED
“Test”
is switched on and the LED
”Laden”
is switched off. During this test the battery has a load of a defined current. If
the voltage of the charged battery falls under the nominal voltage, it can be
assumed that the battery has a high internal resistance, and that sulphation
has occurred. In this case the charger rates the battery as defective and the
LED “defekt” lights up. If the battery passes the test, the LED
“Fertig”
(finished)
will light up and the charger will go into maintenance mode (U2-phase).
– LED
“Fertig”
(finished): indicates that the battery is fully loaded.
– LED
“Erhalten”
(maintain): indicates that the fully loaded status of the battery
is maintained with a trickle charge at 13.8 V. If a charging current of 200
mA is reached, the charger will automatically switch to pause mode. The
maintenance process will then repeat itself after one hour.
The charger can display 2 errors during operation:
– The LEDs 12/6 V and
“defect”
are blinking: the battery does not match the
selected voltage.
– The LED
“defect”
lights up: the battery has a defect.
8. MAINTENANCE AND HANDLING
– Before cleaning the charger, the device must be disconnected from the battery
and from the mains. Clean the outside of the product with a clean, dry, soft
cloth. Do not use abrasive cleaners or solvent-based cleaning agents. Do not
use aggressive cleaning agents as these can cause discoloration. Solvents
and abrasive cleaners can damage the surface or erase the printing. Please
make sure that no liquids run into the charger.
– To prevent corrosion after charging, clean the terminals. Wipe off any battery
fluid that has come into contact with the terminals.
– When storing the charger, loosely role the cables together. Store the charger
in a clean dry place.
