5.6.
Forming
If one or more deep discharged batteries are inserted, the AV4m automatically tries to reach the required cell
voltage via forming. Therefore the battery is reactivated by regulated current pulses.
This process is indicated in the display by showing
“
For
“. If the forming succeeds a complete charging cycle is
started automatically. If the forming has no success and the cell cannot be reactivated (max. 30 minutes), no
charging cycle will be started and
“
Err
“ is shown in the display.
Following errors are shown for the particular charging bay if applicable:
Err
= Battery defective, cell could not be reactivated
bAd
= Internal resistance is too high, cell is dried up
In both cases the battery is damaged, therefore no more suitable and must be disposed professionally.
6. Errors and Troubleshooting
1. No indication on the display:
-Check if power supply or adapter is plugged-in in a proper way;
-Check if the cable at the charger is plugged-in in a proper way;
-Check if the cable is defective;
2. Charging does not start:
-Check if the battery is inserted reverse-poled;
3. Charging abort:
-Remove batteries and disconnect the charger for a short time;
4.
“Err“ shown in display:
-Battery deep discharged (defective)
dispose according to regulations;
5.
“bAd“ shown in display:
-Battery dried up (defective)
dispose according to regulations;
