0.5... 2.4 V (2 V battery), 0.5... 7.15 V (6 V
battery) or 0.5... 14.3 V (12 V battery).
Charging technology
The device has three different charging
phases:
• I-Phase, the charging current is approx.
0.6 A for a 12V battery and approx. 0.3A
for a 2V and 6V battery.
• U1-Phase (= Main charging phase) with
a constant voltage of 14.3 V (and/or
2.4V or 7.15V)
• U2-Phase (Trickle charge) with constant
voltage of 13.8 V (and/or 2.4V or 7.15).
The battery is first charged with a con-
stant current (I-phase) until the final char-
ge voltage (14.3 V/7.15/2.4 V) has been
reached. The voltage is then kept con-
stant (U1-Phase) and the charging current
adapts itself to the charge state of the
battery. The fuller the battery, the lower
the charging current. The charging proce-
dure is terminated and the battery charger
switches automatically into the test mode,
if a charging current of approx. 100 mA
is under run (see note N3). The battery is
loaded with a defined current during this
test. A large internal resistance and/or a
strong sulphation of the battery is indica-
ted, if the voltage of the loaded battery
thereby drops back to the rated voltage.
The battery charger evaluates the battery
as „defective", if the test is not passed;
the device then switches itself off and the
„Error" and „Finished" LED's flash.
The battery charger switches the „Finis-
hed" LED on and goes into the refresh
mode, if all test criteria have been fulfilled
after charging and the battery has been
evaluated as „Good". The „Charging"
LED extinguishes simultaneously and the
„Refresh" LED is displayed. The battery is
therefore charged and ready for use and
can be disconnected from the battery
charger.
The program discharges for 15 minutes
with a current of approx. 30mA, if the
battery however remains connected to
the battery charger. The trickle charge
procedure is started after 15 minutes or
when the battery voltage is lower than
the nominal value (appropriate to 2, 6,
12V). The „Refresh" LED thereby extin-
guishes and the „Charging" LED is turned
on. The program now supplies a „Trickle
charge" for 15 minutes. The charging cur-
rent is now adapted in such a way that
the battery voltage is automatically kept
at 13.8/6.9/2.3 V. The „Refresh" program
restarts after 15 minutes. This is repeated
cyclically until the battery charger is dis-
connected from the battery.
The operating modi:
The device can indicate three different
operating modes during operation:
1. The „Charging" LED shines. Charging.
2. The „Charging" and „Finished" LEDs
shine: Trickle charge.
3. The „Refresh" and „Finished" LEDs
shine: Refresh.
Errors:
The device can indicate four different er-
rors:
1. The „Charging" and „Error" LEDs flash:
The voltage setting (with slide switch)
and the measured battery voltage do
not correspond.
2. The „Finished" and „Error" LEDs flash:
The battery is recognised as defective.
3. The „Error" LED flashes: The slide
switch has an undefined position (In-
termediate position).
