9 Tabular overview of the program procedures
Step 0:
If „General Overhaul" has been selected:
Continue with step 3
If „Regular Check" or „Periodical Check" have been selected:
All cells over 1.05V?
If not: Charge with 0.1C for 1.5 hours. If polarity of cells reversed, then error message.
Step 1:
Residual Discharge with C
Step 2:
A) If "Regular check" has been selected
Deep discharge with device internal 1 Ohm resistors on each cell for 12 hours.
D
epending on settings the device might wait after executing Step 3. This will prevent,
that e.g. in the night the request to control the electrolyte level might occur.
B) If "Periodical check" has been selected
Continue with step 6
Step 3:
I-Charge with C until charging voltage of 1.57 V × number of cells is reached.

Step 4:
Topping charge (final charge) with C
In case no automatic cell tester is connected:
30 minutes before the end of the topping charge a signal requests for measurement of single cells
voltages and to control the electrolyte level.
Otherwise:
30 minutes before the end of the topping charge a signal requests to control the electrolyte level.
Step 5:
Residual discharge with C
In case no automatic cell tester is connected:
After 51 minutes a signal requests for measurement of single cells voltages.
Otherwise:
Cell measurement is performed automatically once a cell has fallen below 1.0V.
Thereafter further discharge C
Step 6:
8 hours break.
The message is displayed:
„wait 8 hours. skip waiting time possible: press
Step 7:
I-Charge with C until charging voltage of 1.57 V × number of cells is reached.
