AL 600plus 21
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. 30 mA, 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, 12 V). The „Refresh“ LED thereby
extinguishes and the „Charging“ (Laden) LED is turned on. The program now
supplies a „Trickle charge“ for 15 minutes. The charging current 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 disconnected from the battery.
The operating modi:
The device can indicate three different operating modes during operation:
1. The „Charging“ (Laden) LED shines. Charging.
2. The „Charging“ (Laden) and „Finished“ (Fertig) LEDs shine: Trickle
charge.
3. The „Refresh“ and „Finished“ (Fertig) LEDs shine: Refresh.
Errors:
The device can indicate four different errors:
1. The „Charging“ (Laden) and „Error“ (Fehler) LEDs flash:
The voltage setting (with slide switch) and the measured battery voltage
do not correspond.
2. The „Finished“ (Fertig) and „Error“ (Fehler) LEDs flash:
The battery is recognised as defective.
3. The „Error“ (Fehler) LED flashes:
The slide switch has an undefined position (Intermediate position).
4. The „Error“
(Fehler) LED shines continuously:
A charging attempt failed.
Possible cause: Battery charger or battery defective.
